Description

Technical Field

[0001] The invention relates to the technical field of masterbatch cutting equipment, and in particular to a plastic masterbatch processing device. Background Art

[0002] The full name of masterbatch is plastic masterbatch. It is a kind of plastic processing aid developed in the 1980s. It is composed of excess chemical additives, carrier resins and dispersants. Masterbatch is an aggregate obtained by uniformly loading excess pigments into the resin. Masterbatch refers to the granular material obtained by mixing various required additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then undergoing metering, mixing, melting, extrusion, pelletizing and other processing processes such as extruders. The existing masterbatch processing device usually needs to use a cutting knife to directly cut the plastic strips during granulation.

[0003] The following technical problems exist in the actual use of the masterbatch cutting equipment in the prior art:

[0004] 1. When the existing masterbatch cutting equipment cuts plastic strips into masterbatch, due to the high temperature of the plastic strips, the plastic strips are easily adhered to the cutter or stuck between the cutters during pelletizing, affecting the subsequent pelletizing effect of the plastic strips. Therefore, it needs to be improved.

[0005] 2. At the same time, the tool of the masterbatch cutting equipment is prone to friction and passivation during a long period of time, which makes the tool not sharp when cutting the masterbatch, thus affecting the masterbatch cutting effect, so it needs to be improved. Summary of the invention

[0006] The purpose of the present invention is to solve the above problems and provide a plastic masterbatch processing device.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A plastic masterbatch processing device comprises a chassis, wherein a copper cylinder is movably installed inside the chassis, a groove cylinder located inside the copper cylinder is fixedly installed inside the chassis, an air inlet pipe and an exhaust pipe are fixed inside the chassis, one end of the air inlet pipe is communicated with the groove cylinder, the other end of the air inlet pipe is communicated with an external air cooler, one end of the exhaust pipe is communicated with the space between the groove cylinder and the copper cylinder, and the other end of the exhaust pipe is communicated with an external exhaust device, a track groove is provided inside the groove cylinder, a limit rod is connected to the inner annular equidistant limit sleeve of the track groove, a cutter is fixed to the other end of the limit rod, a through hole corresponding to the cutter is equidistantly provided inside the copper cylinder, a second side plate is fixed to the inner annular equidistant of the copper cylinder, rigid springs are movably sleeved at both ends inside the second side plate, one end of the rigid spring is fixedly connected to a grinding block, a convex rod is fixed to the side of the other end of the rigid spring, and the other end of the convex rod is fixedly connected to the second side plate, and a scraper fixed to the inside of the chassis is movably connected to the outer surface of the copper cylinder.

[0009] Furthermore, a second connecting rod is fixed to the side of the copper cylinder, and the other end of the second connecting rod passes through the chassis and is fixedly connected to a second large gear.

[0010] Furthermore, the outer surface of the second large gear is meshedly connected with the first large gear, a first connecting rod is fixed to the side of the first large gear, the other end of the first connecting rod passes through the chassis and is fixedly connected to a cylinder, and the outer surface of the cylinder is movably connected to the cutter.

[0011] Furthermore, a fixing block is fixed on the side of the chassis, a driving motor is fixedly mounted on the fixing block, a small gear is transmission-connected to the driving motor, and an outer surface of the small gear is meshingly connected with an outer surface of the first large gear.

[0012] Furthermore, a feed inlet is provided inside the upper end of the chassis, and a plastic strip for conveying to the copper cylinder is arranged inside the feed inlet.

[0013] Furthermore, a bottom box is fixed to the bottom of the chassis, and a top opening of the bottom box is larger than a bottom opening.

[0014] Furthermore, brackets are fixed on both sides of the lower end of the bottom box respectively, the number of the brackets is two, and the two brackets have the same size.

