DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: Figure 1-Figure 7 As shown, an automatic cutting and trimming device for a rubber sealing ring includes a support plate 100 , a fixing mechanism 200 , a driving mechanism 300 , a pushing mechanism 400 and a cutting and trimming mechanism 500 .

[0024] A vertical plate 102 is installed on the top surface of the support plate 100, and a fixing member 103 is installed on the vertical plate 102; the fixing mechanism 200 is used to fix the rubber column 600; the driving mechanism 300 is used to drive the rubber column 600 installed on the fixing mechanism 200 to rotate; the cutting and trimming mechanism 500 is installed on the vertical plate 102, and the cutting and trimming mechanism 500 is used to cut and trim the rubber column 600.

[0025] Specifically, the carrier plate 100 serves as a basic supporting component and provides an installation position for other components. The vertical plate 102 is installed on the carrier plate 100 to provide an installation space for the fixing part 103 and the cutting and trimming mechanism 500. The fixing mechanism 200 is responsible for stabilizing the rubber column 600 to ensure that the rubber column 600 will not be displaced or shaken during subsequent processing. The driving mechanism 300 provides power to rotate the rubber column 600 to meet the requirements of processing the rubber column 600 at different angles during cutting and trimming.

[0026] When the driving mechanism 300 is running, it will drive the rubber column 600 to rotate through the fixing mechanism 200, and push the fixing mechanism 200 and the rubber column 600 to move horizontally intermittently through the pushing mechanism 400, so that the cutting and trimming mechanism 500 completes the trimming of the entire rubber column 600, and cuts the trimmed rubber column 600, thereby cutting the rubber column 600 into several rubber sealing rings, thereby improving production efficiency.

[0027] like Figure 4 and Figure 5 As shown, the fixing mechanism 200 includes a moving plate 201 , a connecting member 205 , a first cylinder 206 , a second cylinder 207 , a plurality of inner support assemblies 210 and an adjusting assembly 220 .

[0028] The movable plate 201 is slidably connected to the supporting plate 100; the first cylinder 206 is fixedly mounted on the connecting piece 205; a plurality of inner support assemblies 210 are equidistantly installed on the first cylinder 206 and the second cylinder 207, and the inner support assemblies 210 are used to be inserted into the rubber column 600 and support the rubber column 600; the adjusting assembly 220 is used to adjust the distance between the first cylinder 206 and the second cylinder 207 so that the inner support assemblies 210 are in contact with or separated from the rubber column 600.

[0029] The inner support assembly 210 includes an arc-shaped plate 211 and two hinged rods 212. One end of the two hinged rods 212 is hinged to the arc-shaped plate 211, and the other ends of the two hinged rods 212 are hinged to the first cylinder 206 and the second cylinder 207 respectively.

[0030] Specifically, the rubber column 600 is first put on the inner support component 210, and then the distance between the second cylinder 207 and the first cylinder 206 is adjusted by the adjustment component 220, so that the two hinged rods 212 push the arc plate 211 to move, so that the arc plate 211 abuts against the inner wall of the rubber column 600, so that multiple arc plates 211 stably support the rubber column 600.

[0031] The movable plate 201 is slidably connected to the supporting plate 100, so that the fixing mechanism 200 as a whole can move in the horizontal direction, providing a basis for the subsequent pushing mechanism 400 to push it to move; the connecting member 205 plays a role of connection and transmission, transmitting the power of the driving mechanism 300 to the first cylinder 206, and the first cylinder 206 is fixedly mounted on the connecting member 205 and rotates with the connecting member 205; if at this time, the rubber column 600 is fixed to the first cylinder 206 and the second cylinder 207 by the inner support assembly 210, then the rotation of the first cylinder 206 will also drive the rubber column 600 to rotate.

[0032] like Figure 5 As shown, the connecting member 205 includes a fixing column 2051, a first square groove 2052, a first fixing ring 2053, a thread groove 2054 and a first bevel gear 2055. The first square groove 2052 is provided on the fixing column 2051; the first fixing ring 2053 is fixedly sleeved on the fixing column 2051, and the first fixing ring 2053 is fixedly connected to the first cylinder 206; the thread groove 2054 is provided on the fixing column 2051; and the first bevel gear 2055 is fixedly sleeved on the fixing column 2051.

