Description

Technical Field

[0001] This utility model relates to the field of pelletizing disc structure, specifically to a composite pelletizing disc of cutter and disc. Background Technology

[0002] In large-scale extrusion pelletizing systems, the pelletizer blades and cutter discs are crucial core components of the pelletizer, often requiring a precise assembly process—that is, accurately installing the pelletizer blades onto the cutter disc. This assembly process sets extremely strict standards for the manufacturing and assembly precision of the pelletizer blades and cutter discs, demanding not only highly skilled installation technicians but also a considerable amount of installation time, thus impacting production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a composite pelletizing disc that combines a cutter and a disc. This pelletizing disc reduces the skill requirements of installers by integrating the pelletizer and the disc, while also reducing the installation time of the pelletizer and disc, thereby improving production efficiency.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A composite pelletizing disc with a cutter and a disc includes an integral pelletizing blade and a disc, wherein multiple pelletizing blades are arranged on the disc at equal intervals around the circumference.

[0006] In the above technical solution, preferably, the number of pelletizing blades is set to five.

[0007] In the above technical solution, preferably, a strip of wear-resistant alloy is welded to the front edge of the pelletizing blade.

[0008] In the above technical solution, preferably, a mounting hole is provided in the middle position of the cutter head, and a limit groove is provided on the side of the mounting hole.

[0009] In the above technical solution, preferably, both the pelletizing blade and the cutting disc are made of stainless steel.

[0010] In the above technical solution, preferably, the plane where the front end of the pelletizer is located protrudes forward relative to the front side of the cutter disc.

[0011] Compared with the prior art, this utility model has the following advantages and effects:

[0012] This invention integrates the pelletizer blade onto the cutter disc, eliminating the need to install the blade onto the disc separately. The dimensional parameters of both the pelletizer blade and the cutter disc can be precisely controlled through machining, facilitating compliance with production standards. Compared to manufacturing the pelletizer blade and cutter disc separately and then assembling them, this invention reduces the skill requirements for installers, lowers labor training costs, and shortens the installation time of the pelletizer blade and cutter disc, thereby improving production efficiency.

[0017] Among them, there is a pelletizing blade 1, a wear-resistant alloy 11, a blade disc 2, a mounting hole 21, and a limiting groove 22. Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] See Figures 1-4 This embodiment provides a composite pelletizing disc consisting of a cutting blade and a disc, comprising an integral pelletizing blade 1 and a disc 2. The pelletizing blades 1 are arranged in multiples and are distributed circumferentially at equal intervals on the disc 2.

[0020] This invention integrates the pelletizer 1 onto the cutter disc 2, eliminating the need to install the pelletizer 1 onto the cutter disc 2. The pelletizer 1 and the cutter disc 2 can be precisely controlled in terms of dimensional parameters through machining, making it easier to meet production standards. Compared to manufacturing the pelletizer 1 and the cutter disc 2 separately and then assembling them, this invention reduces the skill requirements for installers, lowers labor training costs, and reduces the installation time of the pelletizer 1 onto the cutter disc 2, thereby improving production efficiency.

[0021] See Figure 1 The number of pelletizing blades 1 is set to five.

[0022] The number of pelletizing blades 1 can be adjusted according to production capacity requirements. When there are five pelletizing blades 1, it is possible to simultaneously meet certain production capacity requirements and reduce the overall weight of the pelletizing blades 1 and the cutting disc 2, thereby reducing the energy consumption for driving the cutting disc 2 to rotate.

[0023] See Figure 1 , Figure 2 The front edge of the pelletizer 1 is welded with a strip of wear-resistant alloy 11.

[0024] In this invention, the wear-resistant alloy 11 is Stellite alloy, and the front and rear thickness of the wear-resistant alloy 11 is greater than or equal to 2mm. It has good wear resistance, which can reduce the wear rate of the pelletizer 1 during the pelletizing process and extend the service life of the pelletizer 1.

[0025] See Figure 3 The cutter head 2 has a mounting hole 21 in the middle position, and a limit groove 22 is provided on the side of the mounting hole 21.

[0026] Mounting hole 21 is used to fit onto the drive shaft of the granulator to drive the rotation of the cutter head 2. The limiting groove 22 cooperates with the protrusion on the drive shaft during installation to play a positioning role. At the same time, it can enable the cutter head 2 to be driven to rotate by the drive shaft, improving the stability of the connection between the drive shaft and the cutter head 2.

[0027] Both the pelletizing blade 1 and the cutting disc 2 are made of stainless steel.

[0028] Since the pelletizing blade 1 and the cutting disc 2 are usually used for pelletizing underwater, the use of stainless steel for the pelletizing blade 1 and the cutting disc 2 provides good corrosion resistance and high mechanical strength, thereby improving the service life of the pelletizing blade 1 and the cutting disc 2.

[0029] See Figure 1 , Figure 2 The plane at the front end of the pelletizer 1 protrudes forward relative to the front side of the cutter disc 2.

[0030] When the pelletizer 1 rotates, it needs to fit in close contact with the pelletizing template to achieve the pelletizing effect. At this time, the front side of the cutter head 2 does not contact the pelletizing template, thereby reducing the resistance encountered when the cutter head 2 rotates, reducing the energy consumption to drive the cutter head 2 to rotate and the wear rate of the cutter head 2.

[0031] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
