Description

Technical Field

[0001] This utility model relates to the field of extrusion granulators, specifically to a granulation template with a detachable die column. Background Technology

[0002] In the field of plastic and other granulation production, underwater extrusion granulators play a crucial role as one of the mainstream pieces of equipment. The granulation die is a vital component of large-scale extrusion granulation units, and the number of die holes significantly impacts output. Production capacity is typically adjusted based on the product grade and production schedule. However, the number of die holes in existing granulation dies remains fixed after manufacturing. A single specification of granulation die cannot meet production requirements, necessitating the production of multiple specifications, thus increasing production costs. Utility Model Content

[0003] The purpose of this utility model is to provide a granulation template with detachable mold columns. This granulation template can change the number of mold holes by replacing the mold columns with different numbers of mold holes, thereby reducing the manufacturing cost of the granulation template.

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

[0005] A granulation template with detachable mold columns includes a template and several mold columns. The template has several mounting holes arranged in a circular pattern. Each mold column is detachably fixed in each mounting hole. The mold column has several mold holes.

[0006] In the above technical solution, preferably, the mounting hole is stepped, and the outer side of the mold column is stepped and fits the mounting hole.

[0007] In the above technical solution, preferably, the mounting holes are arranged symmetrically on the template, and the mounting holes are evenly distributed on multiple concentric arcs.

[0008] In the above technical solution, preferably, the front opening of the mounting hole is flared.

[0009] In the above technical solution, preferably, the front opening of the mold column is flared.

[0010] In the above technical solution, preferably, the template is provided with a cavity with a circular cross-section, and the cavity is located outside the mounting hole.

[0011] In the above technical solution, preferably, the template is provided with a plurality of fixing holes distributed at equal intervals around the circumference.

[0012] Compared with the prior art, this utility model has the following advantages and effects:

[0013] This invention allows for the detachable fixing of mold columns with die holes onto a template. Therefore, multiple sets of mold columns with different numbers of die holes can be prepared according to production requirements. The number of die holes in the granulation template can be changed by replacing the mold columns, thereby reducing the manufacturing cost of the granulation template. Attached Figure Description

[0020] The components include template 1, mounting hole 11, cavity 12, fixing hole 13, mold column 2, and mold hole 21. Detailed Implementation

[0021] 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.

[0022] See Figures 1-6 This embodiment provides a granulation template with detachable mold columns, including a template 1 and several mold columns 2. The template 1 has several mounting holes 11 arranged in a circular pattern. Each mold column 2 is detachably fixed in each mounting hole 11. The mold column 2 has several mold holes 21.

[0023] This invention detachably fixes the mold column 2 with mold holes 21 onto the template 1. Therefore, multiple sets of mold columns 2 with different numbers of mold holes 21 (such as the commonly used 9-hole and 14-hole) can be prepared according to production requirements. The number of mold holes 21 of the granulation template can be changed by replacing the mold column 2, thereby reducing the manufacturing cost of the granulation template.

[0024] See Figure 1 The front opening of the mounting hole 11 is flared.

[0025] When the granulation template is working, the material enters the mounting hole 11 through the front opening of the mounting hole 11. The flared front opening can guide and compress the material, improve the density uniformity of the material, and thus improve the quality of the plastic granules.

[0026] See Figure 1 , Figure 2 The mounting holes 11 are arranged symmetrically on the template 1, and the mounting holes 11 are evenly distributed on multiple concentric arcs.

[0027] By opening symmetrical and evenly distributed mounting holes 11 on the template 1, the uniformity of the output from the granulation template can be improved, and it is also convenient to cooperate with the rotating cutter head to achieve continuous pelletizing.

[0028] See Figure 1 , Figure 2 The template 1 is provided with a plurality of fixing holes 13 distributed at equal intervals around the circumference.

[0029] The template 1 is fixed to the pelletizer by bolts and fixing holes 13, which improves the stability of the template 1.

[0030] See Figure 3 The template 1 has a cavity 12 with a circular cross-section, which is located outside the mounting hole 11.

[0031] The cavity 12 can reduce the thermal conductivity of the template 1, thereby reducing the risk of solidification caused by excessively rapid cooling of the material in the mounting hole 11 and the mold column 2. The thermal conductivity of the template 1 can be further reduced by evacuating the cavity 12.

[0032] See Figure 4 The front opening of the mold column 2 is flared.

[0033] After the material enters the mounting hole 11, it enters the mold column 2 through the front opening of the mold column 2. The flared front opening can guide the material, reduce the risk of material blockage, and further compress the material to improve the density uniformity of the material.

[0034] See Figure 4 The mounting hole 11 is stepped, and the outer side of the mold column 2 is stepped and fits the mounting hole 11.

[0035] The stepped hole has a limiting function, so the mold column 2 can be installed by inserting it into the stepped hole 11, which improves the convenience of installing and removing the mold column 2.

[0036] 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.
