Description

Technical Field

[0001] This utility model relates to the field of fluororubber premixed adhesive technology, specifically to a fluororubber premixed adhesive reaction device. Background Technology

[0002] Fluororubber premix is ​​a premixed rubber with added vulcanizing agents / accelerators (bisphenol AF / BPP). The main component of fluororubber premix is ​​vinylidene fluoride / hexafluoropropylene copolymer, with a fluorine content of 66%. Because it contains vulcanizing agents / accelerators (bisphenol AF / BPP), mixing with a stirring device is required during the mixing process.

[0003] Existing mixing equipment mainly uses a rotating shaft to drive a stirring rod for mixing. In actual mixing, the dispersion effect of the raw materials is poor, and the raw materials are prone to settling at the bottom of the container. This makes it impossible to ensure that the raw materials are mixed evenly, which affects the mixing quality of fluororubber premixed rubber. Utility Model Content

[0004] The purpose of this invention is to provide a fluororubber premixed rubber reaction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fluororubber premixed rubber reaction device, comprising a base plate, a hydraulic rod provided on one side of the surface of the base plate, a horizontal plate provided on the top of the hydraulic rod, a main shaft rotatably mounted at the center of one end of the horizontal plate, and auxiliary shafts rotatably mounted on both sides of the end of the horizontal plate located on the main shaft.

[0006] The main shaft is fitted with a drive gear at one end above the horizontal plate, and the secondary shaft is fitted with a driven gear at one end above the horizontal plate. The driven gear meshes with the drive gear, and a servo motor that drives the drive gear to rotate is provided on the upper surface of the horizontal plate.

[0007] The main shaft has stirring rods evenly arranged along the circumference at its bottom, and the secondary shaft has a diffusion disk at its bottom, which is located above the stirring rods.

[0008] The bottom plate has a container on its surface corresponding to the position of the stirring rod, and the container is located directly below the stirring rod.

[0009] The main shaft includes an electro-hydraulic push rod rotatably mounted on the horizontal plate. The top of the electro-hydraulic push rod extends above the horizontal plate. The drive gear is sleeved on the top of the electro-hydraulic push rod. The bottom of the electro-hydraulic push rod is provided with a shaft, and the stirring rod is located at the bottom of the shaft.

[0010] The secondary shaft includes an outer cylinder rotatably mounted on the horizontal plate, the top of the outer cylinder extending above the horizontal plate, the driven gear sleeved on the top of the outer cylinder, an inner shaft slidably inserted inside the outer cylinder, and a diffuser disk disposed at the bottom of the inner shaft.

[0011] The inner shaft has a slider at one end inside the outer cylinder, and the outer cylinder has a groove on its side that cooperates with the slider.

[0012] A connecting plate is rotatably sleeved on the shaft. Through holes are opened on both sides of the connecting plate corresponding to the positions of the inner shaft. A bushing is installed in the through hole. The inner shaft is rotatably connected to the connecting plate through the bushing.

[0013] The diameter of the circle enclosed by the stirring rod is smaller than the inner diameter of the container.

[0014] The shaft is located at the center between the two inner shafts, and the edge of the diffuser disk does not contact the outer wall of the shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a servo motor to drive the drive gear to rotate. The drive gear, in conjunction with the driven gear, simultaneously drives the main shaft and the secondary shaft to rotate, thereby causing the stirring rod and the diffusion plate to rotate within the container. The stirring rod stirs the fluororubber premixed material from below, while the diffusion plate stirs and diffuses the fluororubber premixed material from above. This facilitates the uniform mixing of the fluororubber premixed material by the stirring rod below, resulting in a more uniform mixture and improved mixing quality. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a fluororubber premixed rubber reaction device, including a base plate 10, a hydraulic rod 20 on one side of the surface of the base plate 10, a horizontal plate 30 on the top of the hydraulic rod 20, a main shaft 50 rotatably mounted at the center of one end of the horizontal plate 30, and a secondary shaft 60 rotatably mounted on both sides of the end of the horizontal plate 30 located above the main shaft 50; a drive gear 54 is sleeved on the end of the main shaft 50 above the horizontal plate 30, and a driven gear 66 is sleeved on the end of the secondary shaft 60 above the horizontal plate 30, the driven gear 66 meshing with the drive gear 54; a servo motor 31 for driving the drive gear 54 to rotate is provided on the upper surface of the horizontal plate 30; stirring rods 53 are evenly arranged along the circumferential direction at the bottom of the main shaft 50, and a diffuser disk 65 is provided at the bottom of the secondary shaft 60, located above the stirring rods 53; a container 40 is provided on the surface of the base plate 10 corresponding to the position of the stirring rods 53, and the container 40 is located directly below the stirring rods 53.

[0025] Specifically, the raw materials of the fluororubber premix are added to the container 40. Then, the servo motor 31 drives the drive gear 54 to rotate. The drive gear 54 and the driven gear 66 work together to drive the main shaft 50 and the secondary shaft 60 to rotate, thereby driving the stirring rod 53 and the diffusion disk 65 to rotate inside the container 40. The stirring rod 53 stirs the fluororubber premix raw materials from below, and the diffusion disk 65 stirs and diffuses the fluororubber premix from above. This facilitates the uniform mixing of the fluororubber premix raw materials by the stirring rod 53 below, resulting in a more uniform mixture and improved mixing quality of the fluororubber premix.

