Description

Technical Field

[0001] This utility model relates to the field of color masterbatch machine technology, and in particular to a color masterbatch machine color masterbatch dispensing system. Background Technology

[0002] A color masterbatch machine is an indispensable piece of equipment in injection molding production. It can dispense and mix raw materials and color masterbatch according to the weight set in the process formula menu to obtain the required color depth.

[0003] Existing color masterbatch machines (such as the weighing-type color masterbatch machine disclosed in application number 201610588420.5) consist of a base, a mixing mechanism, a main material feeding system, and a color masterbatch feeding system. The main material feeding system feeds a preset weight of main material into the cavity of the base, and the color masterbatch feeding system feeds a preset weight of color masterbatch into the cavity of the base. The mixing mechanism mixes the main material and color masterbatch in the cavity to form a mixture, which is then discharged through the outlet on the base. Because color masterbatch is prone to impurities, and the color masterbatch feeding system cannot screen these impurities, they are fed into the cavity of the base along with the color masterbatch, affecting the subsequent injection molding effect. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a masterbatch filling system for a masterbatch machine. This system solves the technical problem that the existing masterbatch filling system cannot screen impurities in the masterbatch, and the impurities are added into the cavity of the base along with the masterbatch, which will affect the subsequent injection molding effect.

[0005] To achieve the above technical objectives, the present invention provides a masterbatch dispensing system for a masterbatch machine, comprising: A masterbatch hopper has a storage chamber, an impurity chamber and a masterbatch chamber. The masterbatch hopper is provided with a screening port that connects the storage chamber and the impurity chamber. The masterbatch hopper is also provided with an overflow port that connects the storage chamber and the masterbatch chamber. The overflow port can be closed. A screening mechanism includes a screening element and a screening drive assembly. The screening element is sealed at the screening port. The screening drive assembly is connected to the screening element and is used to drive the screening element to screen the masterbatch in the storage chamber and cause the screened impurities to fall into the impurity chamber.

[0006] Furthermore, the masterbatch hopper includes a masterbatch box and an impurity trough. The impurity trough is fixed inside the masterbatch box. The space above the impurity trough forms the storage cavity. The impurity cavity is formed inside the impurity trough. The space below the impurity trough forms the masterbatch cavity. The opening at the top of the impurity trough forms the screening port. The two corresponding long sidewalls of the impurity trough and the two corresponding inner sidewalls of the masterbatch box are spaced one-to-one to form two flow ports.

[0007] Furthermore, the screening component is a screening cylinder, which is rotatably and sealed at the screening port. The screening drive assembly is connected to the screening cylinder and is used to drive the screening cylinder to rotate. During the rotation of the screening cylinder, the masterbatch in the storage chamber can be screened, and the screened impurities can fall into the impurity chamber.

[0008] Furthermore, the screening component includes a main shaft, a frame, and a screen. The two ends of the main shaft are rotatably connected to the color masterbatch hopper. The frame is a cylindrical structure and coaxially covers the outer wall of the main shaft. The screen is laid on the arc-shaped wall of the frame. The screening drive assembly is connected to the main shaft and is used to drive the main shaft to rotate.

[0009] Furthermore, the screening drive assembly includes a first rotation drive component, the output end of which is detachably and coaxially fixedly connected to one end of the main shaft.

[0010] Furthermore, the side wall of the color masterbatch hopper is provided with an installation port, which corresponds to the screening cylinder, and the diameter of the installation port is equal to or greater than the diameter of the screening cylinder. The color masterbatch hopper also includes a cover plate, which is detachably placed on the installation port to block it.

[0011] Furthermore, the masterbatch filling system of the masterbatch machine also includes a first opening and closing mechanism. The first opening and closing mechanism includes a first opening and closing plate and a first driving component. The first opening and closing plate is disposed at the flow port. The first driving component is connected to the first opening and closing plate and is used to drive the first opening and closing plate to move so that the first opening and closing plate moves closer to or further away from the flow port and puts the flow port in an open or closed state.

