[0002] In the granulation process of resistor components, the stability and positioning accuracy of the feeding device directly affect the subsequent processing quality and efficiency. Traditional feeding devices mostly use mechanical clamping or ordinary conveyor belt structures, which have the following technical defects:

[0003] Firstly, mechanical clamping is prone to uneven clamping force due to dimensional deviations or surface characteristics of the resistive components, which can cause the resistive components to shift, tilt, or fall off during the conveying process, affecting the consistency of the folding process.

[0004] Secondly, ordinary conveyor belts lack an effective fixing mechanism. The resistive components are easily displaced by vibration or inertia during transportation, making it difficult to maintain the preset posture and direction, resulting in deviation of the folded particle position.

Therefore, there is an urgent need for a material conveying device that combines stable adsorption, precise positioning, and efficient conveying to address the quality defects and efficiency bottlenecks caused by unstable conveying during the granulation of resistive components.

[0036] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of a feeding device for a pelletizing machine.

[0037] like Figures 1-8 As shown, a feeding device for a pelletizing machine according to the present invention includes a housing 100 and a resistor 800. A feeding mechanism 110 is mounted on the front side of the left end of the housing 100. The feeding mechanism 110 is used to feed the resistor 800. A conveying assembly is mounted on the rear side of the left end of the housing 100. The conveying assembly is used for positioning and conveying the resistor 800 for pelletizing.

[0038] A defect identification mechanism 120 is installed on the front side of the feeding mechanism 110, and the defect identification mechanism 120 is used to detect defects in the resistor 800; a display device 130 is installed on the rear side of the front side of the chassis 100, and the display device 130 is used in conjunction with the defect identification mechanism 120.

[0039] Among them, the feeding mechanism 110 is a three-axis conveying device. Specifically, the three-axis conveying device includes two linear modules for longitudinal and horizontal movement, as well as an electric telescopic tube that can be pushed up and down. In this way, the three-axis conveying device is used to transport the resistor 800 to the front bottom of the telescopic component 400. When the resistor 800 is lifted by the chassis 100, the defect detection mechanism 120 can be used to detect defects in the resistor 800.

[0040] The surface defects of the resistor 800 are detected by a CCD camera and a light source in conjunction with a display device 130.

[0041] A pelletizing mechanism 140 is installed at the end of the housing 100 and at the output end of the conveying assembly. The pelletizing mechanism 140 is used to pelletize the resistor 800. A material recycling mechanism 150 is installed on the left side of the housing 100. The material recycling mechanism 150 works in conjunction with the pelletizing mechanism 140. After the pelletizing mechanism 140 pelletizes the resistor 800, it is sent into the material recycling mechanism 150 for recycling and storage.

[0042] Specifically, the conveying assembly includes a negative pressure belt 210 for storing and conveying the resistive element 800, wherein a plurality of negative pressure holes 220 are provided through the surface of the negative pressure belt 210 for driving the negative pressure belt 210.

[0043] Meanwhile, the inner cavity of the negative pressure belt 210 is provided with a vacuum box 300, and the end of the vacuum box 300 is provided with an air inlet mesh 310 that works in conjunction with the negative pressure hole 220. When the vacuum pump 330 is working, it can perform vacuum treatment on the vacuum box 300, thereby performing negative pressure treatment on the adjacent negative pressure hole 220 groove through the air inlet mesh 310. In this way, when the resistor 800 is stored on the negative pressure belt 210, the resistor 800 can be attracted and transported.

[0044] To install the negative pressure belt 210, mounting brackets 200 are symmetrically installed on the front and rear sides of the negative pressure belt 210, and the mounting brackets 200 are mounted on the end of the mounting box 100 and located behind the feeding mechanism 110.

[0045] To drive the negative pressure belt 210, a drive motor 230 is provided on the left side of the rear end of the mounting frame 200. The drive motor 230 is fastened to the back surface of the mounting frame 200 located on the rear side by bolts. The drive motor 230 serves as a power source to drive the transmission shaft 231 and the transmission disc 232, thereby driving the negative pressure belt 210 to move back and forth. The vacuum box 300 includes two transmission shafts 231 that pass through the left and right ends of the surface of the mounting frame 200. The transmission shafts 231 are symmetrically arranged on the left and right ends of the mounting frame 200 along the axis. The connection between the transmission shafts 231 and the mounting frame 200 is movably connected by bearings.

[0046] like Figure 7 As shown, a transmission disc 232 is sleeved in the middle of the surface of the transmission shaft 231, and the outer surface of the transmission disc 232 is in contact with the surface of the negative pressure belt 210. When the transmission disc 232 rotates, it can drive the negative pressure belt 210 to rotate, thereby using the negative pressure belt 210 to transport the resistor 800.

[0047] As a further optimization of this solution, such as Figure 5 and Figure 6 As shown, in order to guide the negative pressure belt 210, a plurality of guide reels 240 are provided on the bottom of the surface of the negative pressure belt 210, and the guide reels 240 are movably mounted below the mounting frame 200 via bearings and support seats.

