Description

Technical Field

[0001] The invention relates to the field of sealing ring processing equipment, and in particular to an automatic feeding device for the production and processing of sealing rings. Background Art

[0002] As a material to fill and seal the gaps between objects, sealing rings are widely used in the fields of construction, automobiles, electronic equipment, medical equipment and food packaging. During use, sealing rings can prevent dust, water, air and noise, and can effectively prevent the leakage of liquids, gases and dust, ensuring the normal operation of equipment and structures. Sealing rings are generally O-shaped strips, and are divided into different calibers according to the needs of the equipment. In order to ensure the production quality of sealing rings and reduce production costs during production and processing, hot pressing and vulcanization molding is mainly used in molding machines; For small-diameter sealing rings, the rubber strips are placed on multiple mold grooves side by side. After hot pressing with a molding machine, the rubber strips automatically melt and fill the mold grooves to form an integrated unit, which is not easy to be damaged or broken. When producing large-diameter sealing rings, due to the large diameter of the mold grooves, placing the rubber strips in a straight line can easily cause insufficient filling of the mold grooves, resulting in many defective products and waste of materials. In order to save materials, it is necessary to place the rubber strips in a ring state with the same diameter as the mold groove according to the diameter of the sealing ring mold groove, and then place them in the mold groove for hot pressing. In order to improve production efficiency, the existing feeding equipment has replaced the manual swing strips in the production of small-diameter sealing rings, which can automatically place the rubber strips on top of multiple mold grooves. However, in the automated production of large-diameter sealing rings, the splicing method is generally used for production and processing. Although it is not limited by length, gaps are prone to appear at the joints of the spliced ​​sealing rings, resulting in poor sealing effect, and the elasticity and ductility of the splicing are poor, which is easy to be damaged and broken. The production efficiency is low when the manual swing strips are hot-pressed. Summary of the invention

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0033] like Figure 1-16As shown, the present invention provides an automatic feeding device for the production and processing of sealing rings, including a base 1 and a mounting frame 2 fixedly connected to the upper end of the base 1, a molding machine for processing sealing rings is arranged on the right side of the base 1, and the molding machine is in an open state when feeding to the molding machine, and the annular mold groove provided on the surface of the molding machine is exposed to the outside, and a winding wheel 3 for winding a sealing strip is rotatably connected to the left end of the lower end of the mounting frame 2, and a support plate 9 capable of moving up and down is slidably connected to the right end of the mounting frame 2, and a side plate 11 is fixedly connected to the inner side of the right end of the mounting frame 2, and mounting grooves are provided on the surfaces of the side plates 11 in the height direction, and the upper ends of the support plates 9 are fixedly connected to mounting slide blocks, and the mounting slide blocks are slidably connected to the mounting slide blocks, so that the support plates 9 can move up and down stably, and the lower ends of the mounting slide blocks are fixedly connected to support springs 10, and the lower ends of the support springs 10 are fixedly connected to the lower ends of the inner ends of the mounting slide blocks, and the support springs 10 are fixedly connected to the lower ends of the inner ends of the mounting slide blocks. The spring 10 is used to support the support plate 9; the lower end of the support plate 9 is slidably connected to a mobile frame 5 that can move left and right, and the lower end of the front support plate 9 is fixedly connected to an electric push rod 4, and the retractable end of the electric push rod 4 is fixedly connected to the mobile frame 5. When the support plate 9 moves up and down, the mobile frame 5 can be driven to move up and down synchronously, and the mobile frame 5 can be driven to move left and right by controlling the extension and contraction of the electric push rod 4, so that the mobile frame 5 can move up and down as well as left and right; the right end of the mobile frame 5 is fixedly connected to a ring-shaped discharging device, and the rear end of the mobile frame 5 is provided with a plurality of clamps that are arranged side by side and connected to each other along the length direction of the mobile frame 5. Driven by the support plate 9, the plurality of clamps can be synchronously moved downward to clamp the sealing strip, the leftmost clamp is slidably connected to the mobile frame 5, and the rightmost clamp is connected to the ring-shaped discharging device, and when the ring-shaped arrangement device rotates, the plurality of clamps can be driven to move and be arranged in a ring state; When the device is in use, the winding wheel 3 is used to wind the rubber strip for processing the sealing ring, which is convenient for subsequent sealing ring processing. The sealing ring rubber strip extends to the lower side of multiple clamps. When processing the sealing ring, the support plate 9 can be controlled to move downward to drive the moving frame 5 to move downward. When the moving frame 5 moves downward, the clamp can contact the rubber strip and clamp the rubber strip. Then, the multiple clamps are driven by the annular arrangement device to move to the right and are arranged in sequence in an annular state, and then the rubber strip clamped by the clamp is also changed from a vertical state to an annular state. In order to facilitate the cutting, a cutter 76 is installed at the lower end of the leftmost clamp, and a stopper 57 is provided on one side of the rightmost clamp. The stopper 57 is fixedly connected to the base 1. In the process of multiple clamps being arranged in a ring, the leftmost clamp moves to the rightmost end. When the cutter 76 contacts the stopper 57, a reaction force is generated to move the cutter 76 in the direction of the sealing rubber strip to cut the sealing rubber strip. The cut rubber strip is in a ring state under the clamping of the clamp, and then the movable frame 5 is controlled to move in the direction of the molding machine so that the rubber strip in the ring state is located above the mold groove, and then the movable frame 5 is controlled to move downward, and the clamp is controlled to loosen so that the rubber strip in the ring state is placed in the mold groove. After the movable frame 5 is reset, the molding machine can be controlled to close to process the rubber strip into a sealing ring. When the rubber strip is clamped by the clamp, a new rubber strip appears in its original position after the rubber strip clamped by the clamp is cut off. Then, when the movable frame 5 moves to the left and resets, it can move downward again to clamp the new rubber strip for processing. This cycle is repeated, and the rubber strip is automatically transformed into an annular state and fed upward in the direction of the molding machine. This greatly improves the efficiency of processing large-diameter sealing rings and avoids the current practice of manually placing the rubber strip into an annular state and placing it in the mold groove when processing large-diameter sealing rings. This has a high degree of automation, fully saves manpower, and saves processing costs. It also has high processing efficiency and large output, and is suitable for mass production.

