Description

Technical Field

[0001] The invention relates to the field of rubber sealing component production, in particular to an automatic production line for engine rubber sealing components. Background Art

[0002] Rubber seals are a type of rubber product made of rubber and used for sealing and leak-proofing. They are usually in the shape of a ring. In the engine, rubber seals play a huge role in filling the gaps between parts to prevent leakage of compressed gas or gas and ensure the normal operation of the engine. The production process of engine rubber seals is relatively complex, and multiple processing steps are required from rubber to seal molding. Rubber seals are often processed on a production line.

[0003] The existing production line of engine rubber seals, such as the processing equipment for environmentally friendly rubber seals proposed in patent application number "CN201811293415.7", is used for grinding rubber seals, including structures such as a rubber ring fixing disk, a motor support platform and a grinding disc. The other ends of the four groups of tension springs are respectively fixedly connected to one side of the four motor support platforms. By providing a rubber ring fixing disk, when using this device to grind the rubber ring, the rubber ring to be polished is respectively put on the outside of the circular disk of the rubber ring fixing disk of the corresponding size. The tension spring will drag the motor support platform to move inward. At this time, the rubber ring on the outside of the rubber ring fixing disk contacts the outside of the grinding disc, and then the motor is turned on to drive the rubber ring fixing disk and the rubber ring to rotate. The rubber ring can also support the inside of the rubber ring during grinding.

[0004] However, there are still certain defects in the prior art. It can only grind the rubber ring and needs to be equipped with other rubber processing equipment to form a production line. The equipment is too independent and it is difficult to match other equipment to generate a production line. It also does not have the function of automatic feeding of rubber rings, the degree of processing automation is low, and the processing efficiency is low.

DETAILED DESCRIPTION

[0043] 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.

[0044] The invention discloses an automated production line for engine rubber seals, which belongs to the field of intelligent manufacturing equipment industry and is a device used for processing and producing engine rubber seals. The production line has a stable grinding mechanism, coordinated working procedures, and full automation, thereby improving the production efficiency of engine rubber seals.

[0045] An automated production line for engine rubber seals, such as Figure 1-Figure 9 As shown, it includes a machine base 1, and the upper end of the machine base 1 is fixedly connected with a molding mechanism 6 for connecting the rubber strip joints, the molding mechanism 6 has a heating function, and the joints are heated and melted to form the connection, and a grinding mechanism 7 is used for grinding the rubber seal, and the grinding mechanism 7 grinds the looped rubber seal so that the burrs on the surface of the rubber seal are processed.

[0046] The forming mechanism 6 includes a rotating column 61, which is rotatably installed on the upper end of the machine base 1. The machine base 1 has a structure for driving the rotating column 61 to rotate. The rotating column 61 is located between the pulling mechanism 4 and the grinding mechanism 7. The side wall of the rotating column 61 is fixedly connected to multiple groups of extrusion and heating mechanisms. One side of the lower end of the multiple groups of extrusion and heating mechanisms is fixedly connected to an expansion and discharge mechanism, and the expansion and discharge mechanism cooperates with the extrusion and heating mechanism.

[0047] The rotation of the rotating column 61 drives the multiple groups of extrusion and heating mechanisms to rotate. When the extrusion and heating mechanism is facing the docking structure, the extrusion and heating mechanism opens, and the docking mechanism 5 places the rubber strip inside the extrusion and heating mechanism. The extrusion and heating mechanism receives the rubber strip and closes to heat and pressurize. When the extrusion and heating mechanism receiving the rubber seal rotates 90 degrees and opens, the rubber seal formed inside is cooled. After rotating 90 degrees again, it faces the polishing mechanism 7, and the expansion and discharging mechanism starts to expand, propping up the rubber seal, making it easier to transfer the rubber seal to the polishing mechanism 7.

