Description

Technical Field

[0001] This invention belongs to the field of material mixing technology, specifically referring to a raw material mixing device and method for foam materials. Background Technology

[0002] After being molded, porous materials such as foam sponge have a large number of pores and cavities inside, which require a "foaming" process. This process is mainly divided into two categories: chemical foaming and physical foaming. Chemical foaming refers to the process in which a large number of bubbles are generated during the chemical reaction itself, without the need for external air supply. Physical foaming, on the other hand, involves using an air pump to inject gas into the mixed viscous material, and then using stirring to break up the bubbles to complete the foaming process.

[0003] The mixed materials will stick to the inner wall of the mixing drum. Before the next batch of materials is mixed, the inner wall needs to be scraped off. In the existing solutions, the mixing components generally need to be disassembled and reassembled manually, which is time-consuming and labor-intensive. If an automatic cleaning and scraping structure is set up, it is usually quite complicated. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a raw material mixing device and method for foam materials. The present invention proposes a telescopic stirring component. By rotating the polygonal slide bar in both directions, the mixing mode and discharge mode of the device can be switched, the extension and retraction state of the telescopic plate can be changed, and the position of the telescopic plate can be adjusted by the rotation speed, thereby realizing the all-round stirring and mixing of the materials inside the mixing drum.

[0005] In addition, the design of the elastic vane allows for control of the rotation direction, which determines whether the elastic vane can apply longitudinal thrust toward the material.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a raw material mixing device for foam materials, including a cylinder wall scraping component, a telescopic stirring component, an elastic wing pushing component, a synchronous air supply component, a drive component, and a frame assembly. The cylinder wall scraping component is disposed on the frame assembly, the telescopic stirring component is disposed on the elastic wing pushing component, the elastic wing pushing component is disposed on the frame assembly, and the synchronous air supply component and the drive component are respectively disposed on both sides of the frame assembly.

[0007] The telescopic mixing assembly includes a polygonal slide rod, a tension spring, and a rotating support frame. The elastic wing pushing assembly includes a rotating part of a pump. The cylinder wall scraping assembly includes a mixing cylinder with a discharge port at the bottom. The rotating part of the pump is rotatably located below the discharge port. The polygonal slide rod is slidably located in the rotating part of the pump and rotates with it. The tension spring is sleeved on the polygonal slide rod, and the rotating support frame is fixed to the top of the polygonal slide rod.

[0008] Furthermore, the telescopic stirring assembly also includes a telescopic plate and an elastic element. The telescopic plate is telescopically disposed in the rotating support frame. Several groups of telescopic plates are evenly distributed in a ring. The telescopic plate is in an inclined state, and the end of the telescopic plate is provided with a sloping part.

[0009] By changing the rotation direction of the telescopic plate, the telescopic mixing component can switch between two modes: extending and retracting. Due to the tilt angle of the telescopic plate, the height of the telescopic plate in the mixing drum can also be adjusted by changing the rotation speed of the telescopic mixing component, thereby achieving the technical effect of mixing at different heights.

[0010] Furthermore, the cylinder wall scraping assembly also includes a scraping piston, the frame assembly includes a frame base, the mixing cylinder is disposed on the frame base, the scraping piston is engaged and slidably disposed in the mixing cylinder, the conical surface of the scraping piston is made of elastic material, and the conical angle of the scraping piston is greater than the conical angle of the mixing cylinder.

[0011] The top of the scraping piston is equipped with a one-way exhaust valve. When the material in the mixing cylinder is discharged from the outlet, the scraping piston will descend with the material under negative pressure, thereby scraping the inner wall of the mixing cylinder. Since the cone angle of the scraping piston is greater than that of the mixing cylinder, when the outer ring of the scraping piston first contacts the bottom of the mixing cylinder, the material adhering to the bottom of the mixing cylinder can be squeezed out as the contact area gradually increases.

[0012] Furthermore, the elastic wing pusher assembly also includes an impeller and an elastic wing. The impeller is fixed to the rotating part of the pump. The tension spring is located between the rotating support frame and the impeller. Fixed blades are evenly distributed in a ring on the impeller. The elastic wing is rotatably mounted on the fixed blades. The elastic wing is tilted upward in a free state.

[0013] During the mixing process, the elastic vane is located behind the fixed blade, so the elastic vane is in a horizontal state and does not apply longitudinal thrust to the material; during the discharging process, the elastic vane is located in front of the fixed blade, so the elastic vane is in an inclined state and can apply longitudinal thrust to the material.

