Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 6 As shown, the present invention provides a waste crushing device for PE packaging box production, comprising a box body 1, a feeding port 11 is provided at the top of the box body 1, a primary crushing chamber 12 is provided at the upper part of the inner wall of the box body 1, a secondary crushing chamber 13 is provided at the middle part of the inner wall of the box body 1, dust collecting chambers 14 are provided at both the front and rear sides of the secondary crushing chamber 13, and the box body 1 comprises a primary crushing mechanism 3 for primary crushing, a flow control mechanism 4 for controlling the flow rate, a secondary crushing mechanism 5 for secondary crushing, and a dust collecting and filtering mechanism 6 for dust collection;

[0034] A first motor 32 is arranged on the right side of the box body 1, and a pinion 33 is fixedly sleeved on the output shaft of the first motor 32, a first toothed disc 34 is meshedly mounted on the outer surface of the pinion 33, a second toothed disc 35 is meshedly mounted on the outer surface of the first toothed disc 34, and a rotating shaft of a crushing roller 36 is fixedly sleeved inside the first toothed disc 34 and the second toothed disc 35, and the crushing roller 36 is rotatably connected to the inner wall of the preliminary crushing chamber 12;

[0035] A second mounting frame 51 is provided on one side of the first motor 32, and a second motor 52 is symmetrically mounted on the top of the second mounting frame 51. A cutting shaft 53 is fixedly sleeved on the output shaft of the second motor 52. The cutting shaft 53 is rotatably connected to the inner wall of the secondary crushing chamber 13, and a plurality of arc-shaped knives 54 are fixedly connected to the outer surface of the cutting shaft 53.

[0036] In this embodiment, when waste is put into the preliminary crushing chamber 12 from the feed port 11 at the top of the box body 1, the waste will fall into the preliminary crushing chamber 12, and the first motor 32 is started, and its output shaft drives the pinion 33 to rotate, and the pinion 33 drives the first toothed disc 34 to rotate, and the first toothed disc 34 rotates while also driving the second toothed disc 35 to rotate, thereby driving the two crushing rollers 36 to rotate towards each other, and performing preliminary crushing operations such as squeezing and tearing on the waste falling into the preliminary crushing chamber 12, and preliminarily crushing larger pieces of waste into relatively smaller pieces;

[0037] After the waste material after the initial crushing enters the secondary crushing chamber 13, the second motor 52 is started, and the output shaft of the second motor 52 drives the cutting shaft 53 to rotate. The cutting shaft 53 drives a number of arc-shaped knives 54 to rotate at high speed, and the waste material that has been initially crushed is cut and crushed again, so as to further refine the waste particles, meet different subsequent processing requirements, and improve the crushing efficiency.

[0038] In a further embodiment, a transmission rod 41 is fixedly connected to the outer side of the second gear plate 35, and a linkage rod 42 is movably connected to the outer surface of the transmission rod 41. The top end of the linkage rod 42 is fixedly sleeved on the outer surface of the force-bearing rod 43. One end of the force-bearing rod 43 passes through the slide groove 112 and is fixedly connected to a baffle 44. The baffle 44 is slidably connected to the inner wall of the movable groove 111.

[0039] In this embodiment, when the second toothed disc 35 rotates, it can drive the transmission rod 41 to move synchronously. The transmission rod 41 drives the force-bearing rod 43 to move through the linkage rod 42, so that the baffle 44 can slide back and forth on the inner wall of the movable groove 111, thereby controlling the flow rate of the material from the feed port 11 to the preliminary crushing chamber 12, ensuring that the amount of material entering the preliminary crushing chamber 12 is at an appropriate level, which helps to improve the overall crushing efficiency and quality, and provides a guarantee for the stable operation of the entire device.

[0040] In a further embodiment, a small pulley 61 is fixedly sleeved on the outer surface of one end of the cutting shaft 53 close to the second motor 52, a belt 62 is meshedly installed on the outer surface of the small pulley 61, a large pulley 63 is meshedly installed on one end of the belt 62, a transmission shaft 64 is fixedly sleeved on the temporal part of the large pulley 63, one end of the transmission shaft 64 is rotatably connected to the inner wall of the dust collecting chamber 14, the other end of the transmission shaft 64 is rotatably connected to the inside of the filter plate 65, one end of the transmission shaft 64 close to the filter plate 65 is fixedly sleeved with an impeller 66, the impeller 66 is rotatably connected to the inner wall of the air outlet pipe 67, and the inner wall of the dust collecting chamber 14 is slidably connected to a dust collecting drawer 69.

