[0032] Reference below Figures 1 to 7 A masterbatch machine according to an embodiment of the present invention will be described.

[0033] like Figure 1 and Figure 2 As shown, the masterbatch machine according to the embodiment of the present invention includes a main body 100 , a feeding sleeve 200 and a motor 300 .

[0034] A material storage chamber 110 is provided in the main body 100; a material inlet 211 is provided at one end of the feeding sleeve 200, and a material outlet 212 is provided at the other end, and the material inlet 211 is connected to the material storage chamber 110; a threaded groove 213 is provided on the inner wall of the feeding sleeve 200; and a motor 300 is connected to the feeding sleeve 200 for driving the feeding sleeve 200 to rotate.

[0035] For example Figure 2 and Figure 3 As shown, a storage chamber 110 is provided in the main body 100 of the masterbatch machine. The storage chamber 110 is used to place masterbatch. The feeding sleeve 200 is connected to the storage chamber 110 through the feeding port 211. The masterbatch first enters the storage chamber 110, and then enters the inner space of the feeding sleeve 200 through the feeding port 211 connected to the storage chamber 110. The motor 300 is connected to the feeding sleeve 200 and is used to drive the feeding sleeve 200 to rotate. When the masterbatch enters the inner space of the feeding sleeve 200 from the storage chamber 110 through the feeding port 211 of the feeding sleeve 200, the feeding sleeve 200 starts to rotate under the driving action of the motor 300, and the masterbatch starts to roll forward in the feeding sleeve 200. Due to the effect of the thread groove 213 , the masterbatch will be evenly arranged in the process of rolling forward, and by controlling the pitch of the thread groove 213 , only a small amount of masterbatch exists in the thread groove 213 between adjacent teeth of the thread groove 213 .

[0036] It should be understood that the thread groove 213 plays a role in fixing the position of the masterbatch, because the rotation of the feeding sleeve 200 drives the masterbatch to roll forward in the thread groove 213. It is easy to understand that a large number of masterbatch may enter the feed port 211 at the same time, because the rotation of the feeding sleeve 200 allows the masterbatch close to the thread groove 213 of the feeding sleeve 200 to roll forward, while the masterbatch not close to the thread groove 213 moves at a slower speed. The masterbatch close to the thread groove 213 rolls forward quickly, while the masterbatch not close to the thread groove 213 is located at the rear and has a slower speed, which is separated from the masterbatch located in the front, and only the masterbatch close to the thread groove 213 moves forward quickly.

[0037] It should be understood that multiple masterbatches in the thread groove 213 at the same horizontal position will collide in the thread groove 213 due to rolling forward, and the mutual collision causes the masterbatches located at a relatively high position in the thread groove 213 at the same horizontal position to be collided into the thread groove 213 relatively forward or backward, until only a small amount of masterbatches remain in the thread groove 213 at the same horizontal position and cannot collide, for example, only one or two masterbatches remain. The appropriate length of the feeding sleeve 200 can ensure that there are only a small amount of masterbatches in the thread groove 213 near the discharge port 212 of the feeding sleeve 200, thereby achieving micro-discharging, so that the produced products have no color difference and are of high quality.

[0038] In some specific embodiments of the present invention, the groove width of the thread groove 213 is in the range of 4 to 6 mm.

[0039] It is easy to understand that the general diameter of the masterbatch machine is 2-3 mm, so setting the groove width range of the thread groove 213 to 4-6 mm can ensure that only 1-2 masterbatches are stored in the thread groove 213, thereby ensuring accurate material feeding.

[0040] In some specific embodiments of the present invention, a spirally arranged feeding tube 214 is disposed in the feeding sleeve 200 , and the grooves between two adjacent circles of the feeding tube 214 form a thread groove 213 ; one end of the feeding tube 214 protrudes from the discharge port.

[0041] The thread groove 213 in the feeding sleeve 200 can be directly provided on the feeding sleeve 200, or a feeding tube 214 can be provided in the feeding sleeve 200, and the thread groove 213 on the feeding tube 214 is used to transmit the masterbatch. Figure 6 As shown, a spirally arranged feeding tube 214 is disposed in the feeding sleeve 200 , and the grooves between two adjacent circles of the feeding tube 214 form a thread groove 213 .