[0034] Furthermore, in order to improve the stability of the rubber strip after being pulled out, the lower side of the clamp is respectively provided with support wheels 62 which are staggered with the clamp, and the support wheels 62 are respectively rotatably connected to the base 1, and the support wheels 62 are respectively arranged at the same height and distributed side by side, and the pulled out rubber strip is placed on the upper side of the support wheels 62 and supported by the support wheels 62. The circumferential surfaces of the support wheels 62 are respectively provided with annular grooves for limiting the rubber strip and preventing the rubber strip from detaching from the support wheels 62, and the support wheels 62 are staggered with the clamp, and each clamp is respectively located above the gap formed between every two support wheels 62. When the clamp moves downward to clamp the rubber strip, it will not touch the support wheels 62, so that the clamp can clamp the rubber strip conveniently.

[0035] Furthermore, the clamp includes a plurality of mounting plates 55 arranged side by side, and adjacent mounting plates 55 are interconnected and have adjustable spacing. The rear ends of the mounting plates 55 are respectively fixedly connected with vertically arranged conduction tubes 56, and the lower ends of the conduction tubes 56 are respectively hinged to two relatively arranged clamping plates 58. When the clamp moves downward, the rubber strip is located between the two clamping plates 58, and the lower end of the conduction tube 56 is slidably connected to a piston push rod 61 that can move up and down. The corresponding ends of the two clamping plates 58 are respectively hinged with connecting rods 60, and the other ends of the connecting rods 60 are hinged to the bottom of the piston push rod 61. The clamps 58 are controlled by the piston push rod 61, and when in use, the piston push rod 61 can be controlled to move upward. When the piston push rod 61 moves upward, the corresponding two clamping plates 58 can be driven to move inward synchronously through the linkage of the connecting rod 60, thereby clamping and fixing the rubber strip on the inside.

