Description

Technical Field

[0001] The present invention relates to the technical field of metal skeleton gasket production, and particularly relates to a metal coil double-sided gluing machine. Background Art

[0002] Metal skeleton gaskets are used for oil circuit seals such as flange surfaces, oil tanker casings, and cylinder heads. They have good sealing performance, excellent oil resistance, and the characteristic of being reusable multiple times, and are favored by various internal combustion engine manufacturers. The existing production process of metal skeleton foamed gaskets is as follows:

[0003] Step 1: Use a slitter to slit the rubber raw material and successively pass through the batching area, cooling and pressure boosting area, etc. to obtain a semi-finished rubber compound after corresponding processes; Step 2: Lift and load the metal coil and successively pass through the grinding area, degreasing area, etc. to obtain a metal skeleton after corresponding processes; Step 3: Load the semi-finished rubber compound into a scraping and coating device to make the semi-finished rubber compound be fixedly scraped and coated on the surface of the metal skeleton; Step 4: The metal skeleton with the semi-finished rubber compound coated on its surface is successively transported through a drying tunnel furnace and a vulcanization tunnel furnace. After the semi-finished rubber compound on the surface of the metal skeleton is dried and vulcanized into rubber, the finished metal skeleton rubber gasket can be obtained.

[0004] Among them, since both the front and back sides of the metal skeleton (relatively thin and in a rolled shape, also called metal coil in the present invention) need to be covered with a layer of rubber, in the actual production process of metal skeleton rubber gaskets, usually the processes of separately scraping and coating the semi-finished rubber compound, drying, and vulcanizing the scraped and coated semi-finished rubber compound are carried out on the front and back sides of the metal skeleton respectively. These two repeated process flows not only consume a large amount of manpower and material resources, but also lengthen the production cycle of the entire gasket and greatly reduce the production efficiency of the gasket.

Subsequently, the coil pulling device 43 on the first frame 41 pulls out the coil that has been dried in the second-layer coil drying tunnel furnace 1 and, in cooperation with the coil guiding roller 44, sends the coil into the coil vulcanization tunnel furnace 2 for the vulcanization treatment of the rubber compound on both the front and back sides of the coil. After that, the coil pulling device 64 on the third frame 61 pulls out the finished coil (finished gasket) that has been vulcanized and fully formed in the coil vulcanization tunnel furnace 2 and sends it through the coil cutting device 63. Finally, the winder 62 winds up the finished coil that has passed through the coil cutting device 63. When the finished coil is wound up to an appropriate length, the coil cutting device 63 cuts the finished coil in front of the winder 62, and at the same time, the unloading trolley 66 unloads the finished coil, and a metal-skeleton foamed rubber gasket with a certain size specification can be obtained.

[0044] Such as Figure 1 , Figure 2As shown in the figure, the mobile device 32 includes a mobile platform 321 in the shape of an H that carries a double-head decoiler 31, multiple pairs of track wheels 322 rotatably arranged on the mobile platform 321 and located on both sides of the double-head decoiler 31 respectively, two guide rails 322a fixed on the ground for each pair of track wheels 322 to roll, a rotating shaft 323 vertically rotating through the mobile platform 321, a worm and gear reduction motor 324 fixed above the mobile platform 321 and driving the rotation of the rotating shaft 323, a gear 325 fixed on the rotating shaft 323 and located below the mobile platform 321, and a rack 326 fixed on one side of the guide rail 322a and meshing with the gear 325. The coil loading trolley 33 is located in the left and right gaps of the mobile platform 321 to feed the double-head with coil materials. The coil loading trolley 33 includes a body 331, multiple pairs of track wheels 332 rotatably arranged on both sides of the body 331 respectively, multiple hydraulic cylinders 333 installed inside the body 331 with the piston rods extending out of the top of the body 331, and a material supporting table 334 fixed at the top of all the hydraulic cylinders 333 and having a V-shaped top. A power device for controlling the rotation of the track wheels 332 is provided inside the body 331, and two guide rails 332a for each pair of track wheels 332 to roll are fixedly arranged on the ground. The guide rails 332a are parallel and located in the middle of the two guide rails 322a.

