Description

Technical Field

[0001] This invention relates to an automatic sealing ring cutting and bonding machine and its cutting and bonding method, and particularly to the field of sealing ring manufacturing technology. Background Technology

[0002] Sealing rings are widely used in pressure vessels, power equipment, and pulse power drive sources, mainly for oil, gas and water isolation. For large-sized sealing rings, the use of molds increases costs, and multiple large-sized sealing rings cannot be formed in one production run. Most sealing rings are bonded with 90°, 30° or 45° angles.

[0003] Traditionally, large-size sealing rings are bonded manually or with the aid of tooling. Manual bonding makes it difficult to guarantee the quality of the sealing surface. Tooling requires the cooperation of personnel and equipment to bond the sealing rings, but only one sealing ring can be placed at a time. Furthermore, it cannot automatically adjust the length according to the size of the sealing ring to achieve the required bonding length. Summary of the Invention

[0004] Purpose of the invention: One purpose is to provide an automatic sealing ring cutting and bonding machine to solve the above-mentioned problems existing in the prior art; a further purpose is to provide an automatic sealing ring cutting and bonding method.

[0005] Technical solution: An automatic sealing ring cutting and bonding machine, comprising:

[0006] A frame, a fixed plate mounted on the frame, a first side plate and a second side plate mounted on both sides of the fixed plate, and a rotating plate mounted inside the fixed plate;

[0007] The rotating disk has a fixed wheel and a movable wheel on one side of the first side plate. A first cylinder is mounted on the rotating disk on one side of the fixed wheel. A pressure plate is provided at the output end of the first cylinder. The rotating disk has a lead screw that meshes with the movable wheel.

[0008] The first side plate is provided with a second cylinder, the second side plate is provided with a third cylinder and a sector gear, the output ends of the second cylinder and the third cylinder are provided with clamping plates, the sector gear is provided with a fourth cylinder at the point where it passes through the fixed plate, and the output end of the fourth cylinder is provided with an adhesive plate;

[0009] Both the fixed wheel and the movable wheel have multiple grooves. The fixed wheel has a cutting groove at the groove, and a cutting blade is provided in the cutting groove. The cutting blade is connected to a movable cylinder set in the fixed wheel. The fixed wheel has air intake holes on both sides of the cutting groove.

[0010] In a further embodiment, the rotating disk is rotatably connected to the fixed disk, and the rotating disk is also provided with a gear ring, which meshes with a first motor disposed on the fixed disk.

[0011] In a further embodiment, both the pressing plate and the adhesive plate are provided with slots that fit with the groove clearance.

[0012] In a further embodiment, the lead screw is movably connected to the rotating disk, and the rotating disk has a through hole at the meshing point between the lead screw and the movable wheel; one end of the lead screw is provided with a second motor mounted on the rotating disk.

[0013] In a further embodiment, the first side plate and the second side plate are parallel to each other, a first electric rail is provided between the second cylinder and the first side plate, a second electric rail is provided between the third cylinder and the second side plate, and the clamping plate of the third cylinder passes through the fixed plate and the fixed plate has a through hole.

[0014] In a further embodiment, the sector gear meshes with a third motor mounted on the second side plate, and the fixed plate has an arc-shaped hole at the connection between the sector gear and the fourth cylinder.

[0015] In a further embodiment, the groove is connected to the blade groove, the cutter is placed in the groove, and the air intake hole is connected to the air intake pipe.

[0016] An automatic cutting and bonding method for sealing rings includes the following steps:

[0017] Step 1: First, the third cylinder clamps multiple sealing strips in production. The second cylinder moves to the position where the third cylinder clamps the sealing strips and clamps them. At this time, the third cylinder releases the clamped sealing strips. The second cylinder moves along the direction of the first electric guide rail. When it moves to the set position, the first cylinder moves the clamping plate so that multiple sealing strips are located in the groove.

