Description

Technical Field

[0001] The invention relates to the field of plastic production equipment, in particular to a plastic crusher. Background Art

[0002] Plastics are macromolecules that are polymerized from monomers through addition polymerization or condensation polymerization. They have a medium resistance to deformation, between that of fibers and rubbers. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] The main component of plastic is resin. Resin refers to a high molecular compound that has not been mixed with various additives. The term resin was originally derived from the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastic are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or little additives, such as plexiglass and polystyrene.

[0004] At present, a Chinese patent with publication number CN106696130A discloses a crushing device for processing waste plastic bottles, which includes a crushing box and a feed bin. A feed port is provided on the top surface of the crushing box, a discharge port is provided on the bottom surface of the crushing box, fixed plug plates are symmetrically distributed on the bottom surface of the feed bin, a card slot is provided on the top surface of the crushing box, the card slot is located on both sides of the feed port, the card slot is connected to the fixed plug plate, a feed funnel is provided at the center of the feed bin, the feed funnel is located in the feed port, a crushing mechanism is provided in the crushing box, adjacent crushing mechanisms rotate towards each other, and I-shaped brackets are symmetrically distributed on the bottom surface of the crushing box, a material receiving box is provided between the I-shaped brackets, and the material receiving box is located below the discharge port.

[0005] Although this crushing device for processing waste plastic bottles can quickly process waste plastic bottles and press the waste plastic bottles into a deflated shape, it has high work efficiency, reduces manual labor intensity, has flexible overall connection, is easy to disassemble and assemble, and is highly practical, but the shape is not complete during the extrusion process and is not easy to pack and process. Summary of the invention

[0006] The object of the present invention is to provide a plastic crusher, which has the advantages of being able to effectively crush plastic into shape and being easy to pack the entire device without causing scattering problems.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A plastic crusher comprises a frame, on which a crushing device is also provided, wherein the crushing device comprises a placement groove provided on the frame, a downward pressure cylinder provided on the top of the frame, a downward pressure plate provided at the outlet of the downward pressure cylinder, a heating wire wrapped around the outer wall of the placement groove, a bracket provided above the downward pressure plate, auxiliary cylinders provided on both sides of the bracket, and a cutting plate perpendicular to the downward pressure plate provided at the outlet of the auxiliary cylinder.

[0009] By adopting the above technical solution, the provided pressing device can effectively press and shape the plastic in the placement groove. The plastic can be softened by the action of the heating wire, which is convenient for overall pressing and compacting. At the same time, the provided two side cutting plates can assist the entire plastic to form a more regular shape.

[0010] Further configuration: a shaping device is also provided on the rolling device, and the shaping device includes a placing plate located on one side of the lower pressure plate and fixed on the bracket, a rotating roller located on the placing plate, a plastic film reel mounted on the rotating roller, and a hook block provided at the bottom of the cutting plate.

[0011] By adopting the above technical scheme, the provided shaping device can effectively wrap the plastic film around the lower pressing plates on both sides, and pull it as the lower pressing plates move downward. When the plastic is put in for heating and softening when it reaches the bottom, the extruded plastic film will adhere to the formed plastic block, reducing scattering and the like, and effectively ensuring the overall forming state.

[0012] Further configuration: auxiliary devices are also provided on both sides of the lower pressure plate, and the auxiliary devices include blowers located on both sides of the frame, a blowing hole provided on the side of the cutting plate close to the placement groove, and a ventilation pipe located at the blower outlet and connected to the blowing hole of the cutting plate.

[0013] By adopting the above technical scheme, the auxiliary device can effectively ensure that the plastic film will not stick to the cutting board. At the same time, the hair dryer can effectively separate the plastic film from the surface of the cutting board, so as to ensure that it sticks to the entire plastic block and achieve the purpose of molding. At the same time, when necessary, a blower with integrated blowing and suction can be used to effectively adsorb the plastic film on the surface of the cutting board during the downward pressure process, and blow it out when it needs to be wrapped.

[0014] It is further provided that: a sealing cover which is threadedly connected to the rotating roller is also provided at the top of the rotating roller.

[0015] By adopting the above technical solution, the provided cover can effectively prevent the entire plastic film roll from falling, thereby ensuring that it can be pulled out normally.