[0033] Specifically, the fixed column 2051 is the main part of the connecting member 205, providing a mounting base for other components. The first square groove 2052 is plugged and matched with the square plug rod 303 in the driving mechanism 300 to realize the transmission of power, so that the connecting member 205 can drive the first cylinder 206 to rotate. The first fixed ring 2053 is fixedly sleeved on the fixed column 2051 to ensure that the first cylinder 206 and the fixed column 2051 rotate synchronously. The threaded groove 2054 is threadedly connected with the threaded rod 221 in the adjustment component 220, and the spacing between the first cylinder 206 and the second cylinder 207 is adjusted by rotating the threaded rod 221. The first bevel gear 2055 is used to cooperate with other bevel gears to realize the transmission and reversing of power, so that the power transmission of the device is more flexible, ensuring that the various components of the fixing mechanism 200 work together to achieve the fixation and rotation of the rubber column 600.

[0034] like Figure 6As shown, the pushing mechanism 400 includes a second mounting seat 401, a reducer 402, a second bevel gear 403, a disc 404, a round pin 405 and a locking arc plate 406. The second mounting seat 401 is mounted on the top surface of the moving plate 201; the reducer 402 is mounted on the second mounting seat 401; the second bevel gear 403 is mounted on the input shaft of the reducer 402; the disc 404 is mounted on the output shaft of the reducer 402; the round pin 405 is mounted on the disc 404; and the locking arc plate 406 is mounted on the disc 404.

[0035] The fixing member 103 includes a fixing strip 1031, a plurality of guide grooves 1032 and a plurality of arc-shaped grooves 1033. The fixing strip 1031 is mounted on the vertical plate 102; a plurality of guide grooves 1032 are equidistantly provided on the fixing strip 1031, and the guide grooves 1032 match the round pins 405; a plurality of arc-shaped grooves 1033 are equidistantly provided on the fixing strip 1031, and the plurality of arc-shaped grooves 1033 are staggered with the plurality of guide grooves 1032, and the arc-shaped grooves 1033 match the locking arc plate 406.

[0036] Specifically, the second mounting seat 401 provides a mounting position for the reducer 402. The reducer 402 is used to reduce the rotation speed of the disc 404, the round pin 405 and the locking arc plate 406.

[0037] The second bevel gear 403 is mounted on the input shaft of the reducer 402, and the second bevel gear 403 cooperates with the first bevel gear 2055 to realize the input of power. The disc 404 is mounted on the output shaft of the reducer 402 and rotates with the output shaft. The round pin 405 is mounted on the disc 404. During the rotation of the disc 404, the round pin 405 will intermittently cooperate with the guide groove 1032 on the fixing member 103 to push the movable plate 201 to move horizontally intermittently. When the disc 404 rotates, the locking arc plate 406 intermittently cooperates with the arc groove 1033 on the fixing member 103 to lock the position of the movable plate 201, ensure the stability and accuracy of the movable plate 201 during the movement, realize the intermittent horizontal movement of the fixing mechanism 200 and the rubber column 600, and cooperate with the cutting and trimming mechanism 500 to complete the processing.

[0038] When the driving mechanism 300 is running, it will drive the connecting member 205 to rotate, and then drive the first cylinder 206, the inner support assembly 210 and the rubber column 600 to rotate, so that the cutting and trimming mechanism 500 trims and cuts the rubber column 600.

[0039] And when the connecting member 205 rotates, it will also drive the input shaft of the reducer 402 to rotate through the second bevel gear 403, so that the output shaft of the reducer 402 drives the disc 404, the round pin 405 and the locking arc plate 406 to rotate, and the rotating round pin 405 cooperates with the guide groove 1032 on the fixed member 103 to push the movable plate 201 to move horizontally intermittently, thereby driving the first cylinder 206, the inner support machine assembly and the rubber column 600 to move horizontally intermittently, so that the cutting and trimming mechanism 500 trims and cuts other parts of the rubber column 600.

[0040] like Figure 4 As shown, the fixing mechanism 200 further includes a plurality of rollers 202 and a support plate 203. The plurality of rollers 202 are all mounted on the bottom surface of the moving plate 201, and the plurality of rollers 202 are respectively slidably connected to a plurality of slide grooves 101 provided on the top surface of the carrier plate 100; the support plate 203 is mounted on the top surface of the moving plate 201, and the support plate 203 is rotatably connected to the fixing column 2051.

[0041] Specifically, the plurality of rollers 202 are slidably connected to the slide grooves 101 on the top surface of the carrier plate 100, so that the movable plate 201 moves more smoothly during horizontal movement and reduces friction. The support plate 203 is rotatably connected to the fixed column 2051 to provide support for the fixed column 2051 and ensure the stability of the fixed column 2051 during rotation.