[0012] Furthermore, one side of the first opening and closing plate is rotatably connected to the color masterbatch hopper. The first driving assembly includes a first connecting rod and a first telescopic driving member. One end of the first connecting rod is fixedly connected to the rotation shaft of the first opening and closing plate. The output end of the first telescopic driving member is hinged to the other end of the first connecting rod, which is used to drive the first connecting rod to swing back and forth, so that the first opening and closing plate swings back and forth around its own rotation shaft. During the reciprocating swing of the first opening and closing plate, the other side of the first opening and closing plate can abut against or separate from the orifice of the flow port, and put the flow port in an open or closed state.

[0013] Furthermore, the masterbatch filling system of the masterbatch machine also includes a second opening and closing mechanism. The second opening and closing mechanism includes a second opening and closing plate and a second driving assembly. The second opening and closing plate is disposed in the storage cavity to separate the upper and lower cavities in the storage cavity. One side of the second opening and closing plate is rotatably connected to the masterbatch hopper. The second driving assembly is connected to the other side of the second opening and closing plate and is used to drive the second opening and closing plate to swing back and forth around its own rotation axis so that the other side of the second opening and closing plate abuts or separates from the masterbatch hopper. When the other side of the second opening and closing plate abuts with the masterbatch hopper, the upper and lower cavities are not connected to each other. When the other side of the second opening and closing plate separates from the masterbatch hopper, the upper and lower cavities are connected to each other.

[0014] Furthermore, the second drive assembly includes a second connecting rod and a second telescopic drive member. One end of the second connecting rod is fixedly connected to the rotation shaft of the second opening and closing plate, and the output end of the second telescopic drive member is hinged to the other end of the second connecting rod. This drives the second connecting rod to swing back and forth, so that the second opening and closing plate swings back and forth around its own rotation shaft. During the reciprocating swing of the second opening and closing plate, the other side of the second opening and closing plate can abut against or separate from the color masterbatch hopper, and keep the upper and lower cavities in the storage chamber in a connected or disconnected state.

[0015] Compared with the prior art, the beneficial effects of this utility model include: during use, the inlet is initially closed, and the masterbatch is fed into the storage chamber. By controlling the screening drive component, the screening drive component can drive the screening element to move, so that the screening element can screen the masterbatch in the storage chamber. The screened impurities fall into the impurity chamber. After the masterbatch is screened, the inlet is opened again, and the screened masterbatch enters the masterbatch chamber through the inlet. The masterbatch in the masterbatch chamber is then added to the cavity of the base via a screw conveyor. This masterbatch filling system can screen the impurities in the masterbatch and prevent the impurities from being added to the cavity of the base along with the masterbatch, thereby ensuring that the subsequent injection molding effect is not affected.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] This utility model provides a color masterbatch dispensing system for a color masterbatch machine, the structure of which is as follows: Figure 1 - Figure 4As shown, the device includes a masterbatch hopper 100 and a screening mechanism 200. The masterbatch hopper 100 has a storage chamber 110, an impurity chamber 120, and a masterbatch chamber 130. The masterbatch hopper 100 has a screening port 140 that connects the storage chamber 110 and the impurity chamber 120. The masterbatch hopper 100 also has a flow port 150 that connects the storage chamber 110 and the masterbatch chamber 130. The flow port 150 can be closed. The screening mechanism 200 includes a screening element 210 and a screening drive assembly 220. The screening element 210 is sealed at the screening port 140. The screening drive assembly 220 is connected to the screening element 210 and is used to drive the screening element 210 to screen the masterbatch in the storage chamber 110 and cause the screened impurities to fall into the impurity chamber 120.

[0019] In use, the flow port 150 is initially closed, and the masterbatch is fed into the storage chamber 110. By controlling the screening drive assembly 220, the screening component 210 can be driven to operate, allowing the screening component 210 to screen the masterbatch in the storage chamber 110. The screened impurities fall into the impurity chamber 120. After the masterbatch is screened, the flow port 150 is opened again, and the screened masterbatch enters the masterbatch chamber 130 through the flow port 150. The masterbatch in the masterbatch chamber 130 is then fed into the cavity of the base via a screw conveyor. This masterbatch feeding system can screen impurities in the masterbatch, preventing impurities from being fed into the cavity of the base along with the masterbatch, thereby ensuring that the subsequent injection molding effect is not affected.

