Description

Technical Field

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

[0002] The extruded rubber strip of the sealing ring is continuous, while the sealing rings used in actual applications have certain length or specific size requirements. For example, when producing a large number of O-rings for small electronic devices, the extruded rubber strip may be quite long and needs to be cut according to the standard length of the sealing ring to divide it into individual sealing ring prototypes.

[0003] Cutting devices used in the production of sealing rings play a crucial role in several aspects. In terms of dimensional control, they can precisely cut sealing ring rubber strips to the set length. For example, in automotive engine sealing rings, the length error can be controlled to a minimum, ensuring compliance with high design standards. Regarding shape specifications, for irregularly shaped sealing rings, they can be cut into preliminary shapes using relevant molds and tools, facilitating subsequent processes and adaptability, greatly improving production efficiency. Compared to manual cutting, it can operate quickly and continuously. In automated production lines, it can automatically adjust the cutting frequency according to speed, processing large quantities of rubber strips in a short time to meet the needs of large-scale production, playing a key role in driving the entire sealing ring production process.

[0004] Chinese patent CN216068774U discloses a rubber strip cutting device for producing sealing ring blanks. The device includes a bracket, a traction driven wheel, a traction driving wheel, a driving wheel motor, a pressure wheel assembly, a cutter assembly, a cutter motor, a servo manipulator assembly for pulling the rubber strip, and a vertical mounting plate, a cutting support platform, and a rubber strip support platform sequentially mounted on the bracket in the rubber strip feeding direction. The pressure wheel assembly is located above the traction driving wheel, which is connected to the driving wheel motor. The cutter assembly includes a cutter and a mounting sleeve. The cutter is radially mounted on the outer side of the mounting sleeve and connected to the cutter motor via the mounting sleeve. The cutting support platform consists of two separate support blocks with a gap between them for the cutter to pass through. This device can accurately control the cutting length of the rubber strip, meeting the high precision requirements for the length of the cut short rubber strip in the production process. It is also easy to operate and has high work efficiency.

[0005] Existing cutting devices for sealing ring production can generally only clamp and cut single sealing ring rubber strips, and are not easy to feed quickly, which greatly limits the flexibility and diversity of production. They cannot meet the needs of producing sealing rings of various specifications at the same time. If it is necessary to switch to producing sealing rings of different sizes or materials, a lot of time must be spent adjusting or replacing the device, which reduces production efficiency. The difficulty in feeding quickly leads to frequent interruptions in the production process. The device is in a standby state for a long time waiting for feeding, which not only reduces the output per unit time, but also causes energy waste. Moreover, slow feeding can cause the rubber strips to accumulate or twist at the feed port, affecting the cutting accuracy and quality, and increasing the defect rate. Utility Model Content

[0029] Please see Figures 1-6A cutting device for producing sealing rings includes a housing 1, with three clamping rollers 2 arranged inside the housing 1. Two of the clamping rollers 2 have adjusting components 4 at their ends. A pushing component is arranged inside the three clamping rollers 2, with a motor 3 at one end of the pushing component. A cylinder 5 is fixed to the top of the housing 1 via a connecting component, and a cutting component 7 is arranged at the bottom of the cylinder 5. The adjusting components 4 are configured to adjust the distance between the three clamping rollers 2. The pushing component 6 is configured to cooperate with the motor 3 to feed the cutting component 7. The cutting component 7... The adjustment assembly 4, which is assembled to cooperate with the cylinder 5 for cutting, includes two telescopic rods 41. Both telescopic rods 41 are fixed to the top of the bottom wall of the housing 1. The output ends of the two telescopic rods 41 are fixed with lifting plates 42. The top of the bottom wall of the housing 1 is fixed with two inclined plates 43. One side of the two inclined plates 43 is provided with inclined holes 45. The inner side of the two inclined holes 45 is slidably engaged with connecting blocks 44, and the two connecting blocks 44 are slidably engaged with the inner side of the lifting plate 42. One end of each of the two clamping rods 2 is fixed to the bottom of the two connecting blocks 44.

[0030] In this embodiment, the output ends of the two telescopic rods 41 extend, and the output ends of the two telescopic rods 41 drive the lifting plate 42 to move the two connecting blocks 44 to the side closer to the top of the chassis 1. At the same time, the two connecting blocks 44 move to the side further away from each other under the restriction of the two inclined grooves, thereby increasing the distance between the three clamping rods 2.

[0031] The output ends of the two telescopic rods 41 retract, and the output ends of the two telescopic rods 41 drive the lifting plate 42 to move the two connecting blocks 44 to the side closer to the bottom of the chassis 1. At the same time, the two connecting blocks 44 move to the side closer to each other under the restriction of the two inclined grooves, thereby reducing the distance between the three clamping rods 2.

[0032] According to the actual situation, the staff can adjust the distance between the three clamping rods 2 by controlling the telescopic rod 41 so that the inner side of the three clamping rods 2 is aligned with the outer side of the sealing ring rubber strip, and then insert the sealing ring rubber strip between the three clamping rods 2.

