Description

Technical Field

[0001] This invention relates to the field of raw material mixing technology for foam materials, and in particular to a raw material mixing device for the development of ultra-low density beaded foam materials. Background Technology

[0002] In the research and development of ultra-low density beaded foam materials, the precise mixing of raw materials is a key step that determines the final material properties (such as cell structure, density distribution, and mechanical properties). This process usually requires the use of specialized mixing equipment to fully and uniformly mix various liquid or powdered raw materials (such as polymers, foaming agents, nucleating agents, modifiers, etc.).

[0003] Currently, most widely used raw material blending equipment relies on mechanical stirring. The spatial arrangement of the core stirring components (such as impellers and screws) in this type of equipment (including their installation height relative to the bottom of the container, the spacing between each layer of impellers, and the immersion depth) is usually fixed and determined by the initial design or installation settings of the equipment. This fixed spatial distribution means that the effective range of the stirring components (i.e., their effective stirring area) is also relatively fixed during equipment operation.

[0004] However, a significant characteristic of the materials development phase is the frequent adjustment and optimization of raw material formulations and proportions. This adjustment directly leads to substantial differences in the amount of raw materials input during a single mixing operation. This fluctuation in material quantity raises a critical issue: the thickness of the material layer within the mixing vessel changes significantly accordingly.

[0005] When the amount of material input is small, the material layer formed inside the container is thin. At this time, the relatively high-positioned stirring components (such as the upper blades) may not be able to contact the material, or can only contact a very shallow layer of material. This directly leads to these stirring components "idling" to a large extent, failing to effectively participate in the mixing process, resulting in energy waste, reducing overall stirring efficiency, and making it difficult to ensure the uniformity of the material (especially the surface material).

[0006] When a large amount of material is added: the material layer thickness increases significantly, and relatively low-positioned stirring components (such as impellers near the bottom of the container) are deeply buried in the material. This leads to a sharp increase in flow resistance in the localized area, potentially causing excessive shearing, localized overheating, or poor flow in that area. Simultaneously, the upper layer of material may not be fully mixed due to insufficient stirring intensity. The overall result is uneven distribution of stirring energy and decreased mixing uniformity.

[0007] To address the aforementioned issues, this application proposes a raw material blending device for the development of ultra-low density beaded foam materials. Summary of the Invention

[0008] The purpose of this invention is to provide a raw material blending device for the development of ultra-low density beaded foam materials, so as to solve the problems mentioned in the background art.

[0009] The technical solution of this invention is: a raw material blending device for the development of ultra-low density beaded foam materials, comprising a device support, a blending tank disposed above the device support, and further comprising:

The multiple vertical rods move through the top of the guide rail rod, and the bottom end of the vertical rod is fixedly connected to the uppermost slider.

[0013] A receiving assembly is disposed between the equipment support and the mixing tank.

[0014] Preferably, a plurality of connecting ribs are slidably installed in the annular settling trough, and the plurality of connecting ribs are fixed at the opening of the mixing tank.

[0015] Preferably, the drive assembly includes a drive motor fixed to the top frame, and the output shaft of the drive motor movably passes through the top frame and is fixedly connected to an output shaft rod. An auger blade is fixed on the output shaft rod. Multiple pairs of cavity rods are fixedly installed on the outer peripheral wall of the conveying cylinder, and a pair of sliding rods are fixed on one side of each side plate. The sliding rods are slidably connected to the cavity rods, and a spring is fixedly connected between the sliding rods and the cavity rods.

[0016] Preferably, multiple corrugated membranes are slidably installed inside the guide rod, and the multiple corrugated membranes are respectively fixed between the fixed block and multiple sliders, as well as between the guide rod and the slider located at the top.

[0017] Preferably, a drive gear is fixed on the output shaft of the drive motor, a driven gear ring is fixed on the inner circumferential wall of the rotating ring plate, and a transmission gear is fixedly installed on the bottom side of the top frame near the output shaft rod. The transmission gear meshes with both the drive gear and the driven gear ring.

