By starting the dust suction fan, the dust is allowed to enter the dust suction box through the dust suction pipe and be filtered by the dust collecting net. In order to ensure the filtering effect of the dust collecting net and avoid excessive dust accumulation on the surface, the rotating shaft can be rotated to drive the bottom turntable to rotate. After loosening the rotating shaft, the turntable is quickly reset under the action of the coil spring, and at the same time drives the flexible striking hammer to rotate and flexibly strike the dust collecting net 15, so that the dust accumulated on the surface falls down, and the dust falls from the ash falling port into the dust collecting drawer at the bottom. The dust collecting drawer can be pulled out from the frame later, and then the dust inside it is cleaned, which is convenient to use.

[0022] The present invention provides a plastic crushing and dust removal device, including a casing 101, a crushing roller 102 and a dust removal assembly 103, the dust removal assembly 103 including a flipping shell 104, a rotating plate 105, a rotating cylinder 106, a partition 107, a negative pressure component 108, a first filter 111 and a flipping component 116, the negative pressure component 108 including a connecting pipe 112, a collecting box 113, a second filter 114 and a fan 115, the flipping component 116 including a rotating shaft 118, flipping teeth 117, a gear 119 and a gear ring 120. It can be understood that the above scheme can be used to remove dust on the surface of crushed plastic particles, and can also be used to enhance the flipping effect of the plastic particles inside the flipping cavity 122.

[0023] According to this specific embodiment, the crushing roller 102 is rotatably mounted on the housing 101. A feed port is provided on the housing 101. Two crushing rollers 102 are provided. The plastic to be crushed is added to the clamping housing 101 through the feed port, and the two crushing rollers 102 are driven by an external motor to rotate towards each other, thereby crushing the plastic entering between the two crushing rollers 102.

[0024] The flip shell 104 is fixedly connected to the housing 101 and is located at the bottom of the housing 101 and is in communication with the housing 101. The rotating plate 105 is rotatably connected to the flip shell 104 and is located inside the flip shell 104. The rotating cylinder 106 is fixedly connected to the rotating plate 105 and is located on one side of the rotating plate 105. The partition 107 is fixedly connected to the rotating cylinder 106 and is arranged on the outside of the rotating cylinder 106. The rotating cylinder 106 has a through hole 109, which passes through the rotating cylinder 106. The negative pressure member 108 is provided On the flip shell 104, the negative pressure member 108 is used to extract the air inside the rotating cylinder 106; a rotating motor 110 is installed on one side of the flip shell 104, and the output end of the rotating motor 110 passes through the flip shell 104 and is connected to the rotating plate 105. A plurality of partitions 107 are provided, and a flip chamber 122 is formed between two adjacent partitions 107. A discharge port is provided at the bottom of the flip shell 104, and a conveyor belt 123 is provided below the discharge port. The conveyor belt 123 is used to transport the crushed plastic to the next process. The interior of the rotating cylinder 106 is hollow, and through the The negative pressure member 108 draws out the air inside the rotating cylinder 106, and then the through hole 109 draws in air, thereby drawing out the air inside the flip chamber 122 and the housing 101, forming a negative pressure inside the housing 101, and preventing the dust generated when the plastic is crushed from escaping into the air; at the same time, the crushed plastic falls into the flip shell 104 and falls between the flip chamber 122, and the rotating plate 105 is driven to rotate by the rotating motor 110, and then the rotating plate 105 drives the rotating cylinder 106 and the partition 107 to rotate, thereby driving the inside of the flip chamber 122. The plastic rotates. During the process of the flipping cavity 122 driving the plastic particles to rotate, the plastic particles flip in the flipping cavity 122 to prevent the accumulation of plastic particles from affecting the dust removal effect. Finally, air and dust attached to the plastic particles are inhaled through the through hole 109. When the plastic particles rotate to the discharge port at the bottom of the flipping shell 104, the plastic particles fall onto the conveyor belt 123. The conveyor belt 123 transports the plastic particles to the next process, thereby removing the dust on the crushed plastic particles and avoiding the problem of a large amount of dust adhering to the crushed plastic particles, which pollutes the environment and affects subsequent processing.

[0025] Secondly, the first filter 111 is fixedly connected to the rotating cylinder 106 and is located on the side of the rotating cylinder 106 close to the through hole 109; there are multiple first filters 111, and each of the flipping chambers 122 is provided with a first filter 111. The through hole 109 is blocked by the first filter 111, so that air and dust can enter the rotating cylinder 106, thereby preventing plastic particles from entering the rotating cylinder 106 through the through hole 109 or plastic particles from clogging the through hole 109.