[0045] By adopting the above mobile device 32, when it is necessary to replace the metal frame coil material, first, the worm and gear reduction motor 324 drives the rotating shaft 323 to rotate, so that the gear 325 meshes and drives the rack 326 on the side of the guide rail 322a. Then, the mobile platform 321 moves along the guide rail 322a under the meshing drive of the gear and the rack 326 until the working position where the coil material on one side of the double-head decoiler 31 is already installed is aligned with the coil material inlet of the first rack 41. Finally, the head of the new coil material and the tail of the old coil material are welded and joined, and the replacement work of the metal frame coil material can be quickly completed. At the same time, the coil loading trolley 33 beside the empty working position on the other side of the double-head decoiler 31 will move along the guide rail 332a closer to the double-head decoiler 31, and the new coil material supported by its material supporting table 334 will be sleeved on the unwinding structure at this working position for the subsequent coil replacement task.

[0046] As Figure 2 、 Figure 5As shown in the figure, at the entrances of the first-layer coil drying tunnel furnace 1, the second-layer coil drying tunnel furnace 1, and the third-layer coil vulcanization tunnel furnace 2, a coil deviation rectifying device 7 is respectively arranged. The coil deviation rectifying device 7 includes a sliding plate 71 movably arranged on the first frame 41 or the second frame 51, a deviation rectifying guide roller 72 horizontally rotatably arranged on the sliding plate 71, a first lead screw 73 rotatably arranged on the first frame 41 or the second frame 51 and parallel to the deviation rectifying guide roller 72, a first nut 74 fixed on the sliding plate 71 and threadedly connected to the lead screw, a first servo motor 75 fixed on the first frame 41 or the second frame 51 and with its output end connected to one end of the first lead screw 73, and a monitoring device 76 installed on the first frame 41 or the second frame 51 to monitor the deviation of the coil conveying. Vertically fixed at the bottom of the sliding plate 71 are a pair of first support plates 711, and the lead screw movably passes through the two first support plates 711, and the first nut 74 is fixed on one of the first support plates 711. Fixed on the first frame 41 or the second frame 51 are a pair of first guide rods 77 that movably pass through the two first support plates 711 at the bottom of the sliding plate 71. The monitoring device 76 controls the start and stop operation of the first servo motor 75 according to the monitoring result. By adopting the above coil deviation rectifying device 7, when the conveying position of the coil is deviated or tilted, the monitoring device 76 will control the first servo motor 75 to work, so that the first servo motor 75 drives the first lead screw 73 to rotate. Then, the first nut 74 at the bottom of the sliding plate 71 will move under the rotation of the first lead screw 73, driving the entire sliding plate 71 to slide along the first guide rod 77. Finally, the deviation rectifying roller at the top of the sliding plate 71 will move horizontally and drive the coil back to the correct conveying position by means of friction.