[0048] When the negative pressure belt 210 moves, its surface comes into contact with the surface of the guide disc 240;

[0049] like Figure 7As shown, the rear side of the air intake mesh 310 is connected to the connecting box 320, and the connecting box 320 penetrates the rear side of the adjacent mounting bracket 200. In order to perform vacuum treatment on the connecting box 320, the rear side of the connecting box 320 is fastened to the vacuum pump 330 by bolts.

[0050] like Figure 6 As shown, the input end of the vacuum pump 330 is connected to the output end flange of the vacuum pump 330 through a pipeline; when controlling the operation of the vacuum pump 330, the power range of the vacuum pump 330 is adjusted, and the negative pressure hole 220 is used to limit the negative pressure of the resistor 800.

[0051] The front and rear ends of the inner surface of the negative pressure belt 210 are provided with sealing grooves 211, and the front and rear ends of the vacuum box 300 are integrally formed with sealing elements 311. The sealing elements 311 and the sealing grooves 211 are used together to increase the sealing between the negative pressure belt 210 and the vacuum box 300 when drawing negative pressure; the sealing elements 311 extend into the inner cavity of the adjacent sealing grooves 211.

[0052] The sealing groove 211 and the seal 311 work together to allow the negative pressure belt 210 to slide while preventing air leakage;

[0053] When the sealing element 311 is set, it can form a negative pressure on the end area of ​​the surface of the negative pressure belt 210, while other areas remain at normal pressure, thereby reducing the overall movement resistance of the negative pressure belt 210.

[0054] The conveying assembly also includes a vacuum suction unit 440 for transferring the resistive element 800. The vacuum suction unit 440 is located above the negative pressure belt 210, and an abutment base 500 is provided below the vacuum suction unit 440 and above the negative pressure belt 210. A take-up and release groove 501 is provided on the front side of the surface of the abutment base 500. The take-up and release groove 501 is used in conjunction with the vacuum suction unit 440 to store the vacuum suction unit 440.

[0055] The abutment base 500 is installed at the end of the mounting bracket 200 on the adjacent side.

[0056] To transport the vacuum suction unit 440 so as to convey the resistor 800 provided by the feeding mechanism 110 to the negative pressure belt 210, a telescopic member 2 420 and a telescopic member 1 400 are vertically arranged on the rear side of the vacuum suction unit 440. The telescopic member 2 420 and the telescopic member 1 400 are used together to adjust the longitudinal position and vertical displacement of the vacuum suction unit 440 so that the vacuum suction unit 440 can transport the resistor 800 provided by the feeding mechanism 110 to the middle of the surface of the negative pressure belt 210, and use the negative pressure holes 220 opened on the negative pressure belt 210 to transport the resistor 800 under negative pressure.

[0057] To connect the vacuum suction component 440 with the telescopic component 2 420 and the telescopic component 1 400, the output end of the telescopic component 1 400 is connected to the connecting plate 410 by bolts. The telescopic component 1 400 is installed at the end of the housing 100 and located at the rear of the mounting bracket 200. The telescopic component 2 420 is mounted on the front of the connecting plate 410, and the output end of the telescopic component 2 420 is connected to the mounting plate 430. The vacuum suction component 440 is fastened to the surface of the mounting plate 430 by bolts.

[0058] Multiple detection elements 600 are provided at the end of the abutment base 500. To provide auxiliary support for the detection elements 600, a fixing frame 610 is installed through the surface of the detection element 600. The bottom of the fixing frame 610 is fastened to the end of the abutment base 500 by bolts. The detection elements 600 are used to perform auxiliary detection on the resistivity element 800 during transportation.

[0059] A guide plate 700 is provided on the left side of the end of the mounting bracket 200. A support plate 710 is connected to the front side of the guide plate 700, and the mounting bracket 200 is fastened to the surface of the support plate 710 by bolts. The side of the guide plate 700 away from the support plate 710 is arc-shaped, which can guide the resistors 800 to move towards the center when feeding multiple resistors 800.

[0060] The working principle of a feeding device for a pelletizing machine: The feeding mechanism 110 conveys the resistor 800 to the bottom front side of the telescopic component 400. During this process, the defect identification mechanism 120, in conjunction with the display device 130, performs real-time detection of surface defects on the resistor 800. Subsequently, the vacuum suction component 440, under the linkage of the telescopic component 400 and the telescopic component 420, moves the resistor 800 to the surface of the negative pressure belt 210. At this time, the vacuum pump 330 evacuates the vacuum box 300 through the connecting box 320, so that the air inlet mesh 310 and the negative pressure hole 220 form a negative pressure suction. The resistor 800 is fixed by force, and the drive motor 230 drives the transmission shaft 231 to drive the transmission disc 232 to make the negative pressure belt 210 move in a cycle. With the guidance of the wire disc 240 and the sealing structure of the sealing groove 211 and the sealing element 311, the resistor 800 is stably conveyed to the pelletizing mechanism 140 for processing. The processed material is stored by the material recycling mechanism 150. During the conveying process, the guide plate 700 assists in guiding and correcting the resistor 800, and finally completes the entire process of automatic feeding, detection, conveying, pelletizing and recycling of the resistor 800.
