Description

Technical Field

[0001] This utility model relates to the technical field of resin processing, and in particular to a resin pelletizing device. Background Technology

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broader sense, any polymer compound that can be used as a raw material for processing plastic products can be called a resin.

[0003] In the modification or recycling granulation process of resins (such as plastics and rubber), it is usually necessary to continuously cut the strip-shaped resin output from the extruder into uniformly sized granules to facilitate subsequent transportation and processing. This cutting process is generally completed by a pelletizing device, which relies on high-speed rotating blades to cut the resin. However, in practical applications, the feeding drive component and the cutting drive component of existing pelletizing devices are usually designed as independent separate components. Therefore, during the cutting process, the cutting efficiency and feeding speed need to be adjusted according to the size of the granules. During the adjustment process, it is necessary to ensure that the cutting speed and the feeding speed are matched; otherwise, uneven granulation will occur. This adjustment process is not only time-consuming and affects the overall pelletizing efficiency, but also increases the overall manufacturing cost of the device due to the need for an additional independent feeding drive component. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one objective of this utility model is to provide a resin pelletizing device that can maintain the synchronization of cutting rate and feeding rate during the pelletizing process, thereby eliminating the need for manual adjustment and effectively improving pelletizing efficiency; at the same time, it saves the additional cost of an independent feeding drive component, which helps to reduce the overall manufacturing cost of the pelletizing device.

[0006] To achieve the above objectives, this utility model proposes a resin pelletizing device, comprising a support assembly, a cutting assembly, and a transmission mechanism. The cutting assembly is mounted on the support assembly and includes a drive motor, a transmission rod, and a cutter. The drive motor is mounted on the support assembly, and the cutter is connected to the output end of the drive motor via the transmission rod, contacting the discharge end of the support assembly. The transmission mechanism is mounted on the support assembly and includes a rotating rod, a first linkage assembly, a second linkage assembly, and an extrusion plate. The rotating rod is mounted on the support assembly and is connected to the cutting assembly via the first linkage assembly. The extrusion plate is connected to the second linkage assembly and faces the support assembly, and is connected to the rotating rod via the second linkage assembly.

[0007] In addition, the resin pelletizing apparatus proposed in the application may also have the following additional technical features:

[0008] Specifically, the first linkage component includes a first driving sprocket, a first driven sprocket, and a first chain, wherein the first driving sprocket is mounted on the transmission rod, the first driven sprocket is mounted on the rotating rod, and the first driving sprocket is connected to the first driven sprocket via the first chain.

[0009] Specifically, the second linkage component includes a second chain, a second driving sprocket, a second driven sprocket, and a threaded rod. The second driving sprocket is mounted on the rotating rod, and the second driven sprocket is rotatably mounted on the support component. The second driving sprocket is connected to the second driven sprocket via the second chain. The threaded rod is threaded through the second driven sprocket and the support component, and one end of the threaded rod is rotatably connected to the extrusion plate.

[0010] Specifically, the support assembly includes a support frame, a support plate, an extrusion cylinder, and a granulation plate, wherein the extrusion cylinder is mounted on the support frame via the support plate, and the granulation plate is mounted on the discharge end of the extrusion cylinder.

[0011] Specifically, a feed valve is connected to the extrusion cylinder.

[0012] The resin pelletizing device of this invention can cut the extruded resin through a cutting component during the pelletizing process, and drive the extrusion plate through a transmission mechanism during the cutting process, thereby achieving synchronous extrusion, ensuring the consistency of cutting progress and feeding progress, eliminating the need for manual adjustment, and effectively improving pelletizing efficiency; at the same time, by reducing independent feeding drive components, it helps to reduce the overall manufacturing cost of the pelletizing device.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The resin pelletizing device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0021] The resin pelletizing device provided in this embodiment can be used for pelletizing resin. During the pelletizing process, the cutting rate and the feeding rate can be kept synchronized, thereby eliminating the need for manual adjustment and effectively improving pelletizing efficiency. At the same time, it saves the additional cost of an independent feeding drive component, which helps to reduce the overall manufacturing cost of the pelletizing device.

[0022] like Figures 1-3As shown, the resin pelletizing device of this utility model embodiment may include a support component 1, a cutting component 2, and a transmission mechanism 3.

[0023] It should be noted that the support component 1 described in the above embodiment is connected to a water inlet pipe, thereby cooling the cut resin particles.

[0024] The cutting component 2 is mounted on the support component 1 and may include a drive motor 21, a transmission rod 22, and a cutter 23.

[0025] It should be noted that the cutter 23 described in the above embodiment is provided in two sets, and the cutter 23 is in contact with the discharge end of the support component 1.

[0026] The drive motor 21 is mounted on the support assembly 1, and the cutter 23 is connected to the output end of the drive motor 21 via the transmission rod 22. The cutter 23 is in contact with the discharge end of the support assembly 1.

[0027] Understandably, the drive motor 21 drives the cutter 23 through the transmission rod 22, and the cutter 23 cuts the extruded resin during its rotation.

[0028] The transmission mechanism 3 is mounted on the support assembly 1. The transmission mechanism 3 may include a rotating rod 31, a first linkage assembly 32, a second linkage assembly 33, and a pressing plate 34.

[0029] It should be noted that the rotating rod 31, the first linkage component 32, and the second linkage component 33 described in the above embodiments are all provided in two sets.

