[0001] This invention relates to the field of filter manufacturing technology, and in particular to an oil filter housing sealing device and sealing method. Background Technology

[0002] During the manufacturing process of oil filters, it is necessary to seal the edges at the connection between the oil filter housing and the end cap. Existing housing sealing devices can only seal filter housings of a single diameter. When sealing filter housings of different sizes is required, it is necessary to replace them with suitable housing sealing devices, which is troublesome and has a high purchase cost.

[0003] In view of this, the inventors of this application have invented an oil filter housing sealing device and sealing method. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an oil filter housing sealing device.

[0005] This invention solves the above-mentioned technical problems through the following technical means: an oil filter housing sealing device, including an installation groove, a lifting frame, a rotating component, a rotating cylinder, an installation cylinder, a rack, a motor, and a roller assembly. The installation cylinder is fixed above the operating table, and the top surface of the operating table is recessed downward to form an installation groove. Several racks are circumferentially inserted through the installation cylinder, with one end of each rack extending through the installation groove into the installation cylinder. A roller assembly is fixed at one end of the rack in the installation cylinder. The roller assembly presses the surface of the filter housing and the end cap connection. The lifting frame is fixed to the top surface of the operating table, and the rotating component is fixed to the top surface of the lifting frame. The drive end of the rotating component passes through the lifting frame and is fixed to the rotating cylinder. The bottom opening of the rotating cylinder is located directly above the area formed by the enclosed area of ​​several roller assemblies.

[0006] An internal gear ring is rotatably connected to the outer wall of the mounting groove. The rack is partially meshed with a gear in the mounting groove. The gear also meshes with the internal gear ring. A motor is fixed in the mounting groove. The rotating end of the motor meshes with any one of the gears.

[0007] Furthermore, the roller assembly includes a roller and a mounting bracket, the mounting bracket being fixed to one end of the rack located inside the mounting cylinder; the roller is vertically rotatably connected inside the mounting bracket.

[0008] Furthermore, the top edge of the roller is a slope.

[0009] Furthermore, a support turntable is provided within the area enclosed by several of the rollers. The support turntable is rotatably connected to the bottom of the mounting cylinder, and the top surface of the support turntable is on the same horizontal plane as the lowest end of the roller.

[0010] Furthermore, the lifting frame includes a cylinder and a top plate. The top plate is located above the mounting cylinder. Cylinders are provided on both sides of the bottom surface of the top plate. The bottom end of the cylinder is fixed to the top surface of the operating table, and the telescopic end of the cylinder is fixed to the bottom surface of the cylinder.

[0011] Furthermore, the rotating assembly includes a rotating motor and a drive shaft. The rotating motor is fixed to the top surface of the cylinder, and the drive shaft is fixed to the drive end of the rotating motor. The bottom end of the drive shaft extends downward through the cylinder and is fixed to the top surface of the rotating drum.

[0012] A sealing method for an oil filter housing sealing device, the method comprising:

[0013] Step 1: Adjust the size of the enclosed area of ​​several rollers according to the diameter of the filter. When it is necessary to reduce the enclosed area of ​​several rollers, start the motor in the forward direction. The motor drives the internal gear ring to move into the mounting cylinder through the gear. The rack drives the rollers to gradually approach through the mounting bracket. After adjusting the enclosed area of ​​several rollers to the appropriate size, turn off the motor. When it is necessary to increase the enclosed area of ​​several rollers, start the motor in the reverse direction.

[0014] Step 2: Outer edge retraction. Place the filter end plate horizontally on the inclined surface of the rollers. The inclined surfaces of several rollers limit and position the filter end plate. Then, place the filter housing horizontally on the end plate. Start the cylinder. The cylinder drives the top plate to descend, and the top plate drives the rotating drum to descend, so that the top of the filter is embedded in the rotating drum. The rotating drum squeezes the filter housing downward. As the filter housing moves downward, the filter housing squeezes the outer edge of the end plate upward and retracts.

[0015] Step 3: Sealing the edges. Start the rotary motor. The rotary motor drives the drum to rotate through the drive shaft. The filter housing rotates with the drum under pressure. At the same time, the rotation of the filter housing drives the end plate to rotate. Under the continuous and seamless pressure of the drum, the end plate is brought up and pressed tightly against the outer wall of the filter housing, completing the sealing operation. Then, the cylinder is reset, which drives the drum to reset, and the filter is removed.

