Detailed Description

Referring to the attached drawings, the positioning device of the gold stamping die-cutting machine is provided with a machine body 2, an impression unit and two parallel and closed transmission chains 1, wherein the impression unit has one or a combination of gold stamping, indentation, die cutting and waste cleaning functions; the stamping unit comprises a lower fixed platform 3 and an upper movable platform 4, a gripper bar body 8 is connected to a transmission chain 1, a positioning groove 10 is fixed at the input end or the output end of the stamping unit, a sliding seat 18 is fixed on the transmission chain 1, a sliding block 13 is arranged on the sliding seat 18, the sliding block 13 is connected with the gripper bar body 8 through an adjusting mechanism, the adjusting structure is common knowledge in the field, such as an adjusting pin or an adjusting gasket structure disclosed in the background document CN205836221U, the gripper bar body 8 is fixedly connected with a gripper bar 17, the gripper bar body 8 is matched with the positioning groove 10, and the sliding block 13 is in contact with a moving part during action. Specifically, when the positioning device is a positioning device at the output end of the stamping unit, a support 14 is fixed on one side of the positioning slot 10, the support 14 is provided with the movable member which slides up and down, the movable member is a top rod 16, the top rod 16 is in contact with the upper movable platform 4, and the top rod 16 is in contact with the slide block 8 during operation. When the slide block moves to the position above the positioning groove 10 along with the transmission of the slide seat, the upper movable platform 4 moves downwards, the upper movable platform 4 presses the ejector rod 16, the ejector rod 16 moves downwards to push the slide block 13 to slide downwards, and therefore the slide block 13 is sunk into the positioning groove 10 to realize rear positioning. When the positioning device is a positioning device at the input end of the stamping unit, the positioning device is positioned in the following way: namely, the movable piece is arranged on the chain wheel shaft 22 of the transmission chain 1, the movable piece is a swing arm cam 23, the swing arm cam 23 rotates along with the rotation of the chain wheel, when the swing arm cam 23 contacts with the slide block 13, the slide block 13 is driven to slide downwards, and the slide block 13 is matched with the positioning groove 10 arranged at the position after sliding downwards, so that the front positioning is realized. And the swing arm cams 23 are also symmetrically provided on the sprocket shaft 22. For the rear positioning of the output end of the stamping unit, a mandril 16 of the stamping unit is provided with a first inclined surface 11, and a slide block 13 is provided with a second inclined surface 12 matched with the first inclined surface 11. Therefore, when the mandril 16 descends, the first inclined surface 11 of the mandril contacts the second inclined surface 12 on the slide block 13 first, so that the tooth row is prevented from slightly shaking in the moving process, and the left and right positioning is realized. In this embodiment, the slide carriage 18 is provided with a guide rod 19, the guide rod 19 is provided with a first spring 20, and the slide block 13 is sleeved on the guide rod 19. After the movable member 16 moves down along the guide rod 19 against the slider 13, the first spring 20 thereof is compressed, and when the movable member is disengaged from the slider, the movable member will carry the slider 13 to return automatically due to the elastic force of the first spring 20. The notch of the positioning slot 10 at the output of the embossing unit is provided with a roller 9, the roller 9 being arranged with the aim that, when the slider 13 descends, the side wall of the slider 13 comes into contact with the roller 9, so that the slider 13 falls more easily into the positioning slot 10. Because the utility model discloses the action of its slider of location behind the impression unit relies on the work of last movable platform 4, therefore, need go up movable platform 4 and go up and down through one set of lifting structure, so, be equipped with a pair of drive gear 5 in the organism, the one end of swing arm 6 is connected eccentrically on drive gear 5, movable platform 4 is connected to the other end of swing arm 6, a pair of drive gear 5 passes through the meshing of gear train 7, after gear train 7 passes through 24 input transmission power of motor power, just make gear train 7 take a pair of drive gear 5 to rotate, because its swing arm 6 is eccentric connection with drive gear 5, therefore, 5 transmission a week of drive gear, alright in order to take movable platform 4 to accomplish a lift process. Further, the jack 16 thereof is installed by: the support 14 is provided with a through hole, the ejector rod 16 penetrates through the through hole, the lower end of the ejector rod 16 can be contacted with the sliding block 13, the part of the ejector rod 16 exposed out of the upper part of the support 14 is sleeved with a second spring 15, the upper part of the ejector rod 16 is provided with a flange 21, and the support 14 of the second spring 15 is used as a support table for the second spring 15 after the second spring 15 is sleeved between the flange 21 and the support 14. After the upper movable platform 4 goes down, the second spring 15 is pressed, and after the upper movable platform 4 rises, the mandril 16 can return by itself under the action of the elastic force of the second spring 15.

The structure of the utility model is applied to indentation, gold stamping, die cutting or waste clearing of the film, when the gripper bar 17 holds the film into the impression unit, the upper movable platform 4 moves downwards, drives the mandril 16 to move downwards, the mandril 16 pushes the slide block 13 to move downwards to match with the positioning groove 10, realizes post positioning, and the left and right positioning is realized after the inclined plane of the mandril 16 is matched with the inclined plane of the slide block 13, and simultaneously, the rotation of the chain wheel shaft 22 drives the swing arm cam 23 to rotate, so that the swing arm cam 23 can realize movable contact with the slide block 13, and because the processing object is a film, the whole film does not float locally like paper, the teeth row 17 is driven to move integrally in the process of moving up and down under the action of the sliding block, therefore, the positioning device realizes front and back positioning and left and right positioning, has the characteristics of simple structure, accurate and reliable positioning and long service life, and brings good technical effect to the mass post-printing processing of films.
