Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing technology, specifically a pelletizing device for processing color masterbatch for plastic products. Background Technology

[0002] Color masterbatch is a polymeric material colorant specifically used for coloring plastic products. It is made by uniformly dispersing high concentrations of pigments or dyes in a resin carrier. The main equipment for making color masterbatch raw materials into uniform granules is specialized equipment through processes such as extrusion and cutting. The cutting process requires a color masterbatch pelletizing device.

[0003] Chinese Patent Publication No. CN220389989U discloses a pelletizing device for processing color masterbatch in plastic products. The device includes a guide plate, a guide structure mounted on the side wall of the guide plate, a transmission structure mounted on the lower wall of the guide plate, and a pelletizing structure mounted on the upper wall of the guide plate. This invention utilizes the cooperation of a return spring and a cam to achieve repeated pelletizing by moving the pelletizing blade up and down. This allows the pelletizing blade to cut vertically with a double-edged blade, achieving two cuts in one pass, thus improving cutting efficiency. It solves the problem of traditional color masterbatch pelletizing devices having only a single stroke, where the pelletizing blade typically cuts only in one direction, resulting in low cutting efficiency due to a long idle stroke and significant energy consumption. By changing the position of the pelletizing blade on the blade holder, the relative position of the pelletizing blade and the color masterbatch strip can be changed, thereby altering the length of the color masterbatch. The fixed rib plate increases the stability of the two blade holders, reduces vibration during operation, and improves overall stability.

[0004] The above-mentioned device has the function of controlling the length of color masterbatch. However, the temperature of color masterbatch is usually high before the raw material is extruded and pelletized. Long-term use of the blade will cause the blade temperature to be high, which will cause the color masterbatch to stick to the blade, making it difficult for the color masterbatch to fall off and causing it to accumulate. At the same time, the blade is prone to causing the color masterbatch to splatter during the high-speed cutting process. Therefore, it is necessary to provide a pelletizing device for processing color masterbatch for plastic products. Utility Model Content

[0005] The purpose of this invention is to provide a pelletizing device for processing color masterbatch in plastic products, so as to solve the problems of color masterbatch sticking due to blade heating and color masterbatch splashing everywhere when the existing device processes and pelletizes color masterbatch.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pelletizing device for processing color masterbatch of plastic products, comprising a base, a drive motor fixedly installed at the rear of the base, a blade fixedly installed at the output end of the drive motor, and a pellet blowing mechanism provided on the base; the pellet blowing mechanism includes a high-pressure air pump, the high-pressure air pump fixedly installed at the rear of the base, and a shaped tube fixedly installed at the output end of the high-pressure air pump, a plurality of nozzles fixedly installed on the shaped tube, the nozzles having a plurality of spray holes, and a plurality of material guide tubes fixedly installed on the base.

[0007] Preferably, the nozzles are arranged in two arcs, and the circles of the arcs are all located at the output end of the drive motor.

[0008] Preferably, the nozzle is annular in shape, and the feed tube passes through and is tightly attached to the nozzle.

[0009] Preferably, the nozzle is oriented parallel to the feed tube, and the blade is positioned near the front end of the feed tube.

[0010] Preferably, the base is provided with a protective mechanism, which includes a fixed protective seat and a sliding protective seat. The fixed protective seat is fixedly installed on one side of the base, and the sliding protective seat is slidably installed between the base and the fixed protective seat. A transparent plate is fixedly installed on one side of the sliding protective seat, and blocks are fixedly installed on both the upper and lower sides of the base. A buckle is fixedly installed on the upper side of the sliding protective seat.

[0011] Preferably, the protrusions on one side of both the fixed and sliding guards are arc-shaped, and the transparent plate is snap-fitted to the protrusion on one side of the fixed guard.

[0012] Preferably, the sliding guard is provided with protrusions on both the upper and lower sides, and the buckle is matched with the upper side of the fixed guard in a buckling manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The pelletizing device for processing color masterbatch of plastic products is limited by the position of the nozzle, which fixes the contact part between the blade and the raw material. When in use, the high-pressure air pump is controlled to inject high-pressure gas into the shaped tube. The high-pressure gas enters the nozzle and is sprayed onto the blade through the nozzle hole, realizing rapid cooling of the contact part between the blade and the raw material. At the same time, the gas will blow out the cut color masterbatch, thus cooling the color masterbatch while avoiding the accumulation of color masterbatch.