[0033] Furthermore, the motor 3 is fixed to the top of the bottom wall of the housing 1, and the motor 3 is located on the side of the two telescopic rods 41 away from the clamping rods 2. The other clamping rod 2 is fixed to the top of the bottom wall of the housing 1, and the other clamping rod 2 is located at the bottom of the two clamping rods 2. The pusher 6 includes a threaded rod 61, which is rotatably connected to the top of the bottom wall of the housing 1 through a connecting component. One end of the threaded rod 61 is fixedly connected to the output end of the motor 3. A round rod is fixedly connected to the top of the bottom wall of the housing 1 through a connecting component. The round rod, the threaded rod 61 and the other clamping rod 2 are located on the same horizontal plane. The other clamping rod 2 is located on the side of the round rod and the threaded rod 61 that are close to each other. A meshing plate 64 is threadedly installed on the outer side of the threaded rod 61. A limit plate 63 is slidably connected to the outer side of the round rod. A push plate 65 is slidably engaged on the inner side of the meshing plate 64.

[0034] In this embodiment, the operator controls the motor 3 to rotate forward. The output end of the motor 3 drives the threaded rod 61 to rotate forward. The threaded rod 61 drives the meshing plate 64 to move towards the side closer to the cutter 71 through the meshing action. The limiting plate 63 prevents the meshing plate 64 and the push plate 65 from shaking during the movement under the action of the square rod. The meshing plate 64 drives the push plate 65 to move towards the side closer to the cutter 71. The push plate 65 pushes the sealing ring rubber strip to move towards the side closer to the cutter 71, thus completing the feeding.

[0035] Furthermore, a spring is fixed to the side of the limiting plate 63 away from the clamping rod 2, and a pressure plate 66 is fixed to the other end of the spring. The pressure plate 66 is configured with two sections: a round rod section and a flat rod section. The push plate 65 is located on the outside of the round rod section, and the round rod section is located on the inside of the limiting plate 63.

[0036] In this embodiment, the worker presses the pressure plate 66 with his hand, and the pressure plate 66 squeezes the spring and moves to the side closer to the clamping rod 2. The round rod end of the pressure plate 66 moves out from the inside of the push plate 65, and the flat rod section moves into the inside of the push plate 65, releasing the restriction on the push rod. Then, the worker uses his other hand to drive the push plate 65 to the side away from the limiting plate 63, releasing the enclosure of the three clamping rods 2, which is convenient for loading materials.

[0037] The worker manually moves one end of the push plate 65 back to the inside of the limiting plate 63, releases the pressure plate 66, and the round rod section of the pressure plate 66 moves back into the inside of the push plate 65, connecting the limiting plate 63 and the meshing plate 64 together again, so as to facilitate the feeding of material from the pusher 6 to the cutter 7.

[0038] Furthermore, the cutting component 7 includes a cutter 71, which is fixedly connected to the bottom of the output end of the cylinder 5. Limiting plates 72 are fixed on both sides of the cutter 71. Two limiting rods 73 are fixed on the top of the bottom wall of the housing 1. The two limiting rods 73 are located on the side of the clamping rod 2 away from the motor 3. The two limiting plates 72 are slidably connected to the outside of the two limiting rods 73. Two springs are fixed on the top of the bottom wall of the housing 1. Rubber pads 74 are fixed on the top of the two springs. The rubber pads 74 are slidably connected to the outside of the two limiting rods 73 and are located at the bottom of the limiting plates 72.

[0039] In this embodiment, the spring 2 and the rubber pad 74 can prevent the cutter 71 from hitting the housing 1 and the pusher 6. When the sealing ring rubber strip moves out of the length of the three clamping rods 2 to the cutting length, the control motor 3 stops rotating and the cylinder 5 is started. The cylinder 5 drives the cutter 71 to move to the side closer to the bottom of the housing 1, thereby cutting off the sealing ring rubber strip.

[0040] Working principle: Before using the device, check for any issues that might affect its use. The operator presses down on the pressure plate 66, causing the round rod end of the pressure plate 66 to move out from the inside of the push plate 65, while the flat rod section moves in, releasing the restriction on the push rod. Then, the operator uses their other hand to move the push plate 65 away from the limiting plate 63, releasing the seal on the three clamping rollers 2. Next, adjust the distance between the three clamping rollers 2 using the telescopic rod 41, aligning the inner sides of the three clamping rollers 2 with the outer sides of the sealing ring rubber strip. Then, insert the sealing ring rubber strip between the three clamping rollers 2. Finally, the operator manually... One end of the push plate 65 moves back to the inside of the limiting plate 63, releasing the pressure plate 66. The round rod section of the pressure plate 66 moves back into the inside of the push plate 65, connecting the limiting plate 63 and the meshing plate 64 together again. The operator controls the motor 3 to rotate forward, and the push plate 65 pushes the sealing ring rubber strip to the side closer to the cutter 71. When the sealing ring rubber strip moves out of the length of three clamping rollers 2 and reaches the cutting length, the operator controls the motor 3 to stop rotating and starts the cylinder 5. The cylinder 5 drives the cutter 71 to the side closer to the bottom of the machine box 1, thereby cutting off the sealing ring rubber strip. Then, the same steps are used to cut the sealing ring rubber strip into sealing rings of the required length.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