[0014] Preferably, the elastic wing pushing assembly further includes a pump fixing part, the frame assembly further includes a pump support frame, the pump support frame is fixedly connected to the frame base, the pump fixing part is fixedly connected to the pump support frame, and the pump rotating part is rotatably disposed on the pump fixing part.

[0015] A fan-shaped baffle is provided between the fixed part and the rotating part of the pump. During the mixing process, the baffle is closed to prevent material from leaking out through the pump. During the discharge process, the baffle is opened to allow material to be discharged.

[0016] Furthermore, the synchronous air supply assembly includes an annular air chamber, high-pressure nozzles, an air pump, and an air supply pipe. The annular air chamber is fixed to the bottom of the material pump fixing part. Hollow rods are evenly distributed in a ring on the annular air chamber. The high-pressure nozzle array is located in the hollow rods. The air pump is located on the frame base. The air supply pipe is located between the air pump and the annular air chamber.

[0017] The air pump is also driven by a drive motor, so that the air supply speed of the air pump and the discharge speed of the material pump are automatically kept in correspondence during the foaming process.

[0018] Furthermore, the drive assembly includes a drive motor, a drive gear, a driven gear ring, and a driven gear. The drive motor is mounted on the frame base, the drive gear is mounted on the output shaft of the drive motor, and the driven gear ring is located outside the rotating part of the pump. The driven gear ring and the drive gear mesh and transmit power.

[0019] Preferably, the driven gear is located on the input shaft of the air pump, and the driven gear ring and the driven gear mesh and drive each other.

[0020] An elastic element is provided between the telescopic plate and the rotating support frame to pull the telescopic plate back.

[0021] The raw materials to be mixed are fed into the mixing drum. Then, the scraper piston is placed on top of the mixing drum and pressed down to the same height as the material surface inside the mixing drum. During the process of the scraper piston being pressed down, the air below will be discharged through the one-way exhaust valve on the scraper piston.

[0022] Step 2: Start the drive motor, which drives the rotating part of the pump to rotate through the drive gear and driven gear ring. When the rotating part of the pump rotates, it will also drive the impeller to rotate. At this time, the elastic vane is located behind the fixed blade. Under the resistance of the material, the elastic vane changes to the same horizontal angle as the fixed blade. At this time, the elastic vane does not apply longitudinal thrust to the material.

[0023] On the other hand, the rotating part of the pump will also rotate with the polygonal slide rod. When the rotating support frame rotates, the baffle between the fixed part of the pump and the rotating part of the pump closes. At this time, the material pushes the inclined part outward, and the telescopic plate will extend. Since the telescopic plate has an inclined angle, the telescopic mixing component has an upward tendency when rotating. This lift force counteracts the tension spring.

[0024] Step 3: After the telescopic plate extends, it can mix and stir the materials in the mixing drum by rotating itself and the inclined part. At the same time, changing the rotation speed of the rotating support frame can control the height of the telescopic plate, thereby achieving mixing at different depths inside the mixing drum.

[0025] Step 4: Reverse rotation drive motor. Since the polygonal slide bar rotates in the opposite direction, the telescopic plate will retract under the counter-thrust of the material on the inclined part. At the same time, the baffle between the fixed part of the pump and the rotating part of the pump opens. Since the elastic blade is located in front of the fixed blade, it is in an inclined state and can apply longitudinal thrust to the material, so that the mixed material in the mixing drum is discharged through the pump.

[0026] Step 5: During the material discharge process, the scraping piston descends with the material under negative pressure, scraping off the material adhering to the side wall of the mixing cylinder. Since the cone angle of the scraping piston is greater than that of the mixing cylinder, when the outer ring of the scraping piston first contacts the bottom of the mixing cylinder, the material adhering to the bottom of the mixing cylinder is squeezed out as the contact area gradually increases. After contacting the rotating support frame, the scraping piston can overcome the elastic force of the tension spring and press the rotating support frame down into the discharge port.

[0027] Step Six: At the same time, the air pump supplies air into the annular air chamber and sprays it out through the high-pressure nozzle. When the gas passes through the high-pressure nozzle, it will be divided into small bubbles, thus completing the air supply step in physical foaming.

[0028] The beneficial effects achieved by the present invention using the above structure are as follows:

[0029] (1) By changing the rotation direction of the telescopic plate, the telescopic stirring component can switch between two modes: extension stirring and retraction. Due to the tilt angle of the telescopic plate, the height of the telescopic plate in the mixing drum can also be adjusted by changing the rotation speed of the telescopic stirring component, thereby achieving the technical effect of stirring different height parts.

