Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, in particular to an EPP particle forming automobile bumper core material production device. Background Art

[0002] As we all know, EPP is the abbreviation of a new type of polypropylene foam plastic. It is a highly crystalline polymer with excellent performance. EPP material has become the fastest growing environmentally friendly new type of pressure-resistant buffer and heat-insulating material due to its unique and superior performance. At the same time, EPP material is also an environmentally friendly material and can be recycled and reused. EPP material is usually granular. It has the advantages of light specific gravity, good elasticity, shock and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-water absorption, insulation, heat resistance, non-toxic and odorless, and can fix the outer panel 0% for recycling with almost no performance degradation. EPP is widely used in automobile bumper core materials, anti-collision blocks, ceiling linings, door fillings, headrests, sun visors and other fields.

[0003] When EPP materials are processed and produced as core materials for automobile bumpers, multiple raw materials such as polypropylene (PP) resin, foaming agent, antioxidant, diluent (such as acetone), cross-linking agent, and co-cross-linking agent need to be mixed.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0030] like Figures 3 to 5As shown, an EPP particle molding automobile bumper core material production equipment of the present invention includes a spherical shell box 1, a plurality of first spherical panels 2 are provided on the circumferential outer wall of the spherical shell box 1 on a horizontal plane, and a second spherical panel 3 is provided at the bottom of the spherical shell box 1. The spherical shell box 1, the plurality of first spherical panels 2 and the second spherical panel 3 form a closed spherical shape, and the interior of the sphere is used to store raw materials. The first spherical panel 2 and the second spherical panel 3 are both rotatably connected to the spherical shell box 1;

[0031] A plurality of diffusion flow plates 4 are obliquely mounted on the inner wall of the first spherical panel 2 , and a plurality of convergence flow plates 5 are obliquely mounted on the inner wall of the second spherical panel 3 .

[0032] Specifically, the spherical shell type box body 1 has an opening facing upward, and raw materials can be added into the sphere through the opening. The spherical shell type box body 1 is rotated with the vertical axis of the spherical shell type box body 1 as the rotation axis, and the spherical shell type box body 1 drives the first spherical panel 2 to rotate synchronously in a circular manner, and the second spherical panel 3 remains fixed. The rotating spherical shell type box body 1 and multiple first spherical panels 2 can drive the raw materials inside the sphere to rotate and flow, and at the same time, the first spherical panel 2 rotates, and the first spherical panel 2 drives multiple diffusion flow plates 4 thereon to rotate synchronously. The multiple diffusion flow plates 4 can stir the raw materials inside the sphere, and at the same time, the diffusion flow plates 4 can divert the raw materials inside the sphere, so that the raw materials near the inner wall of the first spherical panel 2 diffuse and flow outward, and at the same time, the raw materials in the sphere Part of the raw material can flow along the axis of the first spherical panel 2 toward the inner wall of the first spherical panel 2, thereby forming a tumbling flow state of the raw material inside the sphere, making it convenient for the raw material to follow the spherical shell type box 1 to rotate in a circle while being stirred and guided by the diffusion flow plate 4. The raw material tumbles and flows in the spherical shell type box 1. Since the spherical shell type box 1 and the second spherical panel 3 produce relative rotation, the gathering guide plate 5 and the raw material in the spherical shell type box 1 produce relative rotation. The raw material in the flowing state can enter the gathering guide plate 5 and be gathered toward the middle of the second spherical panel 3 through the guiding effect of the inner wall of the gathering guide plate 5. The raw material gathered in the middle of the second spherical panel 3 then flows toward the middle of the spherical shell type box 1, thereby realizing a continuous tumbling flow state of the raw material.

[0033] In actual operation, since there are no corner positions inside the sphere composed of the spherical shell box 1, the first spherical panel 2 and the second spherical panel 3, the sedimentation of raw materials is avoided. However, the inner wall of traditional barrel-shaped equipment has corner positions, which easily cause the raw materials to sediment at this position or have poor fluidity, resulting in the inability to mix the raw materials evenly and comprehensively. The present invention can maintain uniform fluidity of the raw materials inside the sphere, avoid raw material sedimentation, and improve the uniformity of raw material mixing.

[0034] By adopting the spherical structure to drive the raw materials to flow in a circular manner, the sedimentation of the raw materials inside the sphere can be avoided. The structure of the first spherical panel 2, the second spherical panel 3, the diffusion flow plate 4 and the convergence drainage plate 5 can realize the tumbling flow state of the raw materials, thereby making the raw materials flow in multiple forms, effectively improving the diversity of the raw material flow forms, improving the uniformity of raw material mixing, facilitating the rapid blending of the raw materials, increasing the mixing speed, and improving the functionality of the equipment.

