Abstract
The utility model relates to a closing apparatus with quick backward and slow forward functions, comprising two closing plates, a swing rod, two closing arms, two linear bearings. Two closing plates are respectively connected with the two closing arms coaxially faced with each other. Two linear bearings are respectively arranged in the axes of the closing arms; two radial directional rods on the outer sides of the closing arms are respectively gearedly connected with one end of one swing rod. The utility model also comprises two transmission mechanisms connected with the other ends of the swing rods, each composed of a guide rod, a slider, an inertia crank, an eccentric shaft and a universal connecting rod, wherein the guide rod is arranged vertical to the closing arms; the slider is slide connected with the guide rod; an asymmetric grooved rail is arranged on one side of the slider; the inertia crank is positioned on the side of the slider with the grooved rail; the eccentric shaft is vertically connected with the inertia crank. The utility model is characterized in that with the eccentric shaft on the inertia crank sliding along the asymmetric grooved rail on the slider, the slider can be moved to slide along the slide rod at different speeds and the driven swing rod has different swinging speeds at different directions so that low speed when moving forward and fast speed when moving backward are realized to meet the requirements of packaging materials with different specifications. The utility model has the advantages of stable and reliable transmission, low noise, compact structure, convenient adjustment, high precision and good centering.
Description
Technical field
The utility model relates to packaging facilities, particularly a kind of slow forward fast backward sealing mechanism.Be used on the wrapping machine involution to packing.
Background technology
The involution of China's existing dress shape wrapping machine generally adopts cam mechanism, noise more greatly, not steadily, adjust inconvenient, the large-scale many Volleyball Associations of incompatibility bag packing, structure is not compact, precision is difficult to improve, and is poor to neutrality.
Summary of the invention
The purpose of this utility model just provides that a kind of stable drive is reliable, noise is lower, compact conformation, easy to adjust, precision is high, the slow forward fast backward sealing mechanism good to neutrality.
Technical solutions of the utility model are: comprise the involution plate, fork, the involution arm, linear bearing, two involution arms are coaxial relatively, its relative end respectively connects an involution plate, there is linear bearing in axle center at the involution arm, there is radial bars in the outside of involution arm, and each is in transmission connection with a fork one end, also comprise other end bonded assembly transmission device with described fork, it comprises guide rod, slide block, the inertia crank, eccentric shaft, Universal linking lever, guide rod is vertical with described involution arm, slide block and guide rod sliding block joint, side at this slide block has asymmetric grooved rail, the inertia crank is positioned at the side that this slide block has grooved rail, the eccentric shaft end that is vertically connected on the inertia crank is positioned at described slide block grooved rail, and both bearing fits are connected with the other end of described fork by Universal linking lever in the position of slide block with the equidistant symmetry of guide rod.
Described fork is formed by two sections hinges, at its hinging place damping spring is arranged, and its hypomere middle part is connected with frame by rotating shaft, in its hypomere lower end shift fork is arranged, and is described involution arm radial bars outer end in this shift fork.
The regulating mechanism that also comprises the radial position on the inertia crank of described eccentric shaft.
The utility model utilizes the eccentric shaft on the inertia crank to slide along the non-symmetrical rail groove on the slide block, thereby speed change area movable slider moves along slide bar, the speed difference that driven fork is swung when different directions, thereby realize the slow forward fast backward of involution, can satisfy the requirement of different size packing.Have that stable drive is reliable, noise is lower, compact conformation, easy to adjust, precision is high, the advantage good to neutrality.

The specific embodiment
Referring to Fig. 1-Fig. 3, the utility model comprises involution plate 11, fork 5, involution arm 12, linear bearing 13, two involution arms 12 are coaxial relative, its relative end respectively connects an involution plate 11, in the axle center of involution arm 12 linear bearing 13 is arranged, there is radial bars 14 in the outside of involution arm 13, and each is in transmission connection with the lower end of a fork 5.Also comprise upper end bonded assembly transmission device with described fork 5, it comprises guide rod 1, slide block 2, inertia crank 4, eccentric shaft 3, Universal linking lever 6, guide rod 1 is vertical with described involution arm 12, slide block 2 and guide rod 1 sliding block joint, side at this slide block 2 has asymmetric grooved rail 21, inertia crank 4 is positioned at the side that grooved rail 21 is arranged of this slide block 2, the end that is vertically connected on the eccentric shaft 3 on the inertia crank 4 is positioned at described slide block grooved rail 21, both bearing fits are connected by the upper end of Universal linking lever 6 with described fork 5 in the position of slide block 2 with guide rod 1 equidistant symmetry.
Described fork 5 is hinged by epimere 51 and hypomere 52 and forms, at its hinging place damping spring 9 is arranged, the middle part of its hypomere 52 is connected with frame by rotating shaft 10, in the lower end of its hypomere 52 shift fork 53 is arranged, and is the driving lever on the outer end of described involution arm radial bars 14 in this shift fork 53.
Also be provided with the regulating mechanism of eccentric shaft 3 radial position on inertia crank 4.To satisfy different involution needs.This regulating mechanism can adopt on coherence crank 4 and leave radial slot with the junction of eccentric shaft 3, and eccentric shaft 3 can be fixed on the diverse location of radial slot with nut.
Principle of work of the present utility model is: when 4 rotations of inertia crank, drive eccentric shaft 3 and do the concentric rotation, eccentric shaft 3 drives slide blocks 2 and slides up and down along guide rod 1, slidably reciprocates in the asymmetric grooved rail 21 of slide block 2 simultaneously.It is that fulcrum swings with rotating shaft 10 that slide block 2 drives fork 5 by Universal linking lever 6, and the lower end of fork 5 is stirred involution arm 12 and driven involution plate 11 and does the opening and closing campaign, realizes involution.Because the rail groove 21 of slide block 2 inboards is asymmetric, so the speed that slide block 2 moves up and down is inconsistent, the speed that promptly moves down is fast, the speed that moves up is slow, the speed that swings of fork 5 is just inconsistent like this, is that two involution plates 11 are slower when closing up when showing involution, and very fast when opening.