[0030] (2) A one-way exhaust valve is provided on the top of the scraping piston. When the material in the mixing cylinder is discharged from the outlet, the scraping piston will descend with the material under negative pressure, thereby scraping the inner wall of the mixing cylinder. Since the cone angle of the scraping piston is greater than that of the mixing cylinder, when the outer ring of the scraping piston first contacts the bottom of the mixing cylinder, the material adhering to the bottom of the mixing cylinder can be squeezed out as the contact area gradually increases.

[0031] (3) During the mixing process, the elastic blade is located behind the fixed blade, so the elastic blade is in a horizontal state and does not apply longitudinal thrust to the material; during the discharge process, the elastic blade is located in front of the fixed blade, so the elastic blade is in an inclined state and can apply longitudinal thrust to the material.

[0032] (4) A fan-shaped baffle is provided between the fixed part of the pump and the rotating part of the pump. During the mixing process, the baffle is closed to prevent the material from leaking out through the pump. During the discharge process, the baffle is opened to allow the material to be discharged.

[0033] (5) The air pump is also driven by a drive motor, so that the air supply speed of the air pump and the discharge speed of the material pump are automatically kept in correspondence during the foaming process. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] like Figures 1-9 As shown, the present invention proposes a raw material mixing device and method for foam materials, including a cylinder wall scraping component 1, a telescopic stirring component 2, an elastic wing pushing component 3, a synchronous air supply component 4, a drive component 5, and a frame component 6. The cylinder wall scraping component 1 is disposed on the frame component 6, the telescopic stirring component 2 is disposed on the elastic wing pushing component 3, the elastic wing pushing component 3 is disposed on the frame component 6, and the synchronous air supply component 4 and the drive component 5 are respectively disposed on both sides of the frame component 6.

[0050] The telescopic mixing assembly 2 includes a polygonal slide rod 21, a tension spring 22, and a rotating support frame 23. The elastic wing pushing assembly 3 includes a pump rotating part 34. The cylinder wall scraping assembly 1 includes a mixing cylinder 11. The bottom of the mixing cylinder 11 is provided with a discharge port 111. The pump rotating part 34 is rotatably located below the discharge port 111. The polygonal slide rod 21 is slidably located in the pump rotating part 34 and rotates with the pump rotating part 34. The tension spring 22 is sleeved on the polygonal slide rod 21. The rotating support frame 23 is fixedly connected to the top of the polygonal slide rod 21.

[0051] The telescopic mixing assembly 2 also includes a telescopic plate 24 and an elastic element 25. The telescopic plate 24 is telescopically disposed in the rotating support frame 23. Several groups of telescopic plates 24 are evenly distributed in a ring. The telescopic plate 24 is in an inclined state. The end of the telescopic plate 24 is provided with a sloping part 241.

[0052] By changing the rotation direction of the telescopic plate 24, the telescopic stirring assembly 2 can switch between two modes: extending and retracting. Due to the tilt angle of the telescopic plate 24, the height of the telescopic plate 24 in the mixing drum 11 can also be adjusted by changing the rotation speed of the telescopic stirring assembly 2, thereby achieving the technical effect of stirring at different heights.

[0053] The cylinder wall scraping assembly 1 also includes a scraping piston 12, and the frame assembly 6 includes a frame base 61. The mixing cylinder 11 is disposed on the frame base 61, and the scraping piston 12 is engaged and slidably disposed in the mixing cylinder 11. The conical part of the scraping piston 12 is made of elastic material, and the conical angle of the scraping piston 12 is greater than the conical angle of the mixing cylinder 11.

[0054] The top of the scraping piston 12 is equipped with a one-way exhaust valve. When the material in the mixing cylinder 11 is discharged from the discharge port 111, the scraping piston 12 will descend with the material under negative pressure, thereby scraping the inner wall of the mixing cylinder 11. Since the cone angle of the scraping piston 12 is greater than the cone angle of the mixing cylinder 11, when the outer ring of the scraping piston 12 first contacts the bottom of the mixing cylinder 11, the material adhering to the bottom of the mixing cylinder 11 can be squeezed out as the contact area gradually increases.

[0055] The elastic wing pusher assembly 3 also includes an impeller part 31 and an elastic wing 32. The impeller part 31 is fixed to the rotating part 34 of the pump. The tension spring 22 is located between the rotating support frame 23 and the impeller part 31. Fixed blades 311 are evenly distributed in a ring on the impeller part 31. The elastic wing 32 is rotatably mounted on the fixed blades 311. The elastic wing 32 is tilted upward in a free state.