[0035] like Figure 2 、 Figure 6 and Figure 7 As shown, as a preferred embodiment of the above embodiment, a fixed spherical shell 6 is provided in the middle of the spherical shell type box 1, and a plurality of stirring shafts 7 are rotatably mounted on the fixed spherical shell 6. The stirring shafts 7 are along the radial direction of the fixed spherical shell 6. A plurality of gears 8 are provided inside the fixed spherical shell 6. The plurality of gears 8 form a planetary gear structure. The gears 8 are fixedly connected to the stirring shaft 7, and a plurality of stirring rods 9 are fixed on the outer wall of the stirring shaft 7.

[0036] Specifically, since the multiple gears 8 in the fixed spherical shell 6 form a planetary gear structure, when one gear 8 is rotated, the multiple gears 8 can rotate synchronously, thereby driving the multiple stirring shafts 7 to rotate synchronously, and the stirring shafts 7 drive the multiple stirring rods 9 thereon to rotate. Since the stirring shafts 7 are along the radial direction of the fixed spherical shell 6, and the structure of the multiple gears 8 is a planetary structure, the multiple stirring shafts 7 on the fixed spherical shell 6 can extend outward in multiple directions. When the raw material follows the spherical shell type box body 1 for circular motion, the raw material flows between the multiple stirring shafts 7. The multiple stirring shafts 7 and the multiple stirring rods 9 can comprehensively stir the raw materials at different positions and heights in the spherical shell type box body 1, thereby improving the comprehensiveness and uniformity of the raw material stirring.

[0037] like Figure 1 As shown, as a preferred embodiment of the above embodiment, it also includes a fixed outer panel 10, which is located on the outside of the spherical shell type box body 1, and is fixedly connected to the second spherical panel 3. A motor 11 is installed on the top of the fixed outer panel 10, and a transmission wheel 12 is installed on the output end of the motor 11. A support ring 13 is fixed on the top of the spherical shell type box body 1, and the support ring 13 is rotatably installed on the top of the fixed outer panel 10. The outer wall of the transmission wheel 12 contacts and is transmission-connected to the top of the support ring 13.

[0038] Specifically, by providing a fixed outer plate 10, the second spherical panel 3, the spherical shell box 1 and the first spherical panel 2 can be conveniently supported, and the fixed outer plate 10 can fix the second spherical panel 3, so that the second spherical panel 3 is always in a stationary state. The motor 11 drives the support ring 13 to rotate through the transmission wheel 12, and the support ring 13 can drive the spherical shell box 1 to rotate in a circular motion, so that the raw materials in the sphere flow in a circular motion.

[0039] like Figure 1 As shown, as a preferred embodiment of the above embodiment, it also includes a transmission gear ring 14, and a plurality of rolling gear rings 15 are meshed at the bottom of the transmission gear ring 14, and the rolling gear rings 15 are mounted on the outer wall of the first spherical panel 2. A plurality of first mounting plates 16 are fixed on the top of the transmission gear ring 14, and the top of the first mounting plate 16 is fixed on the fixed outer plate 10.

[0040] In this embodiment, when the spherical shell housing 1 drives the first spherical panel 2 to rotate in a circular motion, the first spherical panel 2 drives the rolling gear ring 15 to roll on the transmission gear ring 14, thereby causing the first spherical panel 2 to rotate on its own, thereby realizing the dual motion form of the first spherical panel 2, namely, circular motion and rotational motion.

[0041] like Figure 2 As shown, as a preferred embodiment of the above, a first support column 17 is fixed to the bottom of the fixed spherical shell 6, and the bottom of the first support column 17 is fixed to the second spherical panel 3. A second support column 18 is provided on the top of the fixed spherical shell 6. The bottom of the second support column 18 is rotatably inserted into the fixed spherical shell 6 and is transmission-connected to the gear 8 in the fixed spherical shell 6. A second mounting plate 19 is installed on the top of the second support column 18, and the second mounting plate 19 is fixed to the inner wall of the spherical shell-type box 1.

[0042] In this embodiment, the second spherical panel 3 drives the fixed spherical shell 6 to be in a fixed state through the first support column 17. When the spherical shell type box body 1 rotates, the spherical shell type box body 1 drives a gear 8 in the fixed spherical shell 6 to rotate through the second mounting plate 19 and the second support column 18, so that the multiple gears 8 are in a synchronous rotation state, which facilitates the multiple stirring shafts 7 and multiple stirring rods 9 to stir the raw materials.

[0043] like Figure 2 As shown, as a preference of the above embodiment, the second mounting plate 19 is U-shaped, and the cross-sectional shape of the second mounting plate 19 is conical.

