Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, in particular to a raw material spreading and limiting device for an ABS plastic particle drying equipment. Background Art

[0002] ABS plastic particles are an important engineering plastic raw material. ABS plastic particles have good comprehensive properties, including relatively high strength, toughness, heat resistance and chemical corrosion resistance. It is widely used in various fields, such as automobile manufacturing, electronic appliances, toys, office supplies, etc.

[0003] When producing ABS plastic particles, it is necessary to cut the extruded strip-shaped plastic. When the extruded strip-shaped plastic is cooled, it needs to pass through a cooling pool for cooling, resulting in more moisture on the surface of the cut particles. Therefore, it is necessary to effectively dry the surface of the ABS particles. The existing drying means mainly uses hot air drying. The fine particles lack necessary limitation and will displace under the action of hot air, resulting in difficult drying of the particle surface. And the relatively thick stacked particles also greatly affect the drying effect. Summary of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a raw material spreading and limiting device for an ABS plastic particle drying equipment.

[0021] The following combines the attached drawings to elaborate on the preferred embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0022] As Figures 1-4 Shown is a raw material spreading and limiting device for an ABS plastic particle drying equipment, including a conveyor rack 1, a conveyor mesh belt 2, a limit clamping strip 3 and a feeding and spreading mechanism 4. The conveyor mesh belt 2 is sleeved on the top of the conveyor rack 1. The limit clamping strip 3 is fixedly arranged at both ends of the surface of the conveyor mesh belt 2. The feeding and spreading mechanism 4 is arranged on the top of the conveyor rack 1. The feeding and spreading mechanism 4 includes a support frame 41, a connecting seat 42, a material storage hopper 43, a discharge hopper 44, a spreading frame 45, an air inlet mesh 46, a material control seat 47, a cylinder seat 48, a cylinder 49, a lifting plate 410 and a limit stop strip 411. The support frame 41 and the connecting seat 42 are fixedly arranged on both sides of the conveyor rack 1. The material storage hopper 43 is fixedly arranged inside the top of the support frame 41. The discharge hopper 44 is fixedly arranged at the bottom of the material storage hopper 43. The spreading frame 45 is fixedly arranged inside the top of the connecting seat 42. The air inlet mesh 46 is arranged on the top of the spreading frame 45. The material control seat 47 is arranged between the spreading frame 45 and the discharge hopper 44. The cylinder seat 48 is fixedly arranged on the top of the material control seat 47. The cylinder 49 is installed inside the top of the cylinder seat 48. The lifting plate 410 is fixedly arranged at the telescopic end of the cylinder 49. The limit stop strip 411 is fixedly arranged at the bottom of both ends of the spreading frame 45.

[0023] Specifically, one end of the limit stop strip 411 has a horn-shaped structure. A slot matching the limit clamping strip 3 is opened at the bottom of the limit stop strip 411. The limit stop strip 411 is clamped on the top of the limit clamping strip 3. The top of the material control seat 47 is inclined downward. The bottom of the lifting plate 410 penetrates and extends to the inside of the top of the material control seat 47. Air inlet holes are opened at the top of the spreading frame 45. The air inlet mesh 46 is arranged inside the air inlet holes at the top of the spreading frame 45. Discharge holes are opened at the bottom and one side of the discharge hopper 44. The connection between the discharge hopper 44 and the material control seat 47 is in an open form.

[0024] In this embodiment, the conveyor belt 2 mounted on the surface of the conveyor frame 1 is in the form of a mesh cloth, which is mainly conducive to the evaporation of moisture in the particles and the drainage work. The entire feeding and spreading mechanism 4 is fixed to the outside of the conveyor frame 1 through the support frame 41 outside the storage hopper 43 and the connecting seat 42 outside the spreading frame 45 to play a supporting role. During use, the wet ABS plastic particles are poured into the storage hopper 43, and the wet ABS particles are discharged from the discharge holes at the bottom of the lower discharge hopper 44 to the surface of the conveyor belt 2. At this time, the ABS particles will be transported to the material control seat 47. The cylinder 49 inside the top of the cylinder seat 48 controls the lifting plate 410 to make reciprocating movements, so as to separate the particles transported into the material control seat 47 into a ridge-like structure. In this way, when entering the spreading frame 45 after passing through the material control seat 47, they will be better spread and flattened by the spreading frame 45, and the drying work will be better carried out.

[0025] Further, when the spread particles pass through the air inlet net 46, since the limit stop bar 411 is clamped on the top of the limit card bar 3, the two sides of the conveyor belt 2 are effectively blocked, and the air inlet net 46 effectively blocks the top of the particles, ensuring that the particles are effectively limited during hot air drying, avoiding the random scattering of particles caused by air flow, reducing the particle drop, and ensuring the drying effect.

[0026] It should be noted that the parts not involved in the present invention are the same as or can be implemented by the prior art; various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in cooperation with connecting rods, guide rods, etc., and are not limited to the descriptions in the specification and the structures in the drawings.
