Description

Technical Field

[0001] This utility model relates to the field of extruders, and in particular to a plastic masterbatch blending extruder. Background Technology

[0002] As a common extrusion molding machine, the extruder's production process involves using the rotation of a screw to extrude heated and molten thermoplastic raw materials from a die head with the desired cross-sectional shape. The materials are then shaped by a sizing device and hardened by a cooler.

[0003] To meet the market's demand for diversified products, color masterbatches are usually mixed with other raw materials to change color or properties. For mixtures in the proportioning and debugging stage, before each proportioning, an appropriate amount of raw materials need to be mixed in a mixer in proportion, and then put into the feed hopper of the extruder. The whole process requires constant back-and-forth operation between the mixer and the extruder, which is time-consuming and labor-intensive. Utility Model Content

[0004] To facilitate the direct mixing and proportioning of color masterbatch and other raw materials within the extruder feed hopper, and to reduce the cumbersome process of repeated operations between the mixer and the extruder, this application provides a plastic color masterbatch blending extruder.

[0005] The plastic masterbatch blending extruder provided in this application adopts the following technical solution:

[0006] A plastic masterbatch blending extruder includes a frame, a barrel, a screw rotatably disposed within the barrel, and a first motor driving the screw to rotate. The barrel has a feed hopper at its inlet end and an extrusion die at its outlet end. The feed hopper contains a stirring assembly and a partition assembly. The partition assembly includes a partition plate and a driving component. A through groove is formed on one side of the feed hopper. The partition plate slides horizontally on the through groove, with its two ends located on the inner and outer sides of the feed hopper, respectively. The driving component is disposed on the feed hopper to drive the partition plate to move. The partition plate divides the feed hopper into an upper stirring zone and a lower mixing zone. The stirring assembly is used to mix the raw materials within the stirring zone.

[0007] By adopting the above technical solution, when mixing color masterbatch with other raw materials, the raw materials can be first placed into the mixing zone of the feed hopper. The drive unit controls the partition to close the mixing zone below the feed hopper, preventing unevenly mixed raw materials from entering the extruder barrel prematurely. After the mixing assembly fully mixes the raw materials in the mixing zone, the drive unit drives the partition to move, opening the channel so that the evenly mixed mixture falls into the mixing zone below and then enters the extruder barrel. This achieves direct mixing of the color masterbatch mixture in the feed hopper, eliminating the need to operate back and forth between the mixer and the extruder, improving work efficiency and simplifying the operation process. At the same time, while the color masterbatch mixture in the mixing zone is being extruded, the mixing zone can mix the raw materials for the next ratio.

[0008] Preferably, the stirring assembly includes a second motor, a stirring shaft, and stirring blades. The second motor is fixedly mounted on the feed hopper, and the output shaft of the second motor is coaxially fixedly mounted on the stirring shaft. The stirring shaft is rotatably connected to the feed hopper, and the stirring blades are located in the stirring zone and mounted on the stirring shaft.

[0009] By adopting the above technical solution, after the second motor starts, it drives the stirring shaft to rotate, and the stirring blades on the stirring shaft rotate accordingly, so as to fully stir and mix the color masterbatch and other raw materials in the stirring zone.

[0010] Preferably, the feed hopper is equipped with a clearing component, which is located in the mixing zone and is used to clear the discharge port of the mixing zone.

[0011] Preferably, the unblocking component includes a second driving component, a fixed frame, a rotating shaft, and an unblocking block. The fixed frame is fixedly installed on the inner wall of the feed hopper, the rotating shaft is rotatably connected to the fixed frame around the vertical axis, and the unblocking block is fixedly installed at the bottom end of the rotating shaft and located at the discharge port of the mixing zone.

[0012] By adopting the above technical solution, the partition opens, and the mixed raw materials in the mixing zone enter the mixing zone below. Then the partition closes, and the drive component two drives the rotating shaft and the unblocking block to rotate. The unblocking block agitates the raw materials at the discharge port to prevent the raw materials from clumping and blocking, so that the raw materials can smoothly enter the extruder barrel from the mixing zone. This makes the extruder's operation smoother, avoids downtime and cleaning caused by blockage, and improves production efficiency and equipment stability.

[0013] Preferably, the second driving component includes a gear and a tooth surface. The gear is coaxially fixedly mounted on the top of the rotating shaft. A horizontal groove is formed on the bottom surface of the partition plate. The gear moves within the horizontal groove. The tooth surface is formed on one side wall of the horizontal groove. The gear meshes with the tooth surface.

