[0002] A sealing ring is an annular component used to prevent liquid or gas leakage. It is usually made of rubber, plastic or other elastic materials. It is widely used in machinery, automobile, aviation and other industries to ensure the sealing between connected parts, reduce friction and wear, and improve the operating efficiency and reliability of equipment.

[0003] There are several production processes for sealing rings. One of them is to form multiple sealing rings of specified sizes by circumferential cutting of the rubber tube sealing profile. Therefore, a circumferential cutting device for the sealing ring is required for the production of such sealing rings. When the circumferential cutting device for the sealing ring is used, the rubber tube sealing profile needs to be sleeved on the sleeve roller. Since the inner wall diameter of the rubber tube sealing profile is equivalent to the diameter of the sleeve roller, the staff usually sleeves the rubber tube on the rotating sleeve roller. The rotating sleeve roller can facilitate the sleeve of the rubber tube. However, during the sleeve process of the rubber tube, the rubber tube will twist, causing the rubber tube to deform, the circumferential cutting size cannot be accurate, and the operational risk factor of the rubber tube during the sleeve process is increased.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] See also Figures 1 to 12 In an embodiment of the utility model, a circumferential cutting device for a sealing ring includes a frame 1 and a base 2 arranged on the frame 1, characterized in that a sleeve roller 3 is rotatably provided on one side of the base 2, a motor is integrated and installed inside the frame 1, and one end of the sleeve roller 3 extending into the base 2 is coaxially connected to the output end of the motor;

[0044] Two sets of tool mechanisms are symmetrically arranged on the frame 1. The two sets of tool mechanisms are arranged on both sides of the sleeve roller 3, and the base 2 is located at one end of the tool mechanism. The tool mechanism cooperates with the sleeve roller 3 to circumferentially cut the sealing profile elastically fastened and enveloping on the sleeve roller 3.

[0045] The frame 1 is also provided with an auxiliary enveloping mechanism, which is located between the two sets of tool mechanisms. The auxiliary enveloping mechanism is used to elastically expand the sealing profile to be cut and sleeve it on the sleeve roller 3.

[0046] In this embodiment, the sealing profile can be elastically expanded by the auxiliary enveloping mechanism, so that the expanded sealing profile is sleeved on the sleeve roller 3, and the sleeve roller 3 is rotated by the motor driven by the motor integrated inside the base 2, so that the sealing profile elastically and tightly enveloping the sleeve roller 3 is circumferentially cut by the two groups of tool mechanisms symmetrically arranged on the frame 1 and arranged on both sides of the sleeve roller 3, thereby improving the convenience of sleeved on the sleeve roller 3. Compared with the manual sleeved sealing profile on the rotating sleeve roller 3 in the prior art, the sleeved sealing profile of this technical solution is safer and more convenient to operate.

[0047] As a further solution of the present invention, the tool mechanism includes a first slide rail 6 provided on the frame 1, a first sliding seat 7 slidably provided on the first slide rail 6, a tool holder 9 having one end rotatably engaged with the first sliding seat 7, a blade 11 detachably provided on the tool holder 9, and an adjustment mechanism connecting the tool holder 9 and the first sliding seat 7;

[0048] The adjusting mechanism is used to drive the tool holder 9 to rotate around one end thereof relative to the first sliding seat 7 so that the blade 11 fixed on the tool holder 9 moves closer to or away from the sleeve roller 3 .

[0049] In this embodiment, the first sliding seat 7 can be slidably adjusted on the first slide rail 6, so that the tool holder 9 can move parallel to the sleeve roller 3, thereby realizing uniform circumferential cutting operation on the sealing profile sleeved on the sleeve roller 3. The blade 11 on the tool holder 9 can be disassembled and replaced. When the cutting edge of the blade 11 becomes blunt and needs to be polished, it can be disassembled and polished for use. Through the adjustment mechanism, the tool holder 9 can be rotated and adjusted around one end on the first sliding seat 7, so that the blade 11 can be moved closer to or farther away from the sleeve roller 3, thereby realizing circumferential cutting of the sealing profile.