[0026] The position of the horizontal plate 30 can be adjusted by the hydraulic rod 20. When it is necessary to stir and mix the fluororubber premixed raw materials in the container 40, the hydraulic rod 20 drives the horizontal plate 30 to move downward, thereby driving the main shaft 50 and the auxiliary shaft 60 to move downward simultaneously, so that the stirring rod 53 and the diffusion plate 65 are inserted into the fluororubber premixed raw materials in the container 40, which facilitates the stirring and mixing of the fluororubber premixed raw materials. After the fluororubber premixed raw materials are stirred and mixed, the hydraulic rod 20 pushes the horizontal plate 30 to move upward, thereby driving the main shaft 50 and the auxiliary shaft 60 to move upward, and at the same time driving the stirring rod 53 and the diffusion plate 65 to move upward, so that the stirring rod 53 and the diffusion plate 65 are separated from the container 40, making it easy to take out the mixed fluororubber premixed raw materials from the container 40.

[0027] The main shaft 50 includes an electro-hydraulic push rod 51 rotatably mounted on a horizontal plate 30. The top of the electro-hydraulic push rod 51 extends above the horizontal plate 30. A drive gear 54 is sleeved on the top of the electro-hydraulic push rod 51. A shaft 52 is provided at the bottom of the electro-hydraulic push rod 51. A stirring rod 53 is located at the bottom of the shaft 52. The electro-hydraulic push rod 51 can drive the shaft 52 to move up and down, thereby pushing the stirring rod 53 to move up and down. This facilitates the adjustment of the depth of the stirring rod 53 in the fluororubber premixed raw material in the container 40, making it easier to stir and mix fluororubber premixed raw materials at different depths, thus improving the mixing efficiency of the fluororubber premixed raw material.

[0028] The secondary shaft 60 includes an outer cylinder 61 rotatably mounted on a horizontal plate 30. The top of the outer cylinder 61 extends above the horizontal plate 30. A driven gear 66 is sleeved on the top of the outer cylinder 61. An inner shaft 62 is slidably inserted inside the outer cylinder 61. A diffuser disk 65 is disposed at the bottom of the inner shaft 62. By cooperating with the inner shaft 62 and the outer cylinder 61, the length of the secondary shaft 60 can be adjusted, thereby adjusting the depth of the diffuser disk 65 in the fluororubber premixed raw material.

[0029] The inner shaft 62 is provided with a slider 63 at one end inside the outer cylinder 61, and a groove 64 that cooperates with the slider 63 is provided on the side of the outer cylinder 61. The inner shaft 62 can slide along the outer cylinder 61 by the cooperation of the slider 63 and the groove 64, thereby adjusting the length of the secondary shaft 60.

[0030] A connecting plate 70 is rotatably sleeved on the shaft 52. Through holes are opened on both sides of the connecting plate 70 corresponding to the positions of the inner shaft 62. A bushing is installed in the through hole. The inner shaft 62 is rotatably connected to the connecting plate 70 through the bushing. When the electric hydraulic push rod 51 is working, the electric hydraulic push rod 51 drives the shaft 52 to move, thereby adjusting the stirring height of the stirring rod 53. At the same time, the shaft 52 drives the inner shaft 62 to move along the outer cylinder 61 through the connecting plate 70, thereby adjusting the depth of the diffuser 65 in the fluororubber premixed raw material.

[0031] Specifically, when mixing the fluororubber premixed raw materials in container 40, the electric hydraulic push rod 51 continuously drives the shaft 52 to move up and down reciprocally. At the same time, the shaft 52 drives the inner shaft 62 to move up and down along the outer cylinder 61 through the connecting plate 70, thereby driving the stirring rod 53 and the diffusion plate 65 to move up and down reciprocally in the fluororubber premixed raw materials and rotate and stir, which accelerates the dispersion and mixing of the fluororubber premixed raw materials.

[0032] The diameter of the circle enclosed by the stirring rod 53 is smaller than the inner diameter of the container 40, so as to avoid the stirring rod 53 colliding with the inner wall of the container 40 when the main shaft 50 drives the stirring rod 53 to rotate.

[0033] The shaft 52 is located at the center between the two inner shafts 62, and the edge of the diffuser disk 65 does not contact the outer wall of the shaft 52. When the secondary shaft 60 drives the diffuser disk 65 to rotate, the diffuser disk 65 is prevented from colliding with the secondary shaft 52.

[0034] Working principle: In use, the raw material of fluororubber premix is ​​added to container 40. The hydraulic rod 20 drives the horizontal plate 30 to move downward, thereby driving the main shaft 50 and the auxiliary shaft 60 to move downward synchronously. This allows the stirring rod 53 and the diffusion plate 65 to be inserted into the fluororubber premix raw material in container 40. Then, the servo motor 31 drives the drive gear 54 to rotate. The drive gear 54 and the driven gear 66 cooperate to drive the main shaft 50 and the auxiliary shaft 66 to rotate, thereby driving the stirring rod 53 and the diffusion plate 65 to rotate in container 40. The stirring rod 53 stirs the fluororubber premix raw material from below, and the diffusion plate 65 stirs and diffuses the fluororubber premix from above, making it easier for the stirring rod 53 to evenly mix the fluororubber premix raw material together. The raw material is evenly mixed.

[0035] Meanwhile, as the stirring rod 53 and the diffusion disk 65 rotate, the electric hydraulic push rod 51 continuously drives the shaft 52 to move up and down reciprocally. At the same time, the shaft 52 drives the inner shaft 62 to move up and down along the outer cylinder 61 through the connecting plate 70, thereby driving the stirring rod 53 and the diffusion disk 65 to move up and down reciprocally in the fluororubber premixed raw material and rotate and stir, which accelerates the dispersion and mixing of the fluororubber premixed raw material.

[0036] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
