Description

Technical Field

[0001] The utility model relates to the technical field of fiber preparation, in particular to a premixing device for fiber preparation that avoids wet agglomeration during feeding. Background Technique

[0002] Fiber materials are structured materials formed by fibrous substances through textile processing techniques, and are usually also referred to as textile materials. The application history of fiber materials is quite long. Although there is no clear record indicating when this material originated, in ancient human trade, fiber materials have always occupied an important position, fully demonstrating the importance of fiber materials to human development. Natural fibers or synthetic fibers can be made into fiber papers or various textiles and directly used as insulating materials; or impregnated papers can be made by impregnating paper with a liquid medium and used as capacitor dielectrics and cable insulation; or after impregnating with an insulating resin and hot pressing, they can be rolled into insulating laminated products and rolled products for use as insulating materials; or impregnated with insulating paint to make insulating paint cloth, paint silk, etc. for electrical insulation. Natural inorganic fibers can be used alone or in combination with plant fibers or synthetic fibers as high-temperature insulation.

[0003] In the prior art, premixing is required before fiber preparation, but the mixing effect of conventional mixing devices is not good, and wet agglomeration is likely to occur during the mixing process. Wet agglomeration will lead to an increase in the bonding force between fibers, making it difficult for the fibers to disperse, thus affecting the uniformity and quality of the fibers. This non-uniformity will further affect key indicators such as the mechanical properties and heat resistance of fiber-reinforced materials. Wet agglomeration may also result in waste of raw materials because some materials may be forced to be discarded due to ineffective utilization. Content of the Utility Model

[0004] The purpose of the utility model is to provide a premixing device for fiber preparation that avoids wet agglomeration during feeding, so as to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, a premixing device for fiber preparation that avoids wet agglomeration during feeding provided by the utility model includes a tank body. A stirring assembly is installed inside the tank body. The stirring assembly includes a first connecting rod arranged inside the tank body. A first bevel gear is installed at the bottom end of the first connecting rod. A second connecting rod is installed in the middle of the first bevel gear. Third connecting rods are installed on both sides of the outer wall of the second connecting rod. Second bevel gears are installed at the two ends of the two third connecting rods away from each other. The second bevel gears are meshed with third bevel gears. A plurality of first support rods and second support rods are respectively installed on the outer walls of the first bevel gear and the third bevel gear. Stirring blades are installed at the bottom ends of the plurality of first support rods and second support rods. A rotating joint is installed at the bottom end of the second connecting rod. The rotating joint is rotatably connected to a fourth connecting rod. Three third support rods are installed at the bottom end of the fourth connecting rod. Support plates are installed at one ends of the three third support rods.

[0006] Furthermore, two support columns are installed at the top end of the tank body. The top ends of the two support columns are both connected with a box body. A pushing component is installed inside the box body. The pushing component includes a motor installed on the inner bottom wall of the box body. One end of the motor is installed with a rotating shaft. The end of the rotating shaft far away from the motor is fixedly connected with a pushing plate. The outer wall of the rotating shaft is rotatably connected with a first connecting rod. A stop block is installed on the outer wall of one side of the first connecting rod. The first connecting rod is rotatably connected with a second connecting rod. The second connecting rod is rotatably connected with a third connecting rod. A spring is sleeved outside the third connecting rod. The bottom end of the spring is fixedly connected with a slider. A sleeve is sleeved outside the spring.

[0007] Furthermore, a feed inlet and a discharge outlet are respectively installed on the outer wall of the tank body. Valves are installed at one ends of the feed inlet and the discharge outlet.

[0008] Furthermore, a control panel is installed on the outer wall of one side of the tank body. A plurality of control buttons are installed on the outer wall of the control panel.

[0009] Furthermore, a rotating motor is installed at the connection between the first connecting rod and the first bevel gear. The control panel is electrically connected with the rotating motor and the motor.

[0010] Furthermore, tooth teeth are arranged on the outer walls of the first bevel gear, the second bevel gear and the third bevel gear. The first bevel gear and the second bevel gear are meshed. The second bevel gear and the third bevel gear are meshed.