[0050] As a further solution of the present invention, the auxiliary enveloping mechanism includes a plurality of circumferentially distributed support rods 16, and the circumferential cylinder formed by the plurality of support rods 16 is concentric with the sleeve roller 3;

[0051] The support rod 16 cooperates with the rotating seat 14, and the rotating seat 14 is rotatably arranged in the second sliding seat 13. The second sliding seat 13 is slidably matched with the second slide rail 12 provided on the frame 1;

[0052] The second sliding seat 13 is further provided with a contraction and expansion mechanism for cooperating with the support rods 16 and the rotating seat 14. When the rotating seat 14 rotates, the contraction and expansion mechanism drives the multiple support rods 16 to contract or expand synchronously.

[0053] In this embodiment, the rotating seat 14 rotates on the second sliding seat 13. When the sealing profile is sleeved on the circumferential cylinder formed by multiple struts 16, the rotating seat 14 is rotated and adjusted to allow the multiple struts 16 to contract or extend synchronously. When the multiple struts 16 are extended, the elastic sealing profile can be expanded, allowing the sealing profile to be conveniently sleeved on the sleeve roller 3.

[0054] As a further solution of the present invention, the expansion and contraction mechanism includes a fixed seat 15 disposed in the second sliding seat 13, and a plurality of sliding grooves 18 are formed on the fixed seat 15 along its radial direction, and the plurality of sliding grooves 18 are distributed along the circumference;

[0055] The support rod 16 passes through the sliding groove 18 and slides with it. A plurality of arcuate grooves 17 are formed on one side of the rotating seat 14, and the plurality of arcuate grooves 17 are also distributed along the circumference. One end of the support rod 16 is integrally formed with a limiting convex edge 19, which slides into the arcuate groove 17.

[0056] A mounting cover is fixedly mounted on a side of the second sliding seat 13 facing away from the base 2 , and an auxiliary motor is mounted on the mounting cover. The output shaft of the auxiliary motor is coaxially fixed to the rotating seat 14 .

[0057] In this embodiment, the sliding groove 18 provided on the fixed seat 15 is slidably engaged with the multiple struts 16. When the rotating seat 14 is rotated and adjusted to cause the multiple struts 16 to contract or extend, the two limiting ridges 19 provided on the struts 16 respectively abut against one side of the rotating seat 14 and the fixed seat 15 away from the side, thereby enabling the multiple struts 16 to contract and extend synchronously, meeting the requirements for the expansion and contraction of the sealing profile.

[0058] As a further solution of the present invention, the adjustment mechanism includes a second electric push rod 8 provided on the first sliding seat 7, a sliding frame provided at one end of the piston rod of the second electric push rod 8, and a movable groove 10 provided on the side of the tool holder 9 facing away from the blade 11 and slidably connected to the sliding shaft on the sliding frame;

[0059] The piston rod of the second electric push rod 8 is telescopically adjusted to control the sliding shaft on the sliding frame to slide in the movable groove 10 .

[0060] In this embodiment, the adjustment mechanism can be used to adjust the inclination angle of the tool holder 9 on the first sliding seat 7. Through the telescopic adjustment of the piston rod of the second electric push rod 8, the sliding shaft on the sliding frame at one end of the piston rod is slid and adjusted inside the movable groove 10. When the tool holder 9 is tilted, the sliding shaft on the sliding frame will slide at the contact position in the movable groove 10. Therefore, when the second electric push rod 8 is fixedly installed on the first sliding seat 7, it does not affect the telescopic adjustment of the piston rod, so that the tool holder 9 rotates around one end of it on the first sliding seat 7, meeting the adjustment requirements.

[0061] As a further solution of the present invention, a first push plate 4 is slidably sleeved on the sleeve roller 3, and bumps are integrally formed on the upper and lower sides of the first push plate 4. The two bumps are respectively fixedly connected to the piston rod ends of the two first electric push rods 5. The two first electric push rods 5 are arranged in the cavity of the base 2 on both sides of the motor integrated inside the base 2;

[0062] The piston rods of the two first electric push rods 5 are telescopically adjusted to allow the first push plate 4 to slide on the sleeve roller 3, thereby pushing down the cut sealing profile sleeved on the sleeve roller 3 to complete the unloading.

