[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] This embodiment is used to crush waste plastics to produce plastic particles. The crushing mechanism proposed in this embodiment can be automatically adjusted according to the size of the plastic particles produced during actual use, thereby solving the problem of poor crushing effect and uneven size of plastic particles caused by existing crushing equipment.

[0020] like Figure 1-Figure 11 As shown, this embodiment includes a feedback-adjustable pulverizing mechanism 100, a particle diameter sensing component 200 and a bottom material box 300. The feedback-adjustable pulverizing mechanism 100 is mainly used to crush plastics. The feedback-adjustable pulverizing mechanism 100 is arranged on the bottom material box 300. The plastic particles crushed by the feedback-adjustable pulverizing 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 pulverizing mechanism 100, and adjust the feedback-adjustable pulverizing mechanism 100 according to the detected size of the plastic particles.

[0021] The specific structure of the feedback-adjustable pulverizing mechanism 100 includes a pulverizing roller 101 and a spacing adjustment component 105. A plurality of pulverizing rollers 101 are coaxially arranged. The feedback-adjustable pulverizing mechanism 100 drives the plurality of pulverizing rollers 101 to rotate synchronously to pulverize the plastic. At the same time, a spacing adjustment component 105 is provided to control the distance between adjacent pulverizing rollers 101. When the distance between adjacent pulverizing rollers 101 is reduced, the size and diameter of the crushed plastic particles will also be reduced accordingly. Similarly, when the distance between the pulverizing rollers 101 is increased, the size and diameter of the plastic particles will be increased accordingly. Then, the spacing adjustment component 105 and the particle diameter sensing component 200 are connected. The spacing adjustment component 105 is adjusted in real time according to the diameter detected by the particle diameter sensing component 200, thereby realizing feedback adjustment of the feedback-adjustable pulverizing mechanism 100. It can be automatically adjusted according to actual production conditions without manual intervention, thereby greatly improving production efficiency.

[0022] When this embodiment is used, the particle diameter sensing component 200 is first installed inside the bottom material box 300, and the crushing roller 101 and the spacing adjustment component 105 are installed on the top of the bottom material box 300. Then, the feedback adjustment type crushing mechanism 100 is started to drive the crushing roller 101 to rotate. At this time, the plastic is placed on the crushing roller 101 for crushing. The crushing roller 101 crushes the plastic to produce plastic particles that fall into the bottom material box 300. After entering the bottom material box 300, the plastic particles first contact the particle diameter sensing component 200. The particle diameter sensing component 200 detects the material diameter size of the plastic particles and determines whether the existing particle material 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 material diameter size detected by the particle diameter sensing component 200 meets the expected requirements of the target.

[0023] The particle diameter sensing component 200 proposed in this embodiment includes a partition 201 and a pressure sensor 203, which are arranged inside the bottom material box 300. The partition 201 is arranged on the pressure sensor 203. The partition 201 is provided with a linear array of drop holes 205. The partition 201 is located below the crushing roller 101. When the feedback-adjustable crushing mechanism 100 crushes the plastic, the plastic particles generated fall into the bottom material box 300 and first contact the partition 201. At this time, the plastic particles smaller than the size of the drop hole 205 fall through the drop hole 205, while the plastic particles larger than the size of the drop hole 205 cannot pass through the drop hole 205. The material hole 205, therefore, the plastic particles whose size is larger than the material hole 205 are accumulated on the partition 201, and the pressure sensor 203 reflects the gravity of the plastic particles accumulated on the partition 201 by detecting the pressure value received by itself from the partition 201. If the pressure value detected by the pressure sensor 203 continues to increase, it means that the size of the plastic particles crushed by the crushing roller 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 crushing roller 101 to move axially, shortens the distance between the crushing rollers 101, thereby increasing the crushing capacity and reducing the size of the produced plastic particles.

[0024] When this embodiment is used, the partition 201 is first set according to the required particle size, so that the size of the drop hole 205 on the partition 201 is equal to the required particle size, and then the plastic to be crushed is placed in the feedback adjustment type pulverizing mechanism 100 for pulverization, and the generated plastic particles fall into the bottom material box 300 and then fall onto the partition 201. The plastic particles that meet the required size requirements pass through the drop hole 205 on the partition 201 and fall down, while the plastic particles that are too large and do not meet the requirements cannot pass through the drop hole 205 and accumulate on the partition 201, generating pressure on the pressure sensor 203. After detecting the pressure change, the pressure sensor 203 transmits a signal to the spacing adjustment component 105, so that the spacing adjustment component 105 controls the distance between adjacent pulverizing rollers 101 to reduce, thereby pulverizing the plastic particles more finely.

[0025] After the first crushing is completed, all the plastic particles are put into the feedback-adjustable crushing mechanism 100 for secondary crushing until the pressure sensor 203 no longer detects continuous pressure changes, which means that all the plastic particles can pass through the drop hole 205 and fall from the partition 201, which proves that the size of all the plastic particles meets the expected requirements, and the crushing work is completed at this time.