[0011] Furthermore, four support feet are installed at the bottom end of the tank body. The four support feet are rectangular at the bottom end of the tank body.

[0012] Furthermore, the outer wall of the slider abuts against the inner wall of the sleeve. The outer wall of the slider is slidably connected with the inner wall of the sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The positive and reverse rotation of the stirring component can provide greater shearing force to help the materials disperse and mix better. During the stirring process, the materials may form lumps or wet knots. The positive and reverse rotation can break these lumps, prevent the accumulation and blockage of the materials, and ensure the smooth operation of the stirring device. More efficient stirring means shorter mixing time, which helps to reduce the wet knot problem caused by long-time mixing. At the same time, more comprehensive contact also helps to disperse the moisture more evenly.

[0015] 2. The up-and-down movement of the pushing component provides additional power for the material, making it easier to be turned and mixed. The support plate increases the power source for turning and improves the turning efficiency. By utilizing the up-and-down movement of the support plate, the material can be turned more frequently in the vertical direction, which helps to break the agglomerates in the material and make the material finer and more uniform. When the support plate moves downward, it can turn up the material at the bottom and bring it into the mixing area; when the support plate moves upward, it can push the material at the top into the mixing area. This alternating up-and-down movement helps to prevent the material from forming dead corners or accumulation areas in the mixing barrel. Description of the Drawings

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 - Figure 5 , the present utility model provides a technical solution for a premixing device for fiber preparation to avoid wet agglomeration during feeding:

[0028] In the embodiments of the present utility model, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , including a tank body 1, a stirring assembly 2 is installed inside the tank body 1. The stirring assembly 2 includes a first connecting rod 201 arranged inside the tank body 1. A first bevel gear 202 is installed at the bottom end of the first connecting rod 201. A second connecting rod 203 is installed in the middle of the first bevel gear 202. Third connecting rods 204 are installed on both sides of the outer wall of the second connecting rod 203. Second bevel gears 205 are installed at the two ends of the two third connecting rods 204 away from each other. The second bevel gears 205 are meshed with third bevel gears 206. A plurality of first support rods 207 and second support rods 208 are respectively installed on the outer walls of the first bevel gear 202 and the third bevel gear 206. Stirring blades 209 are installed at the bottom ends of the plurality of first support rods 207 and second support rods 208. A rotating joint is installed at the bottom end of the second connecting rod 203. The rotating joint is rotatably connected to a fourth connecting rod 210. Three third support rods 211 are installed at the bottom end of the fourth connecting rod 210. Support plates 212 are installed at one ends of the three third support rods 211.

[0029] It should be noted that: when the first bevel gear 202 rotates forward, it will drive the two second bevel gears 205 to start rotating, and the two second bevel gears 205 will drive the third bevel gear 206 to rotate in the reverse direction.

[0030] Refer to Figure 5, two struts 3 are installed at the top end of the tank body 1. The top ends of the two struts 3 are both connected with a box body 4. A pushing assembly 5 is installed inside the box body 4. The pushing assembly 5 includes a motor 501 installed on the inner bottom wall of the box body 4. One end of the motor 501 is installed with a rotating shaft 502. The end of the rotating shaft 502 away from the motor 501 is fixedly connected with a push plate 503. The outer wall of the rotating shaft 502 is rotatably connected with a first connecting rod 504. A stop block 505 is installed on the outer wall of one side of the first connecting rod 504. The first connecting rod 504 is rotatably connected with a second connecting rod 506. The second connecting rod 506 is rotatably connected with a third connecting rod 507. A spring 508 is sleeved outside the third connecting rod 507. The bottom end of the spring 508 is fixedly connected with a slider 509. A sleeve 510 is sleeved outside the spring 508.

[0031] It should be noted that: when the spring 508 is compressed, it stores energy, and when released, it quickly converts the energy into power, which can provide more power for the pushing assembly 5.

[0032] Refer to Figure 1 , a feed inlet 6 and a discharge outlet 7 are respectively installed on the outer wall of the tank body 1. Valves are installed at one ends of the feed inlet 6 and the discharge outlet 7.