[0048] The grinding mechanism 7 includes a mounting seat 72, which is slidably mounted on the upper end of the machine base 1. An expansion feeding mechanism is rotatably mounted on the mounting seat 72. A cylinder 74 for rubber sealing is installed in the middle of the expansion feeding mechanism. The expansion feeding mechanism is accommodated and matched with the side wall of the cylinder 74, and the expansion feeding mechanism is docked with the expansion discharging mechanism. A grinding roller mechanism is slidably connected to the mounting seat 72, and the grinding roller mechanism is matched with the side wall of the cylinder 74.

[0049] When the mounting seat 72 moves, it can be close to or away from the molding mechanism 6. When it is close, the expansion feeding mechanism is in a closed state and fits with the side wall of the cylinder 74 until the cylinder 74 enters the expanded expansion discharging mechanism after expansion, thereby facilitating the transfer of the rubber seal on the molding mechanism 6. After the transfer, the grinding roller grinds the rubber seal.

[0050] The expansion mechanism can not only transport the rubber seal, making it easier to transfer the rubber seal to the polishing mechanism 7, but also expand the seal to test the structural firmness of the seal, thereby reducing the defective rate of the engine rubber seal production.

[0051] During operation, the butted rubber strips are sent to the inside of the extrusion and heating mechanism so that the butted parts are heated and formed. During the rotation of the forming mechanism 6, the rubber seal cools down and the rubber strip becomes a rubber ring. When the rubber ring is facing the grinding mechanism 7, the expansion and discharge mechanism operates to open the rubber ring. The grinding mechanism 7 approaches the forming mechanism 6 so that the expansion feeding mechanism is inserted into the expanded rubber ring. The expansion feeding mechanism expands again to hold up the rubber ring. The expansion and discharge mechanism is closed, and the grinding mechanism 7 retreats. The expansion feeding mechanism takes the rubber ring out of the forming mechanism 6 and retracts into the side wall of the cylinder 74 so that the rubber ring is sleeved on the cylinder 74. The grinding roller mechanism approaches until the grinding roller mechanism is close to the rubber ring on the side wall of the cylinder 74. The cylinder 74 is controlled to rotate and the rubber ring is polished by the grinding roller mechanism. The grinding mechanism 7 of this production line is stable, the processes are coordinated, and the whole process is automated, so that the production efficiency of engine rubber seals is high.

[0052] like Figure 1-Figure 2 As shown, the machine base 1 is fixedly connected with a rubber extruder 2 for extruding rubber into strips. The rubber extruder 2 is a prior art device. The cutting mechanism 3 for cutting the rubber strips includes a U-shaped frame and a lifting cutting blade. The lifting cutting blade cuts the rubber strips so that the rubber strips are cut. The cutting time is controlled and adjusted by an external controller. The pulling mechanism 4 for pulling the rubber strips pulls the end of the discharged rubber strip so that the rubber strips will not fall and contact the work surface. The docking mechanism 5 for docking the two ends of the rubber strips is used. The docking mechanism 5 receives the rubber strips so that the rubber strips are docked in a ring shape.

[0053] The cutting mechanism 3 is located between the rubber extruder 2 and the docking mechanism 5. When the rubber strip is clamped by the docking mechanism 5, the cutting mechanism 3 cuts the rubber between the docking mechanism 5 and the rubber extruder 2. The pulling mechanism 4 is located between the docking mechanism 5 and the molding mechanism 6, and one end of the pulling mechanism 4 is located below the discharge end of the rubber extruder 2. The pulling mechanism 4 pulls the end of the rubber strip so that the rubber strip is placed horizontally between the docking mechanism 5 and the molding structure to prevent the rubber strip from falling to the ground. At the same time, the pulling height is the same as the height of the discharge port of the rubber extruder 2 to prevent the middle part of the rubber strip from bending downward during the pulling process. The grinding mechanism 7 is located on the side of the molding mechanism 6 away from the docking mechanism 5. The rubber strip enters the grinding mechanism 7 for processing after passing through the molding mechanism 6.