[0047] As Figure 5 , Figure 6As shown, the first coating device 42 and the second coating device 53 have the same structure. The first coating device 42 or the second coating device 53 includes a glue coating roller 531 rotatably arranged on the first frame 41 or the second frame 51 and parallel up and down, a worm and worm gear reduction motor two 532 for driving the rotation of the glue coating roller 531, a glue blocking bottom plate 533 fixed on the first frame 41 or the second frame 51 and parallel to and close to one side of the side surface of the glue coating roller 531, a pair of glue blocking side plates 534 vertically fixed on the glue blocking bottom plate 533 and one end parallel to and close to the side surface of the glue coating roller 531, a pair of lifting brackets 535 arranged on the first frame 41 or the second frame 51 in a lifting manner, a comma-shaped scraping knife roller 536 with both ends rotatably connected to the two lifting brackets 535 respectively, a lifting assembly 537 for driving the two lifting brackets 535 to move up and down, and an adjusting assembly 538 for adjusting and controlling the rotation of the comma-shaped scraping knife roller 536. The glue blocking bottom plate 533 is located on the side of the glue coating roller 531 away from the coil drying tunnel furnace 1, and the gap between the glue blocking bottom plate 533 and the glue coating roller 531 allows the coil to pass through. The two glue blocking side plates 534 are respectively located on both sides of the coil and close to the side surface of the coil. The comma-shaped scraping knife roller 536 is located above the glue coating roller 531. By adopting the above first coating device 42 or the second coating device 53, when it is necessary to coat glue on the front or back of the coil, first pour the glue into the inclined groove formed by the combination of the glue blocking bottom plate 533 and the two glue blocking side plates 534. Then, the glue adheres to the surface of the coil passing through the gap along the gap between the glue blocking bottom plate 533 and the glue coating roller 531. Finally, the comma-shaped scraping knife roller 536 directly above the glue coating roller 531 will scrape and level the glue on the surface of the coil when the coil passes below it. In this way, the glue is coated on the surface of the coil with a certain thickness.

[0048] As Figure 6As shown in the figure, the lifting assembly 537 includes a pair of servo motors two 537a fixed to the first frame 41 or the second frame 51, a pair of lead screws two 537c respectively and fixedly connected to the output ends of the two servo motors, and a pair of nuts two 537d respectively fixed to the two lifting brackets 535 one and threadedly connected to the two lead screws two 537c. The top end of the lifting bracket 535 is provided with an insertion hole 535b for the lead screw two 537c to movably penetrate, and the nut two 537d is fixed at the entrance of the insertion hole 535b at the top end of the lifting bracket 535. The top end of the lifting bracket 535 is fixedly connected with a pair of vertical guide rods two 535a, and the lead screw two 537c is parallel and located between the two guide rods two 535a. The first frame 41 or the second frame 51 is fixedly provided with a support plate two 537b for the guide rod two 535a and the lead screw two 537c to movably penetrate, and the servo motor two 537a is fixed to the support plate two 537b. By adopting the above-mentioned lifting assembly 537, when it is necessary to control the lifting of the lifting bracket 535, first, the servo motor two 537a drives the lead screw two 537c to rotate. Then, the nut two 537d at the top of the lifting bracket 535 will drive the lifting bracket 535 to move up and down under the rotation of the lead screw two 537c. Finally, the comma-type doctor roll 536 will move away from and close to the coating roller 531 under the lifting movement of the lifting bracket 535, thereby achieving the effect of adjusting the thickness of the rubber material on the surface of the coil.

[0049] As Figure 6 shown in the figure, the adjusting assembly 538 includes a worm one 538a rotatably arranged on a lifting bracket 535, a worm wheel one 538b fixed to one end of the comma-type doctor roll 536 and meshing with the worm one 538a, and an adjusting knob 538c fixed to one end of the worm one 538a. A square groove 535c is arranged on one side of a lifting bracket 535, and the worm one 538a and the worm wheel one 538b are meshed and driven inside the square groove 535c. One side of the lifting bracket 535 is detachably connected with a cover plate 535d covering the square groove 535c. One end of the comma-type doctor roll 536 rotatably penetrates into the square groove 535c and is fixedly connected with the worm wheel one 538b. One end of the worm one 538a rotatably penetrates out of the square groove 535c and is fixedly connected with the adjusting knob 538c. By adopting the above-mentioned adjusting assembly 538, when it is necessary to control the rotation of the comma-type doctor roll 536, first, manually turn the adjusting knob 538c. Then, the adjusting knob 538c drives the worm one 538a to rotate, so that the worm one 538a meshes and drives the worm wheel one 538b. Finally, the worm wheel one 538b rotates relative to the lifting bracket 535 and drives the comma-type doctor roll 536 to rotate itself, thereby achieving the effect of adjusting the scraping direction and scraping angle of the comma-type doctor roll 536. Among them, the square groove 535c and the square cover plate 535d can hide the worm wheel one 538b and the worm one 538a and protect the safe meshing and transmission of the worm wheel one 538b and the worm one 538a.

