Description
Technical Field
[0001] This utility model relates to the field of plastic woven bag production technology, specifically a multi-directional mixer for raw materials used in woven bag production. Background Technology
[0002] Woven bag production is a process of transforming raw materials into finished woven bags through a series of processing steps. The main raw material for producing woven bags is polypropylene, and high-density polyethylene, linear low-density polyethylene, etc. are also used. When producing woven bags, these raw materials need to be mixed evenly, so a mixer is used to mix the raw materials.
[0003] For example, patent CN222360454U discloses a raw material mixing device for the production of plastic woven bags, including a mixer. By setting up a mixer and a stirring mechanism, the mixer and stirring mechanism work together. When mixing the raw materials, the raw materials are first added into the mixer, and then a servo motor is activated. The servo motor drives an output rod to rotate, which in turn drives an output wheel to rotate. The rotation of the output wheel simultaneously drives a first bevel gear and a second bevel gear, which are meshed together, to rotate clockwise and counterclockwise, respectively. When the first bevel gear rotates clockwise, it can... The stirring shaft rotates clockwise, which drives the blades to rotate clockwise. When the second bevel gear rotates counterclockwise, it drives the stirring rod to rotate counterclockwise. The counterclockwise rotation of the stirring rod also drives the stirring blades to rotate counterclockwise. Thus, the stirring blades and stirring blades can simultaneously stir and mix in opposite directions, improving the stirring efficiency and enhancing the mixing effect on the raw materials. In the above case, reverse stirring is achieved through multiple gear drives. Relying on only two stirring components rotating in opposite directions, the stirring method is relatively simple, and the disturbance and mixing path of the materials are limited, making it difficult to handle materials with complex characteristics or high viscosity.
[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing multi-directional mixing machine for raw materials used in woven bag production. Utility Model Content
[0005] The purpose of this invention is to provide a multi-directional mixer for raw materials used in woven bag production, in order to solve the problems mentioned in the background art, which rely on multiple gear drives to achieve reverse mixing, and only two opposing rotating mixing components. The mixing method is relatively simple, the disturbance and mixing path of the material are limited, and it is difficult to handle raw materials with complex characteristics or high viscosity.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional mixer for raw materials used in woven bag production, comprising a mixer body, a drive box mounted on the top of the mixer body, feed inlets on both sides of the top of the drive box, and a discharge pipe at the bottom of the mixer body; a drive motor mounted on the top of the drive box via a bracket, a first gear mounted on the output end of the drive motor via a rotating column, a second gear meshing with one side of the first gear, and a stirring column fixedly connected inside the second gear; and a stirring mechanism for multi-directional stirring of materials provided on the stirring column.
[0007] Furthermore, the stirring mechanism includes a triangular plate, a support column is rotatably connected inside the triangular plate, an internal gear is installed on the outer wall of the support column, and a ring gear is installed on the inner bottom wall of the drive box, with the internal gear and the ring gear meshing with each other.
[0008] Furthermore, an eccentric wheel is fixedly connected to the bottom end of the support column on the triangular plate, and an eccentric column is installed on one side of the bottom end of the eccentric wheel. A spiral stirring blade is installed on the outer wall of the eccentric column.
[0009] Furthermore, the stirring column is provided with an auxiliary mechanism for assisting in stirring the material. The auxiliary mechanism includes a fixing ring, which is fixedly connected to the outer wall of the stirring column. The outer wall of the fixing ring is rotatably connected to three sets of first connecting rods, and a scraper is installed at one end of each first connecting rod.
[0010] Furthermore, a threaded rod is rotatably connected inside the stirring column, and a reciprocating ring is threadedly connected to the bottom end of the outer wall of the threaded rod. A second connecting rod is rotatably connected to the side of the first connecting rod near the stirring column, and one end of each of the three sets of second connecting rods is rotatably connected to the reciprocating ring.
[0011] Furthermore, a support ring is fixedly connected to the bottom end of the outer wall of the stirring column, and stirring rods are arranged around the bottom of the support ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This multi-directional mixer for raw materials used in woven bag production uses a drive motor to rotate a first gear, which in turn causes a meshing second gear to rotate a stirring column. As the triangular plate rotates with the stirring column, the inner gear rolls on the ring gear, causing the eccentric wheel and eccentric column to move eccentrically. This allows the spiral stirring blades to perform multi-directional mixing of the materials. Combined with auxiliary mechanisms, the materials are mixed in multiple ways, ensuring that different raw materials are fully mixed and meeting the strict requirements for raw material uniformity in woven bag production.
[0014] Furthermore, as the fixed ring rotates with the mixing column, it drives the scraper to slide on the inner wall of the mixer body, promptly scraping off the attached material and preventing material accumulation from affecting mixing efficiency and equipment performance. By rotating the threaded rod, the reciprocating ring can move up and down, which in turn drives the first connecting rod to rotate via the second connecting rod, thereby adjusting the angle of the scraper. When cleaning is required, the scraper can be brought close to the inner wall for scraping; when cleaning is not required, the scraper can be moved away from the inner wall for auxiliary mixing. This not only effectively prevents material adhesion but also plays an important role in cleaning the equipment, extending its service life.