[0054] Rubber is added to the rubber extruder 2. The rubber extruder 2 is provided with multiple groups of discharge ports, which are arranged in a linear array. The rubber extruder 2 extrude multiple rubber strips at the same time. The pulling mechanism 4 is close to the rubber extruder 2, and the ends of the multiple rubber strips are pulled to a certain length at the same time. Then, the docking mechanism 5 is close to the rubber strip, and the internal clamping plate 531 is opened to clamp the two ends of the rubber strip. The cutting mechanism 3 cuts the rubber strip between the clamping plate 531 and the rubber extruder 2. The clamping plate 531 is close and rotated 180 degrees to dock the two ends of the rubber strip. After docking, the clamping plate 531 moves forward, and the docked rubber seal is sent to the molding mechanism 6.

[0055] The pulling mechanism 4 includes an electric slide 41 , which is fixed to the upper end of the machine base 1 , and a clamping mechanism 42 is slidably connected to the electric slide, and the clamping mechanism 42 is used to clamp the rubber extruded by the rubber extruder 2 .

[0056] An electric slide 41 (model TOYO-GTH8) is located between the docking mechanism 5 and the molding structure, and its installation direction is the same as the discharge direction of the rubber extruder 2. The clamping mechanism 42 is a prior art, and a driving device is used to control two groups of flat plates to clamp the ends of multiple groups of rubber strips. The length of the clamping mechanism 42 is greater than the length of the discharge head of the rubber extruder 2, and the multiple groups of rubber strips discharged from the rubber extruder 2 can be clamped. After clamping, the electric slide 41 controls the clamping mechanism 42 to retreat, so that the clamping mechanism 42 pulls the rubber strip to one end, which is convenient for the docking mechanism 5 to transfer.

[0057] like Figure 1-Figure 4As shown, the docking mechanism 5 includes a base 51, which is fixedly connected to the upper end of the machine base 1, and an electric push rod 511 (model DYTP450- / 110) is fixedly connected to the rear end of the base 51. A moving frame 52 is slidably connected to the base 51, and the output end of the electric push rod 511 is fixedly connected to the back of the moving frame 52. When the electric push rod 511 runs, it pushes the moving frame 52 to slide on the base 51, so that the moving frame 52 is close to the molding mechanism 6, which is convenient for the docking structure to transfer the rubber strip to the molding mechanism 6. The sliding path of the moving frame 52 has a length limit to prevent the moving frame 52 from detaching from the base 51.

[0058] The movable frame 52 is horizontally slidably connected to the inner frame 521, and a double-headed screw 522 is rotatably installed inside the inner frame 521. Both ends of the double-headed screw 522 are threadedly connected to the connecting frame 535. The two groups of connecting frames 535 are slidably connected to the inner frame 521. One end of the two groups of connecting frames 535 is rotatably connected to the clamping frame 53. The clamping frame 53 is rotatably connected to two groups of clamping plates 531. The two groups of clamping plates 531 are symmetrical and extrusion-fitted. The double-headed screw 522 starts to split from the center, and the thread directions on both sides are opposite, so that the pile head screw rotates, driving the two groups of connecting frames 535 to move in opposite directions.

[0059] Two sets of electric telescopic structures 523 are fixedly connected to the upper end of the inner frame 521, and racks 524 are fixedly connected to the upper ends of the two sets of electric telescopic structures 523. The two sets of racks 524 pass through the back of the moving frame 52. Gear driving mechanisms 525 are fixedly connected to both sides of the moving frame 52. The two sets of gear driving mechanisms 525 are respectively meshed with the two sets of racks 524 for transmission.

[0060] The electric telescopic structure 523 has an electric telescopic drive component (electric telescopic rod 533 and other structures) inside, which can control the inner frame 521 to move up and down to a certain height. The motor used to drive the double-headed screw 522 to rotate is installed on the outside of the moving frame 52. A rectangular opening is opened on the side wall of the moving frame 52 to facilitate communication. The width of the rectangular opening is relatively large, and its width is greater than the width of the connection structure between the motor and the double-headed screw 522, so that the inner frame 521 and the motor can move up and down within a certain space in the rectangular opening.

