Detailed Implementation
[0032] Currently, when plastic granules are mixed in a mixer to form ultra-low hardness thermoplastic elastomer raw materials, the raw materials are in a gel-like state. When the mixer conveys the gel-like ultra-low hardness thermoplastic elastomer raw materials to the extruder, the ultra-low hardness thermoplastic elastomer raw materials tend to accumulate at the discharge port of the mixer and the discharge port of the receiving funnel. This leads to blockages in the downward conveying of the ultra-low hardness thermoplastic elastomer raw materials, affecting the production efficiency of ultra-low hardness thermoplastic elastomers.
[0033] In view of this, this application provides a material forming system for processing ultra-low hardness thermoplastic elastomers. By dividing the double-headed variable-diameter helical blades into a first, second, and third helical section from top to bottom, with the pitch of the first, second, and third helical sections decreasing sequentially, this three-stage variable-pitch design increases the downward pressure of the double-headed variable-diameter helical blades on the material, facilitating the flow of ultra-low hardness thermoplastic elastomer raw materials from the mixer's outlet. When the receiving funnel is full of ultra-low hardness thermoplastic elastomer raw materials... During material feeding, a pressing component slidably connected inside the receiving funnel provides downward pressure to the material, facilitating the entry of ultra-low hardness thermoplastic elastomer raw material from the receiving funnel into the extruder for the next process. This solves the technical problem in the prior art where, when the mixer feeds gel-like ultra-low hardness thermoplastic elastomer raw material to the extruder, the ultra-low hardness thermoplastic elastomer raw material tends to accumulate at the discharge port of the mixer and the discharge port of the receiving funnel, causing blockage in the downward conveying of the ultra-low hardness thermoplastic elastomer raw material and affecting the production efficiency of ultra-low hardness thermoplastic elastomer.

[0039] This application provides a material forming system for processing ultra-low hardness thermoplastic elastomers, such as... Figures 1 to 5 As shown. A material forming system for processing ultra-low hardness thermoplastic elastomers includes a mixer 1 and an extruder 2. The mixer 1 is equipped with a stirring device and a first discharge port 4, which is located at the bottom of the mixer 1.
[0040] In this embodiment, the mixing drum of the mixer 1 is conical.
[0041] The extruder 2 is provided with a receiving funnel 3 at one end near the mixer 1, and the receiving funnel 3 is connected to the first discharge port 4.
[0042] In this embodiment, the cross-section of the receiving funnel 3 is an inverted right-angled trapezoid, and its right-angled surface is connected to the first discharge port 4.
[0043] The mixing device includes a drive motor, a rotating shaft 23, and a double-headed variable-diameter spiral blade. The drive motor is located at the top of the mixer 1. The rotating shaft 23 is located inside the mixer 1 and is connected to the drive motor for transmission. The double-headed variable-diameter spiral blade is welded to the rotating shaft 23. The leading edge of the double-headed variable-diameter spiral blade is provided with a 15° downward tilt angle. The double-headed variable-diameter spiral blade includes a first spiral blade 5, a second spiral blade 6, and a third spiral blade 7 connected in sequence. The pitch of the first spiral blade 5, the second spiral blade 6, and the third spiral blade 7 decreases sequentially.
[0044] Specifically, the diameter of the mixer 1 is defined as D(z), and the diameter of the double-headed variable diameter spiral blade is defined as d(z). Then, D(z) and d(z) satisfy 0.5D(z)≤d(z)≤0.7D(z).
[0045] Specifically, by setting a 15° downward inclination angle at the leading edge of the double-headed variable-diameter spiral blades, a downward component force is provided to the material during rotation, thereby pushing the material downward along the axial direction of the rotating shaft 23. This prevents the material from being thrown outward due to centrifugal force during mixing, effectively "restricting" the material to the central area. This increases the axial pushing force of the double-headed variable-diameter spiral blades on the material. Furthermore, the three-stage variable-pitch structure formed by the first spiral blade 5, the second spiral blade 6, and the third spiral blade 7 creates a stepped pressure gradient, further increasing the axial pressure transmission efficiency. The diameter D(z) of the mixer 1 specifically refers to the diameter of the mixing drum of the mixer 1, i.e., the diameter of the mixing drum varies with the axial direction. The diameter of the double-headed variable-diameter helical blade changes with the axial height, where d(z) represents the change in diameter of the double-headed variable-diameter helical blade with the change in axial height. Specifically, the diameter ratio of the first helical blade 5 and the second helical blade 6 to the diameter of the stirring drum at the same height is 0.6-0.7, and the diameter ratio of the third helical blade 7 to the diameter of the stirring drum at the same height is 0.5-0.6. By setting D(z) and d(z) to satisfy 0.5D(z)≤d(z)≤0.7D(z), the mixing effect of the material is guaranteed while reducing the power consumption of the stirring device and increasing the downward pressure of the stirring device on the material. The drive motor is connected to the rotating shaft 23 through a coupling and a reducer.