[0030] The rotating rod 31 is mounted on the support assembly 1. The rotating rod 31 is connected to the cutting assembly 2 through the first linkage assembly 32. The extrusion plate 34 is connected to the second linkage assembly 33 and is positioned facing the support assembly 1. The extrusion plate 34 is connected to the rotating rod 31 through the second linkage assembly 33.

[0031] Understandably, under the action of the first linkage component 32, the rotating rod 31 is driven by the cutting component 2, and then the rotating rod 31 drives the second linkage component 33 to rotate synchronously, thereby driving the extrusion plate 34 through the second linkage component 33, and realizing the extrusion of the molten resin in the support component 1.

[0032] Specifically, such as Figure 3 As shown, the first linkage component 32 may include a first driving sprocket 321, a first driven sprocket 322 and a first chain 323.

[0033] The first driving sprocket 321 is mounted on the transmission rod 22, and the first driven sprocket 322 is mounted on the rotating rod 31. The first driving sprocket 321 is connected to the first driven sprocket 322 through the first chain 323.

[0034] It is understandable that when the first driving sprocket 321 rotates with the transmission rod 22, the first driving sprocket 321 drives the first driven sprocket 322 through the first chain 323, thereby driving the rotating rod 31 through the first driven sprocket 322.

[0035] Specifically, such as Figure 3 As shown, the second linkage component 33 may include a second chain 331, a second drive sprocket 332, a second driven sprocket 333, and a threaded rod 334.

[0036] It should be noted that the second driven sprocket 333 described in the above embodiment has a thread inside that matches the threaded rod 334, thereby facilitating the driving of the threaded rod 334.

[0037] The second driving sprocket 332 is mounted on the rotating rod 31, and the second driven sprocket 333 is rotatably mounted on the support assembly 1. The second driving sprocket 332 is connected to the second driven sprocket 333 via the second chain 331. The threaded rod 334 is threaded through the second driven sprocket 333 and the support assembly 1, and one end of the threaded rod 334 is rotatably connected to the extrusion plate 34.

[0038] It is understandable that after the second driving sprocket 332 is driven by the rotating rod 31, it drives the second driven sprocket 333 to rotate through the second chain 331. Under the action of the internal thread of the second driven sprocket 333, the extrusion plate 34 is driven, thereby realizing the extrusion of resin in the support assembly 1.

[0039] Specifically, in actual operation, the personnel first place the resin material to be granulated into the support assembly 1, and then start the drive motor 21 of the cutting assembly 2. The drive motor 21 drives the cutter 23 to rotate at high speed through the transmission rod 22. At this time, the cutter 23 contacts the discharge end of the support assembly 1 to achieve resin cutting. During the cutting process, the first drive sprocket 321 on the transmission rod 22 drives the first driven sprocket 322 to rotate through the first chain 323, which in turn drives the rotating rod 31 to rotate. The second drive sprockets 332 at both ends of the rotating rod 31 drive the second driven sprockets 333 to rotate synchronously through the second chain 331. Since the second driven sprocket 333 has a threaded hole inside that matches the threaded rod 334, under the action of threaded transmission, the threaded rod 334 pushes the extrusion plate 34 to move towards the support assembly 1, so that the extrusion plate 34 generates continuous pressure on the resin in the cylinder. The pressure is linked to the cutting action of the cutter 23. After the cutter 23 completes a single cut, the extrusion plate 34 pushes the subsequent resin to the cutting position. By adjusting the thread pitch of the second driven sprocket 333 and the threaded rod 334, the synchronization ratio between the resin pushing speed and the cutting frequency can be precisely controlled. The entire process requires no manual intervention in the feeding speed, and the cutting and extrusion functions are achieved simultaneously by the drive motor 21. Compared with the traditional design that requires an independent feeding drive device, this reduces the number of power sources and lowers the equipment failure rate.

[0040] The above-described embodiments can maintain synchronization between the cutting rate and the feeding rate during the pelletizing process, thereby eliminating the need for manual adjustment and effectively improving pelletizing efficiency; at the same time, it saves the additional cost of an independent feeding drive component, which helps to reduce the overall manufacturing cost of the pelletizing device.

[0041] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the support assembly 1 may include a support frame 11, a support plate 12, an extrusion cylinder 13, and a granulation plate 14.

[0042] It should be noted that the support frame 11 described in the above embodiment has a cooling chamber inside it under the action of the support plate 12, thereby realizing the cooling of the resin after cutting and facilitating the rapid molding of resin particles.

[0043] The extrusion cylinder 13 is mounted on the support frame 11 via the support plate 12, and the granulation plate 14 is mounted on the discharge end of the extrusion cylinder 13.

[0044] Understandably, the resin is placed under the action of the extrusion cylinder 13, and then the resin is extruded into granules and discharged under the action of the granulation plate 14.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, a feed valve is connected to the extrusion cylinder 13.

[0046] Understandably, the discharge valve facilitates direct connection of the extrusion cylinder 13 to the extruder (not shown in the figure), thereby facilitating the discharge of the melted resin and preventing the resin from being discharged from the top of the extrusion cylinder 13 during the extrusion process.

[0047] In summary, the resin pelletizing device of this utility model can maintain the synchronization of cutting rate and feeding rate during the pelletizing process, thereby eliminating the need for manual adjustment and effectively improving pelletizing efficiency; at the same time, it saves the additional cost of adding an independent feeding drive component, which helps to reduce the overall manufacturing cost of the pelletizing device.