[0061] The gear drive mechanisms in this article are all composed of motors and gears, which belong to the prior art. The center of the gear is fixedly connected to the output end of the motor to achieve the effect of meshing drive, indirectly control the operation of other structures, and reduce motor damage. The rack 524 slides and is connected with the back of the moving frame 52. The gear drive mechanism 525 meshes with the rack 524, so that the rack 524 moves back and forth, controls the inner frame 521 to move back and forth, and cooperates with the electric push rod 511 to push in two stages, so that the structure on the inner frame 521 can move forward or backward in two stages.

[0062] like Figure 3-Figure 4As shown, two groups of electric telescopic rods 533 are fixedly connected inside the clamp frame 53. The output ends of the two groups of electric telescopic rods 533 are rotatably connected to connecting rods 532. The two groups of connecting rods 532 are symmetrical to each other, and the ends of the two groups of connecting rods 532 are rotatably connected to the two groups of clamping plates 531 respectively. The two groups of connecting rods 532 are used to pull the two groups of clamping plates 531 to rotate.

[0063] The output end of the electric telescopic rod 533 (model TA-01-30) is extended and retracted, pulling the connecting rod 532, so that the connecting rod 532 pulls the clamping plate 531 to rotate. The two sets of electric telescopic rods 533 and connecting rods 532 control the opening and closing of the two sets of clamping plates 531, so that the two sets of clamping plates 531 clamp the rubber strip.

[0064] A gear disc rotating seat 534 is fixedly connected to one end of the clamping frame 53 close to the inner frame 521 , and the gear disc rotating seat 534 is rotatably connected to the connecting frame 535 , and a second gear driving mechanism 536 is fixedly connected to the connecting frame 535 , and the second gear driving mechanism 536 meshes with the gear disc rotating seat 534 for transmission.

[0065] The clamping frame 53 is installed on the connecting frame 535 through the gear disc rotating seat 534. The gear driving mechanism 2 536 is engaged with the gear disc rotating seat 534, so that the gear disc rotating seat 534 drives the clamping frame 53 to rotate. The clamping plate 531 in the clamping frame 53 clamps the rubber strip and turns it 180 degrees, so that the two ends of the rubber strip can be connected.

[0066] When the docking mechanism 5 is in operation, the clamping plates 531 in the two groups of clamping frames 53 are controlled to open, the double-headed screw 522 rotates to control the two groups of clamping frames 53 to move away from each other, the electric push rod 511 pushes the moving frame 52 forward, so that the clamping plates 531 clamp the two ends of the pulled rubber strip, and the cutting mechanism 3 cuts the rubber strip. After cutting, the length of the two ends of the rubber strip from the clamping plates 531 is 1-2 cm, which is convenient for the rubber strip to dock. Then, the double-headed screw 522 controls the two groups of clamping plates 531 to approach, and at the same time, the gear drive structure 2 controls the clamping frame 53 to rotate 180 degrees, so that the two ends of the rubber strip are in contact, and the gear drive structure 1 controls the rack 524 to slide, so that the clamping plates 531 clamp the rubber strip and move forward again, and the docking position of the rubber strip is sent to the molding mechanism 6. Then the docking mechanism 5 retreats and resets to wait for the next repetitive process.

[0067] like Figure 1-Figure 2 , Figure 5-Figure 6As shown, the extrusion heating mechanism includes a fixed seat 62, which is fixedly connected to the side wall of the rotating column 61, a cylinder 621 is fixedly connected inside the fixed seat 62, a movable plate 622 is fixedly connected to the output end of the cylinder 621, a slide seat 63 is fixedly connected to one side of the fixed seat 62, an upper pressing plate 65 and a lower pressing plate 66 are slidably connected to the slide seat 63, an L-shaped plate 64 is rotatably connected to the side of the slide seat 63, a slot 623 is provided on the fixed seat 62, one end of the L-shaped plate 64 passes through the slot 623 and is rotatably connected to the side wall of the movable plate 622, and the other end is rotatably connected to the side walls of the upper pressing plate 65 and the lower pressing plate 66 respectively, an upper heating plate 651 is fixedly connected to the upper end of the upper pressing plate 65, and a forming heating plate 652 is fixedly connected to the lower pressing plate 66, the forming heating plate 652 is extruded and matched with the lower pressing plate 66, and the connecting holes at both ends of the L-shaped plate 64 are both elliptical to prevent the L-shaped plate 64 from getting stuck.