[0036] Furthermore, in order to facilitate the cooperation between the cutter 76 and the stopper 57 to cut the rubber strip at a fixed position during the movement of the clamp, as shown in FIG. Fig.14 As shown, the surfaces of the front and rear side clamps 58 at the lower end of the leftmost clamp are respectively fixedly connected with a pad 79 and a fixed block 73 in sequence. The fixed block 73 is used to install a cutter 76, and the pad 79 is used to cooperate with the cutter 76 to cut the rubber strip. The upper and lower sides of the fixed block 73 are respectively provided with a first spring groove with holes at both ends. The interior of the first spring groove is respectively provided with a second return spring 78, and the second return spring 78 is used to push the cutter 76 to return. The inner side of the second return spring 78 is respectively provided with a moving rod 75, and the moving rod 75 is respectively slidably connected to the openings at both ends of the first spring groove. The surface of the moving rod 75 located in the first spring groove is fixedly connected with a spring baffle 77, and the spring baffle 77 is slidably matched with the inner wall of the first spring groove. The second return spring 78 is respectively located on the front side of the spring baffle 77, and the cutter 76 is fixedly connected to the front end of the moving rod 75, and the rear ends of the two moving rods 75 are fixedly connected with a The first matching block 74 that matches with the stop block 57 has the left and right side surfaces of the rear end of the first matching block 74 tilted inwardly respectively, and the end of the stop block 57 facing the clamp is also tilted inwardly. When the clamp moves to the right, when the first matching block 74 contacts the stop block 57, the reaction force generated by the mutual fit and pressure of the inclined surface at one end of the stop block 57 and the inclined surface at the rear end of the first matching block 74 can push the moving rod 75 to move in the direction of the rubber strip. When the moving rod 75 moves, the second return spring 78 can be squeezed by the spring baffle 77, and the cutter 76 can be pushed to move in the direction of the rubber strip, pressing the rubber strip against the pad 79 to cut the rubber strip. When the first matching block 74 is separated from the stop block 57, the moving rod 75 is reset under the push of the second return spring 78, and then the cutter 76 is reset. After the rubber strip is cut off, it is still in a state of being clamped by the clamp, and then it is converted into a ring state under the action of the ring arrangement device for loading.

[0037] Further, such as Figure 3 and Figure 4 As shown, the annular discharging device includes a mounting ring 6 fixedly connected to the right side of the moving frame 5, a fixing plate 7 is coaxially arranged on the upper side of the mounting ring 6, a fixing tube 8 is fixedly connected between the mounting ring 6 and the fixing plate 7, a rotating plate 12 is rotatably connected to the inner side of the mounting ring 6, the rotating plate 12 is rotatably connected to the fixing tube 8 coaxially, a plurality of moving blocks 13 distributed in an annular shape are installed on the upper end of the rotating plate 12, the front end of the rightmost mounting plate 55 is hinged to the corresponding moving block 13, the front end of the mounting plate 55 is rotatably connected to the matching wheel 63, the matching wheel 63 and the surface of the moving block 13 Surface contact, a driving device for driving the rotating plate 12 to rotate is installed at the lower end of the mounting ring 6. The rotating plate 12 is controlled to rotate under the drive of the driving device. When the rotating plate 12 rotates, it can drive multiple moving blocks 13 to rotate along with the rotating plate 12, and when rotating, it drives multiple mounting plates 55 to surround the outside of multiple moving blocks 13 in a ring shape through the connection with the mounting plate 55 on the right side, thereby driving multiple clamps to move to a ring state, and when the mounting plate 55 is moving, the cooperating wheel 63 can maintain the ring-shaped distribution state by pressing the moving block 13 and maintain stability.

[0038] Furthermore, in order to process a sealing ring with a larger diameter and improve the application range of the device, the upper end of the rotating plate 12 is respectively provided with a plurality of evenly distributed adjustment slots in the radial direction, and the lower end of the moving block 13 is respectively fixedly connected with an adjustment slider, and the adjustment slider is respectively slidably connected with the adjustment slot, and the surface of the fixed tube 8 is slidably sleeved with a lifting plate 15 that can move up and down, and the lifting plate 15 is located on the upper side of the moving block 13, and the inner end of the moving block 13 is respectively hinged with a push rod 14, and the other end of the push rod 14 is respectively hinged with the lifting plate 15; The upper end of the lifting plate 15 is rotatably connected to a connecting plate 16, and the surface of the connecting plate 16 is rotatably connected to an adjusting screw 18, and the surface of the adjusting screw 18 is threadedly connected to a threaded barrel 17, and the upper end of the threaded barrel 17 is fixedly connected to the fixed plate 7, and the lower side of the surface of the adjusting screw 18 is fixedly connected to an adjusting knob 19, and the adjusting screw 18 can be driven to rotate by rotating the adjusting knob 19. Since the threaded barrel 17 is fixedly connected to the fixed plate 7, the threaded barrel 17 cannot be rotated. When the adjusting screw 18 rotates, it can drive the lifting plate 15 to move downward under the action of the threaded connection with the threaded barrel 17. When the lifting plate 15 moves downward, the push rod 14 When pushed, multiple moving blocks 13 can be pushed to move outward synchronously. When multiple mounting plates 55 are distributed in a ring shape under the rotation of the rotating plate 12, since the spacing between adjacent mounting plates 55 can be adjusted, when multiple moving blocks 13 move outward, the diameter of the ring state formed by the multiple mounting plates 55 can be increased, thereby increasing the spacing between the mounting plates 55. When the spacing between the multiple mounting plates 55 is increased, the overall length will become longer, so that longer rubber strips can be clamped. When the ring structure is formed, the diameter is increased, and a larger caliber sealing ring can be processed. When in use, it can be adjusted by turning the adjustment knob 19, which is convenient for users.