[0041] The large pulley 63 is driven by the small pulley 61 to rotate through the belt 62, and the large pulley 63 drives the transmission shaft 64 to rotate. When the transmission shaft 64 rotates, it drives the impeller 66 to rotate on the inner wall of the air outlet pipe 67, so that the air flows, and the dust and other impurities generated in the crushing process are sucked into the dust collecting chamber 14, and then the dust and other impurities are retained in the dust collecting chamber 14 through the filter plate 65. The filtered gas is discharged from the air outlet pipe 67, and the dust retained in the dust collecting chamber 14 will naturally fall into the dust collecting drawer 69 under the action of gravity and the like. When the dust collecting drawer 69 is full of dust, the operator can easily draw it out for cleaning. This design can effectively collect dust, improve the efficiency and range of dust collection, enable more dust to be captured in time, reduce the possibility of dust escaping into the working environment, and better ensure the air quality in the workplace and the cleanliness of the equipment.

[0042] In a further embodiment, one end of the air outlet pipe 67 is fixedly connected to the side wall of the box body 1 , and the filter plate 65 is fixedly connected to the inner wall of the air outlet pipe 67 .

[0043] In this embodiment, when the dust suction airflow is discharged through the air outlet pipe 67, the filter plate 65 can fully exert its filtering effect. It can intercept the fine dust particles remaining in the airflow, prevent these dusts from being discharged to the outside of the equipment with the airflow, avoid polluting the external environment, and at the same time ensure that the discharged air is relatively clean and meets environmental protection requirements.

[0044] In a further embodiment, a plurality of dust suction holes 68 are formed on the inner wall of the dust collecting chamber 14 , and the dust suction holes 68 pass through the interior of the secondary crushing chamber 13 .

[0045] In this embodiment, the dust suction holes 68 allow dust to enter the dust collecting chamber 14 from the secondary crushing chamber 13 in an orderly manner, and the dust is collected and processed in the dust collecting chamber 14 through the dust collecting drawer 69, etc., thereby avoiding the accumulation of dust in the secondary crushing chamber 13, and reducing the frequency and difficulty of manually cleaning the dust in the secondary crushing chamber 13.

[0046] In a further embodiment, a material collecting box 7 is provided below the secondary crushing chamber 13 , and the material collecting box 7 is slidably connected to the lower part of the inner wall of the box body 1 .

[0047] In this embodiment, the PE packaging box waste particles after two crushings can naturally fall into the collecting box 7, avoiding the crushed materials from being scattered around in the box body 1, facilitating the subsequent unified processing of the materials, eliminating the need for frequent cleaning or transfer of materials, and reducing the frequency of manual operations.

[0048] In a further embodiment, a connecting frame 2 is fixedly connected to the right side of the box body 1 , and a second mounting frame 51 is fixedly mounted at the center of the top end of the connecting frame 2 .

[0049] In this embodiment, the second mounting bracket 51 is fixed to the top end of the connecting bracket 2, providing a clear mounting position for the second motor 52, so that the second motor 52 and the cutting shaft 53 and other components can be positioned and installed more easily.

[0050] In a further embodiment, the first motor 32 is fixedly mounted on the top of the first mounting frame 31 , the left end of the first mounting frame 31 is fixedly connected to the side wall of the box body 1 , and the bottom end of the first mounting frame 31 is fixedly connected to the top of the connecting frame 2 .

[0051] In this embodiment, the installer can first fix the first mounting frame 31 at the corresponding positions of the box body 1 and the connecting frame 2, and then install the first motor 32 to the top of the first mounting frame 31. The first mounting frame 31 provides sufficient supporting force for the first motor 32 to prevent the first motor 32 from shaking, shifting, etc. during operation, thereby ensuring that the first motor 32 is always in the correct working position.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