[0068] The cylinder 621 (model TN16X20S) drives the movable plate 622 to move, and the movable plate 622 pulls one end of the L-shaped plate 64 to rotate the L-shaped plate 64, and the other end of the L-shaped plate 64 drives the upper pressing plate 65 or the lower pressing plate 66 to move, so that the upper pressing plate 65 and the lower pressing plate 66 are moved away from or closer to each other.

[0069] When the docking mechanism 5 is in contact with the molding structure, the docking structure can first dock the two ends of the rubber strip at a certain distance, and then the inner frame 521 is lifted by the electric telescopic structure 523, and the clamping plate 531 is close to the upper heating plate 651, and the two ends of the rubber strip are first contacted with the two sides of the upper heating plate 651, so that the two ends of the rubber strip are heated and melted, and the clamping plate 531 retreats, and the two groups of inner frames 521 are controlled to move to the two ends of the rubber strip to contact, so that the two ends of the rubber strip are bonded, and the electric telescopic structure 523 controls the clamping plate 531 to descend, and at the same time the inner frame 521 moves forward, and the docking position of the rubber strip is sent to between the upper pressing plate 65 and the lower pressing plate 66, and the upper pressing plate 65 and the lower pressing plate 66 are merged, and the docking position is heated and shaped for the second time through the molding heating plate 652, so that the two ends of the rubber strip are firmly connected.

[0070] like Figure 5-Figure 6 As shown, the expansion discharging mechanism includes an extension plate 662, and the extension plate 662 is provided with three groups. The three groups of extension plates 662 are all fixedly connected to the side of the lower pressing plate 66. A groove 661 is opened in the middle of one side of the lower pressing plate 66. A worm 664 is rotatably connected in the middle of the groove 661. A gear driving mechanism 663 for driving the worm 664 to rotate is fixedly connected to one side of the inner part of the groove 661.

[0071] The groove 661 is internally rotatably connected with three groups of extrusion mechanisms, and the side walls of the three groups of extrusion mechanisms are all in transmission cooperation with the side walls of the worm 664. The three groups of extension plates 662 are all slidably connected with expansion rods 667, and the three groups of extrusion mechanisms are respectively in extrusion cooperation with the three groups of expansion rods 667.

[0072] Before the rubber strip enters the extrusion heating mechanism, the expansion rod 667 is closed, occupying a small space. After the rubber strip enters the extrusion heating mechanism, this mechanism closes to process the rubber strip, and the expansion rod 667 is located in the rubber ring. Then the molding mechanism 6 rotates. After the molding mechanism 6 rotates 90 degrees, the extrusion heating mechanism opens, the rubber seal gradually cools down, and the rubber strip becomes a rubber ring. When the molding mechanism 6 rotates until the rubber ring is facing the polishing mechanism 7, the expansion discharge mechanism operates.

[0073] When the expansion discharging mechanism is running, the gear driving mechanism three 663 controls the rotation of the worm 664 (a toothed ring is provided on the bottom side wall of the worm 664, which meshes with the gear driving mechanism three 663). The rotation of the worm 664 drives the three groups of extrusion mechanisms to rotate, and the three groups of extrusion mechanisms squeeze the three groups of expansion rods one 667 to expand the rubber ring.

[0074] like Figure 6 As shown, the extrusion mechanism includes a worm wheel 665, which is rotatably connected to the groove 661, and the side wall of the worm wheel 665 is in transmission cooperation with the side wall of the worm 664, and a bent plate 666 is fixedly connected to one side of the worm wheel 665, and the end of the bent plate 666 is in extrusion cooperation with the expansion rod 667;

[0075] The three groups of extension plates 662 are all fixedly connected with columns 6621, and the three groups of columns 6621 respectively penetrate one end of three groups of expansion rods 667. The side walls of the three groups of columns 6621 are all sleeved with springs 6622, one end of the spring 6622 is fixedly connected to the inner wall of the extension plate 662, and the other end is fixedly connected to the expansion rod 667. The spring 6622 is always in a compressed state.