[0015] Furthermore, the support ring and stirring rod at the bottom of the stirring column stir the material at the bottom of the mixer, preventing material blockage at the discharge pipe and further improving the uniformity of material mixing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a multi-directional mixer for raw materials used in woven bag production, comprising a mixer body 1, a drive box 2 mounted on the top of the mixer body 1, feed inlets 3 on both sides of the top of the drive box 2, and a discharge pipe 4 at the bottom of the mixer body 1; a drive motor 5 mounted on the top of the drive box 2 via a bracket, a first gear 6 mounted on the output end of the drive motor 5 via a rotating column, a second gear 7 meshing with one side of the first gear 6, and a stirring column 8 fixedly connected inside the second gear 7; a stirring mechanism for multi-directional stirring of materials is provided on the stirring column 8; the stirring mechanism includes a triangular plate 9, a support column rotatably connected inside the triangular plate 9, an internal gear 10 mounted on the outer wall of the support column, a ring gear 11 mounted on the inner bottom wall of the drive box 2, the internal gear 10 and the ring gear 11 meshing with each other; an eccentric wheel 12 fixedly connected to the bottom end of the support column on the triangular plate 9, an eccentric column mounted on one side of the bottom end of the eccentric wheel 12, and a spiral stirring blade 13 mounted on the outer wall of the eccentric column.
[0025] When using the mixer, different raw materials are added into the mixer through the two feed ports 3 at the top of the drive box 2. Then, the drive motor 5 is started. After the drive motor 5 starts, its output end drives the first gear 6 to rotate through the rotating column. Figure 1 and Figure 2 As shown, since the first gear 6 and the second gear 7 mesh with each other, the rotation of the first gear 6 will drive the rotation of the second gear 7, as follows. Figure 3 and Figure 4 As shown, since the stirring column 8 is fixedly connected inside the second gear 7, the stirring column 8 will rotate together with the second gear 7. When the stirring column 8 rotates, the triangular plate 9 fixedly connected to the outer wall of the stirring column 8 will rotate synchronously, causing the stirring column 8 to drive the triangular plate 9 to rotate around the axis of the stirring column 8, as shown. Figure 3 and Figure 4 As shown, since an internal gear 10 is installed on the support column inside the triangular plate 9, and a ring gear 11 is installed on the inner bottom wall of the drive box 2, the internal gear 10 and the ring gear 11 mesh with each other. Therefore, when the triangular plate 9 rotates around the stirring column 8, the internal gear 10 rolls on the ring gear 11, causing the support column to rotate around its own axis. Figure 3 and Figure 4As shown, an eccentric wheel 12 is fixedly connected to the bottom end of the support column. Therefore, as the support column rotates, the eccentric column on one side of the bottom end of the eccentric wheel 12 also moves eccentrically. This causes the spiral stirring blades 13 installed on the outer wall of the eccentric column to stir the material in multiple directions under the drive of the eccentric movement. The spiral structure of the spiral stirring blades 13 can make the material move up and down and in the circumferential direction during the stirring process, which enhances the stirring effect.
[0026] Example 2: Please refer to Figure 5 and Figure 6 Based on Embodiment 1, an auxiliary mechanism is also disclosed, the specific structure of which is as follows:
[0027] The auxiliary mechanism includes a fixed ring 15, which is fixedly connected to the outer wall of the stirring column 8. Three sets of first connecting rods 16 are rotatably connected to the outer wall of the fixed ring 15, and a scraper 17 is installed at one end of the first connecting rod 16. A threaded rod 14 is rotatably connected inside the stirring column 8. A reciprocating ring 18 is threadedly connected to the bottom end of the outer wall of the threaded rod 14. A second connecting rod 19 is rotatably connected to the side of the first connecting rod 16 near the stirring column 8. One end of the three sets of second connecting rods 19 is rotatably connected to the reciprocating ring 18. A support ring 20 is fixedly connected to the bottom end of the outer wall of the stirring column 8. Stirring rods 21 are arranged around the bottom of the support ring 20.
[0028] When the stirring column 8 rotates, such as Figure 5 and Figure 6 As shown, since the fixed ring 15 is fixedly connected to the outer wall of the stirring column 8, the rotation of the stirring column 8 will drive the fixed ring 15 to rotate. The outer wall of the fixed ring 15 is rotatably connected to three sets of first connecting rods 16. A scraper 17 is installed at one end of each first connecting rod 16. Therefore, the scraper 17 will slide along the inner wall of the mixer body 1 as the fixed ring 15 rotates, scraping off the material adhering to the inner wall of the mixer body 1, preventing material accumulation and ensuring mixing effect. Figure 5 and Figure 6 As shown, since the internal rotating connection of the stirring column 8 is a threaded rod 14, when the threaded rod 14 is rotated, the reciprocating ring 18 connected to the bottom thread of its outer wall will reciprocate up and down on the threaded rod 14, as shown. Figure 5 and Figure 6As shown, the first connecting rod 16 is rotatably connected to the second connecting rod 19 on the side near the stirring column 8. One end of the three sets of second connecting rods 19 is rotatably connected to the reciprocating ring 18. The up-and-down movement of the reciprocating ring 18 drives the first connecting rod 16 to rotate through the second connecting rod 19, thereby adjusting the position of the scraper 17 to better adapt to different stirring needs. When it is necessary to clean the inner wall of the mixer body 1, the threaded rod 14 is rotated, which drives the reciprocating ring 18 to move downward, thereby causing the second connecting rod 19 and the first connecting rod 16 to rotate respectively, so that the scraper 17 gradually approaches the inner wall of the mixer body 1. When the stirring column 8 rotates, the scraper 17 is driven to scrape the inner wall of the mixer body 1. When cleaning is not required, the scraper 17 is gradually moved away from the inner wall of the mixer body 1. At this time, the scraper 17 rotates with the stirring column 8, which can assist in stirring the material. Figure 5 and Figure 6 As shown, since a support ring 20 is fixedly connected to the bottom of the outer wall of the stirring column 8, and stirring rods 21 are arranged around the bottom of the support ring 20, when the stirring column 8 rotates, the support ring 20 and the stirring rods 21 rotate accordingly. The stirring rods 21 stir the material at the bottom of the mixer body 1, further improving the mixing uniformity of the material and preventing the material from clogging at the discharge pipe 4.
