[0003] For example, a pulverizing device for processing plastic particles is disclosed in the announcement number "CN212498507U". The pulverizing device for processing plastic particles pulverizes plastic by squeezing with pulverizing rollers. However, during the plastic pulverizing process, some plastics are pulled against each other by the pulverizing rollers, and it is easy for the plastics to stick to the pulverizing rollers. With long-term use, more plastics stick to the pulverizing rollers, which can easily affect the normal pulverizing effect of the pulverizing rollers and require staff to clean them.

When the scraper is in a state perpendicular to the crushing roller, as the crushing roller slowly rotates, the teeth of the crushing roller abut against the scraper. As the crushing roller rotates, the teeth of the crushing roller and the scraper are relatively displaced, so that the scraper can clean the plastic stuck to the crushing roller. As the crushing roller continues to rotate, the teeth of the crushing roller abut against the scraper. Since the scraper cannot continue to deform, it can push the scraper and the scraper, so that the disc rotates a certain angle.

Under the action of the spring piece 1, the auxiliary plate is in a position hinged with the scraper, so that the auxiliary plate swings to the side close to the scraper, and the auxiliary plate fits with the teeth of the crushing roller away from the scraper.

[0012] Compared with the prior art, the present invention provides a centralized crushing device for plastic particle processing, which has the following beneficial effects: 1. The centralized crushing equipment for plastic particle processing has a cleaning part and a crushing mechanism. As the crushing roller rotates, when the crushing roller rotates to collide with the scraper, the teeth of the crushing roller and the scraper are relatively displaced, so that the scraper can clean the plastic stuck to the crushing roller, and at the same time, the scraper can clean the surface of the crushing roller, without manual operation by the staff, and will not affect the normal work of the crushing roller, and is easy to use.

Only when the scraper blade cannot be deformed can the disc be pushed to rotate, ensuring that the scraper blade can fit well with the teeth of the crushing roller to improve the cleaning effect. When the disc rotates, the active resistance piece on the surface of the connecting ring is deformed by resistance, and the active resistance piece moves to between the next group of driven matching pieces to achieve stability. The disc can only rotate when it is subjected to a certain degree of external force, and the rotation angle is certain, so as to avoid the disc from rotating accidentally, resulting in the scraper and the crushing roller teeth not matching when the teeth of the subsequent crushing roller rotate, affecting the normal cleaning effect.

[0015] 4. The centralized crushing equipment for processing plastic particles has a scraper and a limit block. The limit block can limit the scraper so that the scraper cannot be separated from the scraper. When the teeth of the crushing roller contact the scraper, the scraper deforms to a certain extent, so that the scraper can better maintain contact with the teeth, thereby improving the effect of subsequent cleaning.

DETAILED DESCRIPTION

[0018] like Figure 1-Figure 10 As shown, the present invention provides a technical solution: a centralized crushing device for processing plastic particles, including a body 1, a fine material discharge port 6 is opened at the bottom of the body 1, and a coarse material discharge port 7 is opened on the left side of the body 1 to distinguish the crushed plastic particles, a crushing mechanism and a screening mechanism are arranged on the surface and inside of the body 1, the crushing mechanism is composed of a driving motor 11 and a crushing roller 12, and a cleaning part 2 for cleaning the crushing roller 12 and an auxiliary component 3 for cooperating with the cleaning part 2 are arranged inside the body 1.

[0019] like Figure 5-7As shown, in this embodiment, the cleaning part 2 includes a fixed rod 21, which is fixed on the inner wall of the body 1, and the fixed rod 21 penetrates the disc 22 and is rotatably connected to the disc 22. A scraper 23 is hinged on the surface of the disc 22, and a groove is provided at the end of the scraper 23 away from the disc 22. The inner side of the groove of the side of the scraper 23 away from the disc 22 is penetrated by a scraper 24, and the ends of both ends of the scraper 24 are provided with limiting blocks 25. The scraper 24 is made of iron, has a certain elasticity, and can be deformed to a certain extent. The limiting blocks 25 can limit the scraper 24 so that the scraper 24 cannot be separated from the scraper 23. When the teeth of the crushing roller 12 abut against the scraper 24, the abutting scraper 24 is deformed to a certain extent, so that the scraper 24 can better maintain contact with the teeth, thereby improving the effect of subsequent cleaning. A fixed block 26 is fixed on the surface of the disc 22, and the scraper 23 is limited by the fixed block 26. When the scraper 23 is in a state perpendicular to the pulverizing roller 12, as the pulverizing roller 12 slowly rotates, the teeth of the pulverizing roller 12 abut against the scraper 24. As the pulverizing roller 12 rotates, the teeth of the pulverizing roller 12 and the scraper 24 are relatively displaced, so that the scraper 24 cleans the plastic stuck to the pulverizing roller 12. As the pulverizing roller 12 continues to rotate, the teeth of the pulverizing roller 12 abut against the scraper 24. Since the scraper 24 cannot continue to deform, it can push the scraper 24 and the scraper 23, so that the disc 22 rotates a certain angle.