[0042] When the thread groove 213 is disposed on the feed tube 214 , one end of the feed tube 214 may protrude from one end of the discharge port 212 of the feed sleeve 200 , so that the masterbatch is in the thread groove 213 of the feed tube 214 during the transportation stage in the feed sleeve 200 .

[0043] In some specific embodiments of the present invention, the feeding sleeve 200 includes a feeding portion 210 and a connecting portion 220. The feeding portion 210 is barrel-shaped, with a threaded groove 213 provided on the inner wall, an outlet 212 provided at one end, and the other end is connected to the connecting portion 220 and provided with a plurality of inlets 211; the feeding portion 210 is connected to the motor 300 through the connecting portion 220.

[0044] For example Figure 4 and Figure 5The feeding sleeve 200 shown includes a feeding part 210 and a connecting part 220. The feeding part 210 is similar in shape to a barrel, with one end opening as a discharge port 212, and the other end opening a plurality of feed ports 211 connected to the connecting part 220. By making the feeding part 210 into a barrel shape instead of a tube shape, the feed port 211 of the feeding part 210 has a bottom wall, and the feed port 211 is opened on the bottom wall so that the diameter of the feed port 211 can be controlled, and the diameter of the feed port 211 is smaller than the diameter of the discharge port 212 of the feeding part 210, so that the amount of masterbatch entering the feeding sleeve 200 from the feed port 211 can be controlled, and will not be too much to affect the rolling of the masterbatch in the feeding sleeve 200. The inner wall of the feeding sleeve 200 is fixedly provided with a thread groove 213 for driving the masterbatch to roll forward.

[0045] The connecting portion 220 is in the shape of a rod, one end of which is connected to the bottom wall of the feeding portion 210, and the other end is connected to the motor 300, so that the motor 300 can drive the feeding portion 210 to rotate through the connecting portion 220. Furthermore, the connecting portion 220 is connected to the center of the bottom wall of the feeding portion 210, thereby ensuring that the feeding portion 210 does not rotate eccentrically, and the feeding ports 211 are evenly distributed on the bottom wall of the feeding portion 210 around the connecting portion 220.

[0046] Furthermore, the connecting portion 220 is connected to the motor 300 via a coupling 221 .

[0047] For example Figure 3 and Figure 4 As shown, one end of the connecting portion 220 is fixedly connected to the feeding portion 210, and the other end is connected to the motor 300 through a coupling 221. Furthermore, the connecting portion 220 and the feeding portion 210 are integrally formed to increase structural stability and firmness.

[0048] In some specific embodiments of the present invention, the main body 100 is further provided with a conveying pipe 120 , and the feeding portion 210 is rotatably disposed in the conveying pipe 120 .

[0049] For example Figure 2 and Figure 3 As shown, the main body 100 is also provided with a conveying pipe 120, which is hollow inside and the feeding part 210 is sleeved inside, so that the conveying pipe 120 plays a role of rotation support for the feeding part 210, so that the rotation of the feeding part 210 is more stable, and the conveying pipe 120 is located outside the feeding part 210, which can help the feeding part 210 resist external force impact, so that the feeding part 210 will not be displaced by external force, thereby ensuring the feeding accuracy.

[0050] In some specific embodiments of the present invention, a storage hopper 410, a support frame 430 and a weighing sensor 420 are also included. The storage hopper 410 is located at the top of the storage chamber 110 and is used to transport materials to the storage chamber 110; the storage hopper 410 is connected to the support frame 430 through the weighing sensor 420, and the weighing sensor 420 is connected to the storage hopper 410 for detecting weight changes in the storage hopper 410.

[0051] For example Figure 2 As shown, the masterbatch machine also includes a storage hopper 410 and a weighing sensor 420. The storage hopper 410 is located at the top of the storage cavity 110 and is used to transport materials to the storage cavity 110. The storage hopper 410 is not in direct contact with the storage cavity 110 but is only connected to the weighing sensor 420. The connection with the weighing sensor 420 is a soft connection with a floating characteristic, so that the storage hopper 410 is suspended and fixed above the storage cavity 110. By using the principle of weightlessness, the weighing sensor 420 can accurately monitor the masterbatch in the storage hopper 410.

[0052] The masterbatch discharged is monitored by weighing and weight loss principle, and the weight detection is realized when the storage hopper 410 discharges the material, so as to achieve the purpose of accurately measuring the weight of the masterbatch discharged by the storage hopper 410.