[0014] By adopting the above technical solution, when the partition moves under the action of the first driving component, the gear rolls along the tooth surface in the transverse groove, thereby driving the rotating shaft and the unblocking block to rotate, converting the horizontal movement of the partition into the rotation of the unblocking block. There is no need to set up an additional power source to drive the unblocking component. The structure is compact, reducing equipment cost and energy consumption. At the same time, it realizes the linkage between the partition component and the unblocking component, improving the automation level and work coordination of the equipment.

[0015] Preferably, the top surface of the partition plate has a downward inclined surface at one end of the stirring zone.

[0016] By adopting the above technical solution, the inclined surface of the top of the partition allows the mixed raw materials in the mixing zone to slide more smoothly into the mixing zone under the action of gravity after the partition is opened, avoiding the accumulation and residue of raw materials at the junction of the mixing zone and the mixing zone, and ensuring the thoroughness of raw material transfer.

[0017] Preferably, the driving component includes an electric cylinder and a connecting block. The electric cylinder is fixedly mounted on the feed hopper, and the output shaft of the electric cylinder extends outward toward the side away from the feed hopper along a moving direction parallel to the partition. The two ends of the connecting block are respectively fixed to the output shaft of the electric cylinder and the partition.

[0018] By adopting the above technical solution, the opening and closing of the baffle can be flexibly controlled according to actual production needs, so as to achieve precise operation of the separation and connection of the stirring zone and the mixing zone, thereby better coordinating with the working rhythm of the stirring components and the extruder, and ensuring that the entire extrusion process is carried out efficiently and orderly.

[0019] The main technical effects of this utility model are reflected in the following aspects:

[0020] 1. When mixing color masterbatch with other raw materials, the raw materials can be placed into the mixing zone of the feed hopper first. The drive unit controls the partition to close the mixing zone below the feed hopper, preventing unevenly mixed raw materials from entering the extruder barrel in advance. After the mixing assembly fully mixes the raw materials in the mixing zone, the drive unit drives the partition to move and open the channel, allowing the evenly mixed mixture to fall into the mixing zone below and then enter the extruder barrel. This realizes the direct mixing of color masterbatch mixture in the feed hopper, eliminating the need to operate back and forth between the mixer and the extruder, improving work efficiency and simplifying the operation process.

[0021] 2. When the partition of this utility model is opened, the raw materials mixed in the mixing zone enter the mixing zone below. Then the partition is closed, and the rotating shaft and the unblocking block are driven by the second drive component to rotate. The unblocking block is used to stir the raw materials at the discharge port to prevent the raw materials from clumping and blocking. This allows the raw materials to smoothly enter the extruder barrel from the mixing zone, making the extruder operation process smoother, avoiding downtime and cleaning caused by blockage, and improving production efficiency and equipment stability.

[0027] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0028] This application discloses a plastic masterbatch blending extruder.

[0029] Reference Figures 1-3 This embodiment of a plastic masterbatch blending extruder includes a frame 1, a barrel 21, a screw 22 rotatably disposed within the barrel 21, and a first motor 23 for driving the screw 22 to rotate. The feed end of the barrel 21 is provided with a feed hopper 3, and the discharge end of the barrel 21 is provided with an extrusion die 24. The feed hopper 3 is provided with a stirring assembly 4 and a partition assembly 5. The partition assembly 5 includes a partition plate 51 and a driving component. A through groove 54 is opened on one side of the feed hopper 3. The partition plate 51 slides horizontally on the through groove 54. The two ends of the partition plate 51 are respectively located on the inner and outer sides of the feed hopper 3. The driving component is disposed on the feed hopper 3 for driving the partition plate 51 to move. The partition plate 51 divides the feed hopper 3 into an upper stirring zone 55 and a lower mixing zone 56. The stirring assembly 4 is used to mix the raw materials in the stirring zone 55.

[0030] Reference Figures 1-3When mixing masterbatch with other raw materials, the raw materials can be first placed into the mixing zone 55 of the feed hopper 3. The drive unit controls the partition 51 to close the mixing zone 56 below the feed hopper 3, preventing unevenly mixed raw materials from entering the extruder barrel 21 in advance. After the mixing assembly 4 fully mixes the raw materials in the mixing zone 55, the drive unit drives the partition 51 to move and open the channel, allowing the evenly mixed mixture to fall into the mixing zone 56 below and then into the extruder barrel 21. This achieves direct mixing of the masterbatch mixture in the feed hopper 3, eliminating the need to operate back and forth between the mixer and the extruder, improving work efficiency and simplifying the operation process. At the same time, while the masterbatch mixture in the mixing zone 56 is being extruded, the mixing zone 55 can be used to mix the raw materials for the next ratio.

