[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0030] This embodiment is used to crush waste plastics to manufacture plastic particles. The crushing mechanism proposed in this embodiment can be automatically adjusted according to the size of the plastic particles manufactured during actual use, solving the problems of poor crushing effect and uneven size of plastic particles in existing crushing equipment.

[0031] As Figures 1-11 shown, this embodiment includes a feedback-adjustable crushing mechanism 100, a particle diameter sensing component 200, and a bottom material box 300. The feedback-adjustable crushing mechanism 100 is mainly used to crush plastics. The feedback-adjustable crushing mechanism 100 is arranged on the bottom material box 300. The plastic particles crushed by the feedback-adjustable crushing mechanism 100 fall into the bottom material box 300 for collection. At the same time, a particle diameter sensing component 200 is arranged inside the bottom material box 300. The particle diameter sensing component 200 is used to detect the size of the plastic particles crushed by the feedback-adjustable crushing mechanism 100 and adjust the feedback-adjustable crushing mechanism 100 according to the detected size of the plastic particles.

[0032] The specific structure of the feedback adjustment type crushing mechanism 100 includes crushing rollers 101 and a spacing adjustment component 105. A plurality of crushing rollers 101 are coaxially arranged. The feedback adjustment type crushing mechanism 100 drives the plurality of crushing rollers 101 to rotate synchronously to crush plastics. At the same time, a spacing adjustment component 105 is provided to control the distance between adjacent crushing rollers 101. When the distance between adjacent crushing rollers 101 is reduced, the size and diameter of the plastic particles generated by crushing will also be reduced accordingly. Similarly, when the distance between the crushing rollers 101 is increased, the size and diameter of the plastic particles generated will increase accordingly. Furthermore, the spacing adjustment component 105 and the particle diameter sensing component 200 are connected, and the spacing adjustment component 105 is adjusted in real time according to the particle diameter detected by the particle diameter sensing component 200, realizing the feedback adjustment of the feedback adjustment type crushing mechanism 100, which can be automatically adjusted according to the actual production situation without manual intervention, greatly improving the production efficiency.

[0033] In the specific use of this embodiment, first, the particle diameter sensing component 200 is installed inside the bottom material box 300, and the crushing rollers 101 and the spacing adjustment component 105 are installed on the top of the bottom material box 300. Subsequently, the feedback adjustment type crushing mechanism 100 is started to drive the crushing rollers 101 to rotate. At this time, plastics are placed on the crushing rollers 101 for crushing. The crushing rollers 101 crush the plastics to generate plastic particles that fall into the bottom material box 300. After the plastic particles enter the bottom material box 300, they first come into contact with the particle diameter sensing component 200. The particle diameter sensing component 200 detects the particle diameter size of the plastic particles and judges whether the existing particle diameter size meets the requirements, and feeds back the adjustment instruction to the spacing adjustment component 105. After receiving the signal from the particle diameter sensing component 200, the spacing adjustment component 105 adjusts the distance between adjacent crushing rollers 101 until the particle diameter size detected by the particle diameter sensing component 200 reaches the target expected requirement.

[0034] The pellet size sensing component 200 proposed in this embodiment includes a partition plate 201 and a pressure sensor 203. The partition plate 201 and the pressure sensor 203 are arranged inside the bottom bin 300. The partition plate 201 is disposed on the pressure sensor 203. The partition plate 201 is linearly and arrayedly provided with material dropping holes 205. The partition plate 201 is located below the crushing rollers 101. When the plastic particles generated during the crushing of the plastic by the feedback adjustment type crushing mechanism 100 fall into the bottom bin 300, they first come into contact with the partition plate 201. At this time, the plastic particles with a size smaller than the size of the material dropping holes 205 pass through the material dropping holes 205 and fall down, while the plastic particles with a size larger than the size of the material dropping holes 205 cannot pass through the material dropping holes 205. Therefore, the plastic particles with a size larger than the size of the material dropping holes 205 accumulate on the partition plate 201. The pressure sensor 203 reflects the gravity of the plastic particles accumulated on the partition plate 201 by detecting the magnitude of the pressure exerted on itself by the partition plate 201. If the pressure value detected by the pressure sensor 203 continues to increase, it indicates that the size of the plastic particles generated by the crushing of the crushing rollers 101 is too large. At this time, the pressure sensor 203 transmits a signal to the spacing adjustment component 105, so that the spacing adjustment component 105 controls the axial movement of the crushing rollers 101 to reduce the distance between the crushing rollers 101, thereby increasing the crushing ability and reducing the size of the generated plastic particles.

