Description

Technical Field

[0001] This utility model relates to the field of polystyrene production technology, specifically a polystyrene plastic pelletizer. Background Technology

[0002] Polystyrene is a colorless and transparent thermoplastic. It is a polymer compound formed by the free radical addition polymerization of styrene monomers. During its production process, it is pelletized.

[0003] In the prior art, such as the application with application number 202320092164.6, which discloses a polystyrene pelletizer, the surface of the blades after cutting and resetting can be effectively cleaned by a cleaning brush and a scraper, thereby removing the polystyrene strips adhering to the blades and ensuring the efficiency of polystyrene strip pelletizing.

[0004] However, in the existing technology, such as the polystyrene pelletizer mentioned in application number 202320092164.6, the shape of the plastic pellets produced by cutting is too uniform and cannot be adapted to different production needs. The design has shortcomings. At the same time, the cut plastic pellets are discharged directly without cooling, which can easily cause them to stick together during the discharge process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] To address the problems existing in the prior art, this embodiment provides the following technical solution: a polystyrene plastic pelletizer, comprising a pelletizer body 1 and a disassembly mechanism 3. The disassembly mechanism 3 is located on the upper exterior of the pelletizer body 1, facilitating the removal of the mold plate 31 from the interior of the pelletizer body 1, and can be replaced according to different production needs. Simultaneously, a dispersion mechanism 7 is provided, located on the lower interior of the pelletizer body 1, to facilitate the dispersion of the cut plastic pellets, effectively preventing the plastic pellets from sticking together during feeding.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, by setting the feed port 2 at the upper middle part of the pelletizer body 1, the polystyrene plastic solution to be cut can be poured into the interior of the pelletizer body 1. The polystyrene plastic solution will first enter the upper right side of the interior of the pelletizer body 1 and be located to the left of the push component 4 set on the upper right side of the interior of the pelletizer body 1. By setting the mold plate 31 on the upper left side of the pelletizer body 1, and the discharge holes 32 are arranged in an array inside the mold plate 31, the first electric push rod 42 can be opened. The first electric push rod 42 is of model HB-DJ801. The output end of the first electric push rod 42 can push the connected push plate 41 to move to the left. The push plate 41 will squeeze the polystyrene plastic solution, which will squeeze the polystyrene plastic solution through the interior of the discharge hole 32 and turn it into a long strip, which is convenient for the subsequent cutting of the polystyrene plastic solution.

[0029] A cutting blade 51 is provided on the left side of the mold plate 31. When cutting polystyrene plastic strips, the cutting blade 51 is prone to sticking. Therefore, an anti-sticking component 6 is provided on the left side of the cutting blade 51. The anti-sticking component 6 includes a sponge brush 61 located behind the right side of the cutting blade 51. The sponge brush 61 is installed at the output end of the second electric push rod 65, which is also model HB-DJ801. At the same time, a lubricant tank 63 is connected to the top of the sponge brush 61 through a connecting pipe 62. The lubricant tank 63 contains silicone-based lubricant. A valve 64 is provided at the upper end of the connecting pipe 62. When the valve 64 is opened, silicone-based lubricant can be introduced into the sponge brush 61 through the connecting pipe 62. The sponge brush 61 can absorb the silicone-based lubricant.

[0030] Simultaneously, before the cutting blade 51 cuts the polystyrene strip, it is mounted on the output shaft of the motor 52. A connecting block 53 is mounted on the upper side of the motor 52, and its upper end is slidably positioned inside the electromagnetic slide rail 54. By activating the controller of the electromagnetic slide rail 54, the connecting block 53 can slide left and right within it. The connection between the electromagnetic slide rail 54 and the connecting block 53 relies primarily on the combined effect of electromagnetic force and rolling friction. The movement of the connecting block 53 causes both the cutting blade 51 and the motor 52 to move, thus allowing the cutting blade 51 to move to the right. The blade is moved to the side until it is in contact with the sponge brush 61, and then the motor 52 is turned on. The motor 52 is model Z4-180-21. The motor 52 can make the cutting blade 51 rotate. The cutting blade 51 can rotate and come into contact with the sponge brush 61. The silicone-based lubricant absorbed inside the sponge brush 61 can be applied to the cutting blade 51. After the cutting blade 51 is applied, the second electric push rod 65 can be turned on to move the sponge brush 61 upward so that it does not affect the subsequent cutting of the polystyrene plastic strip by the cutting blade 51. At this time, the cutting blade 51 can effectively cut the polystyrene plastic strip extruded from the discharge hole 32.

[0031] like Figure 2 and Figure 3 As shown, after the plastic strip is cut, it falls downwards and passes over the sloping screen 71 at the bottom of the pelletizer body 1. A rotating plate 8 is set on the right side of the screen 71. The rotating plate 8 is fixed to the pelletizer body 1 by bolts. The rotating plate 8 can be opened by loosening the bolts to facilitate the output of plastic pellets. In addition, a fan 72 is set below the screen 71 and installed above the support plate 73. By turning on the fan 72, the fan 72 can blow air upwards to cool the rolling plastic pellets and prevent the material from sticking together.

[0032] like Figure 1 and Figure 5 As shown, a limiting frame 33 is symmetrically and tightly attached to the upper part of the mold plate 31. A locking block 34 is fixedly installed on the left side of the middle part of the limiting frame 33. The right side of the locking block 34 is engaged with the limiting block 35. The lower part of the limiting block 35 is fixedly connected to the pelletizer body 1. The locking block 34 can be pulled to the left to disengage it from the locked limiting block 35. At this time, the limiting frame 33 will also move along with the locking block 34 and can be separated from the attached mold plate 31. Then, the handle in the middle of the mold plate 31 can be pulled upward to remove the mold plate 31 from the inside of the pelletizer body 1 for replacement.

[0033] The working principle of this polystyrene plastic pelletizer is as follows: After the polystyrene plastic solution is poured into the pelletizer body 1, it is squeezed by the push component 4 and turned into a long strip through the discharge hole 32. Then, the long strip of polystyrene plastic is cut by the cutting component 5. Before cutting, the cutting blade 51 can be coated with a silicone-based lubricant to reduce the sticking phenomenon between the cutting blade 51 and the polystyrene plastic strip during subsequent cutting. The cut plastic pellets can be cooled and discharged by the dispersion mechanism 7 set at the bottom of the pelletizer body 1 to avoid the sticking phenomenon of the discharge. At the same time, the mold plate 31 is easy to disassemble, that is, it can be replaced according to production needs.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