[0039] Furthermore, in order to facilitate the adjustment of the distance between two adjacent mounting plates 55, as shown in FIG. Fig.12 and Fig.13 As shown, one end corresponding to the adjacent mounting plates 55 is respectively fixedly connected with an extension plate 64, and a docking plate 65 is arranged on the upper side of two adjacent extension plates 64. The docking plate 65 is used to connect the two adjacent mounting plates 55. The inner ends of the two adjacent extension plates 64 are respectively rotatably connected with docking sliders, and docking grooves are respectively provided on both sides of the lower ends of the corresponding docking plates 65. The docking sliders are respectively slidably connected with the docking grooves, and the outer sides of the docking sliders are respectively fixedly connected with adjustment springs 69, and the other ends of the adjustment springs 69 are respectively fixedly connected with the docking grooves, and the adjustment springs 69 are used to push the mounting plates 55 on both sides to reset; The upper ends of the docking sliders are respectively fixedly connected with sliding rods, and the surfaces of the sliding rods are respectively axially slidably connected with reinforcing cylinders 70, and reinforcing springs 72 are respectively fixedly connected between the reinforcing cylinders 70 and the sliding rods. The corresponding two sides of the surface of the reinforcing cylinders 70 are respectively fixedly connected with reinforcing plates 71, and the reinforcing plates 71 are respectively located at the upper ends of the docking plates 65. When in use, the pressure of the reinforcing cylinders 70 is increased, thereby increasing the friction between the reinforcing plates 71 and the docking plates 65, so that the extension plate 64 and the docking plate 65 are fixed, thereby achieving the effect of maintaining the spacing between the mounting plates 55 on both sides. On the contrary, by canceling the reinforcing cylinders The pressure of 70 reduces the friction between the reinforcing plate 71 and the docking plate 65, so that the spacing between adjacent mounting plates 55 can be adjusted; further, in order to facilitate the fixation after adjusting the spacing between adjacent mounting plates 55, a pressing plate 66 is provided on the upper side of the docking plate 65, and a sliding groove is provided at the bottom of the pressing plate 66 along the length direction. The reinforcing cylinder 70 is slidably connected to the sliding groove, so that the reinforcing cylinder 70 can not only move inside the sliding groove, but also limit the pressing plate 66 under the action of the reinforcing cylinder 70, so that the pressing plate 66 can only move up and down, and the middle of the pressing plate 66 is threaded A reinforcing bolt 67 is connected, and the bottom of the reinforcing bolt 67 is rotatably connected to the corresponding docking plate 65. When adjusting the spacing between the mounting plates 55, the reinforcing cylinder 70 can slide inside the slide groove without affecting the movement of the mounting plate 55. When positioning is required, the reinforcing bolt 67 can be rotated. When the reinforcing bolt 67 rotates, the pressure plate 66 is threadedly connected to the pressure plate 66 to move downward to press the reinforcing cylinder 70. When the reinforcing cylinder 70 moves downward, it can drive the reinforcing plate 71 to move downward, and while squeezing the reinforcing spring 72, the space between the reinforcing plate 71 and the docking plate 65 is increased. The friction force is thereby achieved, thereby fixing the docking slider and the docking plate 65, making it impossible for the mounting plate 55 to move. Moreover, since the extension plate 64 and the docking slider are in a rotationally connected relationship, the swing of the extension plate 64 is not affected when the docking slider and the docking plate 65 are fixed. Reverse rotation of the reinforcing bolt 67 can drive the pressure plate 66 to move upward, and then the reinforcing cylinder 70 is pushed upward under the push of the reinforcing spring 72, so that the friction force between the reinforcing plate 71 and the docking plate 65 is reduced, and the extension plate 64 can slide at the lower end of the docking plate 65, making it convenient to adjust the spacing between adjacent mounting plates 55.

