Description

Technical Field

[0001] This invention relates to the field of material preparation equipment technology, and in particular to a preparation equipment for processing plastic raw materials. Background Technology

[0002] Plastic raw materials are polymers, also known as macromolecules or macromolecules, and are commonly referred to as plastics or resins. In the production of plastics, plastic raw materials are composed of various plastic ingredients and additives. Since plastic raw materials are mostly granular, the processing not only requires mixing of these ingredients and additives, but also screening and dust removal to ensure the quality of the produced plastic products.

[0003] For example, a Chinese patent with authorization announcement number CN215790952U discloses a stirring device for processing plastic raw materials, including a stirring device body, a blower fixedly installed on one side of the stirring device body, a dust collection pipe fixedly installed on the other side of the stirring device body, an inclined plate fixedly installed on one side of the inner cavity of the stirring device body, and a working motor fixedly installed on the side of the stirring device body located at the bottom of the dust collection pipe. This utility model has the advantages of removing dust from the raw materials before stirring and screening out raw materials with small volume.

[0004] Although the technical solutions in the aforementioned patent documents address the mixing and dust removal during plastic raw material processing, the method of using a blower to remove dust adhering to the raw materials using strong airflow is not ideal. When a large amount of granular plastic raw material enters the mixing device simultaneously during mixing, a simple blower cannot efficiently clean the dust from the plastic raw material, thus affecting the product quality of the plastic raw material during the production of plastic products.

[0005] Therefore, how to process material preparation equipment is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figure 1-2 As shown, the present invention discloses a formulation device for processing plastic raw materials, comprising a base plate 1, with a pretreatment device and a mixing device mounted on the top of the base plate 1. The mixing device 3 is located to the right of the pretreatment device, and the pretreatment device and the mixing device 3 are connected via a guide component 6. The pretreatment device includes a pretreatment tank 2, with a drive motor 7 mounted on its back. A rotating shaft is mounted on the output end of the drive motor 7, with one end of the shaft extending into the interior of the pretreatment tank 2 away from the drive motor 7, and a mixing impeller 4 is mounted thereon. A filter assembly 5 is located inside the pretreatment tank 2 below the mixing impeller 4, and the filter assembly 5 is connected to the rotating shaft via a linkage component.

[0026] The filter assembly 5 includes a screening plate 51, with a corrugated plate 52 symmetrically arranged at the bottom of the screening plate 51, and an adjusting member 53 arranged below the corrugated plate 52. A support member 54 is symmetrically arranged at the top of the adjusting member 53, and the support member 54 is in movable contact with the corrugated plate 52.

[0027] In this embodiment, multiple support columns are provided on the bottom outer walls of both the pretreatment tank 2 and the mixing device 3, and the bottom ends of the support columns are fixedly connected to the base plate 1.

[0028] In this embodiment, a cabinet door made of transparent material is provided on the front shell wall of the pretreatment box 2.

[0029] In this embodiment, a water inlet pipe for water intake is provided on the left side shell wall of the pretreatment tank 2, and a drain pipe is provided at the bottom of the pretreatment tank 2.

[0030] The working principle of the plastic raw material processing equipment based on Embodiment 1 is as follows: When the plastic raw material is processed, the drive motor 7 is started first, and cleaning water is injected into the pretreatment tank 2 through the water inlet pipe. The operation of the drive motor 7 causes the rotating shaft to move, and the movement of the rotating shaft causes the mixing impeller 4 to rotate. The movement of the rotating shaft drives the adjusting member 53 in the filter assembly 5 to reciprocate back and forth through the linkage component. The movement of the adjusting member 53 causes the support member 54 set on it to move, and the support member 54 makes contact with the corrugated plate 52, thereby causing the screening plate 51 to vibrate up and down. Various plastic raw materials enter the pretreatment tank 2 through different feed ends set at the top of the pretreatment tank 2. When the raw materials enter the pretreatment tank 2, they fall onto the screening plate 51 in the filter assembly 5 under the action of the mixing impeller 4. With the presence of cleaning water in the pretreatment tank 2, the raw materials entering the pretreatment tank 2 are screened and mixed by the movement of the screening plate 51 and the action of the mixing impeller 4, thereby achieving the dust removal effect on the raw materials. After the raw material pretreatment is completed, turn off the drive motor 7 and open the drain pipe at the bottom of the pretreatment tank 2 to discharge the screened raw material along with the wastewater. After discharge, open the cabinet door and guide component 6 on the front shell wall of the pretreatment tank 2 to transport the raw material in the pretreatment tank 2 to the mixing equipment 3 through the guide component 6. After the raw material is transported, add the additive through the feed end at the top of the mixing equipment 3, and then use the agitator 32 to mix and stir it to complete the preparation of the plastic raw material. After the preparation is completed, it is discharged from the discharge pipe at the bottom.

Symmetrical support components 54 are provided at both ends of the top of the vertical bar. The end of the horizontal bar away from the vertical bar passes through the back shell wall of the pretreatment box 2. The support component 54 includes a support fixedly connected to the vertical bar, with rollers connected to the support via positioning pins. The rollers make rolling contact with the wave plate 52. The linkage assembly includes a fixed cylinder 8 sleeved on the rotating shaft. A U-shaped groove is provided on the peripheral wall of the fixed cylinder 8, with a movable frame 9 slidably connected in the U-shaped groove. The bottom end of the movable frame 9 is fixedly connected to a horizontal bar extending outside the pretreatment box 2.

[0033] In this embodiment, the chute and slider are configured to guide the longitudinal movement of the screening plate 51.

The mixing component 32 includes a mixing motor 321 connected to the top outer wall of the housing 31 by screws, and a mixing shaft 322 is provided at the output end of the mixing motor 321, with the bottom of the mixing shaft 322 extending into the interior of the housing 31. The material guide 6 includes a pipe 61, and a through groove is provided on the top shell wall of the pipe 61, in which a baffle 62 for blocking the flow of raw materials is inserted. A positioning bolt 63 for limiting and fixing is provided on the top of the baffle 62. A discharge port is provided on the right shell wall of the pretreatment box 2, and an inlet is provided on the top shell wall of the housing 31. The two ends of the pipe 61 are respectively fixedly connected to the discharge port and the inlet.
