The rubber ring edge trimming and fixing device includes: a uniform clamping mechanism, the uniform clamping mechanism includes a rotating disk, the uniform clamping mechanism is used to clamp and reinforce the rubber ring, the outer surface of the rubber ring is clamped by an outer clamping rod and the inner surface of the rubber ring is clamped by an inner clamping rod, so that the clamping force reaches a balanced state, and at the same time, the outer clamping rod and the inner clamping rod clamp the inner and outer rings of the rubber ring at the same time, so that the stress on the rubber ring can be evenly distributed, so that the stress concentration in a certain area can be avoided, so that the rubber ring is more evenly stressed, thereby preventing the rubber ring from being deformed and improving the quality of trimming the rubber ring;

[0005] During use, the existing rubber ring trimming machine can support rubbers of different sizes by adjusting the distance of the positioning components. However, the curvature of the positioning components is fixed, so that it is impossible to fit with rubber rings of different sizes, resulting in uneven force on the support points, thereby affecting the trimming accuracy. At the same time, when trimming large-sized rubber rings, it is inconvenient to automatically cut and collect the cut waste edges, so that when the cut flash edges are connected for a long time, the accuracy of the flash cutting point will be affected, and it is inconvenient to collect the flash waste.

DETAILED DESCRIPTION

[0044] 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.

[0045] Example 1: Please refer to Figure 1-Figure 7 and Fig. 9 As shown, although the existing rubber ring trimming machine can adjust the position of the clamping mechanism to achieve the limit of rubber rings of different diameters, the arc of the clamping mechanism remains unchanged, making it impossible to fully fit rubber rings of different sizes, thereby causing uneven support force on the rubber ring, which easily causes the rubber ring to deform and affect the trimming accuracy. In order to solve this technical problem, this embodiment discloses the following technical content;

[0046] A rubber ring trimming machine for recycling waste materials comprises a base 1 stably placed in a processing workshop, a guide groove 2 is evenly opened on the upper end of the base 1, a slide seat 3 is slidably arranged on the inner side of the guide groove 2, a first motor 4 is fixedly installed on the inner side of the base 1, and a turntable 5 is fixedly installed on the output end of the first motor 4, and the turntable 5 drives the slide seat 3 to slide, and a collection groove 28 for receiving dropped flash is fixedly installed on the outer side of the base 1;

[0047] The threaded rod 7 is rotatably mounted on the upper end of the sliding seat 3, and a sliding sleeve 8 is connected to the outer side of the threaded rod 7, and a limiting rod 9 is fixedly installed on the outer side of the sliding sleeve 8 to prevent the sliding sleeve 8 from rotating synchronously with the threaded rod 7; the first clamping plate 10 is rotatably mounted on the outer end of the threaded rod 7, and a first pull rod 13 is hinged between the first clamping plate 10 and the sliding sleeve 8 to adjust the curvature of the first clamping plate 10 to improve the clamping accuracy, and a second clamping plate 14 is symmetrically slidably mounted on the first clamping plate 10, and an adjusting component is arranged between the first clamping plate 10 and the second clamping plate 14 to adjust the position of the second clamping plate 14, and a support plate 1001 is integrally arranged on the outer side of the middle position of the lower end of the first clamping plate 10;

[0048] The transmission assembly is arranged between the base 1 and the threaded rod 7. The threaded rod 7 is driven to rotate synchronously by the transmission assembly during the movement of the slide 3. The slide 3 passes through the guide groove 2, and the slide 3 slides and adjusts along the guide groove 2. A sliding ball 301 is arranged at the lower end of the slide 3. At the same time, the upper surface of the turntable 5 is evenly provided with arc-shaped slide grooves 6, and the sliding ball 301 slides along the slide groove 6. The transmission assembly includes a rack 11 fixedly mounted on the surface of the base 1, and the upper part of the rack 11 is meshed and connected with a first gear 12, and the first gear 12 is rotatably mounted on the outer side of the slide 3. At the same time, the shaft of the first gear 12 and the shaft of the threaded rod 7 are connected by a bevel gear transmission assembly. The threaded rod 7 is threadedly connected to the sliding sleeve 8, and the limit rod 9 fixedly mounted on the sliding sleeve 8 passes through the slide 3 and forms a telescopic structure with the slide 3.

[0049] A first pull rod 13 is symmetrically hinged between the sliding sleeve 8 and the two ends of the first clamping plate 10, and the first clamping plate 10 is arranged in an arc-shaped structure, and the first clamping plate 10 is made of elastic metal material, and the arc of the first clamping plate 10 is gradually adjusted under the pulling of the first pull rod 13. Two second clamping plates 14 are symmetrically arranged about the first clamping plate 10, and the curvature of the second clamping plate 14 is the same as that of the first clamping plate 10, and the second clamping plate 14 will be synchronously adjusted and shaped when the arc of the first clamping plate 10 is adjusted. The adjusting assembly includes a connecting block 15, a first telescopic rod 16 and a second pull rod 17, and the connecting block 15 is fixedly installed on the upper end of the second splint 14, and the second splint 14 and the connecting block 15 are both slidably connected to the first splint 10, and the first telescopic rod 16 is fixedly installed on the upper end of the first splint 10, and at the same time, a second pull rod 17 is connected between the output end of the first telescopic rod 16 and the connecting block 15, the outer walls of the first splint 10 and the second splint 14 are flush and both fit the inner wall of the rubber ring, and there is a gap between the second splints 14 on two adjacent first splints 10 after being pushed out.