[0020] As a preferred embodiment, please refer to Figure 2 - Figure 4 The masterbatch hopper 100 includes a masterbatch box 160 and an impurity trough 170. The impurity trough 170 is fixedly disposed within the masterbatch box 160. The space above the impurity trough 170 forms the storage cavity 110, the impurity cavity 120 is formed within the impurity trough 170, and the space below the impurity trough 170 forms the masterbatch cavity 130. The opening at the top of the impurity trough 170 forms the screening port 140. The impurity troughs 170 correspond to each other. The two long sidewalls of the container and the two corresponding inner sidewalls of the masterbatch box 160 are spaced one-to-one to form two flow ports 150. When the flow ports 150 are closed, the screening member 210 can screen the masterbatch in the storage chamber 110. After the masterbatch is screened, when the flow ports 150 are open, it can ensure that the screened masterbatch smoothly enters the masterbatch chamber 130 along the flow ports 150.

[0021] As a preferred embodiment, please refer to Figure 2 The top of the masterbatch box 160 is open to form a feeding port 161, through which masterbatch can be fed into the storage chamber 110.

[0022] As a preferred embodiment, please refer to Figure 2 The masterbatch box 160 has a slag discharge port 162 on its side wall that communicates with the impurity chamber 120. Impurities in the impurity chamber 120 can be discharged through the slag discharge port 162.

[0023] As a preferred embodiment, please refer to Figure 2 The bottom of the masterbatch box 160 is provided with a discharge port 163 that communicates with the masterbatch cavity 130. The masterbatch in the masterbatch cavity 130 can be added to the cavity of the base through the discharge port 163.

[0024] As a preferred embodiment, please refer to Figure 2 and Figure 4 The bottom surface of the impurity trough 170 is an inclined surface, and the slag discharge port 162 is located on the lower side of the bottom surface of the impurity trough 170. Impurities in the impurity trough 170 can slide down along its bottom surface to the lower side and be discharged smoothly from the slag discharge port 162. Workers do not need to reach into the interior of the impurity trough 170 to clean the impurities.

[0025] As a preferred embodiment, please refer to Figure 2 and Figure 4 The screening component 210 is a screening cylinder, which is rotatably and sealed at the screening port 140. The screening drive assembly 220 is connected to the screening cylinder and is used to drive the screening cylinder to rotate. During the rotation of the screening cylinder, the masterbatch in the storage chamber 110 can be screened, and the screened impurities fall into the impurity chamber 120. When the screening drive assembly 220 is activated, it can drive the screening cylinder to rotate. During the rotation of the screening cylinder, the masterbatch in the storage chamber 110 will be disturbed, and the impurities will pass through the screening cylinder along the screen holes on the screening cylinder and enter the impurity chamber 120, thereby realizing the screening of the masterbatch.

[0026] As a preferred embodiment, please refer to Figure 4The screening component 210 includes a main shaft 211, a frame 212, and a screen 213. The two ends of the main shaft 211 are rotatably connected to the color masterbatch hopper 100. The frame 212 is a cylindrical structure and coaxially covers the outer wall of the main shaft 211. The screen 213 is laid on the arc-shaped wall of the frame 212. The screening drive assembly 220 is connected to the main shaft 211 and is used to drive the main shaft 211 to rotate. The frame 212 supports the screen 213. The screen holes on the screen 213 allow impurities to pass through and can block the color masterbatch from passing through.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 4 The two ends of the main shaft 211 are rotatably connected to the color masterbatch box 160.

[0028] As a preferred embodiment, please refer to Figure 2 The screening drive assembly 220 includes a first rotation drive component. The output end of the first rotation drive component is detachably coaxially fixedly connected to one end of the main shaft 211. When the first rotation drive component is activated, it can drive the main shaft 211 to rotate, thereby driving the frame 212 and the screen 213 to rotate.

[0029] In a preferred embodiment, the output end of the first rotation drive can be detachably and coaxially fixedly connected to one end of the main shaft 211 via a flange or spline.

[0030] In a preferred embodiment, the first rotation drive component can be a first motor of a suitable model that is directly and detachably coaxially fixed to one end of the main shaft 211, or it can be a gear set or coupling that is indirectly and detachably coaxially fixed to one end of the main shaft 211.