[0044] In this embodiment, by setting the shape of the second mounting plate 19 to be U-shaped, the second mounting plate 19 can be prevented from colliding with the stirring shaft 7 and the stirring rod 9 on the fixed spherical shell 6, thereby providing sufficient operating space for the stirring shaft 7 and the stirring rod 9. By setting the cross-section of the second mounting plate 19 to be conical, the second mounting plate 19 can be prevented from obstructing the raw materials when the raw materials are poured into the spherical shell box body 1 through the opening of the spherical shell box body 1, thereby facilitating the raw materials to smoothly pass through the conical surface of the second mounting plate 19 and fall into the sphere.

[0045] like Figure 8As shown, as a preferred embodiment of the above embodiment, a plurality of discharge ports 20 are provided on the outer wall of the first support column 17, a material guide pipe 21 is installed at the bottom of the second spherical panel 3, the material guide pipe 21 is connected to the discharge port 20, a sealing ring 22 is provided on the sliding sleeve of the outer wall of the first support column 17, and the sealing ring 22 blocks the discharge port 20, and a plurality of first cylinders 23 are provided on the second spherical panel 3, and the movable end of the first cylinder 23 is connected to the outer wall of the sealing ring 22.

[0046] In this embodiment, when the raw materials inside the sphere are mixed, the first cylinder 23 pushes the sealing ring 22 to move upward, so that the sealing ring 22 stops blocking the discharge port 20, and the raw materials are discharged to the external collection device through the discharge port 20 and the guide pipe 21. By adopting the structure of the discharge port 20, the guide pipe 21, the sealing ring 22 and the first cylinder 23, the raw materials can always be in the inside of the sphere during the stirring operation, which is convenient for comprehensive stirring of the raw materials. The traditional method of using the guide pipe 21 and the valve can easily cause part of the raw materials to be deposited in the guide pipe 21 and the valve, resulting in the inability to comprehensively stir the raw materials.

[0047] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a third mounting plate 24 is fixed to the top of the fixed outer plate 10, a chute plate 25 is fixed to the outer end of the third mounting plate 24, the chute plate 25 is kept vertical, a slider 26 is slidingly provided in the chute plate 25, a movable plate 27 is fixed to the outer end of the slider 26, a connecting plate 28 is rotatably provided on the outer end of the movable plate 27, a supporting plate 29 is fixed to the bottom of the movable plate 27, the bottom of the connecting plate 28 is in contact with the top of the supporting plate 29, the supporting plate 29 lifts and limits the connecting plate 28, and a leaf spring 30 is connected between the movable plate 27 and the connecting plate 28;

[0048] A plurality of conical tooth blocks 31 are provided on the outer wall of the top opening of the spherical shell type box body 1, a cover plate 32 is provided above the spherical shell type box body 1, and a plurality of conical tooth blocks 31 of the same structure are provided on the inner wall of the cover plate 32, and the conical tooth blocks 31 on the spherical shell type box body 1 and the conical tooth blocks 31 on the cover plate 32 are staggered, and a connecting ring 33 is provided on the top of the cover plate 32, the connecting ring 33 is rotatably connected to the cover plate 32, and the connecting ring 33 is fixedly connected to the connecting plate 28, and a connecting shaft 34 is rotatably installed on the top of the connecting plate 28, and a second cylinder 35 is provided at both ends of the connecting shaft 34, and the fixed end of the second cylinder 35 is rotatably mounted on the fixed outer plate 10.

[0049] In this embodiment, when it is necessary to add raw materials to the inside of the sphere, the second cylinder 35 pushes the connecting plate 28 upward through the connecting shaft 34, and the connecting plate 28 drives the slider 26 to slide upward in the slide plate 25 through the leaf spring 30, the supporting plate 29 and the moving plate 27. At this time, the connecting plate 28 drives the cover plate 32 to move upward synchronously through the connecting ring 33, and the cover plate 32 is separated from the top opening of the spherical shell box 1. When the slider 26 moves to the top of the slide plate 25, the slider 26 stops moving, and the second cylinder 35 pushes the cover plate 32 to flip, so that the cover plate 32 rotates and deviates from the spherical shell box 1 The top opening makes it convenient for raw materials to be poured into the sphere through the opening of the spherical shell box 1. At this time, the connecting plate 28 rotates on the movable plate 27, and the connecting plate 28 pushes the leaf spring 30 to elastically deform. When the raw materials are added, the second cylinder 35 pulls the cover plate 32 to move in the opposite direction to the initial position. The cover plate 32 is re-installed on the top opening of the spherical shell box 1, and the conical tooth block 31 in the cover plate 32 is inserted between the two adjacent cover plates 32 on the top opening of the spherical shell box 1. When the spherical shell box 1 rotates, the spherical shell box 1 drives the cover plate 32 to rotate on the connecting ring 33 through the conical tooth block 31.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
