Technical Field

[0001] This application relates to the technical field of automatic winding, and in particular to a fully automatic winding machine. Background Art

[0002] Low-temperature metal wound gaskets are high-performance gaskets widely used in industrial seals, which are formed by alternately winding metal strips and non-metallic filling materials. Their core feature is to achieve reliable sealing under harsh working conditions such as low temperature, high pressure, and strong corrosion through the elastic deformation of the metal strip and the sealing performance of the non-metallic filling material.

[0003] Existing low-temperature metal wound gaskets usually use a winding machine. Before winding, it is necessary for workers to preliminarily fix the steel strip, graphite strip, and metal inner ring through a spot welding mechanism, then install the metal inner ring on the winding machine, and perform cutting through structures such as blades after winding. The above-mentioned winding operation is relatively cumbersome and there are problems with winding accuracy. In view of the above situation, this application provides a fully automatic winding machine that can realize the automatic winding of metal wound gaskets. Summary of the Invention

The cooperation between the steel belt feeding roller and the steel belt fixing plate provides reliable support and guidance for the steel belt, ensuring the stability of the steel belt during conveying. The design of multiple first fixed pulleys and the lifting-mounted second fixed pulley can effectively adjust the tension of the steel belt to avoid looseness or jamming during conveying.

[0014] By adopting the above technical solution, the cooperation of the clamping driving part and the three-jaw chuck part can realize the stable clamping of the metal inner ring, ensuring the positioning accuracy of the metal inner ring during the winding process. The arrangement of the pressing wheel bracket, the first pressing wheel disc and the second pressing wheel disc can provide a stable pressing force during the winding process of the graphite tape and the steel tape, avoiding loosening or deviation, thereby improving the winding quality.

The design of the pushing gap enables the metal inner ring to be pushed one by one, avoiding jamming. The setting of the adjusting bolt in the strip hole can be adjusted according to metal inner rings of different sizes, improving the adaptability of the equipment.

[0035] Reference Figure 2 and Figure 3 The graphite belt feeding mechanism 2 is used for graphite belt feeding, and includes a graphite feeding base 21, a graphite feeding box 22 slidably mounted on the graphite feeding base 21, and a graphite conveying member 23 for driving the graphite belt conveying. The side wall of the fixed main frame 1 has an extended main frame 11 for the graphite feeding base 21 to be tilted and fixed, a graphite reversing plate 24 is fixed at the bottom of the graphite feeding box 22, a slide rail that slidably cooperates with the graphite reversing plate 24 is provided at the top of the graphite feeding base 21, and a pushing cylinder (not marked in the figure) for pushing the graphite reversing plate 24 is provided on one side of the graphite feeding base 21.

[0036] A graphite feeding roller 221 is installed in the graphite feeding box 22, and graphite baffles 222 are arranged at intervals in the axial direction of the graphite feeding roller 221.

[0038] The graphite conveying member 23 includes a graphite conveying fixed plate 231, a graphite conveying lifting plate 232 and a graphite conveying chain 233. The graphite conveying fixed plate 231 and the graphite feeding base 21 are arranged in parallel, and the graphite conveying fixed plate 231 has a first graphite channel 2311 for conveying the graphite belt, and the graphite conveying lifting plate 232 is installed on one side of the graphite conveying fixed plate 231 by cylinder lifting. A graphite pressure wheel 234 for conveying the graphite conveying chain 233 is installed on the graphite conveying lifting plate 232, wherein the graphite discharging track 241 is provided with a clearance insertion groove 2411 for the graphite pressure wheel 234 to be dropped and inserted at one end away from the friction wheel 223. An air blowing pipe 235 connected to an air source is also installed on the graphite conveying lifting plate 232. The output pipe of the air blowing pipe 235 faces the graphite discharging track 241, which is used to tilt the raised graphite ribbon downward so that the graphite pressure wheel 234 can be pressed on the top of the graphite ribbon, and then the graphite ribbon is conveyed through the graphite conveying chain 233.

[0039] Reference Figure 4, the steel strip loading mechanism 3 is entirely located below the graphite strip loading mechanism 2, and it includes a steel strip loading roller 31, a steel strip fixing plate 32, a first fixed pulley 33, and a second fixed pulley 34. The steel strip loading roller 31 is driven by a motor. The steel strip fixing plate 32 is vertically arranged on one side of the steel strip loading roller 31, and both the first fixed pulley 33 and the second fixed pulley 34 are installed on the steel strip fixing plate 32. In this embodiment, there are three groups of first fixed pulleys 33 and two groups of second fixed pulleys 34 arranged on the steel strip fixing plate 32. Among them, the two groups of second fixed pulleys 34 are both installed on a lifting plate, which is slidably installed on the steel strip fixing plate 32 and is lifted by a cylinder. The tensioning effect of the steel strip is achieved through the lifting of the second fixed pulley 34.