[0050] As Figure 5, Figure 7 As shown, the structures of the first coil pulling device 43, the second coil pulling device 52, and the third coil pulling device 64 are the same. The first coil pulling device 43, or the second coil pulling device 52, or the third coil pulling device 64 includes a pair of upper coil pulling rollers 641 and lower coil pulling rollers 642 that are rotatably arranged on the first frame 41, or the second frame 51, or the third frame 61 and are horizontally parallel to each other up and down. There is a worm and gear reduction motor three 643 fixed on the first frame 41, or the second frame 51, or the third frame 61, and the output end of which is connected to one end of the lower coil pulling roller 642. There is a pair of gear two 644 that are respectively fixed to one end of the upper coil pulling roller 641 and the lower coil pulling roller 642 and are meshed with each other. The two upper coil pulling rollers 641 and the lower coil pulling rollers 642 rotate synchronously and in opposite directions, and jointly clamp and pull the coil to move. By adopting the above-mentioned first coil pulling device 43, second coil pulling device 52, and third coil pulling device 64, when it is necessary to pull the coil, first, the worm and gear reduction motor three 643 will drive the lower coil pulling roller 642 to rotate. Then, the upper coil pulling roller 641 is driven to rotate in the opposite direction to the lower coil pulling roller 642 through the meshing transmission of a pair of gear two 644. Finally, the upper coil pulling roller 641 and the lower coil pulling roller 642 that are parallel to each other up and down will rotate relative to each other, and act on the upper and lower surfaces of the coil respectively. Furthermore, by using the friction between the roller surface and the surface of the coil, the coil is quickly pulled away from the coil drying tunnel furnace 1 or the coil vulcanization tunnel furnace 2.

[0051] As Figure 5 , Figure 9As shown in the figure, the coil cutting device 63 includes a cutting platform 631 fixed to the third frame 61, a pair of hydraulic cylinders II 632 fixed to the third frame 61, a cutting knife I 633 fixedly connected to the piston rod heads of the two hydraulic cylinders II 632, and a cutting groove 634 formed on the surface of the cutting platform 631 for the cutting knife I 633 to insert into. The cutting platform 631 is located between the downward pulling coil roller 642 and the coil guiding roller III 65, and the highest points of the downward pulling coil roller 642 and the coil guiding roller III 65 are flush with the upper surface of the cutting platform 631. By adopting the coil cutting device 63, when it is necessary to cut the finished coil, the hydraulic cylinder II 632 will extend its piston rod, causing the cutting knife at the piston rod head to move downward close to the cutting platform 631. After the cutting knife is inserted into the cutting groove 634 of the cutting platform 631, the coil passing through the surface of the cutting platform 631 can be cut, so as to cooperate with the reel 62 and the unloading trolley 66 to unload the finished coil of appropriate length; the reel 62 has a pair of horizontally parallel winding stations front and back, and the unloading trolley 66 is located below the two winding stations. The unloading trolley 66 includes a vehicle body II 661, a plurality of pairs of track wheels III 662 respectively rotatably arranged on both sides of the vehicle body II 661, a plurality of hydraulic cylinders III 663 installed inside the vehicle body II 661 with the piston rods extending out of the top of the vehicle body II 661, a lifting platform 664 fixed to the tops of all the hydraulic cylinders III 663, a material supporting platform II 665 slidably arranged on the lifting platform 664 and having a V-shaped top, a sliding assembly 666 for driving the material supporting platform II 665 to slide relative to the top of the lifting platform 664, a fan-shaped pushing plate 667 fixed to the top of the material supporting platform II 665. A power device for controlling the rotation of the track wheels III 662 is provided inside the vehicle body II 661, and two guide rails III 662a for each pair of track wheels III 662 to roll on are fixedly arranged on the ground; a pair of track wheels IV 665a are respectively rotatably installed at both ends of the material supporting platform II 665, and two guide rails IV 664a for the two pairs of track wheels IV 665a to roll on are fixedly arranged on the top of the lifting platform 664;