[0040] Furthermore, in order to facilitate the control of the clamp to clamp the rubber strip, a pressure cylinder 43 is fixedly connected to one side of the upper end of the fixed plate 7, and a gas control piston 44 that can move up and down is slidably connected inside the pressure cylinder 43.

A control plate 47 is arranged on the front side of the pressure cylinder 43. The control plate 47 is rotatably connected to the fixed plate 7. A hinged rod 46 is hinged at a non-center position of the control plate 47. The other end of the hinged rod 46 is hinged to the movable plate 45. When the control plate 47 rotates, the movable plate 45 can be driven to move up and down. When the movable plate 45 moves up and down, the gas control piston 44 can be driven to move up and down, thereby realizing air extraction and air injection. The upper ends of the conducting tubes 56 are respectively fixedly connected and connected with air guide tubes 68, and the other ends of the air guide tubes 68 are respectively fixedly connected and connected with the upper ends of the air pressure cylinders 43. When the air control piston 44 moves downward, the gas inside the conducting tube 56 can be sucked into the air pressure cylinder 43 through the air guide tube 68, thereby generating negative pressure suction to control the piston push rod 61 to move upward. When the piston push rod 61 moves upward, the clamping plates 58 on both sides can be driven to swing inward under the linkage of the linkage rod 60 to clamp the rubber strip; when the air control piston 44 moves upward, the gas inside the air pressure cylinder 43 can be pushed into the conducting tube 56 through the air guide tube 68, thereby pushing the piston push rod 61 to move downward, and then pushing the clamping plates 58 on both sides to swing outward under the linkage of the linkage rod 60 to achieve the effect of loosening the rubber strip; Furthermore, in order to improve the stability and firmness of the control splint 58 when clamping the rubber strip, a connecting rod 49 is fixedly connected to the middle part of the control plate 47, and the connecting rod 49 is rotatably connected to the upper end of the fixed plate 7.

When the stop tooth block 50 is meshed with the stop groove 54, the plane of the stop block is matched with the plane of the stop groove 54, so that the stop tooth block 50 can be fully limited by the connecting rod 49, so that the control plate 47 cannot rotate, and the surface of the stop tooth block 50 is rotatably connected with a pulley 53; the bottom of the stop tooth block 50 is opened upward A connecting hole is provided, and a matching rod 51 is axially slidably connected inside the connecting hole. A plurality of limiting protrusions are respectively opened on the circumferential surface of the matching rod 51 along the axial direction, and a plurality of limiting grooves are respectively opened on the inner wall of the connecting hole along the axial direction. The limiting protrusions are respectively slidably matched with the limiting grooves, so that the stop tooth block 50 can only move axially. The bottom of the matching rod 51 is fixedly connected to the fixing plate 7, and a first return spring 52 is provided on the upper end of the matching rod 51. The first return spring 52 is used to push the stop tooth block 50 to move upward. When the stop tooth block 50 is engaged with the stop groove 54, the connecting rod 49 cannot rotate, and then the control plate 47 cannot rotate, and then the splint 58 cannot swing. By pushing the pulley 53 downward, the stop tooth block 50 can be driven to move downward and squeeze the first return spring 52, and the stop tooth block 50 is disengaged from the stop groove 54, and the control plate 47 can resume rotation and drive the splint 58 to open and close.

