Description

Technical Field

[0001] This utility model relates to the field of foaming machine technology, specifically to a material tank assembly for a sponge foaming machine. Background Technology

[0002] The material tank assembly of a sponge foaming machine is an important component, primarily used for storing and mixing the raw materials required for foaming. During the foaming process, the material tank assembly needs to ensure accurate proportioning, uniform mixing, and a stable supply of raw materials to guarantee consistent foaming results and stable product quality.

[0003] Common components of a sponge foaming machine include: a material tank for storing foaming raw materials; a mixer for mixing raw materials; an inlet and an outlet for inputting raw materials and outputting the foam mixture, respectively; a temperature control system for controlling the temperature inside the material tank; and a pressure control system for controlling the pressure inside the material tank.

[0004] However, this method can only rotate circumferentially when the agitator drives the mixing blades to mix, which makes it impossible to form a more complex flow path in the tank, thus reducing the mixing efficiency. Moreover, this single rotational motion will cause uneven local mixing, and cannot ensure that the material is fully mixed in multiple directions. This can easily lead to material settling and stratification at the bottom of the tank, reducing the quality of the foaming machine tank component and failing to meet the working requirements of the foaming machine. Therefore, a new material tank component for a sponge foaming machine is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a material tank assembly for a sponge foaming machine, which solves the technical problem that the mixing blades can only rotate circumferentially, resulting in the inability to form more complex flow paths within the material tank, thus reducing mixing efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a material tank assembly for a sponge foaming machine, comprising:

[0009] A base, on the upper surface of which a tank is mounted, a snap-fit ​​post is mounted at the top center of the tank, a snap-fit ​​shaft is inserted inside the snap-fit ​​post, and a first motor is mounted on the top front side of the tank via a bracket, with a first gear coaxially connected to the bottom end of the rotor of the first motor.

[0010] The second gear is coaxially mounted on the top of the insert shaft. An installation cylinder is installed at the middle of the top of the inner cavity of the tank. A shaft is inserted inside the installation cylinder. A square strip is connected to the bottom of the insert shaft, and the lower part of the square strip is inserted inside the shaft.

[0011] A stirring rod is connected to the bottom end of the shaft column. A stirring blade is installed on the lower outer side of the stirring rod. An annular groove is opened in the middle of the inner part of the mounting cylinder. A spherical protrusion is installed on the right outer side of the shaft column at a position corresponding to the annular groove.

[0012] Preferably, the first gear meshes with the second gear, and the lower part of the square strip is inserted into the shaft column to a depth of two-thirds of the shaft column height, which facilitates the up and down movement of the shaft column and prevents it from coming out of the square strip.

[0013] Preferably, the annular groove is inclined, the spherical protrusion is engaged inside the annular groove, and inlet and outlet pipes are installed on both the left and right sides of the tank to facilitate loading and unloading.

[0014] Preferably, a mounting platform is installed at the top center of the tank body. The height of the mounting platform exceeds the top end face of the first gear and the second gear to avoid interference. A swing arm is installed at the top center of the mounting platform via a bearing.

[0015] Preferably, a side connecting frame is installed at the middle of the rear of the mounting platform, and an assembly rod is connected to the bottom outer side of each swing arm. Arc-shaped through grooves are opened on the left and right sides of the top of the tank corresponding to the assembly rods. The assembly rods pass through the interior of the arc-shaped through grooves, and scrapers are installed on the lower outer side of each assembly rod.

[0016] Preferably, a second motor is installed inside the side connecting frame. A cam is coaxially connected to the top of the rotor of the second motor. A transmission link is connected to the outer side of the top of the cam through a bearing. The outer ends of the transmission link are all connected to the top left side of the swing arm through bearings. The rotation of the cam can be driven by the second motor, which in turn can drive the swing arm to swing back and forth through the transmission link. This allows the inner wall of the tank to be scraped by the scraper, which not only facilitates the cleaning of the inner wall but also improves the mixing quality.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a material tank assembly for a sponge foaming machine, which has the following beneficial effects:

[0019] The foaming machine's material tank assembly utilizes a first motor to drive a first gear, which in turn drives a second gear to rotate the insert shaft and square strips. This rotation causes the shaft and stirring rod to rotate. Simultaneously, the shaft reciprocates through the interaction of annular grooves and spherical protrusions, resulting in the stirring blades moving up and down in both circumferential and vertical directions. This creates a more complex flow path for the material within the tank, improving mixing efficiency. Furthermore, this up-and-down motion breaks down localized uneven mixing caused by single rotational motion, ensuring thorough mixing in both horizontal and vertical directions. The motion also helps prevent sedimentation at the bottom of the tank, especially for denser or easily settling materials. The up-and-down motion continuously brings material from the bottom to the top, maintaining its suspension and preventing stratification. This improves foaming quality, resulting in more uniform foam density and a more regular pore structure, ultimately enhancing product performance and appearance, and improving the overall quality of the foaming machine's material tank assembly.

[0027] 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.

[0028] This utility model provides a technical solution: a material tank assembly for a sponge foaming machine, comprising a base 1, a tank body 2, a snap-fit ​​post 3, a first motor 4, a first gear 5, a insert shaft 6, a second gear 7, a mounting cylinder 8, a square strip 9, a shaft post 10, a stirring rod 11, a stirring blade 12, an annular groove 13, a spherical protrusion 14, a mounting platform 15, a swing arm 16, an assembly rod 17, a scraper 18, an arc-shaped through groove 19, a side connecting frame 20, a second motor 21, a cam 22, and a transmission connecting rod 23.