[0052] By adopting the above technical solution, when it is necessary to unload a finished coil of a certain length, first, the hydraulic cylinder II 632 extends its piston rod, so that the cutter head at the head of the piston rod moves downward close to the cutting platform 631. After the cutter is inserted into the cutting groove 634 of the cutting platform 631, the coil passing through the surface of the cutting platform 631 can be cut off. Then, the first station of the coiler 62 continues to wind the finished coil, so that it is all wound on this station. At the same time, the staff connects and places the subsequent finished coil on another station of the coiler 62, so as to quickly resume the winding task of the coiler 62, and then maintain the continuous operation of the equipment. Then, the sliding assembly 666 in the uncoiling trolley 66 drives the second material supporting table 665 to slide relative to the lifting platform 664. After the second material supporting table 665 moves to the position below the finished coil to be unloaded, the hydraulic cylinder III 663 in the uncoiling trolley 66 will extend its piston rod, so that the lifting platform 664 rises. At the same time, the second material supporting table 665 will support this finished coil when the lifting platform 664 rises. Finally, the coiler 62 releases the tension on the finished coil at this station, and the second vehicle body 661 in the uncoiling trolley 66 leaves below this station along the guide rail IV 664a, so that the second material supporting table 665 can cooperate with the pushing plate 667 to push out and unload this finished coil from the station of the coiler 62, thereby achieving the effect of automatic blanking of the finished coil.

[0053] As Figure 9As shown, the sliding component 666 includes a lead screw three 666a rotatably arranged on the lifting table 664, a servo motor three 666b fixed to the body of the lifting table 664 with its output end connected to one end of the lead screw three 666a, and a nut three 666c fixed to the bottom of the material supporting table two 665 and threadedly connected to the lead screw three 666a. A supporting plate three 665b is fixedly arranged at the bottom of the material supporting table two 665, and the lead screw three 666a movably passes through the supporting plate three 665b, and the nut three 666c is fixed to the supporting plate three 665b. At both ends of the lifting table 664 located on the guide rail four 664a, limiting plates 664b are vertically fixed respectively, and the height of the limiting plates 664b exceeds the height of the guide rail four 664a. The servo motor three 666b is fixed to the back of one limiting plate 664b, and one end of the lead screw three 666a rotatably passes through this limiting plate 664b and is connected to the output end of the servo motor three 666b. A pair of guide rods four 664c parallel to the lead screw three 666a are fixedly arranged between the two limiting plates 664b, and the guide rods four 664c movably pass through the supporting plate three 665b. By adopting the above technical solution, when it is necessary to control the movement of the material supporting table two 665 under the finished product coil to be unloaded, first, the servo motor three 666b drives the lead screw three 666a to rotate. Then, under the rotation of the lead screw three 666a, the nut three 666c drives the supporting plate three 665b to slide relative to the guide rod four 664c on the lifting table 664. Finally, the supporting plate three 665b drives the entire material supporting table two 665 to move along the guide rail four 664a, thereby achieving the effect that the uncoiling trolley 66 can unload materials from the two workstations of the coiling machine 62 respectively. Among them, the limiting plates 664b can effectively prevent the track wheels four 665a of the material supporting table two 665 from rolling off the two ends of the guide rail four 664a.