[0020] In this embodiment, the auxiliary component 3 includes a fixed plate 31, which is penetrated by the fixed rod 21 and fixedly connected to the fixed rod 21, a friction ring 32 is fixed on the side of the fixed plate 31 close to the disc 22, the scraper 23 is penetrated by the auxiliary plate 33 and is hinged to the auxiliary plate 33, a spring piece 34 is fixed on the surface of the auxiliary plate 33, the end of the spring piece 34 away from the auxiliary plate 33 is fixed to one side of the scraper 23, a push rod 35 is slidably installed on the other side of the scraper 23, a groove is also provided on the side of the auxiliary plate 33 away from the scraper 23, two groups of scrapers 24 and limit blocks 25 are provided, one group of scrapers 24 and limit blocks 25 are provided on the scraper 23, and the other group of scrapers 24 and limit blocks 25 are provided on the auxiliary plate 33, the surface of the friction ring 32 is provided with an embedded groove, and the friction ring 3 2 can resist the push rod 35, so that the push rod 35 can resist between the scraper 23 and the auxiliary plate 33, so that the auxiliary plate 33 and the scraper 23 are in an open state. When the scraper 23 rotates to a state perpendicular to the crushing roller 12, the push rod 35 moves to the embedded groove opened on the surface of the resistance ring 32, and the resistance ring 32 can no longer apply pressure to the push rod 35. Under the action of the spring piece 1 34, the auxiliary plate 33 is in a position hinged with the scraper 23, so that the auxiliary plate 33 swings to the side close to the scraper 23, and the auxiliary plate 33 is in contact with the teeth of the crushing roller 12 away from the scraper 23. As the disc 22, the scraper 23 and the auxiliary plate 33 rotate, the scraper blade 24 on the auxiliary plate 33 can clean the other side of the teeth of the crushing roller 12, thereby improving the cleaning effect.

[0021] The disc 22, the scraper 23, the auxiliary plate 33 and the fixed rod 21 are provided with a matching component 4, which includes a connecting block 41, which is fixed to the surface of the disc 22, a spring sheet 42 is fixed to the side of the connecting block 41 close to the scraper 23, and the end of the spring sheet 42 away from the connecting block 41 is fixed to the side of the scraper 23 close to the top rod 35, and an active cleaning block 43 is slidably installed on the side of the scraper 23 away from the spring sheet 42, and a push rod 44 is hinged to the side of the active cleaning block 43 close to the disc 22, and the end of the push rod 44 away from the active cleaning block 43 is hinged to the disc 22 The active cleaning block 43 is fixed with a telescopic rod 45 on one side close to the auxiliary plate 33, and a driven cleaning block 46 is hingedly connected to one end of the telescopic rod 45 away from the active cleaning block 43. The driven cleaning block 46 is slidably mounted on the side of the auxiliary plate 33 close to the scraper 23. A bracket 47 is fixed on the surface of the fixed rod 21, and a cross bar 48 is fixed on the inner side of the bracket 47. When the disc 22 rotates to the position of the cross bar 48 with the scraper 23 and the auxiliary plate 33, the scraper 23 is resisted by the cross bar 48, so that the scraper 23 rotates at the position hinged with the disc 22, and the scraper 23 moves closer to the center of the disc 22. The active cleaning block 43 is swung to one side of the auxiliary plate 33, and the push rod 44 hinged to the disc 22 pushes the active cleaning block 43 to move along the scraper 23 to one side of the scraper blade 24, so as to clean the scraper 23 and the scraper blade 24 and prevent plastic residue from remaining on the scraper 23 and the scraper blade 24. At the same time, the active cleaning block 43 pushes the driven cleaning block 46 to move along the auxiliary plate 33 to the side close to the scraper blade 24 through the telescopic rod 45, so that the driven cleaning block 46 cleans the auxiliary plate 33 and the scraper blade 24, thereby improving the overall cleaning effect. The cleaning block 46 is hinged so that when the auxiliary plate 33 swings toward the side close to the scraper 23 under the action of the spring piece 1 34, the active cleaning block 43 is pulled by the push rod 44 and cannot move at this time, and the auxiliary plate 33 and the driven cleaning block 46 can only push the telescopic rod 45 to make the telescopic rod 45 shrink. When the scraper 23 is not resisted by the cross bar 48, the scraper 23 bounces open and resets under the action of the spring piece 2 42. At this time, the push rod 44 pulls the active cleaning block 43 to reset, and the active cleaning block 43 pulls the driven cleaning block 46 to reset through the telescopic rod 45, which will not affect the next cleaning of the crushing roller 12.