[0015] Furthermore, a first side plate is fixed in an annular shape at equal intervals inside the copper cylinder, and a side surface of the first side plate is movably connected to a side surface of the cutter.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. When the copper cylinder rotates, the copper cylinder drives the cutter to rotate through the through-port, and then the limit rod drives the cutter to retract into the copper cylinder through the track groove and the groove of the groove cylinder, so that the cutter scrapes off the cut masterbatch adhered to itself through the through-port, and then the masterbatch adheres to the outer surface of the copper cylinder. At the same time, the cold air fan introduces the cold air flow into the groove cylinder and the copper cylinder through the air inlet pipe, and the cold air flow cools down the masterbatch adhered to the outer surface of the copper cylinder, so that the masterbatch gradually cools down and hardens and does not stick. As the copper cylinder continues to rotate, the scraping block scrapes off the masterbatch adhered to the surface of the copper cylinder, thereby effectively avoiding the phenomenon that the masterbatch is adhered between the cutters and then cuts the masterbatch.

[0018] 2. In the present invention, when the copper cylinder drives the limit rod with the cutter to gradually separate from the groove of the groove cylinder through the first side plate and the grinding block, the track groove gradually pushes the cutter to move to the outside of the through-port through the limit rod, so that the cutting edge of the cutter moving to the outside of the through-port is squeezed onto the grinding block for grinding, and the grinding block is squeezed to move, so that the moving grinding block stretches the convex rod through the rigid spring. At this time, since there is a flowing cold air flow inside the copper cylinder and the scraper block closes the through-port, the cold air flow blows the grinding debris of the cutter to the exhaust pipe for discharge. Such reciprocating operation allows the cutting edge of the cutter to rub the grinding block back and forth for grinding, and the grinding debris is discharged from the exhaust pipe through the cold air flow, thereby achieving the purpose of grinding the cutter when cutting the masterbatch, so that the cutting edge of the cutter is not easy to be blunted and affect the cutting effect.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1, as Figure 1-Figure 8 As shown, a plastic masterbatch processing device includes a chassis 1, a copper cylinder 2 is movably installed inside the chassis 1, a groove cylinder 3 located inside the copper cylinder 2 is fixedly installed inside the chassis 1, an air intake pipe 4 and an exhaust pipe 5 are fixed inside the chassis 1, one end of the air intake pipe 4 is connected to the groove cylinder 3, the other end of the air intake pipe 4 is connected to an external air cooler, one end of the exhaust pipe 5 is connected to the space between the groove cylinder 3 and the copper cylinder 2, the other end of the exhaust pipe 5 is connected to an external exhaust device, a track groove 6 is opened inside the groove cylinder 3, and the inner annular space of the track groove 6 is equidistant The limiting sleeve is connected to the limiting rod 7, and a cutter 8 is fixed to the other end of the limiting rod 7. A through hole 9 corresponding to the cutter 8 is equidistantly opened in the inner ring of the copper cylinder 2. A second side plate 11 is equidistantly fixed to the inner ring of the copper cylinder 2. Rigid springs 14 are movably sleeved at both ends of the second side plate 11. One end of the rigid spring 14 is fixedly connected to the grinding block 12. A convex rod 13 is fixed to the side of the other end of the rigid spring 14. The other end of the convex rod 13 is fixedly connected to the second side plate 11. The outer surface of the copper cylinder 2 is movably connected to a scraper block 15 fixed to the inside of the chassis 1.

[0030] When the copper cylinder 2 rotates, the copper cylinder 2 drives the cutter 8 to rotate through the opening 9, and then the cutter 8 drives the limit rod 7 to rotate along the inside of the track groove 6. At the same time, the air cooler introduces the cold air flow into the groove cylinder 3 through the air inlet pipe 4, so that the cold air flow inside the groove cylinder 3 enters the copper cylinder 2, and the cold air flow cools down the cut plastic masterbatch adhered to the outer surface of the copper cylinder 2, so that the high-temperature adhered masterbatch gradually cools down and hardens and does not stick. After cooling, the gas is discharged from the exhaust pipe 5, and then When the limiting rod 7 rotates to the groove of the groove cylinder 3, the track groove 6 pulls the cutter 8 to shrink into the copper cylinder 2 through the groove and the limiting rod 7, so that the cutter 8 scrapes off the cutting masterbatch adhered to itself through the through opening 9, and then the masterbatch adheres to the outer surface of the copper cylinder 2. As the copper cylinder 2 continues to rotate, the scraping block 15 scrapes off the masterbatch adhered to the surface of the copper cylinder 2, thereby effectively avoiding the phenomenon of the cutter 8 adhering to the masterbatch and then cutting the masterbatch, so that the effect of the cutter 8 cutting the masterbatch is better;

