[0024] The specific embodiments of the utility model will be further described in detail below in combination with the drawings.

[0025] As shown in the drawings, Figure 1 The utility model discloses an online mixing device, which comprises a material drying machine 1, a particle feeding mechanism 2, a toner feeding mechanism 3, a mixing mechanism 4, a material conveying pipe 5 and an air pipe 6.

[0026] As shown in the drawings, Figure 2 The particle feeding mechanism 2 comprises a hopper 21, a material storage cylinder 22, a discharging cylinder 25 and a particle discharging valve 8, the material storage cylinder 22 is communicated between the hopper 21 and the discharging cylinder 25, and the material storage cylinder 22 is communicated above the discharging cylinder 25 through the particle discharging valve 8; the material drying machine 1 is communicated with the hopper 21 through the material conveying pipe 5; the hopper 21 is connected with the air pipe 6, and the air pipe 6 is connected with a negative pressure mechanism 61.

[0027] The top of the hopper 21 is provided with an openable first top cover 211, which ensures the sealing property of the hopper 21 and avoids the particles in the hopper from being damp, and the maintenance and overhaul of the hopper 21 can be carried out by opening the first top cover 211.

[0028] The negative pressure mechanism 61 generates negative pressure in the hopper 21, so that the particles in the material drying machine 1 are conveyed into the hopper 21 through the material conveying pipe 5, the particles in the hopper 21 fall into the material storage cylinder 22 below due to gravity, the opening time of the particle discharging valve 8 can be controlled, and thus the single conveying amount of the particles from the material storage cylinder 22 to the discharging cylinder 25 can be controlled.

[0029] Preferably, the material conveying pipe 5 is a hose, which is more suitable for the conveying characteristics of the plastic particles and avoids the plastic particles from colliding with the inner wall of the material conveying pipe to generate more powder dust.

[0030] A weight sensor 23 is arranged between the material storage cylinder 22 and the discharging cylinder 25, the weight sensor 23 can calculate the single discharging amount of the particles in the material storage cylinder 22 according to the weight difference before and after the single discharging of the material storage cylinder 22, and then transmit the single discharging amount to a terminal, so that the administrator can manage and debug in time, and thus the accuracy of the particle discharging amount can be improved.

[0031] Preferably, the material storage cylinder 22 is a transparent cylinder, which is convenient for the administrator to visually observe the particle storage amount in the barrel through the material storage cylinder 22 and timely supplement the material.

[0032] The sidewall of the storage cylinder 22 is provided with a storage sensing element 24, which can be an existing photoelectric sensor. The photoelectric sensor is arranged at a suitable position of the storage cylinder 22. When the particle accumulation height in the storage cylinder 22 is lower than the sensing position of the photoelectric sensor, the photoelectric sensor converts the sensed light signal into an electric signal and transmits it to the terminal. The terminal issues an instruction to the negative pressure mechanism 61 to automatically and timely supplement the storage cylinder 22 with particles.

[0033] The discharging cylinder 25 is provided with a guide slope 251. The particles in the storage cylinder 22 are transmitted along the discharging cylinder 25 to the mixing mechanism 4, and the toner enters the mixing mechanism 4 at the same time. Since the single feeding amount of the toner is small, the guide slope 251 can provide a buffering effect for the particles being transmitted downward, so as to avoid the particles from being transmitted downward too fast and facilitate the mixing of the particles and the toner.

[0034] As shown in Figure 3 The toner feeding mechanism 3 includes a toner supplement hopper 31, a toner storage bin 32, a toner feeding sensing element 33, a connecting pipe 34, and a toner discharging valve 9. The toner supplement hopper 31 is connected above the toner storage bin 32. The bottom of the toner storage bin 32 is connected with the connecting pipe 34 through the toner discharging valve 9. The toner feeding sensing element 33 is located at the bottom of the toner storage bin 32.

[0035] The toner is supplemented into the toner storage bin 32 through the toner supplement hopper 31. Since the single feeding amount of the toner is generally small, the frequency of supplementing the toner is low. The top of the toner supplement hopper 31 is provided with an openable second top cover 311. The second top cover 311 improves the sealing property of the toner supplement hopper 31, so as to avoid the toner in the toner storage bin 32 from being damp for a long time and affecting the quality of the toner.

[0036] Since the single feeding amount of the toner is small, the toner feeding sensing element 33 can be a weight sensor. The weight sensor senses the weight change of the toner storage bin 32 and the toner in real time. The start and stop of the toner discharging valve 9 are controlled through the terminal, so as to accurately control the single feeding amount of the toner.

[0037] As shown in Figure 4 The mixing mechanism 4 includes a shell 41, a rotating shaft 42, and a plurality of stirring rods 43. The top of the shell 41 is provided with a particle feeding port 411 and a toner feeding port 412. The discharging cylinder 25 is connected with the shell 41 through the particle feeding port 411. The toner storage bin 32 is connected with the toner feeding port 412 through the connecting pipe 34. The bottom of the shell 41 is provided with a discharging port 413, and the discharging port 413 is connected with a mixing discharging valve 7. The plurality of stirring rods 43 are connected in the shell 41 through the rotating shaft 42, and each stirring rod 43 is arranged on the outer wall of the rotating shaft 42 in a staggered manner.

[0038] After the toner and particles enter the shell 41, the rotating shaft 42 is connected with an existing driving device, such as a motor, and the motor drives the rotating shaft 42 to swing back and forth, and the rotating shaft 42 drives the stirring rod 43 connected therewith to swing back and forth, so as to stir the toner and particles in the shell 41.

[0039] The end of the stirring rod 43 is provided with a material inserting slope 43, which can be embedded in the accumulated material more quickly, so that the stirring rod 43 can mix the material more uniformly.

[0040] The online mixing device of the utility model, particle material is put into the material drying machine 1 in batches for drying, the material drying machine 1 is the existing drying machine, and the particles after drying are transmitted to the particle feeding mechanism 2 by negative pressure, and according to the matching parameters, the particles are quantitatively transmitted to the mixing mechanism 4 by the particle discharge valve 8; at the same time, the toner in the toner feeding mechanism 3 is also quantitatively transmitted to the mixing mechanism 4 by the toner discharge valve 9 according to the matching parameters, and after the toner and particles are fully stirred by the mixing mechanism 4, they are transmitted to the injection molding equipment from the discharge port 413 by the mixing discharge valve 7.

[0041] The above has carried out the specific description to the preferred embodiment of the utility model creation, but the utility model creation is not limited to the described embodiment, and those skilled in the art can make various equivalent modifications or replacements without violating the spirit of the utility model creation, and these equivalent modifications or replacements are all included in the range defined by the claims of the present application.