[0018] Preferably, the outer peripheral wall of the mixing tank is fixed with a ring frame, and the outer peripheral wall of the ring frame is fixed with symmetrically arranged connecting blocks. The inner bottom of the equipment support is fixed with two pairs of end cylinders, and piston rods are slidably installed inside the two pairs of end cylinders in the vertical direction. The top end of the piston rod is fixedly connected to the connecting block, and a support spring is fixedly connected between the bottom of the piston rod and the inner bottom of the end cylinder.

[0019] Preferably, each pair of end cylinders is fixedly connected to a connecting pipe at one end near the bottom, and an L-shaped end pipe is fixedly connected to one side of the connecting pipe. A transmission column is slidably installed on the inner wall of the L-shaped end pipe, and a return spring is fixedly connected between the transmission column and the L-shaped end pipe. A push rod is fixed to the end of the transmission column. The connecting pipe and the L-shaped end pipe are filled with hydraulic oil, and each end cylinder is fixed to the equipment support with a clamp.

[0020] Preferably, the receiving assembly includes a conveyor belt disposed below the mixing tank, a pair of idler roller frames are fixed on one side of the equipment support, and idler rollers are rotatably mounted on the idler roller frames, with the conveyor belt sleeved on the outside of the idler rollers.

[0021] Preferably, ratchet wheels are fixedly installed at both ends of the roller, and multiple equally spaced top teeth are rotatably installed on the surface of the push rod via a torsion spring shaft, with a limit stop plate fixedly installed on one side of each top tooth.

[0022] Preferably, the bottom of the mixing tank is tapered, and a pair of lifting rods are fixed to one end of the outer peripheral wall of the mixing tank near the bottom. A bottom sealing plate is rotatably installed between the pair of lifting rods via a movable shaft, and a hydraulic rod is connected to one side of the bottom sealing plate and the outer wall of the mixing tank via a hinge.

[0023] This invention provides an improved raw material blending device for the development of an ultra-low density beaded foam material, which has the following improvements and advantages compared with the prior art:

[0024] Firstly, in this invention, the height of the stirring support rod can be automatically adjusted according to the amount of material, avoiding idling. When the amount of material increases, the mixing tank presses down on the piston rod due to its weight, compressing the support spring and reducing the height of the mixing tank. At this time, the position of the vertical rod is fixed, and the top slider is pulled up to expand the stirring support rod, increasing the mixing range to the full height of the material. Conversely, when the amount of material decreases, the support rod is folded up, thus completely solving the energy waste problem of traditional fixed mixers idling when there is insufficient material.

[0025] Secondly, in this invention, zero-residue material feeding is achieved through the side plate and rubber scraper. During feeding, the material is reduced, and the trapezoidal block is pushed during the folding process of the stirring support rod, which forces the side plate to move towards the tank wall. The rubber scraper rotates and scrapes the material closely against the inner wall of the mixing tank, preventing the material from sticking to the wall. At the same time, it can avoid the rubber scraper from being in contact with the inside of the mixing tank for a long time, which can effectively reduce the wear of the rubber scraper.

[0026] Thirdly, the conveyor belt runs automatically during material feeding, avoiding material accumulation. During the feeding stage, the weight of the mixing tank is reduced, the support spring pushes the piston rod upward, the hydraulic oil flows back to the end cylinder through the connecting pipe, and the reset spring pulls the transmission column back. At this time, the push rod's top tooth pushes the ratchet to rotate in one direction, driving the idler roller to drive the conveyor belt. During the feeding stage, the tank body increases in weight and presses down the piston rod, the hydraulic oil pushes the transmission column to extend, and the top tooth slides past the ratchet without triggering rotation. The conveyor belt only runs during feeding, saving energy and preventing material accumulation. Attached Figure Description

[0038] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0039] This invention provides an improved raw material blending device for the development of ultra-low density beaded foam materials. The technical solution of this invention is as follows:

[0040] like Figures 1 to 8 As shown, this embodiment of the invention provides a raw material blending device for the development of ultra-low density beaded foam materials, including a device support 1, a blending tank 2 disposed above the device support 1, and further including:

[0041] The mixing assembly includes a conveying cylinder 5 disposed inside the mixing tank 2, and an annular settling groove 701 is provided on the outer peripheral wall of the conveying cylinder 5 near the top position. Multiple guide rods 501 are fixed on the outer peripheral wall of the conveying cylinder 5, and a fixing block 502 is fixed at the bottom of the guide rod 501. Multiple sliders 503 are slidably installed inside the guide rod 501. A stirring support rod 504 is rotatably installed on one side of the fixing block 502 and the slider 503 through a movable shaft, and the ends of two adjacent stirring support rods 504 are connected through a movable shaft.

[0042] Multiple side panels 602, each with a rubber scraper 604 fixed to its back, and multiple trapezoidal blocks 603 fixed to the other side of each side panel 602;

[0043] The top frame 3 is fixed to the equipment support 1. A drive assembly is installed on the top frame 3. A rotating ring plate 406 is rotatably installed on the bottom side of the top frame 3, and multiple vertical rods 13 are fixedly connected to the bottom side of the rotating ring plate 406. The multiple vertical rods 13 move through the top of the guide rod 501. The bottom end of the vertical rod 13 is fixedly connected to the uppermost slider 503. With the above structure, using the set mixing tank 2, when there is more material inside, its height relative to the top frame 3 is lower. At this time, the vertical rods 13 will pull the uppermost slider 503 to keep its height unchanged, while the fixed block 502 moves downward with the conveying cylinder 5. At this time, the set stirring support rod 504 will unfold to increase the distribution range in the vertical direction, so as to match the height of the material.

[0044] Conversely, the less material is added, the lower the degree of deployment of the stirring support rod 504, in order to adapt to the lower material height; in summary, the degree of deployment of the stirring support rod 504 can be matched with the amount of material added, avoiding the situation where part of the stirring structure is idle, so as to make full use of the stirring structure and improve the stirring effect.

[0045] Finally, during the material mixing and discharge process, the material in the mixing tank 2 gradually decreases, causing the stirring support rod 504 to gradually fold up. During this process, the stirring support rod 504 can gradually contact the trapezoidal block 603, eventually causing the side plate 602 to move closer to the inner wall of the mixing tank 2. When the rubber scraper 604 on one side of the side plate 602 contacts the inner wall of the mixing tank 2, it can scrape it, thereby ensuring that the material is discharged completely.

[0046] The side plate 602 and rubber scraper 604 can also play a good auxiliary stirring role during rotation, reduce the stirring dead corners, and help improve the stirring effect.

[0047] The receiving component is located between the equipment support 1 and the mixing tank 2. The receiving component is used to receive the material fed into the mixing tank 2.

[0048] Furthermore, multiple connecting ribs 7 are slidably installed inside the annular settling trough 701, and the multiple connecting ribs 7 are fixed at the opening of the mixing tank 2; by using the connecting ribs 7 in conjunction with the annular settling trough 701, the conveying cylinder 5 can be supported, and at the same time, the conveying cylinder 5 can rotate relative to the connecting ribs 7 and the mixing tank 2.

[0049] Furthermore, the drive assembly includes a drive motor 4 fixed to the top frame 3, and the output shaft of the drive motor 4 movably passes through the top frame 3 and is fixedly connected to an output shaft rod 401. An auger blade 402 is fixed on the output shaft rod 401. Multiple pairs of cavity rods 6 are fixedly installed on the outer peripheral wall of the conveying cylinder 5, and a pair of sliding rods 601 are fixed on one side of each side plate 602. The sliding rods 601 are slidably connected to the cavity rods 6, and a spring is fixedly connected between the sliding rods 601 and the cavity rods 6. With the above structure, when the drive motor 4 is running, it can drive the output shaft rod 401 to rotate and drive the auger blade 402 to rotate. In conjunction with the conveying cylinder 5, it can effectively improve the flowability of materials in the vertical direction and avoid material deposition.