[0026] At the same time, the collection box 113 is fixedly connected to the flip shell 104 and is located on one side of the flip shell 104; the second filter 114 is fixedly connected to the collection box 113 and is located inside the collection box 113; the two ends of the connecting pipe 112 are respectively connected to the rotating cylinder 106 and the collection box 113, and the connecting pipe 112 is arranged on the collection box 113; the fan 115 is fixedly connected to the collection box 113 and is connected to the collection box 113; the connecting pipe 112 is connected to the rotating cylinder 106 and the collection box 113. The head is connected to the rotating cylinder 106, so as to avoid interference between the rotating cylinder 106 and the connecting pipe 112. The air inside the collecting box 113, the connecting pipe 112 and the rotating cylinder 106 is extracted by the fan 115, so that the through hole 109 on the rotating cylinder 106 can inhale air and dust. After the dust enters the collecting box 113, the dust is filtered by the second filter 114, so that the dust remains in the collecting box 113, and the air is discharged through the fan 115.

[0027] In addition, the flipping member 116 includes a rotating shaft 118 and a flipping tooth 117. The rotating shaft 118 is rotatably connected to the rotating plate 105 and is located on the side of the rotating plate 105 close to the rotating cylinder 106; the flipping tooth 117 is fixedly connected to the rotating shaft 118 and is arranged on the rotating shaft 118.

[0028] Finally, the gear 119 is fixedly connected to the rotating shaft 118 and is located on one side of the rotating shaft 118 ; the gear ring 120 is fixedly connected to the flip shell 104 and is located inside the flip shell 104 and meshes with the gear 119 .

[0029] The number of the gears 119 is consistent with the number of the rotating shafts 118. When the rotating plate 105 rotates, it also drives the gears 119 to rotate, causing the gears 119 to perform circular motion. Since the gears 119 are engaged with the gear ring 120, the gears 119 rotate while performing circular motion, thereby driving the corresponding rotating shafts 118 to rotate. The rotating shafts 118 drive the flipping teeth 117 to rotate, so that the flipping teeth 117 flip the plastic particles inside the flipping chamber 122, further improving the flipping effect of the crushed plastic particles.

[0030] When using the plastic crushing and dust removal device of this embodiment, the plastic to be crushed is put into the housing 101 through the feed port, and then the external motor is started to drive the two crushing rollers 102 to rotate in opposite directions to crush the plastic. The crushed plastic particles then fall into the flip shell 104 located at the bottom of the housing 101 and are received by the flip chamber 122. At the same time, the rotating motor 110 starts working, and its output end drives the rotating plate 105 to rotate in the flip shell 104. The rotating plate 105 does not rotate. The rotating cylinder 106 and the partition 107 are not only rotated by themselves, but also driven to rotate together, thereby driving the plastic particles in the flipping chamber 122 to rotate and flip. In this process, the flipping teeth 117, driven by the rotating shaft 118, flip the plastic particles in the flipping chamber 122 more finely, ensuring the full dispersion and uniform flipping of the plastic particles, thereby greatly improving the dust removal effect. In the process of crushing the plastic, the fan 115 extracts the air inside the rotating cylinder 106 through the connecting pipe 112. Air is drawn into the rotating cylinder 106 and negative pressure is formed at the through hole 109 of the rotating cylinder 106, so that the air in the tumbling chamber 122 and the interior of the housing 101 (including the air carrying dust) is sucked into the rotating cylinder 106 and is preliminarily filtered through the first filter 111 to prevent plastic particles from entering the rotating cylinder 106 or clogging the through hole 109. Subsequently, the dust-laden air enters the collection box 113 and is finely filtered by the second filter 114, so that the dust is effectively trapped in the collection box 113. The clean air is discharged through the fan 115; after the plastic particles are fully turned and dusted in the turning chamber 122, they gradually move to the discharge port at the bottom of the turning shell 104. At this time, the plastic particles fall on the conveyor belt 123, which transports them to the next process for further processing, effectively preventing the dust generated during the crushing process from escaping into the air, and removing dust from the crushed plastic particles, thereby protecting the operating environment and avoiding environmental pollution and quality problems in subsequent processing.

[0031] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
