Description

Technical Field

[0001] This invention relates to a high-temperature thermoplastic toughening agent processing equipment and method, belonging to the technical field of plastic material processing equipment. Background Technology

[0002] When processing high-temperature thermoplastic materials, toughening agent granules need to be added to the main material granules and mixed evenly to assist the subsequent twin-screw extruder in uniformly distributing the toughening agent in the raw material blank. However, existing auxiliary mixers directly pour the main material granules and toughening agent granules into the mixer for high-speed mixing. Due to the large amount of main material granules and the small amount of toughening agent granules, it is found that it is difficult to uniformly distribute the toughening agent granules among the main material granules during actual processing. As a result, the raw material blank after extrusion in the twin-screw extruder still shows uneven distribution of toughening agent in the raw material blank. To address the above problems, this invention proposes a high-temperature thermoplastic material toughening agent processing equipment and processing method. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a processing equipment and method for toughening agents of high-temperature thermoplastic materials, so as to solve the existing problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a high-temperature thermoplastic toughening agent processing equipment and processing method, the structure of which includes a frame, a mixing collection box is installed in the middle of the frame, and a fractional mixing mechanism is installed in the middle of the upper end of the cavity of the mixing collection box. A batch discharge plate is fitted with a transverse gap at the lower end of the fractional mixing mechanism. A heating partition for the material box, which is horizontally installed in the middle of the cavity of the mixing collection box, is connected to the bottom surface of the batch discharge plate. A discharge agitator extending into the lower cavity of the mixing collection box is vertically installed in the middle of the heating partition. A plurality of raw material tank bodies fixed to the top surface of the mixing collection box are connected to the lower side of the fractional mixing mechanism. The number of each raw material tank body is 3-5. A twin-screw extruder body is transversely connected to the lower end of the mixing collection box.

[0005] The component mixing mechanism includes a feeding ball seat assembly and a fixed base. A mixing ball box assembly is fitted into the cavity of the feeding ball seat assembly with a gap. The upper end of the mixing ball box assembly extends to the middle of the top surface of the mixing collection box and is fitted onto the fixed base. A mixing agitator is fitted into the cavity of the mixing ball box assembly. The upper end of the mixing agitator extends to the middle of the top surface of the mixing collection box and is fitted onto the fixed base. The mixing ball box assembly and the upper right side of the mixing agitator are synchronously driven by a motor through a double-row gear meshing.

[0006] A further improvement is that the feed ball seat assembly includes a vertical seat, and the lower end of the vertical seat is connected to an upper hemispherical seat, and the lower end of the upper hemispherical seat is fitted with a lower hemispherical seat. After the upper hemispherical seat and the lower hemispherical seat are fitted together, the internal cavity forms a spherical rotating cavity, and a first rotating channel is opened between the upper end of the spherical rotating cavity and the middle part of the vertical seat.

[0007] A further improvement is that the upper hemispherical seat has multiple first feed holes that are staggered and spaced apart on its spherical surface and are sequentially connected to the lower end of each raw material tank body for feeding.

[0008] The lower hemisphere has a through-hole in the middle of its bottom surface for the discharge pipe to pass through the lower end of the mixing ball box assembly and extend downwards.

[0009] A further improvement is that the mixing sphere box assembly includes an upper hemisphere box, the upper end of which passes through the first rotating channel and is fitted with a first bearing and a first driven gear at a distance at the top, and the lower end of the upper hemisphere box is fitted with a lower hemisphere box. After the upper and lower hemisphere boxes are fitted together, the internal cavity forms a circular component mixing chamber.

[0010] A further improvement is that the lower spherical surface of the upper hemispherical box is provided with a plurality of second feed holes that are staggered and spaced apart, which are used to intermittently connect with the first feed hole to the component feeding in the circular component mixing chamber during rotation. The diameter of the second feed hole is 2-3 mm larger than the diameter of the first feed hole.

[0011] The gap between the outer wall of the circular component mixing chamber and the inner wall of the spherical rotating cavity is 1-1.5 mm;

[0012] The lower hemisphere box has an eccentric discharge pipe vertically arranged at the middle of its lower end, which is connected to the circular component mixing chamber. The top surface of the circular component mixing chamber has a second rotating channel through which the upper end of the mixing agitator passes.

