Specific implementation mode
In order to be best understood from the technology of the present invention content, be provided below specific embodiment, and in conjunction with attached drawing to the present invention do into The explanation of one step.
Referring to Fig. 1 to 4, a kind of continuous pushing cover device, including slip lid slot 1, the cover board 2 on slip lid slot 1 and fixed plate 3, further include front swing arm 4 and side-sway arm 5, the front swing arm 4 is located at the centre position of the outbound course of the slip lid slot 1;It is described Side-sway arm 5 is separately mounted to the both sides of the outbound course of the slip lid slot 1, and is symmetric;The centre of the fixed plate 3 is set There is the first spring base 6, both sides are respectively equipped with second spring seat 7, are equipped with the first spring return mechanism in the first spring base 6, and second Second spring resetting-mechanism is equipped in spring base 7;4 front end of the front swing arm is equipped with the first idler wheel 8 of several horizontal directions rotation, 4 middle part of the front swing arm is mounted on by first rotating shaft 9 on the first spring base 6, the rear end of the front swing arm 4 and first bullet Spring resetting-mechanism connects;5 front end of side-sway arm is equipped with the second idler wheel 10 of vertical direction rotation, and 5 middle part of the side-sway arm is logical The second shaft 11 is crossed on the slip lid slot 1, the rear end of the side-sway arm 5 is connect with the second spring resetting-mechanism. The continuous pushing cover device of the present invention carries out auxiliary pushing bottle cap from Bottle cap top by 4 idler wheel of front swing arm of front end and transfers out, with And promotion conveying is carried out by the 5 pair of rollers bottle cap of side-sway arm of both sides, the conveying that collaboration combs bottle cap is carried out in three-dimensional so that Combing is more smooth, effectively prevents screens phenomenon.The direction of rotation of idler wheel in swing arm complies with bottle cap and skids off direction, can not only Enough bottle caps that combs well are conveyed, and reduce the frictional force between bottle cap, and traditional plates is effectively avoided to connect It touches and the problem of screens occurs, improve the speed of conveying bottle cap.It carries out resetting front swing arm 4 and side-sway arm 5 by spring return mechanism, It is simple in structure, it resets timely and effective.
Further, first spring return mechanism includes jackscrew 601, thimble 602 and spring 603, the jackscrew 601 It is connect with one end of the thimble 602 by spring 603, the other end of the thimble 602 and the rear end of the front swing arm 4 connect It connects.Equally, 603 resetting-mechanism of the second spring includes jackscrew 601, thimble 602 and spring 603, and the jackscrew 601 passes through bullet Spring 603 is connect with one end of the thimble 602, and the other end of the thimble 602 is connect with the rear end of the side-sway arm 5.
Operation principle:During conveying bottle cap, when bottle cap comes out, front swing arm 4 is up put, and is rotated by first rotating shaft 9, By the rotation of first rotating shaft 9, thimble 602 presses to spring 603 in 603, spring, and the first idler wheel 8 is buckled in the top of bottle cap at this time Portion, rotating direction and the bottle cap of the first idler wheel 8 skid off that direction is consistent, and 8 rolling action of the first idler wheel is moved along conducive to bottle cap, phase When in pushed away when bottle cap is gone out it one so that be not in when bottle cap transfers out friction screens the problem of so that Bottle cap, which more easily slips out, to be come;When bottle cap leaves front swing arm 4, the thimble 602 resets.Similarly, when bottle cap skids off, 2 side-sways 5 front end of arm is flared out the side wall of fitting bottle cap, and by the rotation of the second shaft 11,602 stress of thimble presses to spring at this time 603, spring 603 is shunk, and on bottle cap outbound course, it is consistent that the rotating direction of the second idler wheel 10 with bottle cap skids off direction so that bottle Lid easily skids off, and when bottle cap leaves side-sway arm 5,5 front end of side-sway arm is inwardly closed, and thimble 602 resets, 603 homing of spring.It is right Than traditional approach, the first idler wheel 8 and the rotation of the second idler wheel 10 skid off bottle cap, and frictional force is small between idler wheel and bottle cap, makes It obtains bottle cap and conveys remarkable result that is smooth, being not easy screens.
In the present embodiment, the first idler wheel 8 is mounted on the front end of front swing arm 4 by a shaft core, and shaft core passes through opening pin 12 are installed on the front end of front swing arm 4 so that it is more firm on front swing arm 4 that shaft core is fixed on, and the front swing arm 4 is Z-shape, is conducive to Front swing arm 4 presses bottle cap;Second idler wheel 10 is mounted on the front end of side-sway arm 5 by a shaft core, and shaft core upper end is solid by nut 13 It is scheduled on side-sway arm 5, the side-sway arm 5 is arc shape, is conducive to side-sway arm 5 and is bonded bottle cap.In other embodiments, before described Swing arm 4 can be L-shaped, and the side-sway arm 5 can be Z-shaped.
Embodiment 2
Referring to Fig. 5 to 6, difference lies in set the present embodiment between the front swing arm 4 and the fixed plate 3 with embodiment 1 It is useful for adjusting the limiting component 14 of 4 swing angle of front swing arm, the limiting component 14 is mounted on described through the front swing arm 4 In fixed plate 3.The limiting component 14 can be screw, screw rod or bolt.Adjust the i.e. adjustable forward swing of height of limiting component 14 The angular range that arm 4 is swung up and down so that the continuous pushing cover device of the present invention is suitable for conveying the bottle cap of different height so that application More extensively.
Embodiment 3
Referring to Fig. 7 to 8, the present embodiment the difference from example 2 is that, the cover board 2 be equipped with several hollow groove bodies 200, the cover board 2 is fixed on by magnetic absorption on the slip lid slot 1.2 periphery of the cover board is equipped with the first adsorption tank 201, first adsorption tank 201 is interior to be equipped with the first adsorbent 202, and the slip lid slot 1 is equipped with and first adsorption tank 201 Corresponding second adsorption tank 203, is equipped with the second adsorbent 204 in second adsorption tank 203, the first adsorbent 202 and the Two adsorbents, 204 magnetic suck connects.Wherein, first adsorbent 202, the second adsorbent 204 are magnet;Or described One adsorbent 202 is magnet, and the second adsorbent 204 is ferromagnetic metal body;Or first adsorbent 202 is ferromagnetism gold Belong to body, the second adsorbent 204 is magnet.Ferromagnetic metal body is iron, nickel, cobalt or its alloy.