[0035] When this embodiment is in use, first set the partition plate 201 according to the required pellet size, so that the size of the material dropping holes 205 on the partition plate 201 is equal to the required pellet size. Subsequently, put the plastic to be crushed into the feedback adjustment type crushing mechanism 100 for crushing. The generated plastic particles fall into the bottom bin 300 and then onto the partition plate 201. The plastic particles that meet the required size requirements pass through the material dropping holes 205 on the partition plate 201 and fall down, while the plastic particles with a size too large and not meeting the requirements cannot pass through the material dropping holes 205 and accumulate on the partition plate 201, generating pressure on the pressure sensor 203. After the pressure sensor 203 detects the pressure change, it transmits a signal to the spacing adjustment component 105, so that the spacing adjustment component 105 controls the distance between adjacent crushing rollers 101 to be reduced, thereby performing more refined crushing on the plastic particles.

[0036] After one crushing is completed, put all the plastic particles into the feedback adjustment type crushing mechanism 100 again for secondary crushing until the pressure sensor 203 no longer detects continuous pressure change, which indicates that all the plastic particles can pass through the material dropping holes 205 and fall from the partition plate 201, that is, it is proved that the sizes of all the plastic particles have reached the expected requirements. At this time, the crushing work is completed.

[0037] The pellet diameter sensing component 200 proposed in this embodiment further includes a PLC controller 204. The pressure sensor 203 is electrically connected to the PLC controller 204. The spacing adjustment component 105 includes an adjustment spring 106, an adjustment hydraulic cylinder 107, and a tapered roller bearing 108. The adjustment spring 106 is arranged between adjacent crushing rollers 101. The adjustment hydraulic cylinder 107 is arranged at one end of the crushing roller 101. The resultant force vector direction output by the adjustment hydraulic cylinder 107 coincides with the central axis of the crushing roller 101. The tapered roller bearing 108 is arranged between the adjustment hydraulic cylinder 107 and the crushing roller 101. The PLC controller 204 is connected to the adjustment hydraulic cylinder 107, and the PLC controller 204 controls the telescopic amount of the hydraulic rod of the adjustment hydraulic cylinder 107.

[0038] In this embodiment, an adjustment spring 106 is arranged between adjacent crushing rollers 101, and the adjustment hydraulic cylinder 107 is used to push at one end of the crushing roller 101 to realize the adjustment of the distance between the crushing rollers 101. The adjustment hydraulic cylinder 107 can fix the distance between the crushing rollers 101 by maintaining pressure. At the same time, the pressure provided by the adjustment hydraulic cylinder 107 is relatively large, which is suitable for pushing multiple crushing rollers 101.

[0039] When this embodiment is specifically used, the pressure sensor 203 transmits the detected pressure signal to the PLC controller 204. The PLC controller 204 processes the pressure signal to determine whether it is necessary to adjust the spacing of the crushing rollers 101. If the PLC controller 204 determines that the reading of the pressure sensor 203 is continuously increasing, the PLC controller 204 controls the hydraulic rod of the adjustment hydraulic cylinder 107 to extend, pushing the crushing rollers 101 closer to each other, and at the same time compressing the adjustment spring 106, so that the spacing between the crushing rollers 101 is reduced, thereby reducing the size and diameter of the plastic pellets generated by the crushing rollers 101.