[0013] A further improvement is that the mixing agitator is composed of a rotating shaft, a second driven gear, a second bearing, and multiple stirring blades. The rotating shaft passes vertically through the middle of the second rotating channel, and each of the stirring blades is located in the middle of the circular component mixing chamber.

[0014] The first driven gear, the second driven gear, and the double-row gear are sequentially meshed and connected.

[0015] A further improvement is that the batch discharge plate includes an annular discharge plate, and the top surface of the annular discharge plate is provided with an intermittent discharge groove in an annular pattern in the middle, and a plurality of first discharge ports are provided at intervals on the bottom of the annular groove of the intermittent discharge groove.

[0016] A gap of 1-1.5mm is left between the bottom of the eccentric discharge pipe and the bottom of the intermittent discharge trough.

[0017] A further improvement is that the heating partition of the material box includes a circular box plate, and multiple heating lamps of different diameters are spaced on the bottom surface of the circular box plate, and multiple second discharge ports corresponding to and connected to the first discharge port are spaced on the top surface of the circular box plate. A discharge agitator through-hole for the discharge agitator assembly is provided in the middle of the circular box plate.

[0018] A further improvement is that the mixing and collecting box, the discharge agitator, the main body of the raw material tank, and the twin-screw extruder body are all existing technologies, and their structures will not be described in detail here.

[0019] A further improvement is that valves are installed on both the main body of the raw material tank and the mixing aggregate box.

[0020] A further improvement is that the heating lamp is a constant temperature heating lamp, and the heating temperature of the constant temperature heating lamp is 10-45°.

[0021] Furthermore, this invention also provides a processing method for the above-mentioned high-temperature thermoplastic toughening agent processing equipment: the processing method is as follows:

[0022] First, pour the various raw materials and toughening agents that need to be mixed evenly into their respective raw material tanks.

[0023] Then, during the component mixing, the motor is started to drive the mixing ball box group and the mixing agitator to rotate synchronously. Then, the valves on the main body of the raw material tank are opened in sequence, and the raw materials and toughening agents will flow to the first feed hole in sequence. When the second feed hole overlaps and connects with the first feed hole during the rotation process, the raw materials and toughening agents will flow into the circular component mixing chamber in proportion, and be evenly mixed by the rotating agitator blades, and then flow out downward from the eccentric discharge pipe.

[0024] When the mixed material flows out of the eccentric discharge pipe to the lower end, the rotating eccentric discharge pipe will only discharge the mixed material downward into the cavity at the lower end of the mixing collection box when it overlaps and connects with the first discharge port. The heating lamp will heat the material so that the newly fed mixed material is slightly sticky, forming batches of uniformly mixed material.

[0025] After the component mixing mechanism completes the component mixing, the discharge valve at the bottom of the mixing collection box is opened, allowing the uniformly mixed material to be discharged from bottom to top into the twin-screw extruder body for high-temperature thermoplastic material extrusion. This results in a high-temperature thermoplastic material blank with uniformly distributed toughening agent, completing the uniform distribution extrusion process of toughening agent within the high-temperature thermoplastic material.

[0026] The beneficial effects of this invention are:

[0027] This invention provides a high-temperature thermoplastic toughening agent processing equipment and method. The equipment comprises a component mixing mechanism consisting of a feeding ball seat assembly, a mixing ball box assembly, a mixing agitator, a fixed base, and a motor. This mechanism, along with a batch discharge plate and a heating partition in the material box, is structurally integrated with the mixing collection box, the discharge agitator, and the main body of the raw material tank. When the main body of each raw material tank discharges material, the intermittent connection between the rotating mixing ball box assembly and the feeding ball seat assembly ensures that the material is fed proportionally into the circular component mixing chamber, where it is uniformly mixed in small quantities by the synchronously rotating mixing agitator. After mixing, the material is discharged downwards. The rotating discharge at the lower end of the feed ball seat assembly can also achieve multi-point discharge to different positions in the lower cavity of the mixing collection box. This makes the heating partition of the material box more efficient and convenient in heating the toughening agent particles in the same batch of uniformly mixed material to achieve slight adhesion. It avoids the problem of the toughening agent particles being covered by the next batch of material before being processed due to slight adhesion. Through the above processing technology, the toughening agent mixed and stirred is more evenly distributed in the raw material particles. This makes it easier for the toughening agent in the raw material billet obtained by subsequent extrusion processing in the twin-screw extruder body to be evenly distributed, thus improving the processing quality.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] Please see Figures 1-9 This invention provides a high-temperature thermoplastic toughening agent processing equipment and method: its structure includes a frame 1, a mixing collection box 2 is fitted in the middle of the frame 1, and a fractional mixing mechanism 3 is fitted in the middle of the upper end of the cavity of the mixing collection box 2. A batch discharge plate 4 is fitted with a horizontal gap at the lower end of the fractional mixing mechanism 3. A heating partition 5 for horizontally fitting in the middle of the cavity of the mixing collection box 2 is connected to the bottom surface of the batch discharge plate 4. A discharge agitator 6 for extending into the lower cavity of the mixing collection box 2 is vertically fitted in the middle of the heating partition 5. Multiple raw material tank bodies 7 fixed to the top surface of the mixing collection box 2 are connected to the lower side of the fractional mixing mechanism 3. The number of raw material tank bodies 7 is 3-5. The lower end of the mixing collection box 2 is horizontally connected to the twin-screw extruder body 8. The component mixing mechanism 3 includes a feed ball seat assembly 31 and a fixed seat 34. The cavity of the feed ball seat assembly 31 is fitted with a mixing ball box assembly 32. The upper end of the mixing ball box assembly 32 extends to the middle of the top surface of the mixing collection box 2 and is fitted onto the fixed seat 34. The cavity of the mixing ball box assembly 32 is fitted with a mixing agitator 33. The upper end of the mixing agitator 33 extends to the middle of the top surface of the mixing collection box 2 and is fitted onto the fixed seat 34. The upper right side of the mixing ball box assembly 32 and the mixing agitator 33 are synchronously driven by a motor 35 through a double row gear 351.

[0039] The feed ball seat assembly 31 includes a vertical seat 311, and the lower end of the vertical seat 311 is connected to an upper hemispherical seat 312. The lower end of the upper hemispherical seat 312 is fitted with a lower hemispherical seat 313. After the upper hemispherical seat 312 and the upper hemispherical seat 313 are fitted together, the internal cavity forms a spherical rotating cavity 314. A first rotating channel 315 is provided between the upper end of the spherical rotating cavity 314 and the middle part of the vertical seat 311.

[0040] The upper hemispherical seat 312 has multiple first feed holes 3121 that are staggered and spaced apart on the spherical surface and are sequentially connected to the lower end of each raw material tank body 7 for feeding. The lower hemispherical seat 313 has a discharge pipe through-hole 3131 in the middle of the bottom surface for the lower end of the mixing ball box group 32 to pass through and extend downward.

[0041] The mixing sphere box assembly 32 includes an upper hemispherical box 321, the upper end of which passes through the first rotating channel 315 and is fitted with a first bearing 322 and a first driven gear 323 at a distance from the top. The lower end of the upper hemispherical box 321 is fitted with a lower hemispherical box 324. After the upper hemispherical box 321 and the lower hemispherical box 324 are fitted together, the internal cavity forms a circular component mixing chamber 325.

[0042] The upper hemispherical box 321 has multiple staggered second feed holes 3211 on its lower spherical surface for intermittently connecting with the first feed hole 3121 to feed the components into the circular component mixing chamber 325 during rotation. The diameter of the second feed hole 3211 is 2-3 mm larger than that of the first feed hole 3121. The gap between the outer wall of the circular component mixing chamber 325 and the inner wall of the spherical rotating cavity 314 is 1-1.5 mm. The lower hemispherical box 324 has an eccentric discharge pipe 3241 vertically arranged at the lower middle of its lower end, which communicates with the circular component mixing chamber 325. The top surface of the circular component mixing chamber 325 has a second rotating channel 3251 through which the upper end of the mixing agitator 33 passes.

[0043] The mixing agitator 33 is composed of a rotating shaft 331, a second driven gear 332, a second bearing 333, and a plurality of stirring blades 334. The rotating shaft 331 passes vertically through the middle of the second rotating channel 3251, and each of the stirring blades 334 is located in the middle of the chamber of the circular component mixing chamber 325. The first driven gear 323, the second driven gear 332, and the double-row gear 351 are sequentially meshed and connected.