[0022] In addition, in this embodiment, a resistance component 5 is provided on the disc 22 and the resistance ring 32, and the resistance component 5 includes a connecting ring 51, and the connecting ring 51 is fixed to the surface of the disc 22, and an active resistance piece 52 is fixed on the surface of the connecting ring 51, and a driven matching piece 53 is fixed on the inner side of the resistance ring 32, and the end of the active resistance piece 52 in contact with the connecting ring 51 is fixed to the connecting ring 51, and the active resistance piece 52 is made of iron and has a certain elasticity, and the end of the active resistance piece 52 away from the connection with the connecting ring 51 is in an active state, when the scraper 24 is subjected to the force of the teeth of the crushing roller 12, the disc 22 and the connecting ring 51 are subjected to the force of rotation, and at this time, the active resistance piece 52 is in contact with the driven matching piece 53, providing a certain resistance to the disc 22, thereby realizing the crushing roller 12 The teeth of the scraper 24 can first apply pressure to the scraper 24, causing the scraper 24 to undergo a certain deformation. Only when the scraper 24 cannot be deformed can the disc 22 be pushed to rotate, ensuring that the scraper 24 can fit well with the teeth of the crushing roller 12, thereby improving the cleaning effect. When the disc 22 rotates, the active resistance piece 52 on the surface of the connecting ring 51 is resisted and deformed, and the active resistance piece 52 moves between the next set of driven matching pieces 53 to complete stability, so that the disc 22 can only rotate when it is subjected to a certain degree of external force, and the rotation angle is certain, thereby preventing the disc 22 from rotating accidentally, resulting in the scraper 23 and the crushing roller 12 not matching the tooth angles when the teeth of the subsequent crushing roller 12 rotate, thereby affecting the normal cleaning effect.

[0023] It is worth noting that there are two groups of crushing mechanisms, which are symmetrically arranged on the machine body 1, two groups of drive motors 11 are fixed on the surface of the machine body 1, and the output shafts of the two groups of drive motors 11 pass through the machine body 1, and the output shafts of the two groups of drive motors 11 are respectively fixed to the two groups of crushing rollers 12. Through the two groups of crushing rollers 12 rotating in opposite directions, the plastic can be crushed well.

[0024] The screening mechanism includes: a screen plate 13, a vibration motor 14, a fixed shaft 15, a spring 16 and a striking block 17. The screen plate 13 is fixed inside the machine body 1, and the vibration motor 14 is fixed on the surface of the machine body 1. The output shaft of the vibration motor 14 passes through the machine body 1, and the output shaft of the vibration motor 14 is fixed to the fixed shaft 15. A striking block 17 is slidably installed on the inner side of the fixed shaft 15. A spring 16 is fixed to the inner side of the fixed shaft 15, and one end of the spring 16 away from the fixed shaft 15 is fixed to the striking block 17. The fixed shaft 15 is driven to rotate by the vibration motor 14. Under the action of the spring 16, when the striking block 17 hits the bottom of the screen plate 13, it can be retracted into the inner side of the fixed shaft 15, and when it is not hit, it can be ejected. The striking block 17 hits the bottom of the screen plate 13 to achieve vibration, thereby improving its screening efficiency.