[0076] The worm 664 drives the worm wheel 665 to rotate, causing the bent plate 666 to flip, and the end of the bent plate 666 squeezes the expansion rod 667, so that the multiple groups of expansion rods 667 are opened, and the worm 664 rotates in the opposite direction, and the bent plate 666 rotates in the opposite direction, the bent plate 666 does not squeeze the expansion rod 667, and the spring 6622 squeezes the expansion rod 667, so that the multiple groups of expansion rods 667 are closed.

[0077] like Figure 1-Figure 2 , Figure 7-Figure 9 As shown, the upper end of the machine base 1 is fixedly connected with an electric slide 2 71 (model: mcs220), the mounting seat 72 is slidably connected to the electric slide 2 71, the mounting seat 72 is driven to move by the electric slide 2 71, and the expansion feeding mechanism includes a turntable 73, the turntable 73 is rotatably mounted on the mounting seat 72, a cross slide rail 732 is fixedly connected to one side of the turntable 73, a reciprocating rotating seat 731 is rotatably connected to the middle of the turntable 73, the axis of the reciprocating rotating seat 731 is aligned with the center of the cross slide 732, the four groups of end portions of the cross slide 732 are all slidably connected with sliding seats 733, the four groups of sliding seats 733 and the reciprocating rotating seat 731 are all rotatably connected with connecting rods 734, and the four groups of sliding seats 733 are all fixedly connected with expansion rods 2 738;

[0078] A gear wheel 735 is fixedly connected to the back of the turntable 73, and the gear wheel 735 is rotatably connected to the back of the mounting seat 72. A gear driving mechanism 737 is fixedly connected to the back of the mounting seat 72, and the gear driving mechanism 737 is meshed with the gear wheel 735 for transmission. A servo motor 736 is fixedly connected to the middle of the gear wheel 735, and the output end of the servo motor 736 passes through the gear wheel 735 and is fixedly connected to the center of the reciprocating rotating seat 731.

[0079] The servo motor 736 (model 110ST-M05030) controls the reciprocating rotating seat 731 to rotate. The reciprocating rotating seat 731 pulls the sliding seat 733 through the connecting rod 734, so that the sliding seat 733 slides along the cross slide rail 732, thereby controlling the opening or closing of multiple groups of expansion rods 2 738, and the gear drive mechanism 4 737 controls the rotation of the gear wheel 735, so that the turntable 73 rotates as a whole.

[0080] When the rubber ring is transferred to face the grinding mechanism 7, the expansion and discharging mechanism operates to stretch the rubber ring, and the grinding mechanism 7 is close to the molding mechanism 6, so that the expansion feeding mechanism is inserted into the expanded rubber ring, and the four groups of expansion rods 2 738 expand to prop up the rubber ring, and the expansion and discharging mechanism closes, and the grinding mechanism 7 retreats, and the four groups of expansion rods 2 738 take the rubber ring away from the molding mechanism 6, and the rubber ring is transferred to the grinding mechanism 7.

[0081] like Figure 1-Figure 2 , Figure 7-Figure 9 As shown, the cylinder 74 is fixedly connected to the middle part of the turntable 73, the cylinder 74 is coaxial with the reciprocating rotating seat 731, the cylinder 74 is located between the multiple groups of expansion rods 738, and the side wall of the cylinder 74 is provided with four groups of accommodating grooves 741. The four groups of expansion rods 738 are respectively matched with the four groups of accommodating grooves 741, and the cylinder 74 is matched with the middle part of the expansion discharging mechanism.

