Description

Technical Field

[0001] This application relates to the field of silicone processing technology, specifically to a raw material mixing device for silicone product manufacturing. Background Technology

[0002] Silicone products are a type of products made primarily from silicone rubber. They possess excellent high-temperature resistance, low-temperature resistance, chemical corrosion resistance, and insulation properties, and are widely used in medical, electronics, automotive, food, and household goods industries.

[0003] In the production of silicone, it is often necessary to mix various raw materials and additives. In the existing technology, when mixing raw materials, multiple materials are generally directly put into a mixing drum, and the mixing operation is carried out by using a drive motor to rotate the stirring component inside the mixing drum. However, in actual mixing, the stirring component inside the mixing drum always rotates and mixes in the same direction along the stirring mechanism. Since the raw materials are relatively viscous, the raw materials are swirled in the same direction after being stirred, and some of the outer raw materials adhere to the inner wall of the mixing drum and are not fully stirred, resulting in poor actual mixing effect. Therefore, this application proposes a raw material mixing device for silicone product production. Utility Model Content

[0004] The purpose of this application is to solve the problem that existing mixing devices rely solely on built-in mixing components for unidirectional mixing, resulting in poor mixing effect of raw materials. This application provides a raw material mixing device for silicone product manufacturing.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A raw material mixing device for silicone product manufacturing, comprising:

[0007] The mounting plate has vertical plates at both ends;

[0008] A mixing tank is horizontally rotatably positioned between two vertical plates. A material pipe is connected to the mixing tank. A stirring rod located inside the mixing tank is rotatably inserted through one of the vertical plates. A circular toothed ring is fixedly mounted on the mixing tank. A rotating shaft is rotatably inserted between the two vertical plates. A circular gear that meshes with the teeth of the circular toothed ring is fixedly mounted on the rotating shaft.

[0009] The drive mechanism is located on one of the vertical plates and is used to drive the stirring rod and the rotating shaft to rotate synchronously in opposite directions.

[0010] Furthermore, the drive mechanism includes a dual-axis motor mounted on one of the vertical plates, with transmission bevel gears fixed at both ends of the dual-axis motor. A first driven bevel gear and a second driven bevel gear are fixed on the stirring rod and the rotating shaft, respectively, and the first driven bevel gear and the second driven bevel gear mesh with the teeth of the two transmission bevel gears.

[0011] Furthermore, the stirring rod includes an inner rod and an outer tube that are coaxially rotatably arranged. The inner rod has a plurality of first stirring blades arranged in an array along its length direction. The outer tube has a plurality of support rods arranged in an annular distribution. The support rods have a plurality of second stirring blades arranged in an array along their length direction. There are two first driven bevel gears, which are respectively fixed on the inner rod and the outer tube and each meshes with one of the transmission bevel gears.

[0012] Furthermore, the longitudinal sections of both the first and second stirring blades are cross-shaped, and several second stirring blades are staggered with several first stirring blades.

[0013] Furthermore, the mounting plate is provided with four rectangularly distributed support seats, and support wheels are rotatably mounted on the support seats. All four support wheels roll and overlap with the mixing tank.

[0014] Furthermore, it also includes a base plate, one end of which is provided with a column, one end of which is hinged to the column, and the other end of which is hinged to the base plate with a hydraulic cylinder, and the mixing tank is provided with a discharge port at one end of the column.

[0015] Furthermore, a support column is provided at the end of the base plate away from the column, and the mounting plate overlaps on the support column.

[0016] Furthermore, the inner wall of the mixing tank is arrayed with several spiral plates arranged in a ring.

[0017] The beneficial effects of this application are as follows:

[0018] In this application, the mixing tank is horizontally rotated on two vertical plates. The stirring rod and the mixing tank are driven to rotate synchronously in opposite directions by the driving mechanism. When the stirring rod stirs the raw materials, the rotation of the mixing tank also drives the raw materials to rotate and flow. Under the action of the rotational stress of the inner and outer double layers with opposite rotation directions, the stirring effect of the raw materials is better. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown in one embodiment of this application, a raw material mixing device for silicone product manufacturing includes:

[0026] Mounting plate 1, with vertical plates 2 at both ends; mixing tank 3, horizontally rotatably positioned between the two vertical plates 2, with a cylinder fixed on one of the vertical plates 2, one end of the mixing tank 3 rotatably inserted into the cylinder of one of the vertical plates 2, and the other end rotatably passing through the other vertical plate 2, the mixing tank 3 is connected to a material pipe 4, preferably, the material pipe 4 is equipped with a valve, when the mixing tank 3 rotates so that the material pipe 4 is directly above, raw materials are added into the mixing tank 3 through the material pipe 4, when the mixing tank 3 rotates so that the material pipe 4 is directly below, the material pipe 4 can be used as a discharge pipe to discharge the raw materials, a stirring rod 5 rotatably passing through one of the vertical plates 2 and located inside the mixing tank 3, a toothed ring 6 fixed on the mixing tank 3, a rotating shaft 7 rotatably passing through between the two vertical plates 2, and a round gear 8 fixed on the rotating shaft 7 that meshes with the teeth of the toothed ring 6; The drive mechanism 9, mounted on one of the vertical plates 2, drives the stirring rod 5 and the rotating shaft 7 to rotate synchronously in opposite directions. When stirring the raw materials, the raw materials are added to the mixing tank 3. The drive mechanism 9 drives the stirring rod 5 and the rotating shaft 7 to rotate synchronously in opposite directions. When the stirring rod 5 rotates, it stirs the raw materials in the mixing tank 3. When the rotating shaft 7 rotates, the teeth of the sprocket 8 and the sprocket ring 6 mesh, thereby driving the mixing tank 3 to rotate. This means that when stirring the raw materials, the stirring rod 5 stirs the raw materials, and the mixing tank 3 itself rotates, with the two stirring in opposite directions. At the same time, although the raw materials are viscous, as the mixing tank 3 rotates, it drives the raw materials to rotate and flow, so that the rotational flow force and the stirring torque are opposite. With the help of the two opposing torques, the stirring effect of the raw materials is better.