[0050] Furthermore, multiple corrugated membranes 12 are slidably installed inside the guide rod 501. The multiple corrugated membranes 12 are respectively fixed between the fixed block 502 and multiple sliders 503, and between the guide rod 501 and the slider 503 located at the top. The corrugated membranes 12 can adapt to the movement of the slider 503, while preventing material from entering the guide rod 501.

[0051] Furthermore, such as Figure 7 As shown, a drive gear 403 is fixed on the output shaft of the drive motor 4, a driven gear ring 405 is fixed on the inner circumferential wall of the rotating ring plate 406, and a transmission gear 404 is fixedly installed on the bottom side of the top frame 3 near the output shaft rod 401. The transmission gear 404 meshes with both the drive gear 403 and the driven gear ring 405. With the above structure, when the drive motor 4 is running, it can drive the output shaft rod 401 to rotate, and through the transmission action of the drive gear 403, the transmission gear 404 and the driven gear ring 405, it can drive the rotating ring plate 406 to rotate in the opposite direction to the output shaft rod 401.

[0052] As a further embodiment of the present invention, such as Figures 1-5 As shown, a ring frame 201 is fixed to the outer peripheral wall of the mixing tank 2, and symmetrically arranged connecting blocks 202 are fixed to the outer peripheral wall of the ring frame 201. Two pairs of end cylinders 8 are fixed to the inner bottom of the equipment support 1, and piston rods 802 are slidably installed in the vertical direction inside the two pairs of end cylinders 8. The top of the piston rod 802 is fixedly connected to the connecting block 202, and a support spring 805 is fixedly connected between the bottom of the piston rod 802 and the inner bottom of the end cylinder 8. The end cylinders 8, piston rods 802 and support springs 805 can support the mixing tank 2. At the same time, the more material inside the mixing tank 2, the higher the degree of compression of the support spring 805, so that the height of the mixing tank 2 is lower.

[0053] Furthermore, each pair of end cylinders 8 is connected to a connecting pipe 803 near the bottom, and an L-shaped end pipe 804 is fixedly connected to one side of the connecting pipe 803. A transmission column 9 is slidably installed on the inner wall of the L-shaped end pipe 804. A return spring 806 is fixedly connected between the transmission column 9 and the L-shaped end pipe 804. A push rod 901 is fixed to the end of the transmission column 9. The connecting pipe 803 and the L-shaped end pipe 804 are filled with hydraulic oil. Each end cylinder 8 is fixed to the equipment support 1 with a clamp 801. With the above structure, when the piston rod 802 inside the end cylinder 8 moves downward, it can use hydraulic action to push the transmission column 9 to extend outward along the end of the L-shaped end pipe 804. Conversely, when the piston rod 802 moves upward, the transmission column 9 retracts into the L-shaped end pipe 804.

[0054] Furthermore, such as Figures 1-4 As shown, the receiving assembly includes a conveyor belt 10 disposed below the mixing tank 2. A pair of idler roller frames 111 are fixed on one side of the equipment support 1, and the idler rollers 11 are rotatably mounted on the idler roller frames 111. The conveyor belt 10 is sleeved on the outside of the idler rollers 11. It should be noted that a tension roller is provided at the other end of the conveyor belt 10. This structure is prior art and is not shown in the figures of this application. When the conveyor belt 10 rotates, it can horizontally transport the material placed down from the mixing tank 2 for easier collection.