[0053] For example Figure 1 and Figure 2 As shown, the support frame 430 is fixedly connected to the main body 100, and the storage hopper 410 is fixedly connected to the support frame 430 through the weighing sensor 420. The support frame 430 can be in other shapes such as funnel, plate or rod, and plays a supporting role, supporting the weighing sensor 420 and the storage hopper 410, so that the storage hopper 410 can be suspended above the storage cavity 110 to transport the masterbatch to the storage cavity 110. The storage hopper 410 is connected to the weighing sensor 420 in a floating manner, so that the weighing sensor 420 can accurately measure the weight of the masterbatch falling from the storage hopper 410.

[0054] Furthermore, the support frame 430 is configured to be funnel-shaped, fixedly connected to the main body 100 of the masterbatch machine at the bottom, and encloses the upper feed port of the storage chamber 110 and the storage hopper 410 therein, which not only supports the storage hopper 410, but also wraps it more tightly, preventing other contaminants from entering the storage chamber 110 through the upper feed port of the storage chamber 110 and affecting the feeding accuracy.

[0055] In some specific embodiments of the present invention, a controller is further included, and the controller is electrically connected to the weighing sensor 420 and the motor 300 .

[0056] The controller is electrically connected to the weighing sensor 420 and the motor 300, and the weighing sensor 420 is used to sample and transmit the material discharging data in real time. The controller processes the data and controls the rotation speed of the motor 300 to achieve the purpose of accurate material discharging. The production data is also generated into a chart for easy viewing and calling at any time.

[0057] Furthermore, the controller can convert data into a curve chart for display in real time through real-time data collection and material consumption management control software, so that the staff can clearly know the consumption of the machine and make production adjustments. In addition, through the wireless Bluetooth transmission mode, the machine operation status can be checked at any time using a mobile phone, and users can receive equipment operation status and emergency alarm information in the form of text messages.

[0058] During the unloading process of the masterbatch machine, the masterbatch in the storage hopper 410 gradually decreases. When the weighing sensor 420 detects that the weight of the masterbatch in the storage hopper 410 is lower than the minimum weight set by the controller, the staff can be reminded to add material or a collecting box can be set at the feed port of the storage hopper 410 for automatic addition controlled by the controller.

[0059] In some specific embodiments of the present invention, a suction pipe 500 is further included. The suction pipe 500 is located at the bottom of the material storage chamber 110 and is communicated with the material storage chamber 110 .

[0060] For example Figure 2 and Figure 3 As shown, the suction pipe 500 is located at the bottom of the material storage chamber 110 and is connected to the material storage chamber 110 .

[0061] When the masterbatch machine has reached the appropriate amount of material for a certain masterbatch, the masterbatch machine stops feeding, and some masterbatch is still inside the feeding sleeve 200 and the storage chamber 110. This part of the masterbatch cannot fall directly from the discharge port 212, otherwise it will affect the masterbatch composition ratio and produce color difference. At the same time, it is very difficult to discharge it from the entrance of the storage chamber 110, and it cannot be discharged completely. There are still some masterbatch remaining in the storage chamber 110 or the feeding sleeve 200, which will still affect the composition ratio of the masterbatch when the next batch of masterbatch comes in. Therefore, a suction pipe 500 is set at the bottom of the storage chamber 110, which is used to discharge and collect the masterbatch in the feeding sleeve 200 and the storage chamber 110 after the masterbatch needs to be changed or the feeding is stopped.

[0062] When the masterbatch machine needs to change materials or stops feeding, the suction pipe 500 is opened and the motor 300 is reversed to send the masterbatch in the feeding sleeve 200 back to the storage chamber 110. The suction pipe 500 sucks the masterbatch in the storage chamber 110 to discharge the masterbatch in the feeding sleeve 200 and the storage chamber 110 without affecting the purity of the next masterbatch. The suction pipe 500 discharges the masterbatch completely by the weight of the masterbatch itself and the suction force of the suction pipe 500 on the masterbatch.

[0063] In some specific embodiments of the present invention, a material baffle plate 600 is further included. The material baffle plate 600 is located at the bottom of the material storage chamber 110 . The material baffle plate 600 is used to open or close the passage between the suction pipe 500 and the material storage chamber 110 .

[0064] For example Figure 3 and Figure 7 As shown, the baffle plate 600 is plate-shaped and located at the bottom of the material storage chamber 110 , and is provided with a material drop hole 610 . The baffle plate 600 is used to open or close the passage between the suction pipe 500 and the material storage chamber 110 .

