Description

Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, specifically to a cutting device for sealing ring processing. Background Technology

[0002] A sealing ring is a mechanical component used to prevent fluid and liquid leakage. It is widely used in the automotive, aerospace, petrochemical, medical equipment, and home appliance lighting industries. Common sealing rings fill the gaps in the contact surface through elastic deformation, thereby forming a sealing barrier. In the mass production of sealing rings, large rolls of sealing rubber sheets are placed on a feeding system, and then the material is collected after passing through a cutting mechanism, a positioning mechanism, and a waste collection system.

[0003] According to Chinese Patent Publication No. CN222755572U, entitled "A Cutting Device for Processing Sealing Rings," the device mainly includes a base with a cutting frame mounted on its upper end; a lifting mechanism mounted on the cutting frame for lifting and lowering cutting scissors one and two; a connecting mechanism mounted at the lower end of the lifting mechanism for mounting cutting scissors one and two; a separating mechanism one mounted at the lower end of the connecting mechanism for separating the cut sealing ring from cutting scissors one and two; and a separating mechanism two mounted at the lower end of the connecting mechanism for separating the raw material inside cutting scissors one from cutting scissors one.

[0004] The aforementioned patent uses a connecting mechanism to install cutting shears one and two onto the lower end of a lifting mechanism. The raw material is then placed on the base. Next, the lifting mechanism pushes cutting shears one and two downwards to cut the raw material. Subsequently, separation mechanisms one and two separate the cut sealing ring and excess material from the cutting tools. This allows for a one-time cutting of the sealing ring without manual intervention, effectively improving processing efficiency and better meeting user needs. This utility model has a reasonable structure, enabling one-time cutting and convenient separation of material from the cutting tools, eliminating the need for manual operation and effectively improving processing efficiency to better meet user requirements.

[0005] However, during the batch cutting of rubber sealing rings, if the tension of the waste material take-up roller and the feeding roller is not properly matched, the cut waste material will accumulate below the cutting mechanism, thus preventing the cut sealing rings from falling normally into the collection device. This problem is more obvious during high-speed cutting, which hinders the batch cutting process and affects the processing efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a cutting device for processing sealing rings, thereby reducing the accumulation of waste material below the cutting mechanism that affects the normal collection of sealing rings and reduces processing efficiency.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a cutting device for processing sealing rings, including a base plate, a top plate, an unwinding roller, and a winding roller. A bracket is fixedly connected between the base plate and the top plate. Two support plates are fixedly connected to both sides of the bottom end of the top plate. A first motor is fixedly connected to one side of one of the support plates. A first rotating rod is fixedly connected to the output end of the first motor. A rotating plate is fixedly connected to the first rotating rod. A second motor is fixedly connected to the end of the rotating plate near the first motor. A rotating frame is fixedly connected to the output end of the second motor. A water pump is fixedly connected to the bottom end of one of the rotating frames. An annular pipe is fixedly connected to the output end of the water pump. Atomizing nozzles are uniformly fixedly connected to the side of the annular pipe away from the water pump. An electric push rod is fixedly connected to the bottom end of the other rotating frame. A connecting plate is fixedly connected to the output end of the push rod, and an annular cutter is fixedly connected to the bottom end of the connecting plate. A first groove is penetrating the base plate. A third motor is fixedly connected to one side of the base plate located in the first groove. A second rotating rod is fixedly connected to the output end of the third motor. A receiving plate is fixedly connected to the second rotating rod. Electric telescopic rods are fixedly connected to both sides of the first groove. A locking block is fixedly connected to the output end of the electric telescopic rod. The two locking blocks have a locking groove on their opposite sides, and the locking groove is located on the receiving plate. Two vertical plates are fixedly connected to both sides of the upper end of the base plate. A limiting groove is opened on the vertical plate, and a spring rod is fixedly connected in the limiting groove. A slider is sleeved on the bottom side of the spring rod. A pressure roller is fixedly connected between the two opposite sliders. Guide plates are fixedly connected to the two brackets.

[0008] As a preferred technical solution of this utility model, a folding cover is provided on the outside of the electric telescopic rod. The two ends of the folding cover are respectively fixedly connected to the opposite side of the first groove and the locking block. By providing the folding cover, it is possible to prevent cutting debris from contacting the electric telescopic rod.