[0016] The beneficial effects of this invention are:

[0017] This invention relates to an oil filter housing sealing device. The size of the enclosed area of ​​several rollers can be adjusted according to the diameter of the filter. When it is necessary to reduce the size of the enclosed area of ​​several rollers, the motor is started in the forward direction. The motor drives the internal gear ring to move into the mounting cylinder via gears. The rack drives the rollers to gradually approach each other through the mounting frame. After adjusting the enclosed area of ​​several rollers to a suitable size, the motor is turned off. The sealing device can seal the edges of oil filter housings of different diameters. It is simple to operate and reduces the cost for companies to purchase housing sealing devices. Attached Figure Description

[0026] Please see Figure 1As shown, the oil filter housing sealing device described in this embodiment includes an installation groove 100, a lifting frame 20, a rotating component 30, a rotating drum 40, an installation cylinder 50, a rack 60, a motor 70, a roller assembly 80, and a linkage component 90. The installation cylinder 50 is fixed above the operating table 10. The operating table 10 is hollow inside and has at least an opening at the top. The top surface of the installation cylinder 50 is recessed downward to form the installation groove 100. The rack 60 passes through the installation cylinder 50 at equal intervals. One end of the rack 60 extends through the installation groove 100 into the installation cylinder 50. The roller assembly 80 is fixed at one end of the rack 60 in the installation cylinder 50. The roller assembly 80 presses the surface of the filter housing and the end cap connection. The lifting frame 20 is fixed on the top surface of the operating table 10. The rotating component 30 is fixed on the top surface of the lifting frame 20. The driving end of the rotating component 30 passes through the lifting frame 20 and is fixed to the rotating drum 40. The bottom opening of the rotating drum 40 is located directly above the area formed by the enclosed area of ​​several roller assemblies 80.

[0027] Please see Figure 3 As shown, an internal gear ring 901 is rotatably connected to the outer wall of the mounting groove 100. A gear 902 is partially meshed with the rack 60 inside the mounting groove 100. The gear 902 also meshes with the internal gear ring 901. The height of the gear 902 is greater than the distance between the rack 60 and the internal gear ring 901 so that the gear 902 can mesh with both the rack 60 and the internal gear ring 901 at the same time. A motor 70 is fixed inside the mounting groove 100. The rotating end of the motor 70 meshes with any one of the gears 902.

[0028] Please see Figure 2 , Figure 3 As shown, the roller assembly 80 includes a roller 801 and a mounting frame 802. The mounting frame 802 is fixed to one end of the rack 60 located inside the mounting cylinder 50. The mounting frame 802 is U-shaped, and the roller 801 is vertically rotatably connected inside the mounting frame 802. The top edge of the roller 801 is beveled. The beveled surface facilitates the insertion of the filter housing 1 and the end cap into the area formed by the enclosed area of ​​several rollers 801.

[0029] A support turntable 110 is provided in the area formed by several rollers 801. The support turntable 110 is rotatably connected to the bottom of the mounting cylinder 50. The top surface of the support turntable 110 is on the same horizontal plane as the bottom of the rollers 801. In this way, when the end cover of the filter 1 is rotated and sealed, the end cover does not detach from the surface of the rollers 801, which can improve the sealing efficiency.

[0030] Please see Figure 1 As shown, the lifting frame 20 includes a cylinder 201 and a top plate 202. The top plate 202 is located above the mounting cylinder 50. Cylinders 201 are provided on both sides of the bottom surface of the top plate 202. The bottom end of the cylinder 201 is fixed to the top surface of the operating table 10, and the telescopic end of the cylinder 201 is fixed to the bottom surface of the cylinder 201.

[0031] The rotating assembly 30 includes a rotating motor 301 and a drive shaft 302. The rotating motor 301 is fixed to the top surface of the cylinder 201, and the drive shaft 302 is fixed to the drive end of the rotating motor 301. The bottom end of the drive shaft 302 extends downward through the cylinder 201 and is fixed to the top surface of the rotating drum 40.

[0032] In use, first adjust the size of the area enclosed by several rollers 801 according to the diameter of filter 1. When it is necessary to reduce the area enclosed by several rollers 801, start motor 70 in the forward direction. Motor 70 drives internal gear ring 901 to move into mounting cylinder 50 through gear 902. The rack 60 drives rollers 801 to gradually approach through mounting bracket 802. After adjusting the area enclosed by several rollers 801 to a suitable size, turn off motor 70. When it is necessary to increase the area enclosed by several rollers 801, start motor 70 in the reverse direction.

[0033] Then, the end plate of filter 1 is placed horizontally on the inclined surface of roller 801. The inclined surfaces of several rollers 801 limit and position the end plate of filter 1. Then, the housing of filter 1 is placed horizontally on the end plate. The cylinder 201 is activated, which drives the top plate 202 to descend. The top plate 202 drives the rotating drum 40 to descend, so that the top of filter 1 is embedded in the rotating drum 40. The rotating drum 40 squeezes the housing of filter 1 downward. When the housing of filter 1 moves downward, the housing of filter 1 squeezes the end plate. The outer edge is brought together upwards; then the rotary motor 301 is started, and the rotary motor 301 drives the rotating drum 40 to rotate through the drive shaft 302. The filter housing 1 rotates with the rotating drum 40 under the pressure of the rotating drum 40. The rotation of the filter housing 1 drives the end plate to rotate at the same time. Under the continuous pressure of the roller 801 without dead angle, the end plate is pressed tightly against the outer wall of the filter housing 1, completing the sealing operation; then the cylinder 201 is reset, which drives the rotating drum 40 to reset, and the filter 1 can be removed.