[0041] In order to further improve the linkage between the mobile frame 5 and the clamp, the clamp can automatically open the rubber strip after the mobile frame 5 moves downward, and the mobile frame 5 automatically moves upward after the clamp clamps the rubber strip, so as to facilitate the movement of the mobile frame 5. A rotating cylinder 29 is rotatably connected to the middle part of the upper end of the fixed plate 7. A guide cylinder 30 is arranged on the inner side of the rotating cylinder 29. The guide cylinder 30 is fixedly connected to the mobile frame 5. A guide groove 31 is arranged on the surface of the guide cylinder 30. The guide groove 31 is in a wavy structure and has two highest points and two lowest points. The rotating cylinder 29 is cross-distributed between the highest point and the lowest point, and the two corresponding sides on the upper side of the surface of the rotating cylinder 29 are respectively fixedly connected with guide pins 32, and the inner ends of the guide pins 32 are respectively engaged with the guide grooves 31. When the two guide pins 32 on the upper side of the movable frame 5 are respectively engaged with the two highest points of the guide grooves 31, the rotating cylinder 29 can move up and down while rotating under the sliding cooperation between the guide pins 32 and the guide grooves 31, and the structure is formed that when the rotating cylinder 29 rotates 90 degrees, it is located at the lower side, and when it rotates another 90 degrees, it is located at the upper side; A fixing ring 33 is fixedly connected to the lower side of the surface of the rotating cylinder 29, and a shift plate 34 is fixedly connected to the circumferential surface of the fixing ring 33. A driving ring 35 is arranged on the outer side of the fixing ring 33, and the driving ring 35 is rotatably connected to the upper end of the fixing plate 7. Bevel gear blocks 37 are fixedly connected to the corresponding two sides of the upper end of the driving ring 35, and the two bevel gear blocks 37 are spaced 180 degrees apart. The lower sides of the bevel gear blocks 37 are coaxially fixedly connected with arc-shaped push plates 59, and the two ends of the arc-shaped push plates 59 are provided with arc surface structures, and the bevel gear block 37 is protruded at one end close to the driven bevel gear 48, which is used to squeeze the pulley 53 downward before the bevel gear block 37 is engaged with the driven bevel gear 48; a driven bevel gear 48 that can mesh with the bevel gear block 37 is fixedly connected to the surface of the connecting rod 49, and one of the bevel gear blocks 37 is close to the driven bevel gear 48. A tension spring 36 is fixedly connected to the upper end of the fixing tube 8 and the driving ring 35; A locking ring 38 is provided between the fixing ring 33 and the driving ring 35. The locking ring 38 is fixedly connected to the fixing plate 7. Four locking grooves 39 are evenly provided on the circumferential surface of the locking ring 38. Adjacent locking grooves 39 are spaced ninety degrees apart. A locking tooth block 41 is radially slidably connected to the inner side of the driving ring 35. The outer end of the locking tooth block 41 meshes with the corresponding locking groove 39. An engagement spring 40 is fixedly connected to the end of the locking tooth away from the locking groove 39. The other end of the engagement spring 40 is fixedly connected to the locking ring 38. The engagement spring 40 is used to push the locking tooth block 41 to mesh with the locking groove 39. When the locking tooth block 41 meshes with the locking groove 39, the driving ring 35 cannot rotate. Therefore, when the rotating cylinder 29 drives the fixing ring 33 to rotate, the tension spring 36 is in a process of continuous stretching. A triangular block 42 is fixedly connected to the upper end of the locking tooth block 41. When the fixing ring 33 rotates with the rotating cylinder 29, the triangular block 42 is pushed by the shift plate 34 to make the locking tooth block 41 disengage from the locking groove 39. When the rotating cylinder 29 rotates ninety degrees, it moves downward, thereby driving the moving frame 5 to move downward as a whole, so that the clamp moves downward, and when the rotating cylinder 29 rotates ninety degrees, the shift plate 34 contacts and pushes the triangular block 42 to make the locking tooth block 41 disengage from the locking groove 39. After the locking tooth block 41 disengages from the locking groove 39, the driving ring 35 can rotate ninety degrees under the pull of the tension spring 36, and drive the bevel tooth block close to the driven bevel gear 48. The bevel gear block 37 moves and meshes with the driven bevel gear 48. When the bevel gear block 37 and the driven bevel gear 48 mesh, the arc push plate 59 will first contact with the pulley 53 and press the pulley 53 downward, so that the stop gear block 50 is disengaged from the stop groove 54, and then the bevel gear block 37 and the driven bevel gear 48 are meshed, driving the driven bevel gear 48 to rotate. After the driving ring 35 rotates ninety degrees, the locking gear block 41 is pushed by the meshing spring 40 to mesh with the new locking groove 39 again, and after the bevel gear block 37 and the driven bevel gear 48 are disengaged, the arc push plate 59 is disconnected from the pulley 53, and the stop gear block 50 is reset to mesh with the stop groove 54 again, so as to limit the control plate 47. Whenever the bevel gear block 37 and the driven bevel gear 48 are meshed, the driven bevel gear 48 can be driven to rotate 180 degrees. When the driven bevel gear 48 rotates, the control plate 47 can be driven to rotate 180 degrees, thereby driving the moving plate 45 to move downward, so that the piston push rod 61 moves upward and drives the clamping plate 58 to clamp the rubber strip inside. Then, the rotating cylinder 29 continues to rotate 90 degrees, and while the tension spring 36 is stretched, the moving frame 5 is driven to move upward. At the same time, the clamp clamps the rubber strip and moves upward synchronously. Then, during the rotation of the rotating plate 12, The middle driving clamp is arranged in a ring state, and the cutter 76 moves to cut the rubber strip under the pressure of the stopper 57; and when the rotating cylinder 29 continues to rotate 90 degrees, the paddle 34 can still push the locking tooth block 41 out of the locking groove 39, thereby driving the driving ring 35 to rotate, but because the two bevel tooth blocks 37 are correspondingly arranged with a spacing of 180 degrees between them, it will not affect the clamp, but it will shorten the spacing of the bevel tooth block 37 away from the driven bevel gear 48 by 90 degrees, so as to get close to the driven bevel gear 48, so as to meet the requirement of meshing next time; Only when the movable frame 5 moves toward the molding machine to feed the material, the rotating cylinder 29 continues to rotate ninety degrees to drive the movable frame 5 to move downward, so that the clamp corresponds to the mold groove on the surface of the molding machine, and then the triangular block 42 can be pushed by the dial plate 34 to disengage the locking tooth block 41 from the locking groove 39, so that the driving ring 35 rotates under the traction of the tension spring 36, driving the bevel gear block close to the driven bevel gear 48 to engage with the driven bevel gear 48, driving the clamp plate 58 to open outward and release the rubber strip.

