Description

TECHNICAL FIELD

[0002] The raw materials of foamed board need to be mixed in a banburying machine to improve the physical properties of the foamed board, such as elasticity, flex resistance, etc. The temperature control of the banburying machine has an important influence on the foaming effect.

[0003] Currently, the temperature control of the banburying machine is in an overall control mode, i.e. only the temperature of the outer area of the banburying machine is monitored, and the temperature inside the raw materials cannot be detected. During actual mixing operation, the raw materials are repeatedly kneaded, and the heat is accumulated inside the materials, which cannot be effectively dissipated, resulting in a locally excessively high temperature in the center of the materials, affecting the mixing quality. There is a difference between the temperature of the center of the materials and the temperature of the inner and outer areas of the banburying machine, and the mixing process cannot be effectively monitored.

[0004] At the same time, the shear force during mixing also has a very important influence on the mixing effect. The current banburying machine disperses the raw materials through the shearing of the gear to promote the full contact and mixing between the materials. However, the gaps between the gears are uniformly distributed, and the shear force at all positions is the same. During initial mixing, only rough mixing is needed, and precise mixing is not required. The uniformly distributed shear force limits the mixing efficiency. SUMMARY

[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments; based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are merely for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0023] As shown in Figures 1-4 The present application embodiment provides a foaming plate mixing device, which comprises an inclined mixing barrel 1, the inclined mixing barrel 1 (for the convenience of display, the drawing shows a vertical state) can make the foaming raw materials gradually move downward from a high place under the action of gravity and shearing force, so as to mix the materials in different stages in the mixing barrel 1, improve the mixing efficiency, a rotating shaft 2 is provided in the center of the mixing barrel 1, the rotating shaft 2 is connected with an external driving device, a plurality of groups of mixing discs 3 are distributed on the rotating shaft 2 at intervals, the spacing between adjacent mixing discs 3 gradually changes, the gap between the mixing discs 3 closer to the high place is larger, and the material is mainly mixed at this stage to improve the mixing efficiency, and the gap between the mixing discs 3 at the bottom is smaller, mainly used for applying shearing force to the material to realize refining, the rotating shaft 2 is connected with the mixing disc 3 in the center, the rotating shaft 2 drives the mixing disc 3 to rotate, so that the mixing disc 3 shears and mixes the material.

[0024] In order to avoid heat concentration at the center position of the material and accurately control the temperature of the material at different positions, heating coils 8 are symmetrically arranged in the mixing disc 3, the temperature of the material mixing is usually controlled at about 90 degrees, and the heating coils 8 will not affect the mechanical properties of the rotating shaft 2; in order to supply power to the heating coils 8, a central wire 4 is arranged in the center of the rotating shaft 2, and the central wire 4 is connected with the heating coils 8; in order not to affect the conduction of the central wire 4 when the rotating shaft 2 rotates, a conductive slip ring 5 is arranged at the bottom of the rotating shaft 2, and the conductive slip ring 5 is connected with the central wire 4.

[0025] In order to accurately control the shear force received by the material at different positions, the upper and lower sides of the banbury disc 3 are embedded with floating discs 6, which can slide in the vertical direction relative to the banbury disc 3 to change the gap between adjacent floating discs 6. The floating discs 6 are arrayed with protrusions 7, which have different distribution radii relative to the rotating shaft 2. The rotating speed of the material at different radii is different, and the speed difference leads to the emergence of shear force. The protrusions 7 exert shear force on the material, making the physical properties of the material more excellent and the mixing effect better.

[0026] In order to make the floating discs 6 slide up and down, trapezoidal cavities 10 are provided on the circumferential side walls of the floating discs 6. The upper tapered side wall of the trapezoidal cavity 10 is provided with a first wedge rod 11, and the lower tapered side wall of the trapezoidal cavity 10 is provided with a second wedge rod 12. The first wedge rod 11 and the second wedge rod 12 are both penetratingly arranged in the banbury disc 3. The first wedge rod 11 and the second wedge rod 12 can both slide towards the center of the banbury disc 3. When the first wedge rod 11 slides towards the trapezoidal cavity 10, the first wedge rod 11 is in contact with the upper tapered side wall of the trapezoidal cavity 10, causing the floating disc 6 to move upwards. In order to prevent the floating disc 6 from separating from the first wedge rod 11 and causing the floating disc 6 to fall off, the second wedge rod 12 slides inwards synchronously, causing the second wedge rod 12 to be in contact with the lower tapered side wall of the trapezoidal cavity 10, thereby limiting the upward movement of the floating disc 6. When it is necessary to move the floating disc 6 in the opposite direction, it is only necessary to control the first wedge rod 11 and the second wedge rod 12 in the opposite direction. That is, when the first wedge rod 11 and the second wedge rod 12 work together, one plays a driving role and the other plays a safety limiting role.

[0027] In order to control the positions of the first wedge rod 11 and the second wedge rod 12, a first nut 13 is rotatably arranged on the first wedge rod 11, and a second nut 14 is rotatably arranged on the second wedge rod 12. The first nut 13 and the second nut 14 are both threadedly connected with the banbury disc 3. By rotating the first nut 13 and the second nut 14, the positions of the first wedge rod 11 and the second wedge rod 12 can be changed.

[0028] When the floating disc 6 slides up and down, there is a gap between the floating disc 6 and the banbury disc 3. In order to reduce the residue of the material in this gap, the upper and lower side walls of the banbury disc 3 are both provided with tapered slopes 9. When the material enters the gap, it will slide down from the tapered slopes 9 under the action of gravity.

[0029] In specific work, the material is poured into the banbury barrel 1 from the charging hole. The banbury barrel 1 is in an inclined state, and the material cannot directly fall to the bottom of the banbury barrel 1. The external power device is started, and the material receives less shear force at the upper end of the banbury barrel 1, so it will complete the mixing operation first, completing the rough mixing. After the mixing is completed, the fine mixing is carried out below the banbury barrel 1.

[0030] When the rotating shaft 2 rotates, the mixing disc 3 and the floating disc 6 are driven to rotate, and the rotating speeds of the materials in different regions of the floating disc 6 are different, the protrusions 7 apply shearing force to the materials, so that the physical properties of the materials are more excellent, and the mixing of the materials is promoted.

[0031] When the materials are mixed, the heating coils 8 are heated through the conductive slip ring 5 and the central wire 4, the heating coils 8 generate heat, and the materials at different positions of the floating disc 6 are heated separately, and when the materials at a certain position are overheated, the supply of the heating coil 8 at the position can be reduced.

[0032] If the shearing effect and efficiency of the materials need to be adjusted during the operation, the distance between the protrusions 7 can be changed, the first nut 13 and the second nut 14 can be rotated, the first wedge rod 11 and the second wedge rod 12 can slide, the floating disc 6 can move up and down, and the adjustment of the gap can be completed.

[0033] It should be noted that, in the present text, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0034] The above describes the utility model and its implementation, which is not limited, and the drawings only show one of the embodiments of the utility model, and the actual structure is not limited. In general, if a person skilled in the art is inspired, without departing from the creative purpose of the utility model, similar structure and embodiments can be designed without creativity, which should belong to the protection scope of the utility model.