[0014] 2) The pelletizing device for processing masterbatch of plastic products pushes the sliding guard seat to embed the buckle into the fixed guard seat. At this time, the fixed guard seat, the sliding guard seat and the transparent plate form a five-sided enclosed space, allowing the masterbatch to fall from the bottom of the base, thus avoiding the problem of masterbatch splashing. At the same time, the fixed guard seat and the sliding guard seat are connected by a sliding docking method, which makes it easy to open the sliding guard seat to inspect the pelletizing part of the device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0018] Combination Figures 1-3 A pelletizing device for processing color masterbatch of plastic products includes a base 1, a drive motor 2 fixedly installed at the rear of the base 1, a blade 3 fixedly installed at the output end of the drive motor 2, and a pellet blowing mechanism 4 provided on the base 1. The pellet blowing mechanism 4 includes a high-pressure air pump 401, which is fixedly installed at the rear of the base 1, and a special-shaped tube 402 is fixedly installed at the output end of the high-pressure air pump 401. A plurality of nozzles 403 are fixedly installed on the special-shaped tube 402, and a plurality of spray holes 404 are opened on the nozzles 403. A plurality of guide tubes 405 are fixedly installed on the base 1.

[0019] Several nozzles 403 are arranged in two arcs, with the circular arcs all located at the output end of the drive motor 2. Benefiting from the positional relationship of the nozzles 403, when the blade 3 rotates, the nozzles 403 will spray gas through the nozzle holes 404 at the concentrated location of the blade 3, achieving rapid cooling of the blade 3. The nozzles 403 are annular in shape, with the guide tube 405 passing through and closely attached to them. The direction of the nozzle holes 404 is parallel to the guide tube 405. The blade 3 is located near the front end of the guide tube 405. During use, the extruded and cooled strip material is pushed out at a constant speed through the feed tube 405. Benefiting from the position of the nozzle 403, the contact part between the blade 3 and the material is fixed. The high-pressure air pump 401 is further controlled to inject high-pressure gas into the shaped tube 402, so that the high-pressure gas enters the nozzle 403 and is sprayed onto the blade through the nozzle 404, thereby achieving rapid cooling of the contact part between the blade 3 and the material. At the same time, the gas blows out the cut masterbatch, thereby cooling the masterbatch and preventing its accumulation. Example 2

[0020] See Figure 4 and Figure 5 The base 1 is provided with a protective mechanism 5, which includes a fixed protective seat 501 and a sliding protective seat 502. The fixed protective seat 501 is fixedly installed on one side of the base 1, and the sliding protective seat 502 is slidably installed between the base 1 and the fixed protective seat 501. A transparent plate 503 is fixedly installed on one side of the sliding protective seat 502. Blocks 504 are fixedly installed on both the upper and lower sides of the base 1, and a buckle 505 is fixedly installed on the upper side of the sliding protective seat 502.

[0021] The protrusions on one side of both the fixed guard 501 and the sliding guard 502 are arc-shaped, which helps guide the masterbatch to fall from the bottom of the base 1. The transparent plate 503 is matched with the protrusion on one side of the fixed guard 501. When the fixed guard 501 and the sliding guard 502 are connected, the transparent plate 503 achieves the effect of preventing splashing and facilitating observation. The upper and lower sides of the sliding guard 502 are provided with protrusions. The buckle 505 is matched with the upper side of the fixed guard 501, so that the fixed guard 501 and the sliding guard 502 are connected through the buckle 505.

[0022] In actual operation, the position of the nozzle 403 limits the contact area between the blade 3 and the raw material. When in use, the high-pressure air pump 401 is controlled to inject high-pressure gas into the shaped tube 402, so that the high-pressure gas enters the nozzle 403 and is sprayed onto the blade 3 through the nozzle 404, thereby achieving rapid cooling of the contact area between the blade 3 and the raw material. At the same time, the gas blows out the cut masterbatch, thus cooling the masterbatch while preventing it from accumulating. By pushing the sliding guard 502, the buckle 505 is embedded in the fixed guard 501. At this time, the fixed guard 501, the sliding guard 502 and the transparent plate 503 form a five-sided enclosed space, allowing the masterbatch to fall from the bottom of the base 1, thus avoiding the problem of masterbatch splashing. At the same time, the fixed guard 501 and the sliding guard 502 are connected by a sliding docking method, which makes it easy to open the sliding guard 502 to inspect the pelletizing part of the device.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
