Description

Technical Field

[0001] The utility model relates to the technical field of plastic crushing, and in particular to a foam plastic crusher. Background Art

[0002] Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. They are polymer materials with plastic as the basic component and containing a large number of bubbles. They can also be said to be composite plastics with gas as filler. They have many excellent properties, such as light weight, high specific strength, ability to absorb impact loads, good heat insulation and sound insulation, etc. Therefore, they have been widely used in industry, agriculture, construction, transportation and other fields.

[0003] However, the existing foam plastic crusher cannot crush the foam plastic well. During the crushing process, the foam plastic is often not crushed properly and is of different sizes, which requires a second crushing, greatly reducing work efficiency and increasing the investment in manpower and material resources.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technology of a foam plastic crusher in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5As shown, the utility model provides a technical solution: a foam plastic crusher, comprising a housing 1, a first motor 5 and a second motor 6 are fixedly installed on the side wall of the housing 1, the output end of the first motor 5 is connected to the first bearing 12, the end of the first bearing 12 away from the first motor 5 is hinged to the inner side wall of the housing 1, the first bearing 12 is sequentially connected with the first crushing wheel 11, the second crushing wheel 10 and the third crushing wheel 9, the output end of the second motor 6 is connected to the second bearing 8, the outer surface of the second bearing 8 is surrounded by a crushing roller 7, and the end of the second bearing 8 away from the second motor 6 is hinged to the inner side wall of the housing 1. Auxiliary crushing plates 19 are respectively arranged on both sides of the crushing roller 7, and a reset spring 18 is fixedly installed on the side of the auxiliary crushing plate 19 away from the crushing roller 7, and the end of the reset spring 18 away from the auxiliary crushing plate 19 is welded to the inner side wall of the housing 1. A filter plate 3 is arranged directly below the crushing roller 7, and a collection chamber 17 is arranged below the filter plate 3. By starting the first motor 5 and the second motor 6, the crushing roller 7 rotates counterclockwise, the three crushing wheels rotate clockwise, the first crushing wheel 11 and the third crushing wheel 9 are equipped with multiple groups of cutting blades 22 tilted to the right, and the second crushing wheel 10 in the middle is equipped with multiple groups of fine blades 21 tilted to the left. When the crushing roller 7 rotates, due to the structural characteristics of the counterclockwise rotation and the inclined crushing blade head 20, the first crushing wheel 11 and the third crushing wheel 9 crush the plastic first, and then the second crushing wheel 10 crushes the incompletely crushed plastic for the second time, which greatly improves the quality of the plastic. The crushing efficiency of the crusher is improved, and the uneven crushing of foam plastics is avoided to a certain extent; in addition, through the arrangement of two sets of auxiliary crushing plates 19, the foam plastics are always in an environment of being squeezed and touched, thereby enhancing their force and forcing the foam plastics to always be located between the crushing roller 7 and the three sets of crushing wheels, thereby achieving continuous and efficient cutting and crushing of the foam plastics; at the same time, foam plastics that meet the crushing requirements can directly pass through the filter plate 3 into the collection chamber 19, and foam plastics that do not meet the crushing requirements will be crushed in a cycle until foam plastics that meet the crushing standards are obtained.

[0023] For details, please refer to Figure 1-Figure 3 As shown, a water tank 4 is installed on the top of the shell 1, and two groups of water outlets 13 are dug in the top of the shell 1 located below the water tank 4. The shell 1 and the water tank 4 are connected through the water outlets 13. Liquid storage chambers 14 are provided below the two groups of water outlets 13, and multiple groups of atomizing nozzles 15 are installed on the end surface of each group of liquid storage chambers 14. A feed port 2 is dug on the shell 1, and a baffle 16 is welded at the bottom end of the feed port 2. The baffle 16 is placed inside the shell 1 and above the auxiliary crushing plate 19.

[0024] In this embodiment, by setting up a water tank 4 and an atomizing nozzle 15, and the atomizing nozzle 15 is set on both sides of the grinder, when pouring foam plastic into the grinder, it can be directly sprayed to reduce dust, reduce the influence of static electricity, make it gather and precipitate, effectively avoid the foam plastic inside the crusher from flying around, and improve the crushing efficiency.

[0025] For details, please refer to Figure 4-Figure 5 As shown, a plurality of groups of crushing blades 20 are installed around the surface of the crushing roller 7. The crushing blade 20 is an inclined tool. The first crushing wheel 11 and the third crushing wheel 9 have exactly the same structure. Cutting blades 22 are installed on the circumference of the first crushing wheel 11 and the third crushing wheel 9, and a fine blade 21 is installed on the circumference of the second crushing wheel 10.

[0026] In this embodiment, the inclined cutter installed on the crushing roller 7 can roll the foam plastic that falls under the crushing roller 7 into the crushing roller 7 when the second motor 6 is started to drive the crushing roller 7 to rotate counterclockwise, making it convenient for the crushing roller 7 and the crushing wheel to cut and crush it. At the same time, the blades of different sizes and inclination directions cross-installed on the three groups of crushing wheels make the crushing of the foam plastic more uniform and thorough, thereby enhancing the practicality of the crusher to a certain extent.