[0042] Further, such as Figure 5 As shown, the driving device includes a driving rod 20 rotatably connected to the inside of the fixed tube 8, the lower end of the driving rod 20 is fixedly connected to a first pulley 27, a second pulley 28 is arranged on one side of the first pulley 27, the second pulley 28 is rotatably connected to the lower end of the mounting ring 6, and a transmission belt is directly sleeved on the second pulley 28 and the first pulley 27; the lower end of the rotating plate 12 is coaxially fixedly connected to a matching gear 21, one side of the matching gear 21 is meshed with a driving gear 22, the driving gear 22 is rotatably connected to the lower end of the mounting ring 6, and when the driving gear 22 rotates 180 degrees, it can The driving gear 22 is located on the upper side of the second pulley 28 and is coaxially arranged with the second pulley 28. The corresponding ends of the second pulley 28 and the driving gear 22 are coaxially fixedly connected with the first bevel gear 25 and the second bevel gear 26. An incomplete bevel gear 24 capable of meshing is arranged between the first bevel gear 25 and the second bevel gear 26. The incomplete bevel gear 24 is rotatably connected to the lower end of the mounting ring 6. The lower end of the mounting ring 6 is fixedly connected with a driving motor 23. The power output end of the driving motor 23 is coaxially fixedly connected with the incomplete bevel gear 24. When the driving motor 23 rotates, the incomplete bevel gear 24 is driven to rotate. When the incomplete bevel gear 24 rotates, it first meshes with the second bevel gear 26 on the lower side to drive the second bevel gear 26 to rotate 180 degrees, and then drives the rotating cylinder 29 to rotate 180 degrees under the transmission of the first pulley 27, the second pulley 28 and the transmission belt and the driving rod 20, thereby completing the process of controlling the moving frame 5 to move downward, so that the clamp clamps the rubber strip and then moves upward to reset; Then, when the incomplete bevel gear 24 continues to rotate, it meshes with the first bevel gear 25 on the upper side, driving the driving gear 22 to rotate. When the driving gear 22 rotates, it meshes with the matching gear 21 to drive the matching gear 21 to rotate one circle. When the matching gear 21 rotates one circle, it can drive the rotating plate 12 to rotate one circle, thereby driving the clamp holding the rubber strip to rotate one circle around the rotating plate 12, so that the rubber strip is in a ring-shaped state. The driving motor 23 and the electric push rod 4 can be driven intermittently. After the driving motor 23 rotates one circle, it stops working. Then, the electric push rod 4 is controlled to move toward the molding machine so that the annular rubber strip is located on the upper side of the mold groove. Then, the driving motor 23 is controlled to rotate one circle to complete the process of moving the movable frame 5 downward to place the annular rubber strip into the mold groove, which facilitates the staff to load materials, can effectively improve work efficiency, and expand production.