[0063] In this embodiment, after the circumferential cutting of the sealing profile sleeved on the sleeve roller 3 is completed, since the sealing profile is tightly wrapped around the sleeve roller 3, the piston rod of the first electric push rod 5 is extended, so that the first push plate 4 can be slid and adjusted on the sleeve roller 3. Since the center part of the first push plate 4 is in sliding contact with the sleeve roller 3, when the first push plate 4 is slid and adjusted, the circumferentially cut sealing profile sleeved on the sleeve roller 3 can be pushed down, thereby realizing the pushing and unloading operation of the sealing ring formed by the cutting.

[0064] As a further solution of the present invention, a screw rod parallel to the first slide rail 6 is rotatably connected thereto, a servo motor is provided on the first slide rail 6 at one end of the screw rod away from the base 2, and the output shaft of the servo motor is coaxially fixed to one end of the screw rod;

[0065] The screw rod is slidably connected to the first sliding seat 7 and is threadedly connected in the sliding groove of the first slide rail 6. The operation of the servo motor drives the screw rod to rotate on the first slide rail 6, so that the first sliding seat 7 threadedly connected to the screw rod moves closer to or away from one end of the base 2.

[0066] In this embodiment, the servo motor on the first slide rail 6 drives the screw to rotate, so that the first sliding seat 7 threadedly connected to the screw can slide and adjust on the first slide rail 6, controlling the first sliding seat 7 to move closer to or away from one end of the base 2 on the first slide rail 6, thereby meeting the adjustment requirements for the equally spaced circumferential cutting of the sealing profile.

[0067] As a further solution of the present invention, another screw rod parallel to the second slide rail 12 is rotatably connected thereto, and another servo motor is provided on the second slide rail 12 at one end of the screw rod away from the base 2, and the output shaft of the servo motor is coaxially fixed to one end of the screw rod;

[0068] The screw and the second sliding seat 13 are slidably connected to the position in the slide groove of the second slide rail 12 and are threadedly connected. The operation of the servo motor drives the screw to rotate on the second slide rail 12, so that the second sliding seat 13 threadedly connected to the screw moves closer to or away from one end of the base 2.

[0069] In this embodiment, the operation of the servo motor on the second slide rail 12 causes the screw to rotate, and the screw causes the second sliding seat 13 threadedly connected to it and slidingly connected to the second slide rail 12 to slide and adjust, and can control the second sliding seat 13 on the second slide rail 12 to move closer to or away from one end of the base 2, so that the sealing profile can be more convenient when loading and sleeved, meeting the sleeve use requirements.

[0070] As a further solution of the present invention, two third electric push rods 21 are respectively provided on both sides of the mounting cover of the second sliding seat 13, and one end of the piston rod of the two third electric push rods 21 is respectively fixedly connected to the bosses integrally formed on both sides of the second push plate 20;

[0071] The third electric push rod 21 is provided with slots that are the same as the arc-shaped slots 17 on the rotating seat 14. The slots are also distributed along the circumference. The slots are correspondingly connected to the multiple support rods 16 for sliding. The piston rod telescopic adjustment control of the third electric push rod 21 allows the second push plate 20 to slide on the multiple support rods 16, thereby allowing the sealing profiles elastically expanded on the multiple support rods 16 to push the material out.

[0072] In this embodiment, when the sealing profile sleeved on the support rod 16 needs to be removed for unloading, the piston rod of the third electric push rod 21 is extended, so that the second push plate 20 slides on the support rod 16, thereby enabling the sealing profile sleeved on the support rod 16 to be pushed off, so that the sealing profile can be unloaded. When the sealing profile is pushed for unloading, the second sliding seat 13 resets and slides to ensure that the sealing profile on the support rod 16 can complete the unloading operation.

[0073] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
