Description

Technical Field

[0001] This utility model relates to a tableting device for preparing plastic powder. Background Technology

[0002] Plastic powder is a high molecular compound formed by the polymerization of monomer raw materials through synthesis or condensation reaction. It is mainly composed of synthetic resin and additives such as fillers and plasticizers. The main process of producing plastic powder by crushing is as follows: first, the raw materials are proportioned, then the mixture is extruded to obtain plastic granules, and then the granules are pressed and crushed to obtain plastic powder. Pressing is a process of converting plastic granules into sheets through physical action.

Therefore, the processing steps are relatively complicated, resulting in low processing efficiency and high labor costs. In addition, plastic fragments generated during the tableting process are mixed in with the plastic sheets, and subsequent screening equipment is needed to separate the plastic fragments, which is time-consuming and labor-intensive and needs further improvement.

[0024] The power assembly includes four guide pillars 14 that are vertically inserted and symmetrically arranged in pairs in the base block 21, a drive plate 15 that is horizontally fixed between the lower ends of the four guide pillars 14 and between the two support blocks 22, and a lifting cylinder 16 fixed in the machine base 1 and located below the notch 101. The upper end of each guide pillar 14 is fixed to the bottom of the lifting plate 6, and the telescopic end of the lifting cylinder 16 passes vertically upward through the bottom of the notch 101 and is fixed on the drive plate 15.

[0025] The bottom of the top block 31 is also fixed with a horizontally arranged support plate 33 located above the pressure plate 5. The upper end of each pressing column 9 is fixed on the support plate 33. The telescopic end of the pressing cylinder 4 passes vertically downward through the top block 31 and the support plate 33 and is fixed on the pressure plate 5.

[0026] Multiple parallel dividing strips 124 are fixed between the inner walls of the front and rear sides of the storage frame 121, arranged in parallel from left to right. The multiple dividing strips 124 divide the interior of the storage frame 121 into multiple partition cavities 125 arranged in parallel from left to right. The number of partition cavities 125 is one more than the number of dividing strips 124.

[0027] Working principle: A certain amount of plastic extrusion granules are poured into the storage frame 121 and evenly distributed in each partition cavity 125; the telescopic end of the lifting cylinder 16 in the drive power assembly extends outward to drive the lifting plate 6 to move upward with the help of four guide pillars 14. Since the position of each upper top pillar 11 is fixed, and in the initial state, the second protrusion 111 on each upper top pillar 11 is filled with a corresponding extrusion sleeve 10, and the end of each second protrusion 111 is flush with the upper opening of the corresponding extrusion sleeve 10, when the lifting plate 6 moves upward, the end of each second protrusion 111 will retract into the interior of the corresponding extrusion sleeve 10 and form a columnar cavity inside the upper end of each extrusion sleeve 10.

[0028] Next, the telescopic end of the transfer cylinder 122 in the drive transfer mechanism 12 extends outward to drive the storage frame 121 to move to the right, thereby driving the plastic extrusion particles to move synchronously. When each partition cavity 125 is above the corresponding extrusion sleeves 10, the plastic extrusion particles in each partition cavity 125 will automatically fall into the columnar cavity generated in the extrusion sleeve 10 below it. Then, the telescopic end of the drive transfer cylinder 122 retracts inward to drive the storage frame 121 to move to the left for reset. Since the outer wall of the bottom opening of the storage frame 121 slides against the top outer wall of the lifting plate 6 or the platform 7, the excess plastic extrusion particles that have not entered the columnar cavity and remain on the top of the platform 7 will be pulled back to the original position by the storage frame 121 to the left, so that there are no plastic extrusion particles remaining on the top of the platform 7.

[0029] Next, the telescopic end of the pressing cylinder 4 in the pressing mechanism extends outward to drive each pressing column 9 to move vertically downward with the help of the pressure plate 5, so that the first protrusion 91 on each pressing column 9 is inserted into the upper opening of the corresponding extrusion sleeve 10, thereby squeezing the plastic extrusion granules located in the columnar cavity and pressing the plastic extrusion granules into a sheet shape; then the telescopic end of the pressing cylinder 4 retracts inward to drive each pressing column 9 away from the upper opening of the corresponding extrusion sleeve 10 in the same way.

[0030] Then, the telescopic end of the lifting cylinder 16 is driven to retract inward to move the lifting plate 6 downward in the same way, so that the second protrusion 111 on each upper top column 11 fills the corresponding extrusion sleeve 10 again to eliminate each columnar cavity, until the end of each second protrusion 111 is flush with the upper opening of the corresponding extrusion sleeve 10, so that the plastic sheet originally located in each columnar cavity flows out onto the top outer wall of the platform 7.

[0031] Then, the telescopic end of the transfer cylinder 122 is extended outward to drive the storage frame 121 to move to the right in the same way. Since the U-shaped pusher 123 is fixed on the right side of the storage frame 121 and its opening side is set to the right, and since the lower outer wall of the U-shaped pusher 123 slides against the top outer wall of the lifting plate 6 or the platform 7, and the front and rear width of the U-shaped pusher 123 is matched with the front and rear limit positions of the distribution area of ​​the multiple extrusion sleeves 10, when the storage frame 121 moves to the right, the U-shaped pusher 123 will move synchronously. As a result, the U-shaped pusher 123 will include all the plastic sheets that have flowed onto the top outer wall of the platform 7 during the rightward movement and push them to the right until the U-shaped pusher 123 is completely moved above the screen plate 1311, and then the plastic sheets will slide down to the top of the screen plate 1311.

[0032] During the above process, the telescopic end of the lifting cylinder 16 needs to be driven to extend outward again to drive the lifting plate 6 to move upward in the same way, so that the upper end of each extrusion sleeve 10 forms a columnar cavity again; and the plastic extruded particles located in each partition cavity 125 will move to the right again with the storage frame 121 and re-enter each columnar cavity, so that the feeding of plastic extruded particles can be completed at the same time as the plastic sheet is discharged, thus forming a cycle.

[0033] The plastic sheet moved to the top of the screen plate 1311 will slide down the slope of the screen plate 1311 into the first discharge hopper 131, and enter the guide flat pipe 133 through the first discharge flat pipe 132. Since there will inevitably be broken plastic powder in the plastic sheet, this plastic powder will enter the second discharge hopper 135 through multiple discharge slots 1312 during the movement of the top of the screen plate 1311, and then be discharged out through the second discharge flat pipe 136. In this way, the plastic powder and plastic sheet are collected separately.

[0034] This invention can automatically complete the feeding of plastic granules and the discharging of plastic sheets without manual intervention, thereby effectively simplifying the processing steps, greatly improving processing efficiency and significantly reducing labor costs. In addition, it can automatically separate the plastic fragments generated during the discharging process of the plastic sheets, thus achieving the effect of saving time and labor.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
