[0002] Masterbatch is a new type of colorant specifically designed for polymer materials, primarily used in plastics. Composed of three basic elements: pigment or dye, carrier, and additives, masterbatches are aggregates of pigments uniformly loaded onto a resin. This aggregate, known as a pigment concentrate, is a product that possesses a higher tinting power than the pigment itself. During processing, a small amount of masterbatch is blended with uncolored resin to achieve the desired pigment concentration in the colored resin or product. Masterbatches are currently shipped in solid form. To facilitate packaging, storage, and transportation, they are cut into small segments and bagged.

[0027] In addition, the described features, structures or characteristics can be combined in any suitable manner in one or more example embodiments. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure can be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. can be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0028] Example 1

[0029] Refer to the instruction manual Figure 1-3 A plastic masterbatch processing and production equipment according to one embodiment of the present invention includes a base 1, a frame 3 is fixedly provided at the top middle part of the base 1, an extruder 2 fixed to the top of the base 1 is provided on one side of the frame 3, and a cooling and slitting mechanism 4 is provided at the top of the frame 3 corresponding to the discharge port of the extruder 2. The cooling and slitting mechanism 4 consists of a cooling component and a slitting component.

[0030] Furthermore, the cooling assembly includes a hollow support 6 fixedly arranged on the top surface of the frame 3 and an annular tube 7 fixedly embedded in the top of the support 6, with multiple annular cavities 8 provided on the annular tube 7, and multiple groups of air outlets 9 connected to the interior of the annular tube 7 on the inner circumference of each annular cavity 8, and each group of air outlets 9 is provided with two. An air inlet 10 is provided in the middle of the bottom end of the outer circumference of each annular cavity 8, and a through-hole 20 connected to the inner cavity of the support 6 is provided in the middle of the top of the support 6 corresponding to the air inlet 10 of each annular cavity 8. A through-hole 19 connected to the inner cavity of the support 6 is provided at the center position of one side of the support 6, and an air pump 11 is fixedly installed at the position corresponding to the through-hole 19 on the surface of the support 6.

[0031] It should be noted that the ring tube 7 is directly opposite to the discharge end of the extruder 2, and the connecting lines between the center points of the two air outlets 9 of adjacent groups of each section of the ring cavity 8 are arranged in a cross shape to achieve dead-angle-free cooling of the masterbatch. Before starting to extrude the masterbatch, the air pump 11 is first started by an external controller to draw air from the external environment into the interior of the support 6 through the perforation 19, and into the interior of the ring cavity 8 of each section through the perforation 20 and the air inlet 10, and then blown out to the interior of the ring tube 7 through the air outlet 9 at the corresponding position. After normal ventilation, the masterbatch is extruded so that the extruded masterbatch can be quickly cooled and shaped.

[0032] Furthermore, the slitting assembly includes an L-shaped plate 12 fixedly arranged at the edge position of one side of the top of the frame 3, two cylinders 13 are fixedly installed on the inner side of the top end of the L-shaped plate 12 corresponding to the position of the ring tube 7, an arc plate 14 is fixedly installed between the output shaft ends of the two cylinders 13, and a cutter 15 is fixedly provided at the bottom end of the arc plate 14 corresponding to the position between the adjacent segments of the ring cavity 8, and a slitting groove 16 connected to the interior of the ring tube 7 is opened at the top of the outer peripheral surface of the ring tube 7 corresponding to the position of the cutter 15.

[0033] It should be noted that the time interval for the cutter 15 to cut the material can be set according to the discharge speed of the extruder 2, so that the fixed-length masterbatch can be cut each time; the cutter 15 is composed of a vertical part and a semicircular arc part, and the diameter of the semicircular arc part is equal to the inner diameter of the ring tube 7. When the extruded masterbatch reaches a certain length, the cylinder 13 will quickly drive the arc plate 14 to perform a telescopic change, and when the arc plate 14 is extended to the maximum value (that is, the arc plate 14 is in contact with the outer peripheral surface of the ring tube 7), the cutter 15 can cut the masterbatch in this section to obtain masterbatch.

[0034] In this embodiment, a plurality of groups of protruding rods 17 are fixedly provided at positions corresponding to each section of the annular cavity 8 on the inner circumference of the ring tube 7. Each group of protruding rods 17 is provided with a plurality of protruding rods 17, and the protruding rods 17 are evenly distributed in a circular shape along the inner circumference of the ring tube 7. The arrangement of the protruding rods 17 can make the masterbatch entering the interior of the ring tube 7 in a suspended state, which is more conducive to the rapid cooling and shaping of the masterbatch after extrusion.

[0035] Example 2

[0036] Refer to the instruction manual Figure 1 and Figure 4-7 A plastic masterbatch processing and production equipment according to one embodiment of the present invention includes a base 1, a frame 3 is fixedly provided at the top middle part of the base 1, an extruder 2 fixed to the top of the base 1 is provided on one side of the frame 3, and an automatic packaging mechanism 5 is provided on the side of the frame 3 away from the extruder 2. The automatic packaging mechanism 5 is composed of a bag opening component, a sealing and cutting component, and a pushing component.