[0050] By adopting the above technical solution, when the rubber ring needs to be trimmed, the first motor 4 is started according to the inner diameter size of the rubber ring, so that the first motor 4 drives the turntable 5 to rotate, so that the sliding ball 301 at the lower end of the slide seat 3 slides along the slide groove 6, thereby driving multiple slide seats 3 to slide and adjust synchronously along the guide groove 2, and then the rubber ring is sleeved on the outer sides of multiple first clamps 10. At this time, the support plate 1001 can support the rubber ring, and then continue to control the movement of the slide seat 3 so that the first clamp plate 10 is supported on the inner wall of the rubber ring. During the movement of the slide seat 3, the first gear 12 will mesh with the rack 11, and then the first gear 12 will drive the threaded rod 7 to rotate synchronously through the bevel gear transmission member, so that the threaded rod 7 drives the sleeve 8 to adjust on its outer side, and during the movement of the sleeve 8, it will synchronously pull the two ends of the first clamp plate 10 through the first pull rod 13, so that the first clamp plate 10 is deformed to a circular shape. The adjustment of the curvature allows the first splint 10 to fully fit the rubber ring of the corresponding diameter size. When the first splint 10 is deformed, it will synchronously drive the second splint 14 embedded in its outer side to deform and shape synchronously, so that the curvature of the first splint 10 and the second splint 14 is the same. Then the first telescopic rod 16 is controlled to pull the second pull rod 17, so that the second pull rod 17 pushes the connecting block 15, so that the connecting block 15 drives the second splint 14 to slide and unfold to both sides of the first splint 10, thereby achieving full support for the rubber ring and avoiding deformation of the rubber ring during the limiting process and affecting the trimming effect. When the second splint 14 is extended and unfolded, a gap is reserved at the end of the second splint 14 on the two adjacent first splints 10, so that the first splint 10 can be slightly retracted when the rubber ring is removed. When the curvature of the first splint 10 needs to be adjusted again, the first telescopic rod 16 is controlled to drive the second splint 14 to slide and retract.

[0051] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. The existing rubber ring trimming machine is not convenient for automatically cutting and collecting the cut waste edges when trimming large-sized rubber rings, so that when the cut burrs are connected for a long time, the accuracy of the burr cutting point will be affected, and it is not convenient to collect the burr waste. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 3 and Figure 8As shown, the second motor 18 is fixedly mounted on the inner side of the base 1, and the output end of the second motor 18 is fixedly mounted with a second gear 19; the rotating ring 20 is rotatably mounted on the outer side of the base 1, and the outer side of the rotating ring 20 is fixedly connected with a bracket 21, and the upper end of the bracket 21 is fixedly mounted with a second telescopic rod 22, and the output end of the second telescopic rod 22 is fixedly mounted with a trimming knife 23, and at the same time, a slitting mechanism is also installed on the outer side of the bracket 21 to achieve slitting of the trimmed flash. The second gear 19 penetrates the base 1 and is meshed with the tooth blocks evenly arranged on the inner wall of the rotating ring 20, and the rotating ring 20 drives the bracket 21 to rotate circumferentially around the base 1, and the trimming knife 23 connected to the output end of the second telescopic rod 22 fits the outer wall of the rubber ring to achieve the removal of the flash.

[0052] The slitting mechanism includes a guide column 24 elastically and telescopically mounted on the bracket 21, and the guide column 24 passes through the bracket 21, and a slitting knife 27 is fixedly mounted on one end of the bracket 21 close to the trimming knife 23, and a movable plate 25 is fixedly mounted on one end of the bracket 21 close to the collecting groove 28, and a first magnetic block 26 is fixedly mounted on the lower end of the movable plate 25, and second magnetic blocks 29 are evenly fixed on the inner wall of the collecting groove 28, and the first magnetic block 26 will intermittently pass by the second magnetic block 29 at different positions during its rotation, and the magnetic poles of the opposite surfaces of the first magnetic block 26 and the second magnetic block 29 are the same.

[0053] Through the above technical solution, when the rubber ring is fixed, the first telescopic rod 16 is controlled to push the trimming knife 23 to move and fit the outer side of the rubber ring, and then the second motor 18 is started, so that the second motor 18 drives the second gear 19 to rotate. At this time, the second gear 19 can mesh with the tooth block set inside the rotating ring 20, thereby driving the rotating ring 20 to rotate synchronously. At this time, the rotating ring 20 will drive the trimming knife 23 to rotate circumferentially around the rubber ring through the bracket 21, so as to realize automatic trimming of the flash on the outer side of the rubber ring. As the bracket 21 rotates, the first magnetic block 26 on the movable plate 25 on its outer side will intermittently pass through the second magnetic block 29 at different positions, so that the movable plate 25 will drive the guide column 24 to elastically expand and contract under the action of magnetic force, so that the slitting knife 27 at the end of the guide column 24 can automatically and evenly cut the trimmed flash, ensuring that the flash can fall evenly into the collection tank 28 for recycling.
