Abstract
The utility model relates to A translational sealing mechanism of a packaging machine and comprises a cam, shear-shaped arms, a contracting spring, a push rod and a thermal sealing substrate; wherein, the inner side of the thermal sealing substrate is provided with a U-shaped thermal sealing body, a cutter and a drawing bag wheel; the middle parts of the two shear-shaped arms are rotationally connected by a medial axis; two push rods are relatively vertical with each other and are connected with one end of each shear-shaped arm; the other ends of the two push rods are contacted with a cam face; the contracting spring connects the two shear-shaped arms together; the drawing bags wheel is arranged between the cutter and the U-shaped thermal sealing body; the back of the thermal sealing substrate which is arranged between the other end of the shear-shaped arm is provided with vertical slid bars and every slid bar is separately fixed at a crate by a linear bearing and a bearing chock; and the slid bars are rotationally connected with the shear-shaped arms. With the slid bar and the linear bearing, two thermal sealing substrates are always kept parallel to ensure that the sealing surface is stressed uniformly and the sealing quality is guaranteed and also the incision is kept trim. Because the weight of the thermal sealing substrates is borne by the crate, the burden of the shear-shaped arm is relieved and the structural rigidity is improved.
Description
Technical field
The utility model relates to a kind of heat sealing wrapping machine, particularly the translation sealing mechanism of wrapping machine.
Background technology
The sealing mechanism of existing this type of wrapping machine is: have cam driven both arms that rotate to do reciprocal opening and closed action in the middle of a pair of power arm of scissor arm, the relative inner of its resistance arm respectively connects a heat-sealing mainboard, and a U-shaped hot body and a cutting knife arranged respectively at the bottom thereon; Make two just in time parallel closures of U-shapeds heat-sealing body when two arms are closed, make the packaging bag heat seal that is positioned at its centre bonding, following cutting knife cuts the bag of sealing simultaneously.There is following shortcoming in this sealing mechanism:
1, is variable angle owing to cultrating between the both arms, makes two heat-sealing bodies parallel, only make it at the position of involution keeping parallelism, but this parallel optimum regime that is difficult for adjusting to, and, cause the sealing surface discontinuity along with the wearing and tearing of rotary part can destroy its parallelism, influence the involution quality.
2, in the process sheared of cutting knife bag is produced thrust to edge of a knife angle opposite, otch is tilted, especially more obvious when shaped cutouts.
3, heat-sealing mainboard and shear arm direct connection, its weight is all born by shear arm, poor structure rigidity.
Summary of the invention
The purpose of this utility model just provides a kind of parallel sealing mechanism that makes heat-sealing body keeping parallelism, raising involution and kerf quality, improves the wrapping machine of structural rigidity.
The purpose of this utility model realizes by following technical proposals: comprise cam, scissor arm, extension spring, push rod, heat-sealing substrate, U-shaped heat-sealing body, cutting knife arranged in the inboard of heat-sealing substrate and draw the bag wheel, two scissor arms middle part is rotationally connected by axis, two push rods are vertically connected on an end of each scissor arm relatively, the other end of two push rods contacts with camming surface, extension spring is connected between two scissor arms, and strap wheel is between cutting knife and U-shaped shape heat-sealing body.Described heat-sealing substrate is between the scissor arm other end, and all there is vertical slide bar at its back side, and every slide bar respectively holds by a linear axis and bearing seat is fixed on the cabinet; Be rotationally connected between slide bar and the scissor arm.
Described slide bar has four, respectively has one in each top and the bottom that seal the back side of substrate, and the slide bar on described shear arm and top is rotationally connected.
Rotation connection structure between described slide bar and the scissor arm is: a cylinder keyway is radially arranged on slide bar, and there is a T-shaped key at corresponding above-mentioned keyway place, its top and above-mentioned keyway bearing fit in the scissor arm end.
Described cutting knife is the profile of tooth cutting knife.
The utility model has the advantages that: make two heat-sealing substrates remain parastate by slide bar and linear bearing, make sealing surface stressed evenly, guarantee the involution quality, in like manner also make otch keep smooth; Because the heat-sealing substrate is born weight by cabinet, has alleviated the burden of scissor arm, has improved its structural rigidity.
The utility model is described in further detail below in conjunction with drawings and Examples.
