Description

Technical Field

[0001] This utility model relates to the field of silicone rubber production technology, and in particular to a mixing device for silicone rubber production. Background Technology

[0002] Silicone rubber products are made from methyl vinyl silicone rubber as the base rubber, with the addition of various fillers (reinforcing agents, heat resistant agents, modifiers, etc.) through processes such as mixing, slurry blowing, filtration, vulcanization, molding, extrusion, and bonding. The production process of silicone rubber products requires mixing various raw materials such as powder, rubber, and silicone.

[0003] Chinese utility model patent CN215876998U discloses a liquid silicone rubber mixing device, including a supporting base column and a mixing tank. Four supporting base columns are arranged in parallel groups, and a mounting frame is fixedly mounted on the top of each column. An installation plate is fixedly mounted inside one side of the mounting frame, and a mounting pad is fixedly mounted on the upper part of the mounting plate. A motor is fixedly mounted on the upper part of the mounting pad, and a rotating ring is fixedly mounted on the upper part of the mounting pad. A sealing ring plate is fixedly mounted on one side wall of the mixing tank. A mounting base is located on the outer side of the bottom of each supporting base column. The output end of the motor is fixedly connected to a rotating shaft column, which passes through the rotating ring and the sealing ring plate and is rotatably mounted inside the mixing tank. A stirring bracket is fixedly mounted outside the rotating shaft column, located inside the mixing tank. Multiple stirring brackets are arranged in groups around the outside of the rotating shaft column, and a fan plate is fixedly mounted on the top of each stirring bracket. This liquid silicone rubber mixing device solves the problem of low mixing efficiency by using stirring brackets and fan plates for mixing.

[0004] The liquid silicone rubber mixing device disclosed in the above-mentioned utility model patent is in direct contact with the material and is stirred when the stirring bracket and fan plate are working. Since the material has a certain viscosity, it will adhere to the stirring bracket and fan plate. The stirring bracket and fan plate are fixed on the rotating shaft and are difficult to disassemble, which increases the difficulty of cleaning the mixing device after use. Moreover, the material remaining on the stirring bracket and fan plate will affect subsequent processing. Therefore, the existing mixing device is inconvenient to clean. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a mixing device for silicone rubber production, which is used to mix various raw materials such as powder, rubber, and silicone during the production of silicone rubber products.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3The mixing device for silicone rubber production includes a frame 1 and a mixing tank 2 mounted on the frame 1. The mixing tank 2 has an inlet 21 and a outlet 22 communicating with the internal space of the mixing tank 2. The material to be mixed is poured into the mixing tank 2 through the inlet 21, and the mixed material is discharged through the outlet 22. The mixing tank 2 is also equipped with a detachable cover plate 3 and a locking member 4 that cooperates with the cover plate 3. The cover plate 3 covers the opening of the inlet 21. The locking component 4 includes a locking seat 41 rotatably connected to the cover plate 3, a locking screw 42 disposed on the locking seat 41, and a locking pressure block 43 cooperating with the locking screw 42. The cover plate 3 is provided with a groove 31 for accommodating part of the locking screw 42, and the locking pressure block 43 abuts against the side of the cover plate 3 away from the mixing plate and presses the cover plate 3 onto the mixing tank 2. The rotation of the locking seat 41 can drive the locking screw 42 in and out of the groove 31, and the locking... After the screw 42 enters the groove 31, rotating the locking block 43 presses the cover plate 3 onto the mixing tank 2, thus fixing the cover plate 3 onto the mixing tank 2. To remove the cover plate 3, rotate the locking block 43 away from the cover plate 3 and operate the screw 42 to exit the groove 31. The cover plate 3 is equipped with a rotatable stirring rod 32 and a first driving component connected to the stirring rod 32. The rod 32 extends into the mixing tank 2 through the feed inlet 21, and multiple stirring paddles 34 are spaced apart along the circumference of the stirring rod 32. When the stirring rod 32 and the stirring paddles 34 rotate under the drive of the first driving member, they can agitate the material in the mixing tank 2 and accelerate the mixing of the material. The mixing tank 2 is also provided with a discharge valve 23 for controlling the opening or closing of the discharge port 22, and the discharge valve 23 is located at the discharge port 22 to facilitate the control of material discharge.

[0025] Specifically, the working process of the mixing device for silicone rubber production provided in this embodiment is as follows: First, the materials to be mixed are poured into the mixing tank 2 from the feed inlet 21. Then, the cover plate 3 is installed on the mixing tank 2. After the cover plate 3 is placed at the opening of the feed inlet 21, the locking seat 41 is rotated so that the locking screw 42 extends into the groove 31. Then, the locking block 43 is rotated so that the locking block 43 moves along the axial direction of the locking screw 42 and abuts against the cover plate 3 until the locking block 43 presses the cover plate 3 onto the mixing tank 2, thus fixing the position of the cover plate 3 on the mixing tank 2. When the cover plate 3 is installed on the mixing tank 2, the stirring rod 32 and the stirring paddle 34 extend into the mixing tank 2. After the cover plate 3 is installed, the first... The driving component rotates the stirring rod 32 and drives the stirring paddle 34 to stir the material in the mixing tank 2, thereby accelerating the mixing of the material. After the material is mixed, the discharge valve 23 is opened to discharge the mixed material. When it is necessary to clean the mixing device for silicone rubber production, first rotate the locking block 43 to move the locking block 43 away from the cover plate 3, and then rotate the locking seat 41 to make the locking screw 42 disengage from the groove 31. The cover plate 3 can then be removed from the mixing tank 2, and the stirring rod 32 and the stirring paddle 34 can be removed from the mixing tank 2. At this time, the inside of the mixing tank 2 and the stirring rod 32 and the stirring paddle 34 can be cleaned to reduce the material residue inside the mixing tank 2 and on the stirring rod 32 and the stirring paddle 34. The mixing device for silicone rubber production provided in this embodiment can be easily disassembled and cleaned, effectively reducing the amount of material remaining inside the mixing device after mixing. Furthermore, the mixing device for silicone rubber production is simple to disassemble and install, and easy to use.

