Description

Technical Field

[0001] The utility model relates to the technical field of engineering plastic crushing, in particular to crushing equipment for engineering plastics. Background Art

[0002] With the development of industry, engineering plastics have also been widely used. However, engineering plastics are often discarded directly after use, which not only pollutes the environment, but also wastes resources and does not meet the requirements of the existing green economy. The existing way to recycle engineering plastics is mainly to crush them first and then carry out subsequent processing so that they can be fully utilized.

[0003] In the existing engineering plastic crushing process, although the impact force between the raw materials and the crusher and the inner wall of the crusher is not large, noise will still be generated. In addition, the vibration of the crusher during operation will also generate a lot of noise. When workers are operating, a lot of noise is very harmful to their physical and mental health.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] See also Figure 1-Figure 3The utility model discloses a crushing device for engineering plastics, including a frame 1, a spring shock absorber 2 is installed on the top of the frame 1, and a support beam 3 is installed on the top of the spring shock absorber 2, a crushing bin 4 is installed on the support beam 3, and a discharge bin 5 is installed at the bottom of the crushing bin 4, and a feeding bin 6 is installed on the top of the crushing bin 4, a crushing knife shaft 7 is installed in the crushing bin 4 through a bearing, a reduction motor 8 is installed on the support beam 3, and the output shaft end of the reduction motor 8 is transmission-connected to the crushing knife shaft 7, and a corrugated rubber sleeve 9 is connected to the bottom of the discharge bin 5, A screw conveyor 10 is connected via a corrugated rubber sleeve 9. After the material is put in, the crushing cutter shaft 7 is driven to rotate by a reduction motor 8, so as to cut and crush the material. During the crushing process, the microporous plate lining 13 and the glass wool sound-absorbing board 12 can effectively absorb and reduce the reflected sound waves in the crushing bin 4, thereby reducing noise pollution. At the same time, the spring shock absorber 2 below the crushing bin 4 can absorb the vibration and impact caused by the mechanical operation, thereby attenuating the noise caused by the mechanical vibration, and further protecting the surrounding working environment.

[0021] The crushing bin 4 , the discharging bin 5 and the feeding bin 6 all include an outer iron sheet 11 , a glass wool sound absorbing board 12 and a microporous plate lining 13 , and the glass wool sound absorbing board 12 and the microporous plate lining 13 are sequentially compounded on the outer iron sheet 11 .

[0022] Specifically, a control switch 14 is installed on the frame 1 , and the reduction motor 8 and the screw conveyor 10 are electrically connected to the control switch 14 , respectively.

[0023] In this embodiment, the control switch 14 is a common electrical component, and its main function is to control the start and stop of electrical equipment in the circuit.

[0024] Specifically, the crushing blade shafts 7 are provided in two groups, and are connected to each other through gear transmission.

[0025] In this embodiment, one crushing blade shaft 7 is driven to rotate by the reduction motor 8, and the other crushing blade shaft 7 is rotated in conjunction with the gear.

[0026] Specifically, comb plates 15 are installed on the front and rear inner walls of the crushing bin 4 , and the comb plates 15 and the crushing blade shaft 7 are interlaced with each other.

[0027] In this embodiment, the comb plate 15 is mainly used to prevent the material from being wrapped around the cutter shaft. After the cutter shaft squeezes and cuts the material, part of the material will flow into the discharge bin 5 due to the staggered engagement between the comb plate 15 and the cutter shaft.

[0028] Specifically, the screw conveyor 10 is fixed to the lower part of the frame 1 and is arranged in an inclined state.

[0029] In this embodiment, the screw conveyor 10 is a multifunctional conveying device, which is mainly used to continuously convey various bulk materials, such as granules, powders, blocks, etc. to a destination.

[0031] In this embodiment, when materials are put in, the bin cover 16 is pushed open by the materials. After the materials enter the feeding bin 6, the bin cover 16 is reset under the action of the tension spring 17, which can play a role in dust prevention and noise reduction.

[0032] When in use, after the material is put in, the reduction motor 8 drives the crushing blade shaft 7 to rotate, thereby cutting and crushing the material. During the crushing process, the cooperation of the microporous plate lining 13 and the glass wool sound-absorbing board 12 can effectively absorb and reduce the reflected sound waves in the crushing bin 4, thereby reducing noise pollution. At the same time, the spring shock absorber 2 under the crushing bin 4 can absorb the vibration and impact caused by the mechanical operation, thereby attenuating the noise caused by the mechanical vibration, further protecting the surrounding working environment, and the crushed material flows from the discharge bin 5 into the screw conveyor 10, and then the screw conveyor 10 transports the material to the next processing station.

[0033] In summary, after the materials are put into the crushing equipment for engineering plastics, the crushing blade shaft 7 is driven to rotate by the reduction motor 8 to cut and crush the materials. During the crushing process, the cooperation of the microporous plate lining 13 and the glass wool sound-absorbing board 12 can effectively absorb and reduce the reflected sound waves in the crushing bin 4, thereby reducing noise pollution. At the same time, the spring shock absorber 2 under the crushing bin 4 can absorb the vibration and impact caused by the mechanical operation, thereby attenuating the noise caused by the mechanical vibration, and further protecting the surrounding working environment.