[0016] It is further provided that: sliding grooves for supplying cutting boards to pass through are also provided on both sides of the placement groove.

[0017] By adopting the above technical solution, the provided slide groove can facilitate the passage of the entire cutting board and will not deviate to other positions at the specified position.

[0018] It is further configured that a shearing device is also provided in the lower pressing plate, and the shearing device comprises a pushing cylinder provided in the lower pressing plate, openings provided on both sides of the lower pressing plate, and a cutter provided at an outlet of the pushing cylinder.

[0019] By adopting the above technical solution, the provided shearing device can effectively cut the plastic film, thereby assisting the plastic film in wrapping the plastic blocks on both sides, thereby ensuring the overall operation.

[0020] Further configuration: a rotating hand wheel is also provided on the sealing cover.

[0021] By adopting the above technical solution, the rotating hand wheel is provided to facilitate the retraction and release of the plastic film roll, thereby making it convenient for the user to hang the plastic film on the hook block.

[0022] In summary, the present invention has the following beneficial effects: it can effectively extrude and mold plastics, effectively soften the plastics with the assistance of heating wires, and facilitate the overall bonding of the plastics together; at the same time, the provided plastic film can wrap both sides of the plastic block, facilitating the molding and extrusion of the entire plastic block, and transporting it, reducing the possibility of scattering.

The rolling device 2 includes a placement groove 21 provided on the frame 1, a downward pressure cylinder 22 is provided at the top of the frame 1, and a lower pressing plate 23 is provided at the outlet of the downward pressure cylinder 22. At the same time, a heating wire 24 is wrapped around the outer wall of the placement groove 21 for heating and softening the plastic in the placement groove 21. A bracket 25 is provided above the lower pressing plate 23, and auxiliary cylinders 26 are provided on both sides of the bracket 25. A cutting plate 27 perpendicular to the lower pressing plate 23 is provided at the outlet of the auxiliary cylinder 26. A slide 6 for supplying the cutting plate 27 is also provided on both sides of the placement groove 21. A shearing device 7 is also provided in the lower pressing plate 23, and the shearing device 7 includes a push cylinder 71 provided in the lower pressing plate 23, an opening 72 provided on both sides of the lower pressing plate 23, and a cutter 73 provided at the outlet of the push cylinder 71.

[0029] The rolling device 2 is also provided with a shaping device 3, which includes a placement plate 31 located on one side of the lower pressing plate 23 and fixed on the bracket 25, a rotating roller 32 is provided on the placement plate 31, a plastic film roll 33 is sleeved on the rotating roller 32, and a hook block 34 is provided at the bottom of the cutting plate 27 for hooking the plastic film. A sealing cover 5 threadedly connected to the rotating roller 32 is also provided at the top of the rotating roller 32, and a rotating hand wheel 8 is also provided on the sealing cover 5. Auxiliary devices 4 are also provided on both sides of the lower pressing plate 23, and the auxiliary devices 4 include blowers 41 located on both sides of the frame 1, a blowing hole 42 located on one side of the cutting plate 27 close to the placement groove 21, and a vent 43 located at the outlet of the blower 41 and connected to the blowing hole 42 of the cutting plate 27, which can effectively reduce the occurrence of plastic film attached to the cutting plate 27.

[0030] Its main working principle is as follows: during use, the plastic is placed in the placement groove 21, and then the plastic film roll 33 is put on the rotating roller 32, and the cover 5 is screwed on to prevent the plastic film roll 33 from falling, and the plastic film on the plastic film roll 33 is pulled down to the hook block 34 of the cutting plate 27. When extruding, the auxiliary cylinder 26 drives the cutting plate 27 downward and is fixed in the slide groove 6. At this time, the plastic film is also pulled down, and the downward pressure cylinder 22 drives the downward pressure plate 23 to extrude the plastic. At the same time, under the action of the heating wire 24, the plastic softens to a certain extent for easy extrusion. At this time, when it is extruded to a certain extent, the plastic block forms a certain shape. At this time, since the plastic film on the surface of the cutting plate 27 contacts the plastic block, the hair dryer 41 is started to blow the plastic film onto the plastic block. With the action of the heating wire 24, the plastic film sticks to the plastic block. The relative shape of the entire plastic block is relatively fixed, which is convenient for overall transportation and reduces the occurrence of scattering.