[0040] Two groups of forming pulleys 35 for steel strip conveying and corresponding friction pulleys 36 are also installed on the extended main frame 11. Through the two groups of forming pulleys 35 and friction pulleys 36, the conveying of the steel strip is switched from the vertical direction to the horizontal direction.

[0041] Combined with Figure 5 , the cutting mechanism 4 includes a first cutting driving member 41, a first blade 42, a second cutting driving member 43, and a second blade 44. A cutting bracket 12 for installing the cutting mechanism 4 is provided on the extended main frame 11. The cutting bracket 12 has a second graphite channel 121 and a first steel strip channel 122 for respectively conveying the graphite strip and the steel strip. The second graphite channel 121 and the first graphite channel 2311 are corresponding and arranged in parallel. Both the first cutting driving member 41 and the second cutting driving member 43 are cylinder parts. The two cutting driving members are staggered, and the pushing directions of the two piston rods are opposite.

[0042] The collecting mechanism 5 is rotatably installed on one side of the cutting mechanism 4 and is used to receive the graphite strip from the second graphite channel 121 and the steel strip from the first steel strip channel 122. In this embodiment, the collecting mechanism 5 is rotated by a cylinder. The collecting mechanism 5 has two sub-channels 51 respectively communicating with the second graphite channel 121 and the first steel strip channel 122 and a combined channel 52 that merges the two sub-channels 51.

[0043] During winding, first wind the steel strip around the metal inner ring for three turns, then wind the steel strip and the graphite strip simultaneously, and finally wind the steel strip alone for three more turns. Through the alternating winding of the steel strip and the graphite strip, the structural strength and sealing effect of the metal inner ring are ensured. Among them, when winding the graphite strip, the graphite conveying lifting plate 232 is in the raised state, that is, the graphite conveying chain 233 and the graphite strip are not in contact, and the graphite strip is wound through the rotation of the clamping mechanism 6.

[0044] Refer to Figure 6, the clamping mechanism 6 is used to clamp and rotate the metal inner ring, and its overall structure is the same as that of the three-jaw chuck of the processing machine tool. The clamping mechanism 6 includes a clamping driving part 61 and a three-jaw chuck part 62 connected to the clamping driving part 61. The clamping driving part 61 includes two driving parts, and the two driving parts are used to respectively control the clamping and rotation of the three-jaw chuck part 62.

[0045] To improve the stability of winding, a pressing wheel mechanism 63 is also installed above the clamping mechanism 6 on the fixed main frame 1. The pressing wheel mechanism 63 includes a pressing wheel bracket 631, a first pressing wheel disc 632, and a blanking pushing plate 633. The pressing wheel bracket 631 realizes sliding in the height direction through a cylinder, and the first pressing wheel disc 632 is rotatably installed on the pressing wheel bracket 631 through a rotary bearing. The first pressing wheel disc 632 and the chuck of the three-jaw chuck are correspondingly arranged, so that when the first pressing wheel disc 632 descends, the first pressing wheel disc 632 can be pressed tightly on the metal inner ring, and as the graphite tape and the steel tape are wound, the outer diameter of the metal inner ring gradually increases, and the first pressing wheel disc 632 gradually rises under the action of the cylinder as the outer diameter of the metal inner ring increases, ensuring that the first pressing wheel disc 632 always abuts against the outer side of the metal inner ring.

[0046] A second pressing wheel disc 634 that abuts against the metal inner ring is also slidably installed on the fixed main frame 1, and the second pressing wheel disc 634 slides horizontally through a cylinder.

[0047] The blanking pushing plate 633 is slidably installed on the fixed main frame 1, and the blanking pushing plate 633 realizes horizontal movement through a cylinder. One end of the blanking pushing plate 633 corresponds to the metal inner ring. When the winding of the metal inner ring is completed, the clamping mechanism 6 releases the clamping, and then the cylinder drives the blanking pushing plate 633, so that the metal inner ring disengages from the three-jaw chuck part 62.

[0048] The spot welding mechanism 7 is installed below the clamping mechanism 6 through a cylinder for lifting and lowering, and spot welding is performed on the steel tape or the graphite tape through the spot welding mechanism 7 before each winding to ensure the stability during winding. The spot welding part of the spot welding mechanism 7 is a spot welding disc.

[0049] Refer to Figure 7 and Figure 8 , the inner ring feeding mechanism 8 includes a feeding platform 81, a positioning component 82, a feeding pushing plate 83, and a feeding manipulator 84. The feeding platform 81 is located on one side of the fixed main frame 1. The positioning component 82 is installed on the top of the feeding platform 81, and a plurality of stacked metal inner rings are arranged on the positioning component 82. The positioning component 82 includes a fixed V-shaped plate 821 and a folded plate 822 arranged on the opening side of the fixed V-shaped plate 821. There is a pushing gap between the bottom of the fixed V-shaped plate 821 and the feeding platform 81 for pushing a single metal inner ring.