[0056] During the mixing process, the elastic vane 32 is located behind the fixed blade 311, so the elastic vane 32 is in a horizontal state and does not apply longitudinal thrust to the material; during the discharge process, the elastic vane 32 is located in front of the fixed blade 311, so the elastic vane 32 is in an inclined state and can apply longitudinal thrust to the material.

[0057] The elastic wing pusher assembly 3 also includes a pump fixing part 33, and the frame assembly 6 also includes a pump support frame 62. The pump support frame 62 is fixed in the frame base 61, the pump fixing part 33 is fixed in the pump support frame 62, and the pump rotating part 34 is rotatably mounted on the pump fixing part 33.

[0058] A fan-shaped baffle is provided between the fixed part 33 and the rotating part 34 of the pump. During the mixing process, the baffle is closed to prevent material from leaking out through the pump. During the discharge process, the baffle is opened to allow material to be discharged.

[0059] The synchronous air supply assembly 4 includes an annular air chamber 41, high-pressure nozzles 42, an air pump 43, and an air supply pipe 44. The annular air chamber 41 is fixed to the bottom of the material pump fixing part 33. Hollow rod parts 411 are evenly distributed in an annular pattern on the annular air chamber 41. The high-pressure nozzles 42 are arrayed in the hollow rod parts 411. The air pump 43 is mounted on the frame base 61. The air supply pipe 44 is located between the air pump 43 and the annular air chamber 41.

[0060] The air pump 43 is also driven by the drive motor 51, so that the air supply speed of the air pump 43 and the discharge speed of the material pump are automatically kept in correspondence during the foaming process.

[0061] The drive assembly 5 includes a drive motor 51, a drive gear 52, a driven gear ring 53, and a driven gear 54. The drive motor 51 is mounted on the frame base 61, the drive gear 52 is mounted on the output shaft of the drive motor 51, and the driven gear ring 53 is mounted outside the rotating part 34 of the pump. The driven gear ring 53 and the drive gear 52 mesh and transmit power.

[0062] Driven gear 54 is mounted on the input shaft of air pump 43, and driven gear ring 53 and driven gear 54 mesh and transmit power.

[0063] An elastic element 25 is provided between the telescopic plate 24 and the rotating support frame 23 to pull the telescopic plate 24 back.

[0064] like Figure 10As shown, in the free state, the elastic vane 32 tilts slightly upwards, and the dashed line represents the boundary of the rotation range of the elastic vane 32. When the elastic vane 32 is behind the fixed blade 311, the elastic vane 32 will rotate to a state flush with the fixed blade 311 under the thrust of the material. When the elastic vane 32 is in front of the fixed blade 311, the elastic vane 32 will rotate to an inclined state under the thrust of the material, at which time the elastic vane 32 will apply a downward thrust to the material.

[0065] like Figure 11 As shown, an openable sector-shaped baffle is provided between the fixed part 33 of the pump and the rotating part 34 of the pump. The rotation angle of the sector-shaped baffle is equal to the angle corresponding to each sector area. Therefore, by rotating the sector-shaped baffle, the opening and closing of the channel between the fixed part 33 of the pump and the rotating part 34 of the pump can be controlled. In the mixing process, the baffle is closed to prevent material from leaking out through the pump. In the discharge process, the baffle is opened to allow material to be discharged.

[0066] In practical use, the raw materials to be mixed are fed into the mixing cylinder 11, and then the scraper piston 12 is placed on top of the mixing cylinder 11 and pressed down to the same height as the material surface inside the mixing cylinder 11. During the process of the scraper piston 12 being pressed down, the air below will be discharged through the one-way exhaust valve on the scraper piston 12.

[0067] Start the drive motor 51, which drives the pump rotating part 34 to rotate through the drive gear 52 and the driven gear ring 53. When the pump rotating part 34 rotates, it will drive the impeller part 31 to rotate. At this time, the elastic vane 32 is located behind the fixed blade 311. Under the resistance of the material, the elastic vane 32 changes to the same horizontal angle as the fixed blade 311. At this time, the elastic vane 32 does not apply longitudinal thrust to the material.

[0068] On the other hand, the rotating part 34 of the pump will also rotate along the polygonal slide bar 21. When the rotating support frame 23 rotates, the baffle between the pump fixing part 33 and the pump rotating part 34 closes. At this time, the material pushes the inclined part 241 outward, and the telescopic plate 24 will extend. Since the telescopic plate 24 has an inclined angle, the telescopic stirring assembly 2 has an upward tendency when rotating. This lift counteracts the tension spring 22.

[0069] After the telescopic plate 24 extends, it can mix and stir the material in the mixing cylinder 11 by rotating itself and the inclined part 241. At the same time, changing the rotation speed of the rotating support frame 23 can also control the height of the telescopic plate 24, thereby realizing the mixing and stirring of different depths inside the mixing cylinder 11.