[0031] As a preferred embodiment, please refer to Figure 2 The color masterbatch hopper 160 also has an installation port 164 on its side wall. The installation port 164 corresponds to the screening cylinder, and the diameter of the installation port 164 is equal to or greater than the diameter of the screening cylinder. The color masterbatch hopper 100 also includes a cover plate 180, which is detachably placed on the installation port 164 to block the installation port 164. The installation port 164 allows the screening cylinder to be disassembled and assembled through the installation port 164, making it easy to remove the screening cylinder for cleaning or replacement.

[0032] As a preferred embodiment, please refer to Figure 1 and Figure 2The masterbatch filling system of the masterbatch machine further includes a first opening and closing mechanism 300. The first opening and closing mechanism 300 includes a first opening and closing plate 310 and a first driving component 320. The first opening and closing plate 310 is disposed at the flow port 150. The first driving component 320 is connected to the first opening and closing plate 310 and is used to drive the first opening and closing plate 310 to move closer to or away from the flow port 150, and to put the flow port 150 in an open or closed state. By operating the first driving component 320, the first driving component 320 can drive the first opening and closing plate 310 to move closer to or away from the flow port 150, and to put the flow port 150 in an open or closed state. When the screening cylinder screens the masterbatch, the flow port 150 is in a closed state. When the screening cylinder finishes screening the masterbatch, the flow port 150 can be in an open state.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 3 The first opening and closing mechanism 300 includes two first opening and closing plates 310, which are inclinedly arranged at the two flow ports 150 respectively. The higher side of the first opening and closing plate 310 is close to the masterbatch box 160, and the lower side of the first opening and closing plate 310 is close to the impurity trough 170. The higher side of the first opening and closing plate 310 is rotatably connected to the masterbatch box 160. When the first opening and closing plate 310 blocks the flow port 150, the masterbatch on the first opening and closing plate 310 can slide along its inclined plate surface to the lower side, which facilitates the masterbatch to contact the surface of the filter cylinder. This facilitates the screening cylinder to screen the masterbatch on the first opening and closing plate 310, which can improve the flow rate and prevent the masterbatch from accumulating on one side of the screening cylinder.

[0034] As a preferred embodiment, please refer to Figure 2 and Figure 5One side of the first opening / closing plate 310 is rotatably connected to the color masterbatch hopper 100. The first driving assembly 320 includes a first connecting rod 321 and a first telescopic driving member 322. One end of the first connecting rod 321 is fixedly connected to the rotation axis of the first opening / closing plate 310. The output end of the first telescopic driving member 322 is hinged to the other end of the first connecting rod 321, for driving the first connecting rod 321 to reciprocate, so that the first opening / closing plate 310 reciprocates around its own rotation axis. During the reciprocating swing of the first opening / closing plate 310, the first... The other side of the opening and closing plate 310 can abut or separate from the opening of the flow port 150, and put the flow port 150 in an open or closed state. The first telescopic drive member 322 is activated, and the first telescopic drive member 322 can drive the first connecting rod 321 to swing back and forth, so that the first opening and closing plate 310 can swing back and forth around its own rotation axis. During the reciprocating swing of the first opening and closing plate 310, the other side of the first opening and closing plate 310 can abut or separate from the opening of the flow port 150, and put the flow port 150 in an open or closed state.

[0035] As a preferred embodiment, please refer to Figure 1 and Figure 2 The masterbatch filling system of the masterbatch machine further includes a second opening and closing mechanism 400. The second opening and closing mechanism 400 includes a second opening and closing plate 410 and a second driving assembly 420. The second opening and closing plate 410 is disposed in the storage cavity 110 to divide the storage cavity 110 into upper and lower cavities. One side of the second opening and closing plate 410 is rotatably connected to the masterbatch hopper 100. The second driving assembly 420 is connected to the other side of the second opening and closing plate 410 and is used to drive the second opening and closing plate 410 to reciprocate around its own rotation axis. This allows the other side of the second opening and closing plate 410 to abut or separate from the color masterbatch hopper 100. When the other side of the second opening and closing plate 410 abuts against the color masterbatch hopper 100, the upper and lower cavities are not connected to each other. When the other side of the second opening and closing plate 410 separates from the color masterbatch hopper 100, the upper and lower cavities are connected to each other. Each time, an appropriate amount of color masterbatch can be added to the lower cavity, thereby achieving batch screening of the color masterbatch in the storage cavity 110, which can improve the screening effect of the color masterbatch in the storage cavity 110.