[0065] For example Figure 7 As shown, the baffle plate 600 is in the shape of a plate, with a drop hole 610 corresponding to the diameter of the tube mouth of the suction tube 500 in the middle. When the suction tube 500 does not need to work, the plate surface of the baffle plate 600 blocks the passage between the suction tube 500 and the storage chamber 110. When the suction tube 500 needs to work, the baffle plate 600 can be moved to align the drop hole 610 on the baffle plate 600 with the passage between the suction tube 500 and the storage chamber 110, so that the passage between the suction tube 500 and the storage chamber 110 is opened, so that the masterbatch can be discharged from the masterbatch machine through the suction tube 500.

[0066] The baffle is located in the passage between the suction pipe 500 and the material storage chamber 110 , and can be moved by a pneumatic device so that the drop hole 610 located thereon is aligned with the suction pipe 500 , thereby opening the passage between the suction pipe 500 and the material storage chamber 110 .

[0067] In some specific embodiments of the present invention, an air blowing device 700 is further included. The air blowing device 700 is disposed at the material outlet 212 for blowing back the material.

[0068] For example Figure 1 and Figure 2 As shown, the air blowing device 700 is arranged at the discharge port 212 for blowing back the material. When the masterbatch machine needs to change the material, the material in the feeding sleeve 200 can be reversed by the motor 300 to transport the masterbatch back to the storage chamber 110. At the same time, the air blowing device 700 blows air back, so that the masterbatch can return to the storage chamber 110 faster and the recovery of the masterbatch can be more thorough.

[0069] The following refers to Figures 1 to 7 A color masterbatch machine according to an embodiment of the present invention will be described in detail with a specific embodiment. It should be understood that the following description is only an exemplary illustration and not a specific limitation of the present invention.

[0070] As Figure 1 and Figure 2 As shown, the color masterbatch machine includes a main body part 100, a feeding sleeve 200, and a motor 300. A storage cavity 110 is formed in the main body part 100 of the color masterbatch machine, and the storage cavity 110 is used to place color masterbatch. The feeding sleeve 200 is communicated with the storage cavity 110 through a feeding port 211. The color masterbatch particles first enter the storage cavity 110, and then enter the internal space of the feeding sleeve 200 through the feeding port 211 communicated with the storage cavity 110. The motor 300 is connected to the feeding sleeve 200 and is used to drive the feeding sleeve 200 to rotate. When the color masterbatch particles enter the internal space of the feeding sleeve 200 from the storage cavity 110 through the feeding port 211 of the feeding sleeve 200, the feeding sleeve 200 starts to rotate under the driving action of the motor 300, and the color masterbatch particles start to roll forward in the feeding sleeve 200 accordingly.

[0071] The feeding sleeve 200 includes a feeding part 210 and a connecting part 220. The shape of the feeding part 210 is similar to that of a barrel, the top opening thereof is a discharging port 212, and a plurality of feeding ports 211 are formed in the bottom wall. The shape of the feeding part 210 is made into a barrel shape instead of a tubular shape, so that the feeding part 210 has a bottom wall at the feeding port 211, and the feeding port 211 can be formed on the bottom wall, and the diameter of the feeding port 211 is controllable, so that the diameter of the feeding port 211 is smaller than the diameter of the discharging port 212 of the feeding part 210. Therefore, the number of color masterbatch particles entering the internal space of the feeding sleeve 200 from the feeding port 211 is controllable and will not be too much to affect the rolling of the color masterbatch particles in the feeding sleeve 200. A thread groove 213 is fixedly arranged on the inner wall of the feeding sleeve 200 for driving the color masterbatch particles to roll forward. The feeding sleeve 200 is located in the conveying pipe 120 of the color masterbatch machine, and the conveying pipe 120 plays a role of rotational support for the feeding part 210.

[0072] The connecting part 220 is rod-shaped, one end of which is connected to the bottom wall of the feeding part 210, and the other end is connected to the motor 300 through a coupling 221, so that the motor 300 can drive the feeding part 210 to rotate through the connecting part 220.

[0073] A spiral arrangement of feeding pipes 214 is provided in the feeding sleeve 200, and the grooves between two adjacent turns of the feeding pipes 214 form the thread groove 213.