[0018] Step 2: The suction hole adsorbs the front section of the sealing strip to make the sealing strip fit into the groove. At this time, the second cylinder releases the clamped sealing strip. Then, according to the size of the sealing ring, the distance between the movable wheel and the fixed wheel is adjusted by rotating the screw. After the distance is adjusted, the first motor drives the rotating disk to rotate. During the rotation, the second cylinder resets and waits for the sealing strip to be clamped again. After the rotating disk rotates one revolution, when one side of the fixed wheel is parallel to one side of the first side plate and the knife groove is aligned with the fourth cylinder, the fourth cylinder moves the adhesive plate to contact the sealing strip. Then, the suction hole adsorbs the rear section of the sealing strip to make the sealing strip fit into the groove.

[0019] Step 3: After the sealing strip is attached to the groove, the moving cylinder drives the cutter to cut the sealing strip placed in the groove. Before cutting, the third cylinder clamps the sealing strip. After cutting, the third motor drives the sector gear to rotate. At this time, the fourth cylinder drives the bonding plate to move along the radial direction of the fixed wheel to cover the cut part of the sealing strip and heat and bond it. After bonding is completed, the fourth cylinder resets. When the fixed plate rotates to the second winding position, the first cylinder resets and the bonded sealing ring is taken out.

[0020] Beneficial Effects: This invention proposes an automatic sealing ring cutting and bonding machine and its cutting and bonding method. Through the cross-operation of the second and third cylinders, the prepared sealing strip is transferred to the groove. Under the movement of the first cylinder, the pressing plate places the sealing strip in the groove, and the suction hole causes the sealing strip to adhere to the groove. The rotation of the lead screw adjusts the distance between the movable wheel and the fixed wheel, satisfying the winding and bonding of sealing rings of different lengths. When the fixed wheel rotates once on the rotating disk and one side of the fixed wheel is parallel to one side of the first side plate, the cutting groove aligns with the fourth cylinder. The fourth cylinder moves the bonding plate to contact the sealing strip, and then the movable cylinder drives the cutter to cut the sealing strip. After cutting, the third motor drives the sector gear to rotate. At this time, the fourth cylinder drives the bonding plate to move radially along the fixed wheel, covering and heating the cut part of the sealing strip for bonding. After bonding, the fourth cylinder resets, and the first cylinder resets when the fixed plate rotates to the second winding position, removing the bonded sealing ring. This achieves automatic winding and bonding of sealing rings, as well as adjustment of different lengths. Attached Figure Description

[0031] The applicant argues that existing large-size sealing rings are all bonded manually or with the aid of tooling. Manual bonding makes it difficult to guarantee the quality of the sealing surface; tooling requires the cooperation of personnel and equipment to bond the sealing rings, and only one sealing ring can be placed at a time. Furthermore, it cannot automatically adjust the length according to the size of the sealing ring and achieve bonding of different lengths.

[0032] To address the problems existing in the prior art, this invention provides an automatic sealing ring cutting and bonding machine and its cutting and bonding method, which can meet the requirements for winding and bonding sealing rings of different lengths.

[0033] The present solution will be further described in detail below through embodiments and with reference to the accompanying drawings.

[0034] In this application, we propose an automatic sealing ring cutting and bonding machine and a method thereof, wherein the automatic sealing ring cutting and bonding machine includes:

[0035] The machine includes a frame 1, a fixed disk 2 mounted on the frame 1, a first side plate 21 and a second side plate 22 mounted on both sides of the fixed disk 2, and a rotating disk 3 mounted inside the fixed disk 2; the rotating disk 3 is rotatably connected to the fixed disk 2, and the rotating disk 3 is also provided with a gear ring, which meshes with a first motor 32 mounted on the fixed disk 2; the rotating disk 3 has a through hole at the meshing point of the lead screw 51 and the movable wheel 5.