[0046] The receiving funnel 3 is equipped with a pressing component that slides inside to provide downward pressure to the material in the receiving funnel 3, so that the material can enter the extruder 2 from the receiving funnel 3.
[0047] Specifically, the pressing assembly includes a first pressing plate 10, a second pressing plate 11, a gantry bracket 17, an L-shaped lever 18, and a pressing connecting rod 19. One end of the first pressing plate 10 is provided with a first slider 12, and the other end is provided with a sliding cavity 13. The first pressing plate 10 is slidably connected to the end of the receiving funnel 3 away from the first discharge port 4 via the first slider 12. One end of the second pressing plate 11 is slidably fitted into the sliding cavity 13, and the other end is provided with a second slider 14. The second pressing plate 11 is slidably connected to the end of the receiving funnel 3 near the first discharge port 4 via the second slider 14. A plurality of return springs 15 are provided in the sliding cavity 13. One end of the spring 15 is connected to the first pressure plate 10, and the other end is connected to the second pressure plate 11. The gantry bracket 17 is fixedly welded to the outside of the receiving funnel 3, and a rotating shaft 20 is provided on it. The long arm end of the L-shaped lever 18 is provided with a rotating support hole 21. The L-shaped lever 18 is rotatably connected to the rotating shaft 20 through the rotating support hole 21. The short arm of the L-shaped lever 18 is hinged to one end of the pressure connecting rod 19. The other end of the pressure connecting rod 19 is connected to the first pressure plate 10. The L-shaped lever 18 is used to drive the pressure connecting rod 19 to press down, so as to drive the first pressure plate 10 and the second pressure plate 11 to press down synchronously, thereby squeezing the material toward the extruder 2.
[0048] The second slider 14 is disposed at the end of the second pressure plate 11 near the first discharge port 4. Preferably, to prevent the second pressure plate 11 from colliding with the first discharge port 4 when it is pressed down, the end of the second pressure plate 11 near the first discharge port 4 is provided with a rectangular notch. The end of the receiving funnel 3 away from the first discharge port 4 is provided with an inclined groove, which is slidably connected to the first slider 12. The end of the receiving funnel 3 near the first discharge port 4 is provided with a vertical groove, and the second slider 14 is slidably connected to the vertical groove. The first slider 12, the second slider 14, the oblique slide groove, and the vertical slide groove are all provided in pairs to improve the sliding guidance capability. In use, by lifting the long arm of the L-shaped lever 18, the L-shaped lever 18 rotates around the rotating shaft 20, so that the short arm of the L-shaped lever 18 presses the first pressure plate 10 downward through the pressure connecting rod 19. At the same time, the first pressure plate 10 also presses the second pressure plate 11 downward. The first pressure plate 10 and the second pressure plate 11 are both made of 316 stainless steel, and their bottom surfaces are mirror polished to prevent material adhesion.
[0049] In some preferred embodiments, the first spiral blade 5 and the second spiral blade 6 are provided with a plurality of guide plates 8 at equal intervals along the direction of the spiral line, and the third spiral blade 7 is provided with a plurality of guide holes 9 alternately along the direction of the spiral line. By providing the guide plates 8 and the guide holes 9, it is beneficial to enhance the downward pressure on the material while maintaining the mixing effect.
[0050] In some preferred embodiments, the bottom of the first pressure plate 10 is provided with a guide oblique protrusion 16, which is used to guide the material coming out of the first discharge port 4 to the bottom of the receiving funnel 3. The guide oblique protrusion 16 is made of 316 stainless steel and its bottom surface is mirror polished to prevent the material from sticking to the guide oblique protrusion 16.
[0051] In some preferred embodiments, a grip sleeve 22 is provided on the long arm of the L-shaped lever 18. The grip sleeve 22 is provided with several anti-slip grooves and is made of silicone rubber. By providing the grip sleeve 22, the temperature of the L-shaped lever 18 is effectively isolated and the grip comfort is improved.
[0052] In summary, the material forming system for processing ultra-low hardness thermoplastic elastomers provided in this application embodiment divides the double-headed variable-diameter spiral blades into a first, second, and third spiral blade section from top to bottom, with the pitch of the first, second, and third spiral blade sections decreasing sequentially. This three-stage variable-pitch design increases the downward pressure of the double-headed variable-diameter spiral blades on the material, facilitating material flow from the mixer's outlet. When the receiving funnel is full of material, a pressing component slidably connected inside the receiving funnel provides downward pressure, facilitating the material's entry into the extruder for the next process. This solves the technical problem in the prior art where, when the mixer feeds gel-like ultra-low hardness thermoplastic elastomer raw materials to the extruder, the raw materials tend to accumulate at the mixer's outlet and the receiving funnel's outlet, causing blockages in the downward conveying of the ultra-low hardness thermoplastic elastomer raw materials and affecting the production efficiency of ultra-low hardness thermoplastic elastomers.