[0009] As a preferred technical solution of this utility model, the card block is fixedly connected to a limiting rod on the side away from the receiving plate, and one end of the limiting rod is movably inserted into the base plate. By setting the limiting rod, the contact between the inner wall of the folding cover and the output end of the electric telescopic rod is reduced when the folding cover is retracted.

[0010] As a preferred technical solution of this utility model, a partition is fixedly connected to the side of the rotating plate away from the second motor. Hydraulic push rods are fixedly connected to both the upper and lower sides of the partition. A top block is fixedly connected to the output end of the hydraulic push rod. One end of the top block is inserted into the rotating frame. By setting the hydraulic push rod and the top block, the rotating frame can be limited, and the stability of the rotating frame after it stops can be improved.

[0011] As a preferred technical solution of this utility model, two air pumps are provided in the other rotating frame. One air pump is connected to the innermost annular cutter, and the other air pump is in contact with the gap between the two annular cutters. When a single cut is completed, airflow can be drawn into the inner annular cutter by the left air pump. By pressurizing, the waste material in the gap between the inner annular cutters falls off. Then, the first motor drives the rotating plate to rotate, and the second motor drives the rotating frame to rotate, so that the gap between the two annular cutters corresponds to the other air pump, thereby causing the cut sealing ring to disengage.

[0012] This utility model has the following advantages: The electric push rod inside the rotating frame extends to move the moving plate until it contacts and cuts the rubber sheet on the receiving plate, thereby achieving the effect of cutting the sealing ring.

[0013] By setting two independently rotatable frames, when a single cut is completed, the two frames can be rotated until the atomizing nozzle aligns with the inner cavity of the annular cutter. The annular cutter is lubricated and cooled by the water pump. At the same time, two air pumps are set up to separate the waste material from the sealing ring. Then the receiving plate flips over, which can further guide the waste material, thereby reducing the waste material stuck on the bottom side of the cutting mechanism and improving processing efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3The cutting device for processing sealing rings includes a base plate 1, a top plate 2, an unwinding roller, and a winding roller. A bracket is fixedly connected between the base plate 1 and the top plate 2. Two support plates 3 are fixedly connected to both sides of the bottom end of the top plate 2. A first motor is fixedly connected to one side of one of the support plates 3. The first motor can drive a first rotating rod 4 to rotate, which can cause a rotating plate 5 to rotate. The output end of the first motor is fixedly connected to the first rotating rod 4. The rotating plate 5 is fixedly connected to the first rotating rod 4. A second motor is fixedly connected to the end of the rotating plate 5 near the first motor. The second motor drives a rotating frame 6 to rotate, which can change whether the atomizing nozzle and the annular cutter 11 are aligned. The output end of the second motor is fixedly connected to the rotating frame 6. The bottom end of one of the rotating frames 6 is fixed. A water pump 7 is connected, with its input end connected to an external lubricant via a hose. An annular fitting 8 is fixedly connected to the output end of the water pump 7. Atomizing nozzles are uniformly fixedly connected to the side of the annular fitting 8 away from the water pump 7. An electric push rod 9 is fixedly connected to the bottom end of another rotating frame 6. The extension of the electric push rod 9 allows the connecting plate 10 to move. When the connecting plate 10 is parallel to the receiving plate 14 and the annular cutter 11 corresponds to the receiving plate 14, the extension of the electric push rod 9 provides cutting. The output end of the electric push rod 9 is fixedly connected to the connecting plate 10, and the bottom end of the connecting plate 10 is fixedly connected to the annular cutter 11. The annular cutter 11 is double-ringed, and the annular gap formed by the two annular cutters 11 constitutes the cutting width of the sealing ring. The bottom plate 1... A first groove 12 runs through the top. A third motor is fixedly connected to one side of the base plate 1, which drives the second rotating rod 13 to rotate, causing the receiving plate 14 to flip. This allows the waste material inside the inner annular cutter 11 to detach when the receiving plate 14 rotates to an inclined position. The output end of the third motor is fixedly connected to the second rotating rod 13, and the receiving plate 14 is fixedly connected to the second rotating rod 13. Electric telescopic rods 15 are fixedly connected to both sides of the first groove 12. When the electric telescopic rods 15 extend, the locking block 16 engages with the locking slot 17, thereby improving the stability of the receiving plate 14 during the cutting process. The output end of the electric telescopic rod 15 is fixedly connected to a locking... Block 16, two blocks 16 have a slot 17 on one side of their opposite sides, and the slot 17 is located on the receiving plate 14. Two vertical plates 18 are fixedly connected to both sides of the upper end of the base plate 1. The vertical plates 18 have limit grooves and spring rods 19 are fixedly connected in the limit grooves. The spring rods 19 cooperate with the sliders 20 and the rotatable pressure rollers 21, and the weight of the rubber plate also helps to stabilize the cutting. The sliders 20 are sleeved on the bottom side of the spring rods 19. The pressure rollers 21 are fixedly connected between the two opposing sliders 20. Guide plates 28 are fixedly connected to the two brackets. When the first rotating rod 4 drives the rotating plate 5 to rotate to an inclined position, the electric push rod 9 extends so that the annular cutter 11 is located on the upper side of the guide plate 28. Figure 1 The air pump 27 on the right side is inflated by the external environment, which increases the pressure between the two annular cutters 11, causing the formed sealing ring to fall onto the guide plate 28.