[0036] The rotating disk 3 is provided with a fixed wheel 4 and a movable wheel 5 on one side of the first side plate 21. A first cylinder 31 is provided on one side of the fixed wheel 4 and mounted on the rotating disk 3. A pressure plate 231 is provided at the output end of the first cylinder 31. Both the pressure plate 231 and the adhesive plate 311 are provided with slots that fit with the groove 41 with clearance. A lead screw 51 is provided on the rotating disk 3 and meshes with the movable wheel 5. The lead screw 51 is movably connected to the rotating disk 3. A second motor is provided at one end of the lead screw 51 and mounted on the rotating disk 3.

[0037] The first side plate 21 is provided with a second cylinder 211, and the second side plate 22 is provided with a third cylinder 221 and a sector gear 222. The output ends of the second cylinder 211 and the third cylinder 221 are provided with clamping plates. The sector gear 222 passes through the fixed plate 2 and is provided with a fourth cylinder 23. The output end of the fourth cylinder 23 is provided with an adhesive plate 311. The first side plate 21 and the second side plate 22 are parallel to each other. A first electric rail is provided between the second cylinder 211 and the first side plate 21. A second electric rail is provided between the third cylinder 221 and the second side plate 22. The clamping plate of the third cylinder 221 passes through the fixed plate 2 and the fixed plate 2 has a through hole.

[0038] Both the fixed wheel 4 and the movable wheel 5 are provided with multiple grooves 41. The fixed wheel 4 is provided with a blade groove 42 at the groove 41. A cutter is provided in the blade groove 42. The cutter is connected to a movable cylinder provided in the fixed wheel 4. The fixed wheel 4 is provided with air intake holes 43 on both sides of the blade groove 42. The groove 41 is connected to the blade groove 42. The cutter is placed in the groove 41. The air intake holes 43 are connected to an air intake pipe.

[0039] The sector gear 222 meshes with the third motor 223 mounted on the second side plate 22, and the fixed plate 2 has an arc-shaped hole at the connection between the sector gear 222 and the fourth cylinder 23.

[0040] An automatic cutting and bonding method for sealing rings includes the following steps:

[0041] Step 1: First, the third cylinder 221 clamps multiple sealing strips in production. The second cylinder 211 moves to the position where the third cylinder 221 clamps the sealing strips and clamps them. At this time, the third cylinder 221 releases the clamped sealing strips. The second cylinder 211 moves along the direction of the first electric guide rail. When it moves to the set position, the first cylinder 31 moves the pressing plate 231 so that the multiple sealing strips are located in the groove 41.

[0042] Step 2: The suction hole 43 adsorbs the front part of the sealing strip to make the sealing strip fit with the groove 41. At this time, the second cylinder 211 releases the clamped sealing strip. Then, according to the size of the sealing ring, the distance between the movable wheel 5 and the fixed wheel 4 is adjusted by rotating the screw 51. After the distance is adjusted, the first motor 32 drives the rotating disk 3 to rotate. During the rotation, the second cylinder 211 resets and waits for the sealing strip to be clamped again. After the rotating disk 3 rotates one revolution, and one side of the fixed wheel 4 is parallel to one side of the first side plate 21 and the knife groove 42 is aligned with the fourth cylinder 23, the fourth cylinder 23 moves the adhesive plate 311 to contact the sealing strip. Then, the suction hole 43 adsorbs the rear part of the sealing strip to make the sealing strip fit with the groove 41.

[0043] Step 3: After the sealing strip is attached to the groove 41, the moving cylinder drives the cutter to cut the sealing strip placed in the groove 41. Before cutting, the third cylinder 221 clamps the sealing strip. After cutting, the third motor 223 drives the sector gear 222 to rotate. At this time, the fourth cylinder 23 drives the bonding plate 311 to move in the radial direction along the fixed wheel 4 to cover the cut part of the sealing strip and heat and bond it. After bonding is completed, the fourth cylinder resets. When the fixed plate rotates to the second winding position, the first cylinder 31 resets and the bonded sealing ring is taken out.

[0044] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