[0044] The batch discharge plate 4 includes an annular discharge plate 41, and an intermittent discharge groove 42 is provided in the middle of the top surface of the annular discharge plate 41 in an annular pattern. Multiple first discharge ports 43 are provided at intervals on the bottom of the annular groove of the intermittent discharge groove 42. A gap of 1-1.5mm is left between the bottom of the eccentric discharge pipe 3241 and the bottom of the intermittent discharge groove 42.

[0045] The heating partition 5 of the material box includes a circular box plate 51, and a plurality of heating lamps 52 of different diameters are spaced on the bottom surface of the circular box plate 51. A plurality of second discharge ports 53 corresponding to and communicating with the first discharge port 43 are spaced on the top surface of the circular box plate 51. A discharge agitator through-hole 54 for the discharge agitator 6 is provided through the middle of the circular box plate 51.

[0046] Working principle:

[0047] First, pour the various raw materials and toughening agents that need to be mixed evenly into their respective raw material tank bodies 7.

[0048] It should be noted that the raw materials can be fed into several raw material tanks 7, and the diameter of the discharge pipe on the raw material tank 7 containing the raw materials will be larger than the diameter of the discharge pipe on the raw material tank 7 containing the toughening agent, thereby controlling the amount of raw materials and toughening agent in the same batch.

[0049] Then, during the component mixing, the motor 35 is started to drive the mixing ball box group 32 and the mixing agitator 33 to rotate synchronously. Then, the valves on the raw material tank body 7 are opened in sequence, and the raw materials and toughening agents will flow to the first feed hole 3121 in sequence. When the second feed hole 3211 overlaps and connects with the first feed hole 3121 during the rotation process, the raw materials and toughening agents will flow into the circular component mixing chamber 325 in proportion, and be evenly mixed and stirred by the rotating stirring blades 334, and then flow out downward from the eccentric discharge pipe 3241.

[0050] The motor 35 drives the mixing ball box assembly 32 and the mixing agitator 33 to rotate synchronously in an intermittent manner. This ensures that when the second feed hole 3211 overlaps and connects with the first feed hole 3121, there is enough time for feeding. Furthermore, because the gap between the outer wall of the circular component mixing chamber 325 and the inner wall of the spherical rotating cavity 314 is designed to be 1-1.5mm, which is smaller than the diameter of the raw material and toughening agent particles, when the second feed hole 3211 is misaligned with the first feed hole 3121, the feeding can be intermittently shut off, causing the raw material and toughening agent particles to pause at the first feed hole 3121.

[0051] When the mixed material flows out of the eccentric discharge pipe 3241 to the lower end, the mixed material will only be discharged downward into the cavity at the lower end of the mixing collection box 2 when the rotating eccentric discharge pipe 3241 overlaps and connects with the first discharge port 43. The heating lamp 52 will heat the material so that the newly fed mixed material is slightly sticky, forming batches of uniformly mixed material.

[0052] Because of the 1-1.5mm gap between the bottom of the eccentric discharge pipe 3241 and the bottom of the intermittent discharge trough 42, when the eccentric discharge pipe 3241 rotates to the bottom of the intermittent discharge trough 42, the uniformly mixed material will first stay at the lower end of the eccentric discharge pipe 3241, preventing leakage. The eccentric discharge pipe 3241 will then carry this batch of uniformly mixed material to the next first discharge port 43 for discharge, ensuring that each batch of uniformly mixed material is not discharged to the same place in the lower cavity of the mixing collection box 2, achieving multi-point diversion. This facilitates the heating lamp 52 to heat the toughening agent, causing it to slightly adhere to the same batch of raw materials. It should be noted that the heating lamp 52 only heats toughening agents with low melting points to prevent large pieces of material from sticking together.

[0053] After the component mixing mechanism 3 has completed the component mixing, the discharge valve at the lower end of the mixing collection box 2 is opened, so that the uniformly mixed material is discharged from bottom to top into the twin-screw extruder body 8 for high-temperature thermoplastic material extrusion, and a high-temperature thermoplastic material blank with uniform toughening agent is obtained, thus completing the uniform distribution of toughening agent in the high-temperature thermoplastic material extrusion process.

[0054] It should be noted that the discharge agitator 6 will only be activated for low-speed auxiliary discharge when material jamming occurs during the natural downward discharge of material from the mixing collection box 2 to the twin-screw extruder body 8.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