[0027] like Figure 4As shown, in some embodiments, the drive mechanism 9 includes a dual-axis motor 901 mounted on one of the vertical plates 2. Both ends of the dual-axis motor 901 are fixed with transmission bevel gears 902. The stirring rod 5 and the rotating shaft 7 are respectively fixed with a first driven bevel gear 903 and a second driven bevel gear 904. The first driven bevel gear 903 and the second driven bevel gear 904 mesh with the teeth of the two transmission bevel gears 902. When the dual-axis motor 901 performs work, its two output shafts drive the two transmission bevel gears 902 to rotate synchronously. By having the two transmission bevel gears 902 mesh with the teeth of the first driven bevel gear 903 and the second driven bevel gear 904 respectively, the stirring rod 5 and the rotating shaft 7 are driven to rotate synchronously. It should be noted that the two transmission bevel gears 902 are arranged opposite to each other, thus achieving the effect of driving the stirring rod 5 and the rotating shaft 7 to rotate synchronously in opposite directions.

[0028] like Figure 2 and Figure 4 As shown, in some embodiments, the stirring rod 5 includes an inner rod 501 and an outer tube 502 coaxially rotatably arranged. A plurality of first stirring blades 503 are arrayed along the length of the inner rod 501. A plurality of support rods 504 arranged in a ring are arrayed on the outer tube 502. A plurality of second stirring blades 505 are arrayed along the length of the support rods 504. The number of first driven bevel gears 903 is two. Preferably, the two first driven bevel gears 903 are arranged opposite each other, and the two first driven bevel gears 903 are respectively fixed on the inner rod 501 and the outer tube 502 and are both... When the dual-shaft motor 901 is working, the transmission bevel gear 902 at one end of the motor meshes with the teeth of the two first driven bevel gears 903, thereby driving the inner rod 501 and the outer tube 502 to rotate synchronously in opposite directions. The inner rod 501 rotates forward, causing the first stirring blade 503 to stir the raw material in a forward rotation. The outer tube 502 drives several support rods 504 to rotate in reverse, thereby causing the second stirring blade 505 to stir the raw material in a reverse rotation. Under the stress of the two rotating stirring forces, the raw material is tangentially stirred, thereby further improving the stirring effect of the raw material.

[0029] like Figure 2 and Figure 3 As shown, in some embodiments, the longitudinal sections of the first stirring blade 503 and the second stirring blade 505 are both cross-shaped. A plurality of second stirring blades 505 are staggered with a plurality of first stirring blades 503. The cross-shaped structure of the first stirring blades 503 and the second stirring blades 505 makes the stirring effect on the raw materials better. The staggered distribution of the two makes the tangential area between them larger when they rotate in opposite directions, resulting in a better tangential stirring effect on the raw materials.

[0030] like Figure 1As shown, in some embodiments, the mounting plate 1 is provided with four rectangularly distributed support seats 10, and support wheels 11 are rotatably mounted on the support seats 10. All four support wheels 11 roll and overlap with the mixing tank 3. Since the raw material has a certain weight, by setting them on the support seats 10 and support wheels 11, the mixing tank 3 can be rotated and supported without affecting its normal rotation, thus ensuring its rotational stability.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a base plate 12 is also included. A column 13 is provided at one end of the base plate 12. One end of the mounting plate 1 is hinged to the column 13. A hydraulic cylinder 14 is hinged between the other end of the mounting plate 1 and the base plate 12. A discharge port is provided at one end of the column 13 of the mixing tank 3. Preferably, a valve is provided in the discharge port. With the support of the base plate 12 and the hydraulic cylinder 14, the mixing tank 3 is kept horizontal during mixing. After mixing is completed, the hydraulic cylinder 14 performs work, which drives the mounting plate 1 to rotate around the hinge, lifting the mixing tank 3 to an inclined state. At this time, the discharge port is located at the end with the lower inclination. Opening the valve allows the raw material to be discharged from the discharge port, making the discharge of the raw material faster and better.

[0032] like Figure 2 As shown, in some embodiments, a support column 15 is provided at the end of the base plate 12 away from the column 13, and the mounting plate 1 overlaps on the support column 15. Through the provided support column 15, the mixing tank 3 remains in a horizontal state during the mixing process, and the support column 15 supports it to enhance the support performance of the hydraulic cylinder 14 and ensure the stability of the mixing tank 3.

[0033] like Figure 3 As shown, in some embodiments, the inner wall of the mixing tank 3 is provided with a plurality of spiral plates 16 arranged in a ring. The spiral plates 16 improve the performance of the mixing tank 3 in driving the raw material flow when it rotates. At the same time, when the mixing tank 3 rotates, the spiral plates 16 also apply a horizontal thrust to the raw material, which improves the flow performance of the raw material in the mixing tank 3 and improves the mixing effect.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