[0042] like Figure 4 As shown, the support assembly 204 includes a fixed plate 2041, a hinged plate 2042, two slots 2043, an I-shaped plug block 2044 and a handle 2045. The fixed plate 2041 is mounted on the top surface of the movable plate 201; the hinged plate 2042 is hinged to the fixed plate 2041, and a support groove is provided on the top surface of the hinged plate 2042; the two slots 2043 are respectively provided on the fixed plate 2041 and the hinged plate 2042; the I-shaped plug block 2044 is plugged into the two slots 2043; the handle 2045 is mounted on the I-shaped plug block 2044, and the handle 2045 is in the shape of a quadrangular prism.

[0043] The hinged plate 2042 is hinged to the fixed plate 2041 , and the support groove on the top surface of the hinged plate 2042 contacts the rotating ring 223 in the adjusting assembly 220 , thereby providing support for the rotating ring 223 .

[0044] Specifically, when the adjustment assembly 220 needs to be supported, the hinge plate 2042 is vertically aligned with the fixed plate 2041, and then the I-shaped plug block 2044 is inserted into the two slots 2043, so that the plug plates on both sides of the I-shaped plug block 2044 abut against the fixed plate 2041 and the hinge plate 2042, so that the hinge plate 2042 cannot rotate, and the fixed plate 2041 and the hinge plate 2042 cannot separate by themselves. A handle 2045 is provided to facilitate moving the I-shaped plug block 2044.

[0045] When there is no need to support the adjustment assembly 220, the handle 2045 is pulled to drive the I-shaped plug block 2044 to move, thereby separating the plug block from the fixed plate 2041 and the hinge plate 2042, so that the hinge plate 2042 is free from restriction and can be rotated. By rotating the hinge plate 2042, the hinge plate 2042 is separated from the adjustment assembly 220.

[0046] like Figure 5 As shown, the adjustment assembly 220 includes a threaded rod 221, a limiting ring 222 and a rotating ring 223. The threaded rod 221 penetrates the second fixing ring 208 installed inside the second cylinder 207, and the threaded rod 221 is threadedly connected with the thread groove 2054; the limiting ring 222 is sleeved on the threaded rod 221, and the limiting ring 222 is rotatably connected with the second fixing ring 208, which can limit and support the threaded rod 221, and ensure the stability of the threaded rod 221 during the rotation process.

[0047] The rotating ring 223 is rotatably sleeved on the threaded rod 221 , and the rotating ring 223 contacts the supporting groove on the hinge plate 2042 ; the width of the rotating ring 223 is ten times the thickness of the hinge plate 2042 .

[0048] Specifically, when the distance between the second cylinder and the first cylinder needs to be adjusted, the threaded rod 221 is rotated to thread the threaded rod 221 with the thread groove 2054, so that the threaded rod 221 moves into the thread groove 2054, or moves away from the thread groove 2054, thereby driving the limit ring 222 to move, thereby driving the second cylinder to move, and then adjusting the distance between the second cylinder and the first cylinder. The support groove on the hinge plate 2042 supports the rotating ring 223, thereby improving the stability of the rotating ring 223 and the threaded rod 221.

[0049] like Figure 3 As shown, the driving mechanism 300 includes a first mounting seat 301, a motor 302 and a square plug rod 303. The first mounting seat 301 is mounted on the top surface of the carrier plate 100; the motor 302 is mounted on the first mounting seat 301; the square plug rod 303 is mounted on the power output shaft of the motor 302, and the square plug rod 303 is plugged into the first square groove 2052.

[0050] Specifically, the motor 302 serves as a power source to provide power for the driving device to operate. The square plug rod 303 is plugged into the first square groove 2052 on the connecting piece 205, and the power of the motor 302 can be transmitted to the connecting piece 205, so that the connecting piece 205 drives the first cylinder 206 to rotate, and then drives the rubber column 600 to rotate, thereby meeting the requirements for processing the rubber column 600 at different angles during cutting and trimming, and ensuring the normal operation of the device.

[0051] like Figure 7 As shown, the cutting and trimming mechanism 500 includes a mounting frame 501 , a laser cutting machine 511 , an adjusting rod 521 , a trimming piece 522 , a rotating disk 523 and a guide rod 524 .