[0025] Based on the above embodiment, by putting plastic into the machine body 1, the driving motor 11 and the vibration motor 14 are started, and the two groups of crushing rollers 12 crush the plastic. The scraper 23 is limited by the fixed block 26. When the scraper 23 is in a state perpendicular to the crushing roller 12, as the crushing roller 12 slowly rotates, the teeth of the crushing roller 12 abut against the scraper 24, and the scraper 24 is subjected to the force of the teeth of the crushing roller 12 abutting against the scraper 24. The disc 22 and the connecting ring 51 are subjected to the force of rotation. At this time, the active abutment sheet 52 abuts against the driven matching sheet 53, providing a certain resistance to the disc 22, so that the teeth of the crushing roller 12 can first apply pressure to the scraper 24, so that the scraper 24 undergoes a certain deformation. Only when the scraper 24 cannot be deformed, can the disc 22 be pushed to rotate, ensuring that the scraper 24 can fit well with the teeth of the crushing roller 12, thereby improving the cleaning effect.

[0026] At the same time, the push rod 35 moves to the embedded groove provided on the surface of the resistance ring 32, and the resistance ring 32 can no longer apply pressure to the push rod 35. Under the action of the spring piece 34, the auxiliary plate 33 is in a position hinged with the scraper 23, so that the auxiliary plate 33 swings toward the side close to the scraper 23, and the auxiliary plate 33 is in contact with the teeth of the crushing roller 12 away from the scraper 23. As the disc 22, the scraper 23 and the auxiliary plate 33 rotate, the scraper 24 on the auxiliary plate 33 can clean the other side of the teeth of the crushing roller 12, thereby improving the cleaning effect.

[0027] As the pulverizing roller 12 rotates, the teeth of the pulverizing roller 12 and the scraper 24 are relatively displaced, so that the scraper 24 can clean the plastic stuck to the pulverizing roller 12. As the pulverizing roller 12 continues to rotate, the teeth of the pulverizing roller 12 abut against the scraper 24. Since the scraper 24 cannot continue to deform, it can push the scraper 24 and the scraper plate 23, so that the disc 22 rotates a certain angle.

[0028] As the disc 22 rotates, the next set of scrapers 23 rotates over, and as the crushing roller 12 rotates, the teeth of the crushing roller 12 first contact the scraper blades 24 on the next set of scrapers 23, causing the disc 22 to rotate, causing the next set of scrapers 23 to rotate to a state perpendicular to the crushing roller 12 and start working.

[0029] As the disc 22 rotates, when the disc 22 rotates to the position of the cross bar 48 with the scraper 23 and the auxiliary plate 33, the scraper 23 is resisted by the cross bar 48, so that the scraper 23 rotates at the position hinged with the disc 22, and the scraper 23 swings to the side close to the center of the disc 22. At this time, the push rod 44 hinged with the disc 22 pushes the active cleaning block 43 to move along the scraper 23 to the side of the scraper blade 24, so as to clean the scraper 23 and the scraper blade 24 and prevent plastic residue from remaining on the scraper 23 and the scraper blade 24. At the same time, the active cleaning block 43 pushes the driven cleaning block 46 to move along the auxiliary plate 33 to the side close to the scraper blade 24 through the telescopic rod 45, so that the driven cleaning block 46 cleans the auxiliary plate 33 and the scraper blade 24. The cleaning is carried out to improve the overall cleaning effect, and one end of the telescopic rod 45 is fixed to the active cleaning block 43, and the other end is hinged to the driven cleaning block 46, so that when the auxiliary plate 33 swings to the side close to the scraper 23 under the action of the spring piece 1 34, the active cleaning block 43 is pulled by the push rod 44 and cannot move at this time, and then the auxiliary plate 33 and the driven cleaning block 46 can only push the telescopic rod 45, so that the telescopic rod 45 shrinks, and when the scraper 23 is not resisted by the cross bar 48, under the action of the spring piece 2 42, the scraper 23 bounces open and resets, and at this time the push rod 44 pulls the active cleaning block 43 to reset, and the active cleaning block 43 pulls the driven cleaning block 46 to reset through the telescopic rod 45, which will not affect the next cleaning of the crushing roller 12.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
