Description
Technical Field
[0001] The invention relates to the technical field of plastic molding, and in particular to an anti-adhesion masterbatch pelletizer. Background Art
[0002] Masterbatch is a synthetic resin carrier with a high proportion of additives such as pigments and dispersants added. After physical blending, melt mixing, dispersion, and extrusion, the masterbatch pelletizing operation is completed by a pelletizer. The extruded masterbatch strips are guided by guide rollers and directly transported into the pelletizer for pelletizing by a cutter. Due to the raw material and mixing problems, the extruded masterbatch strips have protruding edges on the surface of the masterbatch strips. The protruding parts of the masterbatch edges are transported to the pelletizer along with the masterbatch strips as a whole. It is impossible to process the protruding surfaces of the masterbatch strips before they enter the pelletizer, which makes it easy for the masterbatch strips to have tailing problems when they enter the pelletizer for masterbatch pelletizing, resulting in adhesion before and after the masterbatch pelletizing. At the same time, the extruded masterbatch strips are dried during the transportation process to reduce the wetness. Because the transportation distance causes the temperature of the masterbatch strips to drop, which affects the viscosity of the masterbatch strips. The masterbatch strips cannot be pre-treated before entering the pelletizer for pelletizing, which makes it easy for the masterbatch strips to stick together during pelletizing, affecting the pelletizing effect of the masterbatch and the operating efficiency. Summary of the invention
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-sticking masterbatch pelletizer, which guides the conveyed masterbatch strips to enter the interior of the masterbatch strip compacting and trimming module by setting a guide roller, and the four compacting plates cover various areas of the masterbatch strip surface to completely perform surface treatment on the passing masterbatch strips, effectively trim the edge protrusions in various areas of the masterbatch surface, and allow the surface-treated masterbatch strips to continue to be conveyed to the heat treatment constraint module in the rear position, and multiple constraint heat pipes perform multi-area and long-term heat treatment on the conveyed masterbatch strips, effectively pre-treating the masterbatch strips before pelletizing, avoiding tailing and adhesion when pelletizing the masterbatch, and the masterbatch strips are separated from the crimping module to separate and lift the masterbatch strips from the top of the pelletizer base, and the arc-shaped end pressure shell follows the movement of the cutter to press down and constrain the masterbatch strips, so that the cutter can stably cut the masterbatch strips at a fixed point, thereby improving the pelletizing effect of the masterbatch, so as to solve the problems raised in the above-mentioned background technology.

[0023] The pelletizer base 1 is used to connect the pelletizer drive 11, the masterbatch strip pressing and trimming module 2, the heat treatment constraint module 3 and the masterbatch strip disengagement and crimping module 4. The pelletizer drive 11 is fixed on the top of the pelletizer base 1, and the cutter 12 is fixed on the output end of the pelletizer drive 11 to stably position the cutter 12 in the designated pelletizing area on the top of the pelletizer base 1.

The lower guide roller 131 is located between the masterbatch strip pressing and trimming module 2 and the heat treatment constraint module 3, and the higher guide roller 131 is located inside the constraint shell 31. The higher guide roller 131 cooperates with the lower guide roller 131 to stably guide and convey the masterbatch strips.
[0025] The inner side of the positioning outer frame 21 is engaged with four combined inner shells 22, and the inner side of the combined inner shell 22 is rotatably connected to four pressing plates 23, so that the combined inner shell 22 can move with the corresponding four pressing plates 23 on the inner side of the positioning outer frame 21, so as to quickly place and remove the combined inner shell 22 and the pressing plates 23 inside the positioning outer frame 21. A rotating rod 231 is fixedly connected inside the pressing plate 23, and the other end of the rotating rod 231 is rotatably connected to the inner wall of the combined inner shell 22, and the pressing plates 23 are rotated inside the combined inner shell 22 through the rotating rod 231. The four pressing plates 23 are distributed in an annular manner on the outer side of the masterbatch strip, so that the four pressing plates 23 can cover various areas of the surface of the masterbatch strip from the outside, and the pressing plates 23 are close to the surface of the masterbatch strip, so that the four pressing plates 23 can cooperate to completely perform surface treatment on the masterbatch strip passing through, effectively repair the edge protrusions existing in various areas of the masterbatch surface, and allow the masterbatch strip that has been surface treated to continue to be transported to the heat treatment constraint module 3 at the rear position.