[0036] As a preferred embodiment, please refer to Figure 2 One side of the second opening and closing plate 410 is rotatably connected to the color masterbatch box 160.

[0037] As a preferred embodiment, please refer to Figure 2 and Figure 3The second opening and closing mechanism 400 includes two second opening and closing plates 410, which are disposed opposite to each other in the storage cavity 110 to separate the upper and lower cavities within the storage cavity 110. The opposite sides of the two second opening and closing plates 410 are rotatably connected to the color masterbatch box 160. The two second driving components 420 are connected one-to-one with the opposite sides of the two second opening and closing plates 410, and are used to drive the two second opening and closing plates 410 to swing synchronously in opposite directions around their own rotation axis, so that the opposite sides of the two second opening and closing plates 410 abut or separate. When the opposite sides of the two second opening and closing plates 410 abut, the upper... The two lower cavities are not connected to each other. When the two second opening and closing plates 410 are separated on their close sides, the upper and lower cavities are connected to each other. Each time, an appropriate amount of color masterbatch can be added to the lower cavity, thereby achieving batch screening of the color masterbatch in the storage cavity 110. This can improve the screening effect of the color masterbatch in the storage cavity 110. Setting two second opening and closing mechanisms 400 can reduce the size of the storage cavity 110 in the height direction, avoiding the problem that the size of the second opening and closing plate 410 is too large and the swing radius is too large when only one second opening and closing plate 410 is set, which would cause the size of the storage cavity 110 in the height direction to be too large.

[0038] As a preferred embodiment, please refer to Figure 2 and Figure 6 The second drive assembly 420 includes a second connecting rod 421 and a second telescopic drive member 422. One end of the second connecting rod 421 is fixedly connected to the rotation axis of the second opening and closing plate 410. The output end of the second telescopic drive member 422 is hinged to the other end of the second connecting rod 421, and is used to drive the second connecting rod 421 to swing back and forth, so that the second opening and closing plate 410 swings back and forth around its own rotation axis. During the reciprocating swing of the second opening and closing plate 410, the other side of the second opening and closing plate 410 can abut or separate from the color masterbatch hopper 100, and make the upper and lower cavities in the storage chamber 110 connected or cut off. The second telescopic drive member 422 is activated. The second telescopic drive member 422 can drive the second connecting rod 421 to swing back and forth, thereby causing the second opening and closing plate 410 to swing back and forth around its own rotation axis. During the swinging process of the second opening and closing plate 410, the other side of the second opening and closing plate 410 can abut or separate from the color masterbatch hopper 100, so that the upper and lower cavities in the storage chamber 110 are in a connected or disconnected state. When the upper and lower cavities in the storage chamber 110 are in a connected state, the color masterbatch in the upper cavity falls into the lower cavity. When the upper and lower cavities in the storage chamber 110 are in a disconnected state, the color masterbatch in the upper cavity stops falling into the lower cavity.

[0039] As a preferred embodiment, please refer to Figure 1 and Figure 2 The masterbatch filling system of the masterbatch machine further includes a quantitative filling mechanism 500. The quantitative filling mechanism 500 includes an auger 510 and a quantitative filling drive assembly 520. The auger 510 is rotatably disposed in the masterbatch cavity 130. The quantitative filling drive assembly 520 is connected to one end of the auger 510 and is used to drive the auger 510 to rotate so that the auger 510 quantitatively conveys the masterbatch to the discharge port 163. By operating the quantitative filling drive assembly 520, the quantitative filling drive assembly 520 can drive the auger 510 to rotate. During the rotation of the auger 510, the masterbatch can be conveyed to the discharge port 163. Different rotation times of the auger 510 can convey different amounts of masterbatch, thereby realizing the quantitative conveying of the masterbatch.

[0040] As a preferred embodiment, please refer to Figure 2 The two ends of the auger 510 are rotatably connected to the color masterbatch box 160.

[0041] As a preferred embodiment, please refer to Figure 2 The quantitative dispensing drive assembly 520 includes a second rotation drive component. The output end of the second rotation drive component is detachably coaxially fixedly connected to one end of the auger 510. When the second rotation drive component is activated, it can drive the auger 510 to rotate, thereby realizing the quantitative delivery of the color masterbatch.

