TECHNICAL FIELD

[0001] The utility model relates to a feeding equipment technical field especially a platform feeding mechanism. BACKGROUND

[0002] The conveying mechanism is the commonly used equipment in the production line, and the commonly used conveying equipment has conveying belts and conveying roller ways, and the driving of these conveying equipment is usually a motor, and the motor drives through a chain or a synchronous belt. SUMMARY

[0003] The utility model wants to solve the technical problem to provide a platform feeding mechanism, and the conveying efficiency is high, and the occupied area is small.

[0004] In order to solve the above technical problem, the technical scheme of the utility model is: a platform feeding mechanism, including base, with the sliding cooperation of base platform, first rack, with the first gear of first rack engagement, second rack, with the second gear of second rack engagement and cylinder, the base includes the bottom plate and the slide rail board being established at the both sides of bottom plate, the platform is established at the top of base, and the bottom of platform is equipped with the sliding slot of the sliding cooperation with the slide rail board, the first rack is equipped at the bottom surface of platform, the second rack is equipped on the bottom plate in the base, and the first rack is parallel with the second rack and is set apart, the first gear diameter is greater than the second gear diameter, the first gear and the second gear are equipped in the base and are connected through the connecting shaft, the cylinder is fixed on the base, and the telescopic rod of cylinder is connected with the bearing seat, and the connecting shaft passes through the bearing seat. The utility model principle: when the platform needs to be conveyed forward, the telescopic rod of cylinder is lengthened, and the cylinder drives the first gear and the second gear to move forward through the connecting shaft, since the second gear is engaged with the second rack, the connecting shaft rotates according to the engagement of the two, and the connecting shaft drives the first gear to rotate, since the first gear is engaged with the first rack, the platform moves forward, since the first gear diameter is greater than the second gear diameter, the distance of feeding platform relative to the base is in multiple relationship with the lengthening distance of cylinder, and the feeding distance is longer in the limited driving space.

[0005] As an improvement, one end of the bottom plate is provided with a mounting seat, the cylinder is fixed on the mounting seat, the bottom plate is provided with a groove, and the first gear is arranged in the groove.

[0006] The utility model compared with prior art has brought the beneficial effects of:

[0007] The cylinder drives the gear, the gear drives the rack, since the first gear diameter is greater than the second gear diameter, the distance of feeding platform relative to the base is in multiple relationship with the lengthening distance of cylinder, and the feeding distance is longer in the limited driving space. BRIEF DESCRIPTION OF DRAWINGS

[0008] Fig. 1 The utility model is a perspective view.

[0009] Fig. 2 The utility model is an end surface schematic view.

[0010] Fig. 3 The utility model is a plan view. DETAILED DESCRIPTION

[0011] The utility model is further described below in conjunction with the drawings of the specification.

[0012] As Figs. 1 to 3 A platform feeding mechanism, including base 1, with base 1 sliding fit platform 2, first rack 4, with first rack 4 meshing first gear 3, second rack 6, with second rack 6 meshing second gear 5 and cylinder 7.The base 1 is concave, it includes bottom plate and the slide rail board being arranged at the both sides of bottom plate, and the slide rail board is relative to slide rail;The platform 2 is arranged at the top of base 1, and the bottom of platform 2 is provided with the sliding slot of sliding fit with the slide rail board, and platform 2 can slide on base 1 along the slide rail board back and forth.The first rack 4 is arranged on the bottom surface of platform 2, and the second rack 6 is arranged on the bottom plate in base 1, and first rack 4 is parallel with second rack 6 and is arranged staggeredly, and the length direction of first rack 4 and second rack 6 is identical with the sliding direction of platform 2.The first gear 3 and second gear 5 are arranged in base 1, and the bottom plate is provided with recess, and the first gear 3 is arranged in recess, and the diameter of first gear 3 is greater than the diameter of second gear 5, and the first gear 3 is connected with second gear 5 through connecting shaft 8, and the rotation of second gear 5 on second rack 6 for a circle is equivalent to driving the rotation of first gear 3 for a circle, and the rotation of first gear 3 for a circle drives first rack 4 to translate corresponding distance.The one end of bottom plate is provided with mounting seat, and cylinder 7 is fixed on mounting seat, and the telescopic rod of cylinder 7 is connected with bearing seat, and connecting shaft 8 passes through bearing seat, and cylinder 7 drives two gears to move back and forth through connecting shaft 8.

[0013] The utility model principle: when platform 2 needs to be forwarded, the telescopic rod of cylinder 7 is lengthened, and cylinder 7 drives first gear 3 and second gear 5 to move forward through connecting shaft 8, because second gear 5 is meshed with second rack 6, so that connecting shaft 8 rotates according to the meshing of the two, and connecting shaft 8 drives first gear 3 to rotate, because first gear 3 is meshed with first rack 4, so that platform 2 moves forward, because the diameter of first gear 3 is greater than the diameter of second gear 5, so that the distance of feeding platform 2 relative to base 1 is in multiple relationship with the lengthening distance of cylinder 7, and presents the feeding distance of longer distance in the limited driving space.