[0026] There are four heating drive members 32, and the four heating drive members 32 are fixedly connected to the inner wall of the restraining shell 31 in sequence, and the restraining heat pipe 33 is fixedly connected to the output end of the heating drive member 32, so that the four heating drive members 32 are positioned above the corresponding masterbatch strips through the restraining shell 31. The restraining heat pipe 33 is positioned outside the conveyed masterbatch strip, and multiple restraining heat pipes 33 are respectively positioned in different areas outside the masterbatch strip to effectively cover different positions of the masterbatch strip, so as to continuously heat treat the conveyed masterbatch strip from different areas, heat the masterbatch strip and keep the masterbatch strip at a specified temperature to approach the cutter 12. A heating space 34 is formed between the restraining shell 31 and the front bracket 13, so that the masterbatch strip enters the heating space 34 for heat treatment after the masterbatch strip is pressed against the surface of the finishing module 2 for treatment.
[0027] The masterbatch strip disengagement crimping module 4 is arranged at the top of the pelletizer base 1. The masterbatch strip disengagement crimping module 4 is composed of a pressure bar 41, a support bar 42 and an arc-shaped end pressure shell 43. The support bar 42 is fixedly connected to the top of the pelletizer base 1. The pressure bar 41 is screwed on the top of the support bar 42. The pressure bar 41 approaches the support bar 42 from above the support bar 42, and the pressure bar 41 can be stably fastened to the top of the support bar 42. The masterbatch strip first enters the corresponding groove at the top of the support bar 42, and the pressure bar 41 is fastened to the top of the support bar 42. The pressure bar 41 cooperates with the support bar 42 to hold up the masterbatch strip, and presses down the entered masterbatch strip, so that the masterbatch strip always moves on the inner side of the masterbatch strip disengagement crimping module 4, and at the same time, the masterbatch strip is separated from the top of the pelletizer base 1, so that the masterbatch strip is stably and smoothly transported to the cutter 12, ensuring smooth transportation and pelletizing of the masterbatch strip. The length of the support row 42 is smaller than the length of the pressure row 41, and the front end of the pressure row 41 is flush with the front end of the support row 42. When the masterbatch strip is close to the cutter 12, the constraint of the masterbatch strip is released to ensure that the arc-shaped end pressure shell 43 in the rear position works normally. There are four arc-shaped end pressure shells 43, which are engaged at the rear end of the pressure row 41. A fixed block 431 is fixedly connected to the top of the arc-shaped end pressure shell 43, and the fixed block 431 is fixedly connected to the surface of the cutter 12, so that the arc-shaped end pressure shell 43 is stably connected to the surface of the cutter 12, so that the four arc-shaped end pressure shells 43 correspond to the four corresponding grooves on the pressure row 41 and the four masterbatch strips, so that the arc-shaped end pressure shell 43 can effectively follow the cutter 12 to move above the masterbatch strip, so as to press down the masterbatch strip through the arc-shaped end pressure shell 43 to ensure that the cutter 12 cuts the masterbatch strip at a fixed point.
[0028] The front bracket 13 positions the masterbatch strip pressing and trimming module 2 and the heat treatment constraint module 3 in front of the pelletizer base 1. The two guide rollers 131 guide the conveying masterbatch strip to move toward the top of the pelletizer base 1, allowing the masterbatch strip to approach the cutter 12. The masterbatch strip is led out from the inside of the masterbatch strip pressing and trimming module 2 at a lower position to the guide roller 131 at a lower position. The four pressing plates 23 cover various areas on the surface of the masterbatch strip. The pressing plates 23 rotate against the surface of the masterbatch strip when the masterbatch strip passes, so that the pressing plates 23 continuously press the surface of the masterbatch strip from the outside, and can trim the protrusions of the masterbatch on the surface of the masterbatch strip. The four pressing plates 23 can completely perform surface treatment on the passing masterbatch strip to effectively trim the edge protrusions in various areas of the masterbatch surface. The masterbatch strips after surface treatment continue to be transported to the heat treatment constraint module 3 in the rear position. The constraint heat pipe 33 is positioned on the outside of the masterbatch strip through the heating drive 32. Multiple constraint heat pipes 33 are positioned in different areas on the inside of the constraint shell 31 to cover different positions of the masterbatch strips respectively, which can effectively perform multi-area and long-term heat treatment on the transported masterbatch strips, so that the masterbatch strips are kept at a specified temperature to be close to the cutter 12. The masterbatch strip pressing and finishing module 2 cooperates with the heat treatment constraint module 3 to effectively perform surface finishing and heat treatment on the masterbatch strips, achieving the effect of pre-treating the masterbatch strips before the masterbatch strips enter the pelletizing drive 11 for pelletizing, so as to effectively avoid tailing and adhesion when the masterbatch is pelletized. At the same time, the pressure row 41 and the support row 42 positioned on the top of the pelletizer base 1 cooperate to separate and lift the masterbatch strips from the top of the pelletizer base 1, so that the masterbatch strips can be stably and smoothly transported to the cutter 12. The arc-shaped end pressure shell 43 moves with the cutter 12 to approach the corresponding masterbatch strip being conveyed. The arc-shaped end pressure shell 43 can press down to constrain the masterbatch strip, allowing the cutter 12 to stably cut the masterbatch strip at a fixed point, thereby improving the pelletizing effect of the masterbatch and improving the working efficiency.
[0029] The working principle of the present invention is as follows: the masterbatch strip is led out from the inside of the masterbatch strip pressing and finishing module 2 at a lower position to the guide roller 131 at a lower position, and four pressing plates 23 cover various areas on the surface of the masterbatch strip. The pressing plates 23 rotate close to the surface of the masterbatch strip when the masterbatch strip passes through, and continuously press the surface of the masterbatch strip from the outside to perform finishing treatment on the protrusions of the masterbatch strip on the surface of the masterbatch strip. The masterbatch strip after surface treatment continues to be transported to the heat treatment constraint module 3 at the rear position, and the masterbatch strip enters the interior of the heating space 34, and the masterbatch strip enters the interior of the constraint heat pipe 33 and continues to be transported inside the constraint heat pipe 33. Multiple constraint heat pipes 33 cover different positions of the masterbatch strip to control the transport The delivered masterbatch strips are subjected to multi-zone and long-term heat treatment, so that the masterbatch strips are kept at the specified temperature and escape from the heating space 34, and the escaped masterbatch strips enter the corresponding grooves between the pressure row 41 and the support row 42, and the pressure row 41 and the support row 42 cooperate to separate and lift the masterbatch strips from the top of the pelletizer base 1, so that the masterbatch strips are stably and smoothly conveyed to the cutter 12, and the pelletizing drive 11 starts to control the movement of the cutter 12, and the arc-shaped end pressure shell 43 follows the movement of the cutter 12 to approach the corresponding conveyed masterbatch strips, and the arc-shaped end pressure shell 43 presses down to constrain the masterbatch strips, so that the cutter 12 can stably cut the masterbatch strips at a fixed point, and the pelletized masterbatch is discharged outward from the top of the pelletizer base 1.