[0031] When the cutter 8 is separated from the passage 9 and retracted into the copper cylinder 2, the copper cylinder 2 will drive the cutter 8 to separate from the passage 9 and rotate to the scraper block 15, so that the scraper block 15 blocks the passage 9, and at the same time, the convex rod 13 will pull the grinding block 12 to fit the blade of the cutter 8 through the rigid spring 14, and then as the copper cylinder 2 continues to rotate, the copper cylinder 2 will drive the cutter 8 to rotate through the grinding block 12, so that the cutter 8 drives the limiting rod 7 to rotate along the inside of the track groove 6, and the limiting rod 7 gradually separates from the groove of the groove cylinder 3, so that the track groove 6 gradually pushes the cutter 8 to move to the outside of the passage 9 through the limiting rod 7. At this time, because the convex rod 13 pulls the grinding block 12 to fit the blade of the cutter 8 through the rigid spring 14, the blade of the cutter 8 moving out of the passage 9 is It is squeezed onto the grinding block 12 for grinding, and the grinding block 12 is squeezed to move, so that the moving grinding block 12 stretches the convex rod 13 through the rigid spring 14. At this time, since there is a flowing cold air flow inside the copper cylinder 2 and the scraper block 15 closes the through port 9, the cold air flow blows the debris ground by the cutter 8 to the exhaust pipe 5 for discharge. As the copper cylinder 2 continues to drive the cutter 8 to rotate through the through port 9, the through port 9 gradually separates from the scraper block 15, and then the cutter 8 passes through the through port 9 and moves to the outside of the copper cylinder 2 to cut the plastic strip. Such reciprocating operation allows the blade of the cutter 8 to reciprocately rub the grinding block 12 for grinding, and the ground debris is discharged from the exhaust pipe 5 through the cold air flow, thereby achieving the purpose of grinding the cutter 8 when cutting the masterbatch, so that the blade of the cutter 8 is not easy to be blunted and affect the cutting effect.

[0033] Through the design of the second connecting rod 19 and the second large gear 20, when the second large gear 20 rotates, the second large gear 20 drives the copper cylinder 2 to rotate as a whole through the second connecting rod 19, so that the copper cylinder 2 can drive the cutter 8 to cut the masterbatch through the through opening 9.

[0034] Furthermore, the outer surface of the second large gear 20 is meshedly connected with the first large gear 18, and a first connecting rod 17 is fixed to the side of the first large gear 18. The other end of the first connecting rod 17 passes through the chassis 1 and is fixedly connected to the cylinder 16, and the outer surface of the cylinder 16 is movably connected to the cutter 8.

[0035] When the copper cylinder 2 rotates, the opening 9 drives the first large gear 18 to rotate through the second large gear 20, and then the first large gear 18 drives the cylinder 16 to rotate through the first connecting rod 17, so that the cylinder 16 and the copper cylinder 2 rotate in opposite directions to quickly transport the plastic strip 25 to the inside of the chassis 1, and the cutter 8 on the copper cylinder 2 cuts the plastic strip 25 into master batches through the cylinder 16.

[0040] Embodiment 4, as Figure 2 As shown, based on the above embodiment, a bottom box 26 is fixed to the bottom of the chassis 1, and the top opening of the bottom box 26 is larger than the bottom opening.

[0041] Through the design of the top and bottom openings of the bottom box 26 , the plastic masterbatch cut by the cutter 8 inside the chassis 1 can fall into the bottom box 26 better, and then be discharged and used in a centralized manner through the bottom opening of the bottom box 26 .
