Abstract
The utility model relates to a thermal rolling bonding device for a machine of making feminine napkins, which comprises an upper roller, a lower roller and heat bonding blocks respectively arranged on the upper roller and the lower roller. The utility model is characterized in that a load relief corner is respectively arranged in four edge corners of the working face of each heat bonding block. The utility model overcomes the undercut phenomenon of an original device when the non-woven fabric of feminine napkins is sealed, and has the advantages of reasonable structure, simple manufacture process, high stability, quality enhancement, reject rate reduction and production cost reduction.
Description
This utility model relates to the heat bond rolling device that a kind of manufacturing of sanitary napkins is used, and is the improvement to existing manufacturing of sanitary napkins.
Heat bond rolling is the device that non-woven fabrics seals usefulness in the sanltary towel production, and wherein the heat seal piece is the critical piece in the heat bond rolling device.In the prior art, the heat seal piece adopts simple structure mostly, and four corners of its work surface are the right angle, the edge of entire working surface is a linearity, in production sanitary towel, when non-woven fabrics need seal, two edge lines of heat seal piece directly contacted, because the impact of this device medi-spring pressure, make the initiating terminal of non-woven fabrics sealing part in the sanitary towel produce Undercutting Phenomenon, cause the sealing part easy fracture, influence the quality and the use of product, the percent defective height, and influence the outward appearance of sanitary towel.
The purpose of this utility model is to provide a kind of can make not easy fracture, attractive and durable of sanitary towel's sealing part, can improve the heat bond rolling device of the manufacturing of sanitary napkins of stabilization of equipment performance and product quality.
Technical solution of the present utility model is: comprise and roll 1 and roll down 2 and roll 1 and roll the upper and lower heat seal piece 3,3 ' of two couple who is oppositely arranged respectively on 2 down last, it is characterized in that four edges of the work surface of each heat seal piece are provided with off-load angle 4.
In this programme, infra rolls also to be equipped with on 2 and has the branching block 5 of shunting press strip on a pair of surface.
When this utility model uses, integral installation is on the big wallboard of manufacturing of sanitary napkins, transmission by the main frame train line drives the upper and lower commentaries on classics of rolling spin, make the heat seal piece seal mouth to non-woven fabrics two ends in the sanitary towel, simultaneously, by on rolling between the arc surface that rolls and the branching block that rolls on down contact, make on the lower surface of sanitary towel and extrude indenture.
The utility model has the advantages that: because four edges of heat seal piece work surface are established the off-load angle in manufacturing of sanitary napkins heat bond rolling device, when making the work of heat bond rolling device, under the spring impulsive force, the off-load angle of upper and lower heat seal piece receives earlier impulsive force, when treating that working edge place on the heat seal piece touches sanitary towel and do not have gauze and seal top, there has not been impulsive force, this just makes that sanitary towel has avoided Undercutting Phenomenon, thereby can improve the product quality of sanitary towel, reduce percent defective, reduce production costs; Also owing in this device, increased branching block, make the common sanitary towel that produces fully to absorb moisture content, thereby improved the inherent quality of sanltary towel simultaneously.
Following accompanying drawing has been described embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is this utility model working state structure sketch map;
Fig. 3 is the structural representation of heat seal piece in this utility model;
Fig. 4 is the B-B profile of Fig. 3;
Fig. 5 is the structural representation of branching block in this utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.As shown in Figure 1, this utility model comprises and rolls 1 and roll down 2 and roll 1 and roll the upper and lower heat seal piece 3,3 ' of two couple who is oppositely arranged respectively on 2 down last, wherein, four edges at the work surface of each heat seal piece are provided with off-load angle 4, and off-load angle 4 processes (seeing Fig. 3, Fig. 4) with the solid forging of heat seal piece.The heat seal piece is provided with screw, be installed in respectively by bolt roll 1 and under roll on 2.Under roll branching block 5 also be housed on 2, be shaped on the shunting press strip of projection on the surface of branching block 5, the shunting press strip is welded on the matrix of branching block, the size of press strip and concrete shape can design according to customer requirements, in the present embodiment, this press strip is the circular curve (see figure 5) of disjoint two projectioies, and branching block 5 is installed in down by bolt and rolls on 2.For ease of installing, upper and lower rolling with the junction of heat seal piece, branching block made platform 11 and 21, shown position with Fig. 2 is an example, the a pair of heat seal piece 3 of going up is installed on the platform 11 that rolls 1 upper and lower surface, on roll 1 the left and right sides and roll 1 arc surface itself on being, a pair of down heat seal piece 3 ' is installed in down on the platform 21 that rolls 2 upper and lower surface, branching block 5 is installed in down on the platform 21 that rolls 2 the left and right sides, on roll the last heat seal piece 3 installed on 1 with on roll between 1 the arc surface itself and time roll between the following heat seal piece 3 ' of installation on 2 and the branching block 5 90 ° of angles each other.Main frame is sent to power in this device, make down and roll 2 and be rotated counterclockwise, the transmission of a pair of gear by the identical number of teeth, make and roll 1 and turn clockwise, be installed in the last heat seal piece 3 that rolls on 1 and roll contacting between 2 the following heat seal piece 3 ' down, finish the heat-sealing mouth technology at non-woven fabrics two ends in the sanitary towel, under the impulsive force of the spring that in this device, is provided with, at first by two off-load angles 4 contact earlier separately of the side on the heat seal piece work surface, receive impulsive force by off-load angle 4, when the work surface edge on the heat seal piece touches sanitary towel's non-woven fabrics and seals top, there has not been impulsive force, make sanitary towel avoid Undercutting Phenomenon, thereby can improve the production and the service property (quality) of stability of the present utility model and sanitary towel, reduce percent defective.When upper and lower lift-over is crossed 90 °, on roll the arc surface on 1 and roll down cooperations of rolling of branching block on 2, make the lower surface of sanitary towel extrude twice circular arc indenture curve, can make the menses can be, the water absorption of increase sanitary towel fully to the both sides diffusion.Upper and lower 360 ° of the revolutions that roll are finished the heat seal and the action of branching block impression of two sanitary towels.