[0054] As Figure 3 , Figure 4 shown, it further includes a coil automatic welding mechanism 8. The coil automatic welding mechanism 8 includes a pair of movable welding tables 82 fixedly connected to the side of the moving platform 321 close to the first frame 41, a fixed welding table 81 fixedly connected to the side of the first frame 41 close to the moving platform 321, a pressing plate one 83 and a pressing plate two 84 respectively arranged on the tops of the fixed welding table 81 and the movable welding table 82 in a lifting manner, a hydraulic cylinder four 85 and a hydraulic cylinder five 86 respectively driving the pressing plate one 83 and the pressing plate two 84 to move up and down, a pair of turning plates one 87 and turning plates two 88 respectively arranged on both sides of the fixed welding table 81 in a turning manner, a turning device 89 respectively driving the turning plates one 87 and the turning plates two 88 to turn, a cutting knife two 8a fixed to one side of the turning plate one 87, a slider 8b slidably arranged on one side of the turning plate two 88, a sliding device 8c driving the slider 8b to slide relative to the turning plate two 88, and a welding torch 8d fixed to one side of the slider 8b.

[0055] The fixed welding table 81 and the first frame 41 are jointly connected with a pair of parallel connecting arms 811. A plurality of first conveying rollers 812 are rotatably arranged between the connecting arms 811. The movable welding table 82 and the moving platform 321 are jointly connected with a pair of parallel connecting arms 821. A plurality of second conveying rollers 822 are rotatably arranged between the connecting arms 821. At the bottom of the movable welding table 82, two pairs of fifth track wheels 823 are rotatably arranged, and on the ground, fifth guide rails 823a for each pair of fifth track wheels 823 to roll are fixedly arranged.

[0056] On the tops of the fixed welding table 81 and the movable welding table 82, an inverted U-shaped plate 813 and an inverted U-shaped plate 824 are respectively fixedly arranged. The fourth hydraulic cylinder 85 and the fifth hydraulic cylinder 86 are respectively fixed on the tops of the inverted U-shaped plate 813 and the inverted U-shaped plate 824. The first pressing plate 83 and the second pressing plate 84 respectively move up and down inside the inverted U-shaped plate 813 and the inverted U-shaped plate 824. On the tops of the first pressing plate 83 and the second pressing plate 84, a fifth guide rod 831 and a sixth guide rod 841 that movably pass through the top walls of the inverted U-shaped plate 813 and the inverted U-shaped plate 824 are respectively fixedly arranged. The piston rods of the fourth hydraulic cylinder 85 and the fifth hydraulic cylinder 86 respectively movably pass through the top walls of the inverted U-shaped plate 813 and the inverted U-shaped plate 824, and are respectively fixedly connected to the tops of the first pressing plate 83 and the second pressing plate 84.

[0057] One side of the movable welding table 82 and the fixed welding table 81 is close to each other. On this side of the movable welding table 82, a long strip convex platform 825 is fixedly arranged. On this side of the fixed welding table 81, a long strip edge groove 814 that is connected to the long strip convex platform 825 is provided. One ends of the first turning plate 87 and the second turning plate 88 are respectively hinged to the left and right sides of the inverted U-shaped plate 813. The first turning plate 87 and the second turning plate 88 jointly move in the gap between the inverted U-shaped plate 813 and the inverted U-shaped plate 824. When the first turning plate 87 turns and is parallel to the upper part of the fixed welding table 81, the second cutter 8a on the first turning plate 87 will cut the coil material. When the second turning plate 88 turns and is parallel to the upper part of the fixed welding table 81, the muzzle of the welding torch 8d on the second turning plate 88 is directly opposite to the upper surface of the coil material. A gap is left at the vertical connection of the long strip convex platform 825 and the long strip edge groove 814. When the second cutter 8a cuts the coil material, it can movably insert into this gap. When the welding torch 8d welds the coil material, it can be aligned with this gap and move along this gap under the drive of the slider 8b.