[0026] The particle diameter sensing component 200 proposed in this embodiment also 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 direction of the resultant force vector 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 extension and retraction amount of the hydraulic rod of the adjustment hydraulic cylinder 107.

[0027] In this embodiment, an adjusting spring 106 is set between adjacent crushing rollers 101, and the distance between the crushing rollers 101 is adjusted by pushing at one end of the crushing roller 101 through the adjusting hydraulic cylinder 107. The adjusting hydraulic cylinder 107 can fix the distance between the crushing rollers 101 by maintaining pressure. At the same time, the pressure provided by the adjusting hydraulic cylinder 107 is relatively large, which is suitable for pushing multiple crushing rollers 101.

[0028] When this embodiment is used, the pressure sensor 203 transmits the detected pressure signal to the PLC controller 204, and the PLC controller 204 processes the pressure signal to determine whether it is necessary to adjust the spacing between 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 hydraulic cylinder 107 to extend, push the crushing rollers 101 closer to each other, and compress the adjustment spring 106 at the same time, so that the spacing between the crushing rollers 101 is reduced, thereby reducing the size and diameter of the plastic particles generated by the crushing rollers 101.

[0029] At the same time, in this embodiment, a tapered roller bearing 108 is provided to connect the hydraulic rod of the adjusting hydraulic cylinder 107 and the crushing roller 101. When the hydraulic rod of the adjusting hydraulic cylinder 107 applies pressure to the crushing roller 101, it does not affect the rotation of the crushing roller 101. At the same time, the tapered roller bearing 108 can withstand the axial pressure of the adjusting hydraulic cylinder 107, so as to adjust the spacing of the crushing roller 101 while the crushing roller 101 is performing the crushing work.

[0030] The particle diameter sensing component 200 proposed in this embodiment also includes a slide bar 202 and a sensing spring 206. The slide bar 202 is fixed inside the bottom material box 300, and the partition 201 is slidably arranged on the slide bar 202. The two ends of the sensing spring 206 are respectively connected to the pressure sensor 203 and the partition 201. When plastic particles accumulate on the partition 201, the partition 201 transfers the pressure to the sensing spring 206 to compress the sensing spring 206. At the same time, the partition 201 slides downward on the slide bar 202. The sensing spring 206 is provided to buffer the plastic particles falling onto the partition 201, so as to prevent the impact force of the falling plastic particles from pushing the plastic particles accumulated on the partition 201 off the partition 201, thereby ensuring the accuracy of the particle diameter sensing component 200 in detecting the diameter of the plastic particles and reducing the vibration and noise of the entire equipment.

[0031] The feedback adjustment type pulverizing mechanism 100 proposed in this embodiment further includes a pulverizing shaft 102, a support frame 103 and a pulverizing motor 104, wherein the pulverizing shaft 102 and the pulverizing motor 104 are arranged on the support frame 103, the support frame 103 is arranged on the bottom material box 300, the pulverizing shaft 102 is rotatably connected with the support frame 103, and the pulverizing motor 104 drives the rotation of the pulverizing shaft 102; The pulverizing roller 101 is fixed on the pulverizing shaft 102 , and the pulverizing roller 101 rotates synchronously with the pulverizing shaft 102 .

[0032] When this embodiment is used, the crushing motor 104 drives the crushing shaft 102 to rotate on the support frame 103. When the crushing shaft 102 rotates, it drives the crushing roller 101 to rotate synchronously. When the crushing roller 101 rotates, the plastic is crushed. This embodiment uses the crushing motor 104 to drive the rotation of the crushing roller 101, which can achieve a better crushing effect and generate less noise.

[0033] In this embodiment, crushing teeth 109 are arranged in an array on the surface of the crushing roller 101. The crushing teeth 109 assist in crushing the plastic when the crushing roller 101 rotates, thereby improving the crushing effect.

[0034] At the same time, the crushing teeth 109 are movably connected to the crushing roller 101, and the crushing teeth 109 can be removed from the crushing roller 101. Different crushing teeth 109 can be replaced according to different types of plastics, thereby improving the applicability of the feedback-adjustable crushing mechanism 100 to different types of plastics.

[0035] The top of the bottom material box 300 proposed in this embodiment is provided with a positioning slot 303, the support frame 103 is fixedly set in the positioning slot 303, the side of the bottom material box 300 is provided with an extension plate 304, and the spacing adjustment component 105 is arranged on the extension plate 304. The support frame 103 is fixedly set in the positioning slot 303, and the spacing adjustment component 105 is fixedly set on the extension plate 304, so as to improve the overall stability and structural strength of the device and avoid looseness and vibration during operation.

[0036] The top of the bottom material box 300 proposed in this embodiment is provided with a top feed port 301, and the top feed port 301 is located below the crushing roller 101. Top guide plates 302 are provided on both sides of the top feed port 301. The top guide plates 302 are provided to guide the plastic to ensure 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 feed port 301 through the top feed port 301 for collection.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto.