[0037] Furthermore, the bag opening assembly includes two ear plates 21 that are arranged in parallel and fixedly arranged on the side of the frame 3, a roller 22 is rotatably installed between the ends of the two ear plates 21 on the opposite sides away from the frame 3 through a bearing, a bracket 23 is fixedly provided between the ends of the bottom of the two ear plates 21 away from the frame 3, and a side plate 24 is fixedly provided between the ends close to the frame 3, two cylinders 26 are fixedly provided on the top of the side plate 24 facing the bracket 23, a push plate 1 25 is fixedly provided between the output shaft ends of the two cylinders 26, and two hollow-arranged push plates 25 are fixedly provided on the opposite sides of the push plate 1 25 and the bracket 23. The protrusion 27 is provided, and the opposite sides of the push plate 25 and the protrusion 27 on the bracket 23 are provided with air holes 28 connected to the inner cavity of the protrusion 27. The push plate 25 and the opposite side of the bracket 23 are fixedly provided with air pumps 29. One of the air delivery ends of the two air pumps 29 is connected to the two protrusions 27 at the location thereof. A conduit 30 is provided. A semicircular and inclined guide plate 18 is fixed to the end of the ring tube 7 away from the extruder 2. The lowest point of the guide plate 18 is at the bag opening position after the bag opening is opened, so that the masterbatch pushed out of the ring tube 7 rolls along the guide plate 18 to the inside of the bag.

[0038] It should be noted that the two protrusions 27 on the opposite sides of the push plate 25 and the bracket 23 are arranged in a one-to-one correspondence, so that the open end surface of the protrusion 27 can be in full contact with the surface of the packaging bag and tightly absorb the surface of the packaging bag by means of negative pressure adsorption. In the process of the masterbatch being extruded into the interior of the round tube 7, the cylinder 26 can be controlled by an external controller to push the push plate 1 25 to move toward the bracket 23, so that the open end surface of the protrusion 27 is completely in contact with the surface of the packaging bag, and then the air pump 29 is started to push the protrusion 27 to the outer surface of the packaging bag. The inner cavity of block 27 is evacuated to a negative pressure state, allowing the protrusion 27 to firmly adhere to the surface of the packaging bag, and then the cylinder 2 26 will drive the push plate 1 25 to retreat to a certain position until the bag mouth of the unrolled packaging bag is opened, so that the masterbatch rolling along the guide plate 18 rolls into the interior of the packaging bag. After all the currently cut masterbatch falls into the inside of the opened packaging belt, the air pump 2 29 is used to restore the internal pressure of the protrusion 27 at the corresponding position to the normal pressure state, and the packaging bag containing the masterbatch falls under the action of itself and gravity, and drives the reel 22 to unwind the packaging bag.

[0039] Furthermore, the sealing and cutting assembly includes two cylinder threes 31 fixedly arranged at the bottom end of the side plate 24 facing the bracket 23, a push plate two 32 is fixedly provided between the output shaft ends of the two cylinder threes 31, a cutter two 33 is fixedly provided on the side of the push plate two 32 facing the bracket 23, a cavity 34 is provided at the bottom end of the push plate two 32, a movable bar 35 is slidably connected inside the cavity 34, a spring 36 is fixedly connected between the side of the movable bar 35 away from the bracket 23 and the side where the interior of the cavity 34 is located, a heat sealing head 37 is fixedly installed in the middle of the side of the movable bar 35 facing the bracket 23, and the heat sealing head 37 is movable through the cavity 34 on the side and extends to the outside of the push plate two 32, and a through slot 38 is provided through the position of the cutter two 33 on one side of the bracket 23.

[0040] It should be noted that when the spring 36 is in a natural state, the length of the heat sealing head 37 is greater than the length of the cutter 2 33, and when the heat sealing head 37 retracts inside the net cavity 34 under the action of the bracket 23, the cutter 2 33 will cut the heat-sealed packaging bag. After the packaging bag containing the masterbatch falls to the top of the base 1, the cylinder 31 will push the push plate 2 32 to move toward the bracket 23. During this process, the heat sealing head 37 will first contact the packaging bag containing the masterbatch and push it to the surface of the bracket 23 to complete the heat sealing of the bag opening. As the push plate 2 32 continues to move, the cutter 2 33 will be inserted into the through groove 38 to cut the sealed packaging bag.

[0041] Furthermore, the pushing assembly includes a pressure sensor 39 fixedly embedded in the top of the base 1 at the position corresponding to the winding roller 22, and a mounting plate 40 is fixedly provided at the edge position of one side of the top of the base 1 corresponding to the position of the pressure sensor 39. A cylinder four 41 is fixedly installed in the middle of the side of the mounting plate 40 facing the pressure sensor 39, and an infrared detector 43 is fixedly installed at the top end of the mounting plate 40. The output shaft end of the cylinder four 41 is fixedly connected to the push plate three 42.

[0042] It should be noted that after the pressure sensor 39 detects the gravity signal, it will be transmitted back to the controller, and the controller will control the cylinder three 31 to complete the periodic changes in sequence. Among them, when the pressure sensor 39 detects that the packaging bag containing the masterbatch has fallen to the top of the base 1, and the infrared detector 43 detects that the push plate two 32 has returned to the initial position after the packaging bag is heat-sealed and cut, the controller will control the cylinder four 41 to push the push plate three 42 to push the packaged masterbatch away from the sensing area of the pressure sensor 39 based on the comprehensive signal feedback of the pressure sensor 39 and the infrared detector 43.