[0031] Reference Figure 2 and Figure 3 The stirring assembly 4 includes a second motor 41, a stirring shaft 42, and stirring blades 43. The second motor 41 is fixedly mounted on the feed hopper 3, and the output shaft of the second motor 41 is coaxially fixedly mounted on the stirring shaft 42. The stirring shaft 42 is rotatably connected to the feed hopper 3, and the stirring blades 43 are located in the stirring zone 55 and mounted on the stirring shaft 42.

[0032] Reference Figure 2 and Figure 3 After the second motor 41 starts, it drives the stirring shaft 42 to rotate, and the stirring blades 43 on the stirring shaft 42 rotate accordingly, so as to fully stir and mix the color masterbatch and other raw materials in the stirring zone 55.

[0033] Reference Figures 2-4 The feed hopper 3 is equipped with a dredging component 6, which is located in the mixing zone 56 and is used to dredge the discharge port of the mixing zone 56.

[0034] Reference Figures 2-4 The unblocking component 6 includes a driving component 2, a fixed frame 63, a rotating shaft 64, and an unblocking block 65. The fixed frame 63 is fixedly installed on the inner wall of the feed hopper 3. The rotating shaft 64 is rotatably connected to the fixed frame 63 around the vertical axis. The unblocking block 65 is fixedly installed at the bottom of the rotating shaft 64 and located at the discharge port of the mixing zone 56.

[0035] Reference Figures 1-4 When the partition 51 is opened, the raw material mixed in the mixing zone 55 enters the mixing zone 56 below. Then the partition 51 is closed, and the rotating shaft 64 and the unblocking block 65 are rotated by the second drive component. The unblocking block 65 is used to stir the raw material at the discharge port to prevent the raw material from clumping and blocking, so that the raw material can smoothly enter the extruder barrel 21 from the mixing zone 56. This makes the working process of the extruder smoother, avoids downtime and cleaning caused by blockage, and improves production efficiency and equipment stability.

[0036] Reference Figures 2-4The second driving component includes a gear 61 and a tooth surface 62. The gear 61 is coaxially fixed at the top of the rotating shaft 64. A horizontal groove 511 is provided on the bottom surface of the partition 51 along the horizontal direction. The gear 61 moves in the horizontal groove 511. The tooth surface 62 is opened on one side wall of the horizontal groove 511. The gear 61 meshes with the tooth surface 62.

[0037] Reference Figures 2-4 When the partition 51 moves under the action of the driving component, the gear 61 rolls along the tooth surface 62 in the transverse groove 511, thereby driving the rotating shaft 64 and the unblocking block 65 to rotate. This converts the horizontal movement of the partition 51 into the rotation of the unblocking block 65. There is no need to set up an additional power source to drive the unblocking component 6. The structure is compact, which reduces equipment cost and energy consumption. At the same time, it realizes the linkage between the partition component 5 and the unblocking component 6, which improves the automation level and work coordination of the equipment.

[0038] Reference Figures 2-4 The top surface of the partition 51 is provided with a downward inclined surface 512 at one end of the mixing zone 55.

[0039] Reference Figures 2-4 The inclined surface 512 on the top surface of the partition 51 allows the mixed raw materials in the mixing zone 55 to slide more smoothly into the mixing zone 56 under the action of gravity after the partition 51 is opened, avoiding the accumulation and residue of raw materials at the junction of the mixing zone 55 and the mixing zone 56, and ensuring the thoroughness of raw material transfer.

[0040] Reference Figure 2 and Figure 3 The driving component includes an electric cylinder 52 and a connecting block 53. The electric cylinder 52 is fixedly mounted on the feed hopper 3. The electric cylinder 52 and the second motor 41 are respectively located on both sides of the feed hopper 3. The output shaft of the electric cylinder 52 extends outward from the feed hopper 3 along a direction parallel to the movement of the partition 51. The two ends of the connecting block 53 are detachably fixed to the output shaft of the electric cylinder 52 and the partition 51, respectively. The fixing method can be any method that allows for disassembly and assembly, such as screws.

[0041] Reference Figure 2 and Figure 3 The opening and closing of the partition 51 can be flexibly controlled according to actual production needs, so as to achieve precise operation of the separation and connection of the stirring zone 55 and the mixing zone 56, thereby better coordinating with the working rhythm of the stirring component 4 and the extruder, and ensuring that the entire extrusion process is carried out efficiently and orderly.

[0042] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