[0033] It should be noted that: the feed inlet 6 and the discharge outlet 7 are communicated with the inside of the tank body 1 by openings, and the valves can conveniently control the entry and exit of materials. By setting the valves, the flow of materials can be quickly cut off, avoiding the occurrence of similar accidents and improving the safety of the equipment.

[0034] Refer to Figure 1 , a control panel 8 is installed on the outer wall of one side of the tank body 1. A plurality of control buttons are installed on the outer wall of the control panel 8.

[0035] It should be noted that: through the control panel 8, the staff can complete the control and operation of the entire equipment in only one place without frequent movement or position switching. This centralized control method not only improves work efficiency but also reduces the possibility of operation errors.

[0036] Working principle: When the motor 501 is started with the control panel 8, the motor 501 drives the rotating shaft 502 to start rotating. The push plate 503 fixedly connected to the rotating shaft 502 will start to rotate simultaneously due to the rotation of the rotating shaft 502. Then, the first connecting rod 504 rotatably connected to the outer wall of the rotating shaft 502 will not rotate due to the rotation of the rotating shaft 502. However, the stopper 505 installed on the first connecting rod 504 will be in contact with the push plate 503 due to the rotation of the push plate 503. At the same time, the rotation of the push plate 503 drives the first connecting rod 504 to lift clockwise, and at the same time drives the third connecting rod 507 upward. The spring 508 sleeved outside the third connecting rod 507 contracts due to the upward displacement of the third connecting rod 507, and stores the contracting force at the same time. After the push plate 503 rotates to a certain extent and drops the stopper 505, the spring 508 stops being stressed and rebounds to drive the third connecting rod 507. The slider 509 installed at one end of the spring 508 slides down along the inner wall of the sleeve 510 to vibrate the inner bottom wall of the sleeve 510, so that the stirring assembly 2 can be lifted and vibrated to a certain extent at the same time. In this way, the reciprocating up and down movement can cover a larger area of the inner wall of the tank body 1, enabling the materials to be more comprehensively turned and mixed, effectively reducing the generation of accumulation and wet agglomeration, and maintaining the fluidity of the materials;

[0037] Meanwhile, the rotating motor at the connection between the first connecting rod 201 and the first bevel gear 202 starts to operate after being activated by the electrical connection of the control panel 8, driving the first bevel gear 202 to start rotating. Since the first bevel gear 202 is meshed with two second bevel gears 205, when the first bevel gear 202 starts to rotate, it drives the second bevel gears 205 to start rotating. When the two second bevel gears 205 rotate, they drive the third bevel gear 206 to rotate in the opposite direction. The outer walls of the first bevel gear 202 and the third bevel gear 206 are respectively connected with a first support rod 207 and a second support rod 208. The stirring blades 209 installed at the bottoms of the first support rod 207 and the second support rod 208 will rotate forward and backward simultaneously in the material. The forward rotation pushes the material towards the center, while the reverse rotation pushes the material outwards. Through the alternating forward and reverse rotation actions, the uniformity of mixing and stirring is effectively achieved, which helps to reduce the accumulation of moisture in local areas, thereby reducing the risk of wet agglomeration. And the alternating action of the forward and reverse rotation of the first support rod 207 and the second support rod 208 can effectively break up the already formed wet agglomerates and make them re-participate in the mixing process, thus avoiding the further deterioration of the wet agglomeration problem. The rotating joint installed at the bottom of the second connecting rod 203 is connected with the fourth connecting rod 210. A plurality of third support rods 211 installed at the bottom of the fourth connecting rod 210 are all equipped with support plates 212. When the pushing assembly 5 pushes the stirring assembly 2, the area of the support plates 212 is used to expand the action range of the stirring assembly 2, enabling it to reach a wider area inside the tank body 1. When the first connecting rod 201 expands and contracts vertically, the fourth connecting rod 210 also moves accordingly, bringing the materials at the bottom and top into the mixing area to prevent material wet agglomeration.