[0058] By adopting the above technical solution, when the old coil is about to finish unwinding, first, other mechanisms except the coil unwinding mechanism 3 and the coil automatic welding mechanism 8 of the present invention pause working. Then, the hydraulic cylinder four 85 on the fixed welding table 81 and the hydraulic cylinder five 86 on a movable welding table 82 will respectively extend the piston rods, causing the pressing plate one 83 and the pressing plate two 84 to descend and press the tail of the old coil. Then, a flipping device 89 drives the flipping plate one 87 on the fixed welding platform to flip, so that the cutting knife two 8a connected to the flipping plate one 87 flips from the above-mentioned gap to cut off the tail of the old coil. After cutting, the flipping device 89 will control the flipping plate one 87 to flip back to the initial position. Then, the moving platform 321 in the moving device 32 starts to move, aligning the station with the new coil and the coil inlet of the first frame 41. Since the movable welding platform is connected to the moving platform 321 through the connecting arm two 821, the movable welding platform carrying the part cut from the tail of the old coil will move together with the moving platform 321, and in this way, the part cut from the tail of the old coil is taken away from the fixed welding platform. Before that, the pressing plate two 84 on another movable welding platform will press the head of the new coil in advance before the above steps, and ensure that the front edge of the head of the new coil is aligned with the above-mentioned gap position. Therefore, after the moving platform 321 moves, this movable welding platform will press the head of the new coil close to the fixed welding table 81 until the front end of the head of the new coil is aligned with the rear end of the tail of the old coil carried on the fixed welding table 81. Finally, another flipping device 89 drives the flipping plate two 88 on the fixed welding platform to flip, so that the muzzle of the welding torch 8d on the flipping plate two 88 faces the gap between the front edge of the head of the new coil and the rear edge of the tail of the old coil. At the same time, the sliding device 8c on the flipping plate two 88 drives the slider 8b loaded with the welding torch 8d to slide, so that the muzzle of the welding torch 8d can move along the gap between the two for welding work, thereby achieving the effect of automatically welding and connecting the head of the new coil and the tail of the old coil in this way.

[0059] As Figure 4As shown in the figure, the flipping device 89 includes a second rotating shaft 891 rotatably arranged on the side wall of the inverted U-shaped plate 813, a second worm gear 892 fixed on the second rotating shaft 891, a second worm 893 rotatably arranged on the side wall of the inverted U-shaped plate 813 and meshing with the second worm gear 892, and a fourth servo motor 894 fixedly arranged on the side wall of the inverted U-shaped plate 813 with its output end connected to the second worm 893. A protective box 895 is fixedly arranged on the side wall of the inverted U-shaped plate 813, and the second rotating shaft 891 and the second worm 893 are rotatably arranged in the protective box 895. The fourth servo motor 894 is fixed on the top of the protective box 895. One end of the second worm 893 rotatably passes through the top wall of the protective box 895 and is fixedly connected to the output end of the fourth servo motor 894. The first flipping plate 87 or the second flipping plate 88 is located beside one end of the protective box 895. The second rotating shaft 891 rotatably passes through the end wall of the protective box 895 and is fixedly connected to one end of the first flipping plate 87 or the second flipping plate 88. By adopting the above flipping device 89, when it is necessary to control the flipping of the first flipping plate 87 or the second flipping plate 88, first, the fourth servo motor 894 drives the second worm 893 to rotate, so that the second worm 893 meshes with and drives the second worm gear 892. Then, the second worm gear 892 drives the second rotating shaft 891 to rotate. Finally, the second rotating shaft 891 drives the first flipping plate 87 or the second flipping plate 88 to perform a flipping motion centered on its axis. The protective box 895 can hide the second rotating shaft 891, the second worm gear 892 and the second worm 893, and protect the safe meshing and transmission of the first worm gear 538b and the first worm 538a.

[0060] As Figure 4 shown in the figure, the sliding device 8c includes a fourth lead screw 8c1 rotatably arranged on the second flipping plate 88, a fourth nut 8c2 fixed on the slider 8b and threadedly connected to the fourth lead screw 8c1, and a small motor 8c3 fixed on the second flipping plate 88 with its output end connected to one end of the fourth lead screw 8c1. A long slot 881 for the slider 8b to slide is formed on the second flipping plate 88. The fourth lead screw 8c1 is rotatably arranged in the long slot 881 and movably passes through the slider 8b. The small motor 8c3 is fixed at one end of the second flipping plate 88 away from its flipping center.