[0042] In a preferred embodiment, the output end of the second rotation drive can be detachably and coaxially fixedly connected to one end of the auger 510 via a flange or spline.

[0043] In a preferred embodiment, the second rotation drive component can be a suitable type of second motor that is directly and detachably coaxially fixedly connected to one end of the auger 510, or it can be a gear set or coupling that is indirectly and detachably coaxially fixedly connected to one end of the auger 510.

[0044] To better understand this utility model, the following is combined with... Figure 1 - Figure 6 The working principle of the technical solution of this utility model will be described in detail below: In use, the first telescopic drive 322 is activated, driving the first connecting rod 321 to reciprocate, thereby causing the first opening / closing plate 310 to reciprocate around its own rotation axis. During the reciprocating swing of the first opening / closing plate 310, the other side of the first opening / closing plate 310 can abut or separate from the opening of the flow port 150, causing the flow port 150 to be in an open or closed state. The flow port 150 is initially in a closed state, and then the two second telescopic drive 422s are activated simultaneously, driving the two second connecting rods 421 one by one to synchronously reverse direction. The two second opening and closing plates 410 reciprocate synchronously in opposite directions around their own rotation axes. During this synchronous reciprocating motion, the adjacent sides of the two second opening and closing plates 410 can abut or separate. When the adjacent sides of the two second opening and closing plates 410 abut, the upper and lower cavities are not connected. When the adjacent sides of the two second opening and closing plates 410 separate, the upper and lower cavities are connected. When the upper and lower cavities in the storage cavity 110 are connected, the masterbatch in the upper cavity falls into the lower cavity. When the upper and lower cavities of the storage chamber 110 are in a cut-off state, the masterbatch in the upper cavity stops falling into the lower cavity. The upper and lower cavities of the storage chamber 110 are first in a cut-off state, allowing the masterbatch to be fed into the upper cavity. Then, the upper and lower cavities of the storage chamber 110 are again in a cut-off state, allowing an appropriate amount of masterbatch in the upper cavity to enter the lower cavity. The first rotation drive is activated, driving the main shaft 211 to rotate, thereby rotating the screening cylinder. During the rotation of the screening cylinder, the storage chamber 110 is disturbed. Impurities in the masterbatch pass through the sieve holes on the sieve cylinder and enter the impurity chamber 120, thus achieving the screening of the masterbatch. After the masterbatch screening is completed, the flow port 150 is opened again, and the screened masterbatch enters the masterbatch chamber 130 through the flow port 150. The second rotation drive is started, which can drive the auger 510 to rotate, thereby realizing the quantitative delivery of the masterbatch. The masterbatch filling system of this masterbatch machine can screen the impurities in the masterbatch and prevent the impurities from being added into the cavity of the base along with the masterbatch, thereby ensuring that the subsequent injection molding effect is not affected.

[0045] The color masterbatch dispensing system for a color masterbatch machine provided by this utility model has the following beneficial effects: (1) The masterbatch filling system of the masterbatch machine: when the two second opening and closing plates 410 are close to each other, the upper and lower cavities are not connected to each other. When the two second opening and closing plates 410 are separated, the upper and lower cavities are connected to each other. Each time, an appropriate amount of masterbatch can be added to the lower cavity, so as to achieve batch screening of the masterbatch in the storage cavity 110. This can improve the screening effect of the masterbatch in the storage cavity 110. Setting two second opening and closing mechanisms 400 can reduce the size of the storage cavity 110 in the height direction, and avoid the problem that the size of the second opening and closing plate 410 is too large and the swing radius is too large when only one second opening and closing plate 410 is set, which causes the size of the storage cavity 110 in the height direction to be too large. (2) The masterbatch filling system of the masterbatch machine, the output end of the first rotating drive can be detachably coaxially fixedly connected to one end of the main shaft 211 via a flange or spline, and the mounting port 164 is provided so that the screening cylinder can be disassembled and assembled via the mounting port 164, making it easy to take out the screening cylinder for cleaning or replacement. (3) The masterbatch filling system of the masterbatch machine can screen the impurities in the masterbatch and prevent the impurities from being added into the cavity of the base along with the masterbatch, so as to ensure that the subsequent injection molding effect is not affected.