[0018] The electric telescopic rod 15 is provided with a folding cover 22 on its outer side. The two ends of the folding cover 22 are respectively fixedly connected to the opposite side of the first groove 12 and the locking block 16. By providing the folding cover 22, the contact between the cutting debris and the output end of the electric telescopic rod 15 is reduced.

[0019] Among them, the card block 16 is fixedly connected to the side away from the receiving plate 14 with a limit rod 23. One end of the limit rod 23 is movably inserted into the base plate 1. By setting the limit rod 23, the contact between the folding cover 22 and the electric telescopic rod 15 can be prevented.

[0020] One of the rotating plates 5 is fixedly connected to a partition 24 on the side away from the second motor. Hydraulic push rods 25 are fixedly connected to both the upper and lower sides of the partition 24. A top block 26 is fixedly connected to the output end of the hydraulic push rod 25. One end of the top block 26 is inserted into the rotating frame 6. By setting the hydraulic push rod 25 to extend so that the top block 26 contacts the rotating frame 6, the top block 26 can be stopped when the rotating frame 6 rotates to be perpendicular to the top block 26, thus stabilizing the rotating frame 6.

[0021] Two air pumps 27 are installed in another rotating frame 6. One air pump 27 is connected to the innermost annular cutter 11, and the other air pump 27 is in contact with the gap between the two annular cutters 11. The air pumps 27 are installed to assist in unloading.

[0022] Working principle: The take-up roller winds up the waste material, and the unwind roller releases the material, causing part of the sealing rubber sheet to extend on the upper side of the receiving plate 14. The spring rod 19, slider 20, and pressure roller 21 press down on the extended sealing rubber sheet. During a single cut, the first motor drives the first rotating rod 4 to rotate until the annular cutter 11 is perpendicular to the sealing rubber sheet. Then, the electric push rod 9 extends, causing the connecting plate 10 and the annular cutter 11 to press down and cut the rubber sealing ring. Figure 1 The left-side air pump 27 draws air, pressurizing the gap between the inner annular cutter 11 and the sealing rubber plate. This causes the waste material from the inner annular cutter 11 to detach and remain on the receiving plate 14. The first motor then controls the first rotating rod 4 to rotate, causing the annular cutter 11 to tilt relative to the guide plate 28. Then, the electric push rod 9 extends, positioning the annular cutter 11 above the guide plate 28. Figure 1 The air pump 27 on the right side is inflated, which increases the pressure in the gap between the two annular cutters 11, causing the rubber sealing ring to detach and fall onto the guide plate 28 for collection. Further rotation of the first and second motors enables the atomizing nozzles in the two rotating frames 6 to align with the annular cutters 11. At this time, the water pump 7 draws water through the annular pipe 8 and the atomizing nozzles, and lubricates the annular cutters 11, thereby reducing cutting friction.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] 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.