[0070] The reverse rotation drive motor 51, since the polygonal slide bar 21 rotates in the opposite direction, the telescopic plate 24 will retract under the counter-thrust of the material on the inclined part 241. At the same time, the baffle between the fixed part 33 of the pump and the rotating part 34 of the pump opens. The elastic blade 32 is in an inclined state because it is located in front of the fixed blade 311, and can apply longitudinal thrust to the material, so that the material that has been mixed in the mixing drum 11 is discharged through the pump.

[0071] During the material discharge process, the scraping piston 12 descends with the material under negative pressure, and can scrape off the material adhering to the side wall of the mixing cylinder 11. Since the cone angle of the scraping piston 12 is greater than the cone angle of the mixing cylinder 11, when the outer ring of the scraping piston 12 first contacts the bottom of the mixing cylinder 11, the material adhering to the bottom of the mixing cylinder 11 can be squeezed out as the contact area gradually increases. After the scraping piston 12 contacts the rotating support frame 23, it can overcome the elastic force of the tension spring 22 and press the rotating support frame 23 down into the discharge port 111.

[0072] At the same time, the air pump 43 supplies air into the annular air chamber 41 and sprays it out through the high-pressure nozzle 42. When the gas passes through the high-pressure nozzle 42, it will be divided into small bubbles, thus completing the air supply step in physical foaming.

[0073] The material discharged from the pump contains a large number of air bubbles. Subsequent stirring action can cut and break the large air bubbles into smaller ones.

[0074] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

A method of using a raw material mixing device for foam materials, comprising the raw material mixing device for foam materials as described in claim 6, characterized in that, Includes the following steps: Step 1: Feed the raw materials to be mixed into the mixing cylinder (11), then place the scraper piston (12) on the top of the mixing cylinder (11) and press it down to the height of the material surface inside the mixing cylinder (11). During the process of pressing down the scraper piston (12), the air below will be discharged through the one-way exhaust valve on the scraper piston (12). Step 2: Start the drive motor (51), which drives the rotating part (34) of the pump to rotate through the drive gear (52) and the driven gear ring (53). When the rotating part (34) of the pump rotates, it will drive the impeller part (31) to rotate. At this time, the elastic vane (32) is located behind the fixed blade (311). Under the resistance of the material, the elastic vane (32) changes to the same horizontal angle as the fixed blade (311). At this time, the elastic vane (32) does not apply longitudinal thrust to the material. On the other hand, the rotating part (34) of the pump will also rotate with the polygonal slide bar (21). When the rotating support frame (23) rotates, the baffle between the fixed part (33) of the pump and the rotating part (34) of the pump closes. At this time, the material pushes the inclined part (241) outward, and the telescopic plate (24) will extend. Since the telescopic plate (24) has an inclined angle, the telescopic stirring assembly (2) has an upward tendency when rotating. This lift counteracts the tension spring (22). Step 3: After the telescopic plate (24) extends, it can mix and stir the material in the mixing drum (11) by rotating itself and the inclined part (241). At the same time, changing the rotation speed of the rotating support frame (23) can also control the height of the telescopic plate (24), thereby achieving mixing and stirring at different depths inside the mixing drum (11). Step 4: Reverse rotation drive motor (51). Since the polygonal slide bar (21) rotates in the opposite direction, the telescopic plate (24) will retract under the counter-thrust of the material on the inclined part (241). At the same time, the baffle between the fixed part (33) and the rotating part (34) of the pump opens. The elastic blade (32) is in an inclined state because it is located in front of the fixed blade (311), and can apply longitudinal thrust to the material, so that the material that has been mixed in the mixing drum (11) is discharged through the pump. Step 5: During the material discharge process, the scraping piston (12) descends with the material under negative pressure, which can scrape off the material adhering to the side wall of the mixing cylinder (11). Since the cone angle of the scraping piston (12) is greater than that of the mixing cylinder (11), when the outer ring of the scraping piston (12) first contacts the bottom of the mixing cylinder (11), the material adhering to the bottom of the mixing cylinder (11) can be squeezed out as the contact area gradually increases. After the scraping piston (12) contacts the rotating support frame (23), it can overcome the elastic force of the tension spring (22) and press the rotating support frame (23) down into the discharge port (111). Step 6: At the same time, the air pump (43) supplies air into the annular air chamber (41) and sprays it out through the high-pressure nozzle (42). When the gas passes through the high-pressure nozzle (42), it will be divided into small bubbles, thus completing the air supply step in physical foaming.
