[0032] like Figure 1 - Figure 5 As shown, the present application provides a plastic pelletizer 10, comprising:

[0033] Body 10;

[0034] A pelletizing mechanism 20, the pelletizing mechanism 20 is disposed in the machine body 10;

[0035] The cleaning mechanism 30 includes a connecting frame 31, a driving assembly 32, a rotating seat 33, an air jet 34 and a sweeping brush 35. The connecting frame 31 is movably connected to the machine body 10 and is located above the pelletizing mechanism 20. The driving assembly 32 is connected to the connecting frame 31 and is connected to the rotating seat 33. The rotating seat 33 is horizontally arranged with the pelletizing mechanism 20 to drive the rotating seat 33 to rotate. The air jet 34 and the sweeping brush 35 are arranged at intervals along the circumference of the rotating seat 33. The rotating seat 33 is rotated to drive the air jet 34 or the sweeping brush 35 to be arranged toward the pelletizing mechanism 20.

[0036] The electric control mechanism 40 is electrically connected to the pelletizing mechanism 20 and the cleaning mechanism 30 .

[0037] The cleaning mechanism 30 is mainly composed of a connecting frame 31, a powerful driving assembly 32, a flexibly rotating rotating seat 33, an efficient and clean jetting member 34, and a meticulous sweeping member 35. The connecting frame 31 is firmly mounted on the machine body 10 in a movable connection manner, and is cleverly arranged above the pelletizing mechanism 20, ensuring a reasonable spatial layout and convenient operation. The driving assembly 32 is tightly connected to the connecting frame 31 and seamlessly docked with the rotating seat 33, realizing efficient power transmission. The rotating seat 33 is placed horizontally with the pelletizing mechanism 20, and the rotating seat 33 can be flexibly driven to rotate through the precise control of the driving assembly 32. The jetting member 34 and the sweeping member 35 are cleverly distributed at intervals along the circumference of the rotating seat 33. Rotating the rotating seat 33 can easily drive the jetting member 34 or the sweeping member 35 toward the pelletizing mechanism 20 for a full range of cleaning operations. The jetting member 34 can be a spray gun, an air gun, etc., and the sweeping member 35 can be a wool sweeper, a rubber sweeper, etc.

[0038] A complete cleaning mechanism 30, its core components include a connecting frame 31, a powerful driving assembly 32, a flexible rotating seat 33, an air jet 34 for efficient cleaning, and a meticulous sweeping brush 35. The connecting frame 31 can be stably mounted on the machine body 10 by adopting a movable connection, and its position is cleverly arranged above the pelletizing mechanism 20, which not only ensures the rationality of the entire space layout, but also makes the operation more convenient.

[0039] The driving assembly 32 is tightly connected to the connecting frame 31 and seamlessly connected to the rotating seat 33, so that the power can be efficiently transmitted and the entire cleaning mechanism 30 can operate smoothly. The rotating seat 33 is placed horizontally with the pelletizing mechanism 20. Through the precise control of the driving assembly 32, the rotating seat 33 can be flexibly driven to rotate, and the jet part 34 or the sweeping brush part 35 can be changed to clean the pelletizing mechanism 20.

[0040] The air jets 34 and the sweeping brushes 35 are cleverly distributed at intervals along the circumference of the rotating seat 33, so that the air jets 34 or the sweeping brushes 35 can be easily driven toward the pelletizing mechanism 20 by simply rotating the rotating seat 33 to perform a full range of cleaning operations. This design not only improves the cleaning efficiency, but also makes the cleaning process more convenient and quick.

[0041] As the core of the whole system, the electric control mechanism 40 closely connects the pelletizing mechanism 20 and the cleaning mechanism 30 with precise electric control technology, thus realizing efficient control and management of both. Through the careful regulation of the electric control mechanism 40, the pelletizing mechanism 20 and the cleaning mechanism 30 are ensured to work together to achieve the best production efficiency and cleaning effect.

[0042] With the fine design of the cleaning mechanism 30, we have further enhanced its performance. The jet part 34 adopts high-pressure jet technology, which can generate a strong airflow to effectively blow away the fine particles and dust attached to the pelletizing mechanism 20. The sweeping brush part 35 is made of wear-resistant and soft material, which can gently remove the residues that are difficult to blow away, ensuring the cleanliness of the pelletizing mechanism 20.

[0043] In addition, we have also optimized the rotating seat 33 to make it rotate more smoothly and reduce the wear on the jet part 34 and the sweeping brush part 35. At the same time, the design of the rotating seat 33 also takes into account the balance of its own weight and load, ensuring the stability and reliability of the entire cleaning mechanism 30 during long-term work.

[0044] As the core of the whole system, the electric control mechanism 40 has been upgraded to be intelligent. Through precise sensors and efficient algorithms, the electric control mechanism 40 can monitor the working status of the pelletizing mechanism 20 and the cleaning mechanism 30 in real time and make automatic adjustments as needed. For example, when the pelletizing mechanism 20 starts working, the electric control mechanism 40 will automatically start the cleaning mechanism 30 and intelligently adjust the working intensity of the jet part 34 and the sweeping brush part 35 according to parameters such as pelletizing speed and particle size to achieve the best cleaning effect.

[0045] In addition, the electric control mechanism 40 also has fault self-diagnosis and remote monitoring functions. Once a system fault occurs, the electric control mechanism 40 will immediately sound an alarm and send the fault information to the operator through the remote communication module, so that they can troubleshoot the fault in time and ensure the continuous and stable operation of the system.

