Description

Technical Field

[0001] This utility model relates to a crushing device, and more particularly to a multi-stage crushing device for resin preforms. Background Technology

[0002] Resin materials are high molecular weight compounds extracted from plants and used to make various substances. Polyester resin is a general term for high molecular weight compounds formed by the condensation polymerization of diols or diacids, or polyols and polyacids. This type of adhesive has the characteristics of low viscosity, easy wetting, and good processability. The cured adhesive layer has high hardness, good transparency, and high gloss. It can also be cured quickly under pressure at room temperature and has good heat resistance and excellent electrical properties.

[0003] In the resin production process, polyester resin needs to be crushed into granules for further processing. However, existing crushing devices usually only have a single crushing function, which reduces the practicality of the crusher. In addition, the resin after the first crushing may still contain lumps of resin, which need to be put back into the crusher for secondary crushing, making the process quite complicated.

[0004] Therefore, it is necessary to design a multi-stage crushing device for resin preforms. Utility Model Content

[0005] In order to overcome the shortcomings of existing crushing devices with limited functionality, the technical problem of this utility model is to provide a multi-stage crushing device for resin preforms.

[0006] The technical implementation scheme of this utility model is as follows: A multi-stage crushing device for resin preforms includes a primary crushing box, a feeding frame, a fixed rod, a stirring rod, a fixed frame, a first motor, an extrusion cylinder, a filter screen, a crushing blade, a first track, a conveyor belt, and a secondary crushing mechanism. The feeding frame is fixedly connected to the top of the primary crushing box. The fixed rod is rotatably connected to the upper part of the primary crushing box. Several stirring rods are fixedly connected to the upper edge of the fixed rod circumferentially. The fixed frame is fixedly connected to the right side of the primary crushing box.

The conveyor belt 11 is located directly below the filter screen 701. The secondary crushing device is provided on the right side of the conveyor belt 11.

[0020] like Figure 1 , Figure 2 and Figure 4As shown, the secondary crushing mechanism includes a feeding plate 12, a secondary crushing box 13, a spiral pressure rod 14, a first gear 15, a second gear 16, a second motor 17, a second track 18, and a discharge port 19. The secondary crushing box 13 is fixedly connected to the lower right of the primary crushing box 1. The feeding plate 12 is located on the upper left side of the secondary crushing box 13. The feeding plate 12 is aligned with the right end of the conveyor belt 11. Two spiral pressure rods 14 are rotatably connected inside the secondary crushing box 13. The rear end of the rightmost spiral pressure rod 14 is fixedly connected to the first gear 15, and the rear end of the other spiral pressure rod 14 is fixedly connected to the second gear 16. The second gear 16 meshes with the first gear 15. The second motor 17 is placed on the rear side of the secondary crushing box 13. The output end of the second motor 17 is connected to the rightmost spiral pressure rod 14. The rightmost spiral pressure rod 14 is connected to the conveyor belt 11 by the second track 18. The discharge port 19 is located on the front side of the secondary crushing box 13.

[0021] like Figure 1 As shown, it also includes a dustproof enclosure 101, and the top of the secondary crushing device is covered with a dustproof enclosure 101.

[0022] like Figure 1 and Figure 2 As shown, it also includes an electromagnetic sticker 10. The electromagnetic sticker 10 is fixed to the lower part of the fixing frame 5 and is located on the upper right side of the conveyor belt 11.

[0023] like Figure 1 As shown, it also includes a glass plate 20, and the dustproof enclosure 101 has a glass plate 20 on the right side.

[0024] This equipment can be used when polyester resin needs to be crushed into granules. First, the operator needs to turn on the first motor 6. The first motor 6 drives the fixed rod 3 to rotate, and at the same time drives multiple stirring rods 4 to rotate. The crushing blade 8 connected to the first motor 6 through the first track 9 will also start to rotate. Then, the operator pours the polyester resin from the upper feed box 2 into the primary crushing box 1. The rotation of the stirring rods 4 can prevent the polyester resin from clogging the feed box 2 after it is poured in. Then, the polyester resin will fall into the extrusion cylinder 7 and be initially crushed by the rotating crushing blade 8 until the polyester resin is crushed into granules that can pass through the lower filter screen 701, and then it will fall onto the lower conveyor belt 11.

[0025] Next, the operator needs to turn on the second motor 17. The second motor 17 drives the first gear 15 and the meshing second gear 16 to operate simultaneously. The spiral pressure rod 14 and the conveyor belt 11 also start working. The polyester resin that falls onto the conveyor belt 11 will move with the conveyor belt 11 to the bottom of the electromagnetic sticker 10. The magnetic impurities in the polyester resin after primary crushing will be attracted by the electromagnetic sticker 10, thereby effectively removing the magnetic impurities. Then, the polyester resin will come to the secondary crushing mechanism. First, the polyester resin will enter the secondary crushing box 13 through the feeding plate 12, and then be further crushed by the spiral pressure rod 14. Finally, it will flow out from the discharge port 19. At this time, the operator can use a container to collect it. Thus, one round of polyester resin crushing process is completed. Repeating the above steps can continuously crush polyester resin.

[0026] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