[0074] When the thread groove 213 is disposed on the feed tube 214 , one end of the feed tube 214 may protrude from one end of the discharge port 212 of the feed sleeve 200 , so that the masterbatch is in the thread groove 213 of the feed tube 214 during the transportation stage in the feed sleeve 200 .

[0075] For example Figure 2 As shown, the masterbatch machine further includes a storage hopper 410, a support frame 430 and a weighing sensor 420. The support frame 430 is fixedly connected to the main body 100. The storage hopper 410 is fixedly connected to the support frame 430 through the weighing sensor 420, so that it is suspended above the storage cavity 110 and can transport the masterbatch to the storage cavity 110. The storage hopper 410 is connected to the weighing sensor 420 in a floating manner, so that the weighing sensor 420 can accurately measure the weight of the masterbatch falling from the storage hopper 410.

[0076] The masterbatch machine is also provided with a controller, which is electrically connected to the weighing sensor 420 and the motor 300. The weighing sensor 420 is used to sample and transmit the material feeding amount data in real time. The controller processes the data and controls the rotation speed of the motor 300 to achieve the purpose of accurate material feeding. In addition, the production data can be generated into a chart for easy viewing and calling at any time.

[0077] For example Figure 2 and Figure 3 As shown, the masterbatch machine is also provided with a material suction pipe 500 , a material baffle plate 600 and an air blowing device 700 .

[0078] The suction pipe 500 is located at the bottom of the storage chamber 110 and is connected to the storage chamber 110. The baffle plate 600 is in the shape of a plate, and a drop hole 610 corresponding to the diameter of the pipe opening of the suction pipe 500 is opened in the middle. When the suction pipe 500 does not need to work, the plate surface of the baffle plate 600 blocks the passage between the suction pipe 500 and the storage chamber 110. When the suction pipe 500 needs to work, the baffle plate 600 can be moved to align the drop hole 610 on the baffle plate 600 with the passage between the suction pipe 500 and the storage chamber 110, so that the passage between the suction pipe 500 and the storage chamber 110 is opened and the masterbatch can be discharged through the suction pipe 500. The baffle plate is located in the passage between the suction pipe 500 and the storage chamber 110, and is translated by a pneumatic device so that the drop hole 610 located thereon is aligned with the suction pipe 500, thereby opening the passage between the suction pipe 500 and the storage chamber 110.

[0079] The air blowing device 700 is arranged at the discharge port 212 and is used to blow back the material. When the masterbatch machine needs to change materials, the material in the feeding sleeve 200 can be reversed by the motor 300 so that the masterbatch is transported back to the storage chamber 110. At the same time, the air blowing device 700 blows air back so that the masterbatch can return to the storage chamber 110 faster and the recovery of the masterbatch can be more thorough.

[0080] According to the masterbatch machine of the embodiment of the present invention, by such a configuration, at least the following effects can be achieved: the masterbatch enters the storage chamber 110 from the storage hopper 410, and then enters the inside of the feeding sleeve 200 from the feeding port 211, and the feeding sleeve 200 is precisely rotated by controlling the speed of the motor 300. The feeding sleeve 200 is driven by the motor 300 to rotate, so that the masterbatch rolls forward in the feeding sleeve 200. Due to the effect of the thread groove 213, the masterbatch will be evenly arranged in the process of rolling forward. By controlling the pitch of the thread groove 213, only a small amount of masterbatch exists between the thread grooves 213 between the adjacent teeth of the thread groove 213, thereby ensuring that a small amount of material can be fed, so that the products produced have no color difference and are of high quality.

[0081] At the same time, a suction pipe 500 is arranged at the bottom of the storage chamber 110, and the suction pipe 500 is connected with the storage chamber 110, and a baffle plate 600 is arranged in the channel. When the masterbatch machine needs to change materials, the baffle plate 600 opens the channel between the suction pipe 500 and the storage chamber 110, so that the masterbatch can be discharged from the masterbatch machine through the suction pipe 500, and an air blowing device 700 is arranged at the outlet 212 of the feeding sleeve 200 for blowing back the material. When the masterbatch machine needs to change materials, the material in the feeding sleeve 200 can be reversed by the motor 300 to transport the masterbatch back to the storage chamber 110, and the air blowing device 700 blows air back, so that the masterbatch can return to the storage chamber 110 faster, and the recovery of the masterbatch is more thorough.