[0052] The mounting frame 501 is mounted on the vertical plate 102; the laser cutting machine 511 is mounted on the top surface of the mounting frame 501, and the laser cutting head 512 of the laser cutting machine 511 extends to the bottom of the mounting frame 501; the adjusting rod 521 passes through the mounting frame 501 and is threadedly connected to the mounting frame 501; the trimming piece 522 is mounted at the lower end of the adjusting rod 521, and the trimming piece 522 is a grinding block, which can grind off the protrusions on the outer surface of the rubber column 600 to achieve the purpose of trimming; the turntable 523 is mounted on the upper end of the adjusting rod 521; the guide rod 524 is mounted on the upper end of the trimming piece 522, passes through the mounting frame 501 and is slidably connected to the mounting frame 501.

[0053] Specifically, the laser cutting machine 511 can cut the rubber column 600 through the laser cutting head 512, which has the advantages of high cutting accuracy and high efficiency. The adjusting rod 521 is threadedly connected to the mounting frame 501. By rotating the adjusting rod 521, the height of the trimming piece 522 can be adjusted to meet the trimming requirements of rubber columns 600 of different thicknesses. The trimming piece 522 is a grinding block, which is used to trim the edge of the rubber column 600 before cutting to improve product quality.

[0054] Working principle: When in use, the handle 2045 is pulled to move the I-shaped plug 2044 to separate the I-shaped plug 2044 from the hinge plate 2042 and the fixed plate 2041, and then the hinge plate 2042 is rotated to separate the hinge plate 2042 from the rotating ring 223, and then the rubber column 600 to be processed is put on the arc plate 211 of the multiple inner support assemblies 210.

[0055] Then, by rotating the threaded rod 221, the threaded rod 221 moves into the threaded groove 2054. The movement of the threaded rod 221 will drive the limit ring 222 and the second cylinder 207 to move, so that the distance between the second cylinder 207 and the first cylinder 206 is shortened. When the second cylinder 207 moves, it will drive the hinge rod 212 to move, and then drive the arc plate 211 to move, so that the arc plate 211 contacts the inner wall of the rubber column 600, so that multiple arc plates 211 jointly support the inner wall of the rubber column 600.

[0056] Then turn to the hinge plate 2042, so that the support groove on the hinge plate 2042 contacts the rotating ring 223, and then the hinge plate 2042 supports the rotating ring 223, and then, the I-shaped plug 2044 is plugged into the two slots 2043, so that the I-shaped plug 2044 connects the fixed plate 2041 and the hinge plate 2042 together, so that the hinge plate 2042 cannot rotate.

[0057] By rotating the turntable 523 , the adjusting rod 521 is driven to rotate and move downward, thereby causing the trimming piece 522 to move downward, and thereby causing the trimming piece 522 to contact the outer surface of the rubber column 600 .

[0058] Then, the motor 302 is started, so that the power output shaft of the motor 302 drives the square plug rod 303 to rotate, and the square plug rod 303 is plugged and matched with the first square groove 2052 on the connecting member 205, so that the connecting member 205 drives the first cylinder 206 to rotate, and then drives the rubber column 600 to rotate. Since the outer surface of the rubber column 600 is in contact with the trimming member 522, the trimming member 522 will trim the rotating rubber column 600 to improve the quality of the rubber column 600.

[0059] Then, the laser cutting machine 511 is started to cut the rotating rubber column 600 through the laser cutting head 512, so that a part of the rubber column 600 is cut and separated, and the separated part forms a rubber sealing ring.

[0060] At the same time, when the fixed column 2051 in the connecting member 205 rotates, it will drive the first bevel gear 2055 to rotate, and then mesh and drive the second bevel gear 403 to rotate. The second bevel gear 403 will drive the disc 404 to rotate through the reducer 402. The round pin 405 on the disc 404 intermittently cooperates with the guide groove 1032 on the fixed member 103 to push the movable plate 201 to move horizontally intermittently. The locking arc plate 406 intermittently cooperates with the arc groove 1033 on the fixed member 103 to lock the position of the movable plate 201, so as to realize the intermittent horizontal movement of the fixing mechanism 200 and the rubber column 600. Therefore, the trimming member 522 trims the other positions of the rubber column 600, and the laser cutting head 512 of the laser cutting machine 511 cuts the other positions of the rubber column 600, so as to obtain multiple rubber sealing rings.