[0050] The folded plate 822 is integrally an L-shaped plate. There are also two groups of positioning rods 823 fixed on one side of the folded plate 822 close to the fixed V-shaped plate 821. The metal inner rings are stacked and arranged between the fixed V-shaped plate 821 and the positioning rods 823. On the loading platform 81, there is a fixed plate 811 for installing the folded plate 822. Along the conveying direction of the metal inner rings, a plurality of screw holes are spaced apart on the fixed plate 811. The folded plate 822 has strip-shaped holes corresponding to the plurality of screw holes, and adjusting bolts cooperating with the screw holes are installed at the strip-shaped holes of the folded plate 822, so that the folded plate 822 can be adjusted back and forth on the fixed plate 811 according to the outer diameter of the metal inner rings.

[0051] The loading push plate 83 is slidably arranged on the loading platform 81 through a cylinder. The thickness of the loading push plate 83 is adapted to the pushing gap, so that the loading push plate 83 can push a single metal inner ring out of the positioning assembly 82. Wherein, the end of the loading push plate 83 also has a V-shaped groove 831 to ensure the stability when pushing the metal inner ring.

[0052] Referring to Figure 7 and Figure 9 , the loading manipulator 84 is used to load the metal inner rings onto the three-jaw chuck member 62. It includes a first moving module 841, a loading push cylinder 842 arranged on the first moving module 841, a clamping cylinder 843, and a clamping manipulator 844. The first moving module 841 is a linear module in the prior art and is fixed above the positioning assembly 82 through a bracket. The moving direction of the first moving module 841 is perpendicular to the conveying direction of the metal inner rings.

[0053] The end of the loading push cylinder 842 is installed with a loading cylinder plate 8421, and the loading cylinder plate 8421 is rotationally matched with the slider of the first moving module 841. A rotation driving member 845 for driving the loading cylinder plate 8421 to rotate is installed on the first moving module 841, and the rotation driving member 845 is a push cylinder.

[0054] The clamping cylinder 843 is fixed to the output end of the loading push cylinder 842. The clamping manipulator 844 is fixed to the output end of the clamping cylinder 843. It includes a clamping fixed plate 8441 and a clamping head 8442 slidably installed on the clamping fixed plate 8441. After the clamping driving member 61 is started, it can drive the two clamping fixed plates 8441 to move towards each other or away from each other, and the clamping or loosening of the metal inner rings is realized through the clamping head 8442.

[0055] Referring to Figure 10, the blanking mechanism 9 is used to blank the wound metal inner ring, and it includes a second moving module 91, a blanking bracket 92, a blanking plate 93 and a blanking driving member 94. The second moving module 91 is arranged on the top of the fixed main frame 1, and its structure and principle are the same as those of the first moving module 841. The driving direction of the second moving module 91 is perpendicular to that of the first moving module 841. The blanking bracket 92 is installed on the slider of the second moving module 91 through a cylinder for lifting and lowering.

[0056] The blanking driving member 94 includes a first blanking cylinder 941 vertically fixed to the blanking bracket 92 and a second blanking cylinder 942 horizontally fixed to the output end of the first blanking cylinder 941, and the blanking plate 93. A blanking positioning column 931 for the metal inner ring to be sleeved is installed on the blanking plate 93.

[0057] In order to facilitate the blanking and collection of the metal inner ring, a blanking collection rack 95 is also installed on the other side of the fixed main frame 1. The blanking collection rack 95 includes a blanking fixing plate 951 and a blanking main rod 952 rotatably installed on the blanking fixing plate 951, and the blanking main rod 952 is rotated by a motor. Two groups of blanking sub-rods 953 are installed on the top of the blanking main rod 952, and both groups of blanking sub-rods 953 include two sub-rods. A detection sensor for detecting the metal inner ring is installed on the blanking collection rack 95. According to the detection result, one sub-rod is used for sleeving the qualified wound metal inner ring, and the other sub-rod is used for sleeving the unqualified wound metal inner ring. When the number of metal inner rings on one of the groups of sub-rods reaches the maximum number, the blanking main rod 952 is rotated to turn the blanking sub-rod 953 filled with metal inner rings towards the operator side, and the metal inner rings are manually removed.

[0058] The implementation principle of an automatic winding machine in an embodiment of the present application is as follows: The graphite tape feeding mechanism 2, the steel tape feeding mechanism 3 and the inner ring feeding mechanism 8 are started simultaneously, so that the metal inner ring is fed and fixed under the action of the clamping mechanism 6; First, wind the steel tape alone for three turns, and then the graphite conveyor 23 drives the graphite tape to move, so that the graphite tape and the steel tape converge, and the steel tape and the graphite tape are wound simultaneously. After winding the set number of turns, the graphite tape is cut off by the cutting mechanism 4, and finally the steel tape is wound alone for three turns, and the steel tape is cut off by the cutting mechanism 4.

[0059] After that, the wound metal inner ring is blanked to the blanking collection rack 95 through the blanking mechanism 9.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