[0029] Please see Figure 1 The tank 2 is mounted on the upper surface of the base 1. Please refer to [link / reference]. Figure 2 A snap-fit ​​post 3 is installed at the top center of tank body 2. Please refer to [link / reference]. Figure 3 The snap-fit ​​post 3 has an insert shaft 6 inserted inside. Please refer to [link / reference]. Figure 2 The first motor 4 is mounted on the front top of the tank body 2 via a bracket, and the first gear 5 is coaxially connected to the bottom of the rotor of the first motor 4.

[0030] Please see Figure 3 The second gear 7 is coaxially mounted on the top of the insert shaft 6. An installation cylinder 8 is installed at the middle position of the top of the inner cavity of the tank body 2. (See also...) Figure 4 and Figure 5 A shaft post 10 is inserted inside the mounting cylinder 8, and a square strip 9 is connected to the bottom end of the shaft 6, with the lower part of the square strip 9 inserted inside the shaft post 10.

[0031] A stirring rod 11 is connected to the bottom end of the shaft 10. A stirring blade 12 is mounted on the lower outer side of the stirring rod 11. An annular groove 13 is formed in the middle of the interior of the mounting cylinder 8. A spherical protrusion 14 is mounted on the right outer side of the shaft 10, corresponding to the annular groove 13. A first gear 5 meshes with a second gear 7. The lower part of a square strip 9 is inserted into the shaft 10 to a depth of two-thirds of the shaft 10's height. The annular groove 13 is inclined, and the spherical protrusion 14 engages within it. Inlet and outlet pipes are installed on both the left and right sides of the tank 2. The first motor 4 drives the first gear 5 to rotate, which in turn drives the insertion shaft 6 and the square strip 9 to rotate via the second gear 7, causing the shaft 10 and the stirring rod 11 to rotate. Simultaneously, the engagement of the annular groove 13 and the spherical protrusion 14... The shaft column 10 reciprocates up and down, which in turn causes the stirring blades 12 to move up and down while rotating circumferentially. This allows the material to form a more complex flow path within the tank 2, thereby improving mixing efficiency. Furthermore, this up-and-down motion can break the localized uneven mixing phenomenon caused by single rotational motion, ensuring that the material is fully mixed in both horizontal and vertical directions. At the same time, the up-and-down motion helps prevent the material from settling at the bottom of the tank 2. Especially for material components with higher density or that are easy to settle, the up-and-down motion can continuously bring the material from the bottom to the top, keeping the material in a suspended state and avoiding stratification. This can improve foaming quality, making the foam density more uniform and the pore structure more regular, thereby improving the performance and appearance quality of the product and enhancing the quality of use of the foaming machine's material tank components.

[0032] Please see Figure 1 A mounting platform 15 is installed at the top center of tank 2. Please refer to [link / reference]. Figure 6 The height of the mounting platform 15 exceeds the top end face of the first gear 5 and the second gear 7. A swing arm 16 is mounted on the top middle position of the mounting platform 15 via a bearing. A side connecting frame 20 is installed at the rear middle position of the mounting platform 15. Assembly rods 17 are connected to the bottom outer sides of the swing arm 16. Arc-shaped through grooves 19 are opened on the left and right sides of the top of the tank body 2 at positions corresponding to the assembly rods 17. The assembly rods 17 pass through the interior of the arc-shaped through grooves 19. Scrapers 18 are installed on the lower outer side of the assembly rods 17. The inner side of the side connecting frame 20... The unit is equipped with a second motor 21. The top of the rotor of the second motor 21 is coaxially connected to a cam 22. The outer side of the top of the cam 22 is connected to a transmission link 23 through a bearing. The outer ends of the transmission link 23 are all connected to the top left side of the swing arm 16 through bearings. The second motor 21 can drive the cam 22 to rotate, thereby driving the swing arm 16 to swing left and right through the transmission link 23. In turn, the scraper 18 can scrape the inner wall of the tank 2, which not only facilitates the cleaning of the inner wall, but also improves the mixing quality.

[0033] This design uses a first motor 4 to drive the first gear 5 to rotate, which in turn drives the second gear 7 to rotate the insert shaft 6 and the square strip 9, causing the shaft column 10 and the stirring rod 11 to rotate. Simultaneously, the shaft column 10 reciprocates up and down through the interaction of the annular groove 13 and the spherical protrusion 14. This allows the stirring blade 12 to move up and down while rotating circumferentially, creating a more complex flow path for the material within the tank 2, thus improving mixing efficiency. This up-and-down motion also breaks up localized uneven mixing caused by single rotational motion, ensuring thorough mixing in both horizontal and vertical directions. Furthermore, the up-and-down motion helps prevent material sedimentation at the bottom of the tank 2, especially for denser or easily settling materials. It continuously brings material from the bottom to the top, maintaining its suspension and preventing stratification. This improves foaming quality, resulting in more uniform foam density and a more regular pore structure, thereby enhancing product performance and appearance, and improving the overall quality of the foaming machine's material tank components.