[0055] Furthermore, ratchet 112 is fixedly installed at both ends of the idler roller 11, and multiple evenly distributed top teeth 902 are rotatably installed on the surface of the push rod 901 via a torsion spring shaft, and a limiting plate 903 is fixedly installed on one side of each top tooth 902; the limiting plate 903 ensures that when the push rod 901 moves back with the transmission column 9, it can smoothly push the ratchet 112 to rotate, thereby driving the idler roller 11 and the conveyor belt 10 to rotate, realizing continuous feeding and avoiding material accumulation on the conveyor belt 10 during unloading; at the same time, since the weight of the mixing tank 2 decreases only during unloading, the mixing tank 2 together with the piston rod 802 is reset under the action of the support spring 805, and the transmission column 9 is retracted under the action of hydraulic pressure and the reset spring 806; therefore, the conveyor belt 10 will rotate continuously during the unloading process to avoid material accumulation;

[0056] On the other hand, when materials are added to the mixing tank 2, the piston rod 802 gradually descends under the action of weight, and under the action of hydraulic pressure, the transmission column 9 extends, as shown in the attached... Figure 4 As shown, at this time, the top tooth 902 will deflect along the torsion spring shaft and will not be able to drive the ratchet 112 to rotate, thereby ensuring the unidirectional operation of the conveyor belt 10 to achieve centralized feeding.

[0057] As a further embodiment of the present invention, such as Figure 1 and Figure 6As shown, the bottom of the mixing tank 2 is tapered. A pair of lifting rods 141 are fixed to one end of the outer peripheral wall of the mixing tank 2 near the bottom. A bottom sealing plate 14 is rotatably installed between the pair of lifting rods 141 via a movable shaft. A hydraulic rod 142 is connected to one side of the bottom sealing plate 14 and the outer wall of the mixing tank 2 via a hinge. With the above structure, the bottom sealing plate 14 can be pushed and pulled by the hydraulic rod 142, so that it can rotate along the movable shaft, thereby flexibly controlling the feeding of the mixing tank 2.

[0058] The specific working method is as follows: When in use, the drive motor 4 starts, and the output shaft 401 drives the auger blade 402 to rotate, conveying the material from the bottom of the mixing tank 2 upwards; at the same time, the drive gear 403 meshes with the driven gear ring 405 through the transmission gear 404, causing the rotating ring plate 406 to rotate in the opposite direction. At this time, the rotating ring plate 406, together with the vertical rod 13, drives the slider 503 to slide along the guide groove rod 501; at this time, the stirring support rod 504 unfolds and rotates; as the raw materials increase, the weight of the mixing tank 2 increases, and the mixing tank 2 causes the piston rod 802 to press down the hydraulic oil in the end cylinder 8. At this time, the support spring 805 is compressed, the height of the mixing tank 2 decreases, while the position of the vertical rod 13 is fixed, pulling the top slider 503 upwards, increasing the unfolding angle of the stirring support rod 504, covering the entire material layer; during this process, the corrugated membrane 12 inside the guide groove rod 501 extends and retracts with the slider 503 to prevent the material from entering the guide groove rod 501;

[0059] After the material is mixed, the hydraulic rod 142 retracts, pulling the bottom sealing plate 14 to rotate around the movable shaft. At this time, the material can flow out from the bottom of the mixing tank 2. When the material decreases, the height of the mixing tank 2 will rise again. At this time, the stirring support rod 504 folds up and pushes the trapezoidal block 603, causing the side plate 602 to move towards the tank wall until the rubber scraper 604 is tightly attached to the inner wall and rotates to scrape the material.

[0060] On the other hand, with the weight of the mixing tank 2 reduced, the support spring 805 pushes the piston rod 802 upward, the hydraulic oil flows back through the connecting pipe 803, the reset spring 806 pulls the transmission column 9 to retract, the top tooth 902 of the push rod 901 pushes the ratchet 112 to rotate, the idler roller 11 drives the conveyor belt 10 to run and transport the material away; the set limit plate 903 ensures that the top tooth 902 pushes the ratchet 112 only in one direction; when feeding material, the transmission column 9 extends, and the top tooth 902 slides past the ratchet 112 without triggering rotation;

[0061] After the material feeding is completed, the hydraulic rod 142 pushes the bottom sealing plate 14 to close, the weight of the mixing tank 2 is reduced, the piston rod 802 returns to the initial height under the action of the support spring 805, and the stirring support rod 504 is folded up.

[0062] The foregoing description enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