[0061] After the cutting is completed, the motor 302 and the laser cutter 511 are turned off. The threaded rod 221 is rotated to move the threaded rod 221 away from the thread groove 2054, so that the movement of the threaded rod 221 drives the limit ring 222 and the second cylinder 207 to move, so that the distance between the second cylinder 207 and the first cylinder 206 increases. When the second cylinder 207 moves, the hinge rod 212 is driven to move, and then the arc plate 211 is driven to move, so that the arc plate 211 and the inner wall of the rubber column 600 are no longer in contact.

[0062] Then, by pulling the handle 2045, the I-shaped plug block 2044 is moved to separate the I-shaped plug block 2044 from the fixed plate 2041 and the hinge plate 2042, and then the hinge plate 2042 is rotated to separate the hinge plate 2042 from the rotating ring 223, and then the multiple rubber sealing rings are removed from the multiple arc plates 211.

[0063] By providing the square rod 303 , the fixing column 2051 and the slot 2043 , when the fixing column 2051 moves away from the motor 302 , the power of the motor 302 can still be transmitted to the fixing column 2051 through the square rod 303 .

[0064] As an extension, other cutting devices, such as water jet cutting, can also be used to cut the rubber column 600. If laser is used to cut the rubber column 600, the cut piece of the rubber sealing ring can be polished to improve the quality of the rubber sealing ring.

[0065] Example 2: Figure 8 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: The adjustment assembly 220 further includes a second square groove 224 , which is formed on the threaded rod 221 . The second square groove 224 is plug-fitted with the handle 2045 .

[0066] Working principle: When the threaded rod 221 needs to be rotated, the handle 2045 can be pulled to drive the I-shaped plug block 2044 to move, so that the I-shaped plug block 2044 is separated from the hinge plate 2042 and the fixed plate 2041, and then the handle 2045 is inserted into the second square groove 224 of the threaded rod 221 to connect the I-shaped plug block 2044 to the threaded rod 221, thereby increasing the force arm of the threaded rod 221 and rotating the threaded rod 221 more effortlessly.

[0067] Example 3: Figure 7 As shown, when other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that the trimming member 522 is a scraper, which can scrape off the protrusions on the outer surface of the rubber column 600 to achieve the purpose of trimming.

[0068] Example 4: Figure 1-Figure 7 As shown, a method for using an automatic cutting and trimming device for a rubber sealing ring comprises the following steps: Step 1: Put the rubber column 600 on the arc-shaped plates 211 of the multiple inner support assemblies 210, shorten the distance between the first cylinder 206 and the second cylinder 207 by rotating the threaded rod 221, and then drive the arc-shaped plate 211 to move through the hinge rod 212, so that the arc-shaped plate 211 is in close contact with the inner wall of the rubber column 600, and fix the rubber column 600 on the multiple arc-shaped plates 211; Step 2: Rotate the hinge plate 2042 so that the hinge plate 2042 is directly above the fixed plate 2041, and connect the hinge plate 2042 to the fixed plate 2041 through the I-shaped plug block 2044, so that the hinge plate 2042 supports the rotating ring 223; Step 3: Start the motor 302, and transmit power to the connecting member 205 through the square plug rod 303, thereby driving the rubber column 600 to rotate; Step 4: While the rubber column 600 is rotating, the outer surface of the rubber column 600 is trimmed by the trimming piece 522; the laser cutting machine 511 is started, and the rotating rubber column 600 is cut by the laser cutting head 512 to form a rubber sealing ring; Step 5: Under the drive of the driving mechanism 300, the connecting member 205 drives the first bevel gear 2055 to rotate, and then drives the input shaft of the reducer 402 to rotate through the meshing second bevel gear 403, and the output shaft of the reducer 402 drives the disc 404 to rotate, and the round pin 405 on the disc 404 intermittently cooperates with the guide groove 1032 on the fixing member 103 to push the movable plate 201 to move horizontally intermittently, so that the fixing mechanism 200 and the rubber column 600 move horizontally intermittently; through the intermittent movement and continuous processing process, the trimming and cutting of the entire rubber column 600 are completed to obtain multiple rubber sealing rings; Step 6: Turn off the motor 302 and the laser cutting machine 511 to stop the processing; adjust the distance between the first cylinder 206 and the second cylinder 207 by rotating the threaded rod 221 to separate the arc plate 211 from the inner wall of the rubber column 600; then separate the I-shaped slider from the fixed plate 2041 and the hinge plate 2042, and then rotate the hinge plate 2042, and then remove the processed rubber sealing ring from the inner support assembly 210; Step 7: Clean the debris and residue inside the device and prepare for the next processing.