[0026] like Figure 1 and Figure 3 As shown, at least two locking elements 4 are provided at circumferential intervals along the feed inlet 21 on the mixing tank 2, and multiple grooves 31 are provided on the cover plate 3 that correspond one-to-one with the locking screws 42. The multiple locking elements 4 on the mixing tank 2 engage with the cover plate 3 at different positions to ensure a secure fit between the cover plate 3 and the mixing tank 2, preventing the cover plate 3 from detaching from the mixing tank 2 during material mixing.

[0027] like Figure 1As shown, the cover plate 3 is also provided with a feed pipe 35, which passes through the cover plate 3 and communicates with the internal space of the mixing tank 2. The end of the feed pipe 35 away from the mixing tank 2 is provided with a detachable end cap 36. The feed pipe 35 is used to continue adding materials into the mixing tank 2 during the mixing process, so as to make the materials proportioned according to production needs. During the mixing process, the end cap 36 and the feed pipe 35 cooperate to seal the opening of the feed pipe 35, preventing material leakage from the feed pipe 35.

[0028] In this embodiment, the cover plate 3 is also provided with a handle 37, which is located on the side of the cover plate 3 away from the mixing tank 2. The handle 37 on the cover plate 3 is used to facilitate the lifting or carrying of the cover plate 3, so as to place the cover plate 3 on the mixing tank 2 or remove it from the mixing tank 2.

[0029] Please refer to Figure 1 and Figure 3 The first driving component includes a first motor 33, the output end of which cooperates with the stirring rod 32. The first motor 33 drives the stirring rod 32 to rotate, thereby causing the stirring paddle 34 to move and agitate the materials in the mixing tank 2 under the action of the stirring rod 32. Furthermore, the rotational speed of the stirring rod 32 and the stirring paddle 34 can be adjusted by controlling the rotational speed of the first motor 33 to meet the production needs of mixing various types of materials.

[0030] Please combine Figure 1 , Figure 3 and Figure 4The frame 1 is also provided with a rotatable rotating rod 5, a second driving component that is connected to the rotating rod 5, and a rotatable rotating seat 7. The rotating rod 5 is eccentrically provided with a spherical head 51, and the mixing tank 2 is provided with a spherical groove 24 that cooperates with the spherical head 51. The rotating seat 7 is provided with a rotatable support rod 71, and the end of the support rod 71 away from the rotating seat 7 is rotatably connected to the mixing tank 2. When the rotating rod 5 rotates under the drive of the second driving member, the rotating rod 5 drives the spherical head 51 to rotate around the rotation axis of the rotating rod 5. At this time, the spherical head 51 pulls the mixing tank 2 to swing back and forth. During the swinging process of the mixing tank 2, the support rod 71 rotates back and forth synchronously around the rotating seat 7, and the rotating seat 7 rotates back and forth on the frame 1. This keeps the position of the mixing tank 2 on the frame 1 stable. At the same time, shaking the mixing tank 2 accelerates the mixing of materials in the mixing tank 2, which helps to improve the uniformity of material mixing. Furthermore, the movement of the mixing tank 2 driven by the second driving member can tilt the mixing tank 2, thereby increasing the speed at which materials are discharged from the mixing tank 2 during the material discharge process and reducing the material residue in the mixing tank 2.

[0031] Specifically, the mixing tank 2 is provided with a detachable mounting cover 25, which is attached to the spherical head 51 and presses the spherical head 51 into the spherical groove 24. The cooperation between the mounting cover 25 and the mixing tank 2 keeps the spherical head 51 within the spherical groove 24, preventing it from detaching from the mixing tank 2 when the rotating rod 5 rotates, thus improving the structural stability of the mixing device for silicone rubber production.

[0032] like Figure 3 and Figure 4 As shown, the second driving component includes a second motor 6, the output end of which cooperates with the rotating rod 5. The second motor 6 drives the rotating rod 5 to rotate, causing the spherical head 51 to rotate. The movement of the spherical head 51 then causes the mixing tank 2 to swing on the frame 1, preventing material from accumulating at the bottom of the mixing tank 2 and causing uneven mixing.

[0033] In detail, the frame 1 is also provided with a mounting base 11, and the mounting base 11 has a mounting hole that mates with the rotating seat 7. The rotating seat 7 is rotatably connected to the frame 1 by mates with the mounting hole on the mounting base 11, so that the rotating seat 7 can rotate smoothly on the frame 1, thereby improving the stability of the mixing tank 2 during operation.

[0034] Please refer to Figure 1 and Figure 3The frame 1 is provided with multiple support legs 12 at intervals. Each support leg 12 includes an adjusting screw 13 and a support pad 14 connected to it. The frame 1 is provided with a threaded hole that mates with the adjusting screw 13. The bracket is used to support the frame 1 to keep the position of the frame 1 stable on the working surface. By rotating the adjusting screw 13 to adjust the length of the adjusting screw 13 extending out of the threaded hole, the frame 1 can be leveled to keep it horizontal and prevent the mixing device for silicone rubber production from tipping over during use.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