[0040] At the same time, this embodiment is provided with a tapered roller bearing 108 for connecting the hydraulic rod of the adjustment hydraulic cylinder 107 and the crushing roller 101, which does not affect the rotation of the crushing roller 101 when the hydraulic rod of the adjustment hydraulic cylinder 107 applies pressure to the crushing roller 101. At the same time, the tapered roller bearing 108 can bear the axial pressure of the adjustment hydraulic cylinder 107, realizing the adjustment of the spacing of the crushing roller 101 while the crushing roller 101 is performing the crushing work.

[0041] The particle diameter sensing component 200 proposed in this embodiment further includes a sliding rod 202 and a sensing spring 206. The sliding rod 202 is fixedly arranged inside the bottom material box 300. The partition plate 201 is slidably arranged on the sliding rod 202. The two ends of the sensing spring 206 are respectively connected to the pressure sensor 203 and the partition plate 201. When plastic particles accumulate on the partition plate 201, the partition plate 201 transmits the pressure to the sensing spring 206, causing the sensing spring 206 to compress. At the same time, the partition plate 201 slides downward on the sliding rod 202. By setting the sensing spring 206, it buffers the plastic particles falling onto the partition plate 201, avoiding the impact force of the falling plastic particles from pushing the plastic particles accumulated on the partition plate 201 off the partition plate 201, ensuring the accuracy of the particle diameter detection of the plastic particles by the particle diameter sensing component 200, and at the same time reducing the vibration and noise of the overall equipment.

[0042] The feedback adjustment type crushing mechanism 100 proposed in this embodiment further includes a crushing rotating shaft 102, a support frame 103, and a crushing motor 104. The crushing rotating shaft 102 and the crushing motor 104 are arranged on the support frame 103. The support frame 103 is arranged on the bottom material box 300. The crushing rotating shaft 102 is rotatably connected to the support frame 103. The crushing motor 104 drives the rotation of the crushing rotating shaft 102;

[0043] The crushing roller 101 is fixedly arranged on the crushing rotating shaft 102, and the crushing roller 101 rotates synchronously with the crushing rotating shaft 102.

[0044] When this embodiment is specifically used, the crushing motor 104 drives the crushing rotating shaft 102 to rotate on the support frame 103. When the crushing rotating shaft 102 rotates, it drives the crushing roller 101 to rotate synchronously. When the crushing roller 101 rotates, it crushes the plastic. In this embodiment, the crushing motor 104 is used to drive the rotation of the crushing roller 101, which can achieve a better crushing effect and at the same time generate less noise.

[0045] In this embodiment, crushing teeth 109 are arrayed on the surface of the crushing roller 101. When the crushing teeth 109 rotate with the crushing roller 101, they assist in crushing the plastic and improve the crushing effect.

[0046] At the same time, the crushing teeth 109 are movably connected to the crushing roller 101, and the crushing teeth 109 can be disassembled from the crushing roller 101. Different crushing teeth 109 can be replaced according to different plastic types, improving the applicability of the feedback adjustment type crushing mechanism 100 to different types of plastics.

[0047] The top end of the bottom material box 300 proposed in this embodiment is provided with a positioning slot 303, the support frame 103 is fixedly arranged in the positioning slot 303, the side of the bottom material box 300 is provided with an extension plate 304, and the spacing adjustment assembly 105 is arranged on the extension plate 304. The support frame 103 is fixedly arranged in the positioning slot 303, and at the same time the spacing adjustment assembly 105 is fixedly arranged on the extension plate 304, which improves the overall stability and structural strength of the device and avoids loosening and vibration during the working process.

[0048] The top end of the bottom material box 300 proposed in this embodiment is provided with a top feeding port 301, the top feeding port 301 is located below the crushing rollers 101, and both sides of the top feeding port 301 are provided with top guide plates 302. By arranging the top guide plates 302 to guide the plastic, it is ensured that the plastic can smoothly enter between the crushing rollers 101 for crushing. At the same time, the plastic particles generated by the crushing fall into the top feeding port 301 through the top feeding port 301 for collection.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0050] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the spirit of the present invention, they shall fall within the protection scope of the present invention.