[0046] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art: the present application is provided with a cleaning mechanism 30, the cleaning mechanism 30 uses a rotating seat 33 to connect the jet component 34 and the sweeping brush component 35, and the driving assembly 32 drives the rotating seat 33 to rotate, so that the jet component 34 and the sweeping brush component 35 can perform jet cleaning and sweeping brush cleaning on the pelletizing mechanism 20 in turn, the sweeping brush can sweep off the plastic pellets, and the jet can blow off the plastic pellets with strong adhesion. Then the pelletizing mechanism 20 and the cleaning mechanism 30 are controlled by the electric control mechanism 40, the rotation of the pelletizing mechanism 20 and the alternating rotation of the cleaning mechanism 30 are controlled, and the automatic high-intensity cleaning of the cutting disc is realized through the alternating cleaning of the two cleaning devices, with high cleaning efficiency and high cleaning strength.

[0047] Furthermore, the plastic pelletizer 10 also includes an ion blower, which is connected to the jet part 34. The ion blower can make the jet part 34 blow out ion wind to effectively remove static electricity and dust on the surface of the plastic particles. The working principle of the ion blower is to generate a large number of positive and negative ions through a high-voltage power supply, and blow these ions out through the jet part 34. When the ion wind contacts the plastic particles, it will neutralize the static electricity on the surface of the particles and absorb the dust. On the one hand, it can prevent static electricity from causing the plastic particles to be adsorbed on the surface of the pelletizer 20, thereby improving the effect of blowing off, and on the other hand, it can achieve the purpose of cleaning the particles.

[0048] In addition, the ion blower also has the function of adjusting the ion concentration. By adjusting the parameters of the ion blower, the ion wind blown out by the jet part 34 can have different ion concentrations to meet the cleaning requirements of different plastic particles. This flexibility enables the plastic pelletizer 10 to adapt to more application scenarios, improving the versatility and practicality of the equipment. Moreover, the ion blower does not generate noise and pollution during operation, meeting environmental protection requirements. At the same time, it is easy to operate and has low maintenance costs, which also reduces the user's cost of use.

[0049] Further, the driving assembly 32 includes a first driving member 321 and a bearing 322, the bearing 322 is sleeved on the connecting frame 31, the rotating seat 33 is connected to the outside of the bearing 322, and the first driving member is drivingly connected to the connecting frame 31 and drivingly connected to the rotating seat 33. The first driving member 321 can drive the rotating seat 33 to rotate. In another embodiment, the first driving member 321 can drive the rotating seat 33 to rotate and move.

[0050] Furthermore, the first driving member 321 is a rotating cylinder, and the first driving member 321 drives the rotating seat 33 to reciprocate and rotate along the extension of the pelletizing mechanism 20 .

[0051] In the precise operation of the pelletizing mechanism 20, the rotary cylinder plays a vital role as the first driving member 321. When the rotary cylinder starts to work, its stable rotation force drives the rotary seat 33 to reciprocate along the extension direction of the pelletizing mechanism 20. This movement not only ensures the stability of the pelletizing process, but also greatly improves the efficiency and precision of pelletizing.

[0052] At the same time, the rotation of the rotating cylinder also drives the rotation of the rotating seat 33. This rotation can make the rotating seat 33 rotate to drive the air jet member 34 and the sweeping member 35 to rotate, and then the air jet member 34 and the sweeping member 35 can be changed to face the pelletizing mechanism 20 to perform different cleaning operations.

[0053] In addition, the rotary cylinder drive method also makes the entire pelletizing process more energy-efficient and environmentally friendly. Compared with the traditional mechanical drive method, the rotary cylinder consumes less energy, makes less noise, and pollutes the environment less. At the same time, due to its compact structure and easy maintenance, it also greatly reduces production and maintenance costs.

[0054] Furthermore, the air-jet member 34 and the brush member 35 are respectively connected to two opposite sides of the rotating base 33 in the circumferential direction.

[0055] The rotating seat 33 drives the jetting member 34 and the sweeping brush member 35 to rotate. The jetting member 34 first performs jetting operation to blow off most of the plastic particles, and then sweeps them away through the sweeping brush member 35, and finally performs jetting to blow them off again. This cooperative operation not only improves the cleaning efficiency, but also makes the entire cleaning process smoother and more efficient. Setting them on opposite sides also avoids mutual interference between the two cleaning devices, reflecting the working independence of the two cleaning devices.

[0056] Furthermore, the plastic pelletizer 10 further includes a second driving member 50, the driving end of which drives the connecting frame 31 to drive the connecting frame 31 to reciprocate along the extension of the pelletizing mechanism 20. This arrangement allows the cleaning mechanism 30 to cover the range of the pelletizing mechanism 20, thereby increasing the cleaning range.

[0057] Furthermore, a slide rail 11 is further provided on the top of the machine body 10, and the connecting frame 31 is slidably connected to the slide rail 11. With such a configuration, the moving path of the connecting frame 31 is maintained.

[0058] Furthermore, there are multiple cleaning mechanisms 30, and multiple connecting members 60 are arranged at intervals along the extension of the pelletizing mechanism 20. The multiple cleaning mechanisms 30 can cover the range of the pelletizing mechanism 20, and the multiple cleaning mechanisms 30 perform synchronous cleaning, thereby improving the cleaning efficiency.

[0059] Furthermore, the plastic pelletizer 10 further includes a connecting member 60, which connects the connecting frames 31 of two adjacent pelletizer mechanisms 20, and the second driving member 50 drives the pelletizer mechanism 20 located at the edge. The setting of the connecting member 60 can keep the multiple cleaning mechanisms 30 moving synchronously, realize synchronous cleaning, and avoid mutual interference between the multiple cleaning mechanisms 30.

[0060] Furthermore, the driving end of the second driving member 50 is fixedly connected to the connecting rod. In this way, the driving end of the second driving member 50 keeps the same moving path as the connecting rod, which has a simple structure, convenient operation and easy installation.

[0061] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