[0082] When the four groups of expansion rods 2 738 bring the rubber ring out of the forming mechanism 6 and the rubber ring is transferred to the grinding mechanism 7, the four groups of expansion rods 2 738 are retracted into the accommodating groove 741 on the side wall of the cylinder 74, so that the rubber ring is sleeved on the cylinder 74, and the grinding roller mechanism approaches until the grinding roller mechanism is close to the rubber ring on the side wall of the cylinder 74, and the turntable 73 is controlled to rotate, and the rubber ring is ground by the grinding roller mechanism.

[0083] like Figure 1-Figure 2 , Figure 7-Figure 8 As shown, the grinding roller mechanism includes a connecting member 752, which is slidably connected to the mounting seat 72. A pushing member 751 (a device that electrically drives the connecting member 752 to slide) is fixedly connected to the back of the mounting seat 72. The output end of the pushing member 751 is fixedly connected to the connecting member 752. The other end of the connecting member 752 is fixedly connected to a grinding roller 75, and the grinding roller 75 is closely matched with the side wall of the cylinder 74.

[0084] The pusher 751 runs, pushing the connecting member 752 to slide, so that the grinding roller 75 fits the rubber ring on the side wall of the cylinder 74. When the turntable 73 rotates, the grinding roller 75 grinds the surface of the rubber ring without the need for the spring 6622 to pull. The structure is stable and the grinding effect is good. Multiple seals can be processed at the same time, and the processing efficiency is high.

[0085] The connecting member 752 is electrically pushed close to the cylinder 74 by the pushing member 751, so that the grinding roller 75 can grind the rubber seal on the side wall of the cylinder 74. Compared with the prior art, no spring pulling is required, the structure is stable, and the grinding effect is good.

[0086] The working principle of an automatic production line for engine rubber seals provided by the present invention is as follows:

[0087] During operation, the rubber extruder 2 extrudes multiple rubber strips at the same time, the pulling mechanism 4 approaches the rubber extruder 2, and pulls the ends of the multiple rubber strips to a certain length at the same time, then the docking mechanism 5 approaches the rubber strip, the internal clamping plate 531 opens, clamps the two ends of the rubber strip, and the cutting mechanism 3 cuts the rubber strip between the clamping plate 531 and the rubber extruder 2, the clamping plate 531 approaches and rotates 180 degrees, so that the two ends of the rubber strip are spaced a certain distance apart, and then the inner frame 521 is lifted by the electric telescopic structure 523, and the clamping plate 531 approaches. Approach the upper heating plate 651, first contact the two ends of the rubber strip with the two sides of the upper heating plate 651, so that the two ends of the rubber strip are heated and melted, the clamping plate 531 retreats, and then controls the two groups of inner frames 521 to move until the two ends of the rubber strip are in contact, so that the two ends of the rubber strip are bonded, the electric telescopic structure 523 controls the clamping plate 531 to descend, and at the same time the inner frame 521 moves forward, and the docking position of the rubber strip is sent to between the upper pressing plate 65 and the lower pressing plate 66, the upper pressing plate 65 and the lower pressing plate 66 are merged, and the docking position is heated and shaped again by the molding heating plate 652.

[0088] During the rotation of the molding mechanism 6, the rubber seal cools down and the rubber strip becomes a rubber ring. When the rubber ring is facing the grinding mechanism 7, the expansion and discharge mechanism operates to stretch the rubber ring, and the grinding mechanism 7 approaches the molding mechanism 6, so that the expansion feeding mechanism is inserted into the expanded rubber ring. The expansion feeding mechanism expands again to prop up the rubber ring, the expansion and discharge mechanism closes, and the grinding mechanism 7 retreats. The expansion feeding mechanism takes the rubber ring out of the molding mechanism 6, and the expansion feeding mechanism is retracted into the side wall of the cylinder 74, so that the rubber ring is sleeved on the cylinder 74, and the grinding roller mechanism approaches until the grinding roller mechanism is close to the rubber ring on the side wall of the cylinder 74, and the cylinder 74 is controlled to rotate. The rubber ring is ground by the grinding roller mechanism. The grinding mechanism 7 of this production line is stable, the processes are coordinated, and the whole process is automated, so that the production efficiency of engine rubber seals is high.
