Abstract

An electric conduction path is provided between a central spindle winding a film roll and a support of a laminating machine, so static electricity is prevented from accumulating in the film roll in the laminating machine. According to the invention, two ends of the central spindle (11) rotate in an electric conduction plate (17) which contacts with the support (14) of the laminating machine. The plate (17) can be clamped between a pair of non-electric conduction discs (15, 18). The discs are used for allowing the plate (17) to be in position on the support (14).

Description

Laminating machine

Technical field

The present invention relates to the laminating machine of improvement, particularly relate to a kind of such laminating machine, which is provided with the device that can discharge the electrostatic that the mandrel rolled up by support membrane produces.

Background technology

In laminating machine, to be covered to the film on workpiece from be wound on mandrel film volume in be drawn out, mandrel supports by laminating machine support at two ends.This mandrel is at every one end place by disk supporting, and this disk forms bearing, and this mandrel rotates in this bearing, and this disk is supported by this support again.Due to economic cause, each disk is made up of nonconducting plastic material.In such an arrangement, film volume and mandrel and corresponding support electric insulation.This in use causes electrostatic can adversely accumulate in described film and mandrel, the user of this laminating machine that may shock by electricity.

Summary of the invention

Main purpose of the present invention is to provide the solution for the problems referred to above.

According to the present invention, a kind of supporting member for being rotatably supported in by mandrel on support is provided, wherein, this supporting member comprises the plate of conduction, this plate has the hole that rotates for mandrel and at least one outer surface for engaging with support within it, whereby this plate provide from this hole to this outer surface, for from this mandrel to the conductive path of this support release electrostatic.

In a preferred embodiment of the invention, this plate holder is located between pair of discs, and this is made up of non electrically conductive material disk.

The surface facing with each other of often pair of disk has groove, and described plate is positioned at these grooves.

Described plate is fixed on each disk by screw.Or each disk is fixed on relative disk by screw, described screw is through the respective aperture in this plate.

According to the present invention, a kind of laminating machine is also provided, wherein, the two ends that film on mandrel twists in this mandrel are supported by the support of conduction, wherein, this mandrel rotates in the plate of conduction, this plate engage with this support to provide from this mandrel to this plate and from this plate to this support, for from this mandrel to the path of this support release electrostatic.

Accompanying drawing explanation

Now, will preferred embodiment by non-limiting example and with reference to the accompanying drawings to describe the present invention, wherein:

Fig. 1 and Fig. 2 is main parallax stereogram and the rear perspective view of laminating machine respectively;

Fig. 3 and Fig. 4 is the enlarged side view of assembly and the front view at one end place of mandrel at support membrane volume respectively;

The decomposition view of the second embodiment of the assembly of Tu6Shi supporting mandrel one end.

Detailed description of the invention

As known per se, laminating machine 10 has mandrel 11 and 12, and mandrel 11 and 12 in use will support corresponding film volume, and described film will be pulled into the end face of workpiece and bottom surface to carry out lamination covering to it.In some laminating machinees, tertiary membrane is also had to be drawn out from the back side of laminating machine.For this object mandrel 13 as shown in Figure 2.

Fig. 3 and Fig. 4 is the enlarged drawing of arbitrary mandrel bearing " A " of Fig. 1 and Fig. 2.Each mandrel 11,12 supports with 13 supports 14 at its relative two ends by laminating machine 10.Aim to maintain it, this mandrel is rotating against the supporting member of the axle collar 16 be positioned on mandrel.

According to the present invention, supporting member comprises plate 17, this plate 17 by conductive material as steel or another ferrous metal are made.This plate 17 is folded between the first disk 15 and the second disk 18, and this first disk 15 and the second disk 18 make plate 17 be held in place on the support 14.Plate 17 has smooth side 19 and 20, and described side engages with the side slip of the groove 21 in support 14, thus this plate and this support electrical contact.Rotate in the centre bore 22 of mandrel 11 on plate 17, thus this mandrel and this plate electrical contact.So, between mandrel 11 and support 14, conductive path is provided, the electrostatic grounding that the rotation of the mandrel because of support membrane is gathered by this support.First disk 15 and the second disk 18 respectively have the centre bore of the centre bore 22 slightly larger than plate 17, thus the contact between supporting member and mandrel 11 realizes by means of only plate 17.

First and second disks 15,18 are fixed to the plate 17 be located in therebetween.In the fig. 4 embodiment, this by arranging realizing of a pair screwed hole 23 on plate 17.Each in first and second disks 15,18 is provided with non-threaded holes 24.This assembly through described non-threaded holes to engage to the corresponding screwed hole 23 on this plate, thus can be fixed together by screw 25.Each in first and second disks 15,18 comprises shallow slot 26 within it on the surface, and this shallow slot 26 provides the bearing of location-plate 17 to prevent relatively rotating between each disk and this plate.The degree of depth sum of two relative shallow slots 26 is less than the thickness of plate 17, thus outside the mid portion of each smooth side 19 and 20 of this plate is still exposed to after assembling.

Except mode disk 15 and 18 being fixed to plate 17 is different, the embodiment of Fig. 6 is identical with the embodiment in Fig. 5.In the present embodiment, each disk 15 and 18 is respectively provided with a hole 24 as previously mentioned and in the opposite side of centre bore, is respectively provided with the projection 27 extended inwardly.This projection 27 has central blind hole.Plate 17 is provided with a pair non-threaded holes 28, and their size is enough to receive corresponding projection 27 separately.Disk 15,18 is aimed at as illustrated in fig. 6 with plate 17, and self-tapping screw 29 is installed to coordinate with the blind hole in the projection 27 of relative disk through the hole 24 of each disk afterwards.Compared to the embodiment of Fig. 5, the present embodiment has two advantages: this assembly is more firm, because each disk 15 is all fixed to relative disk at two some places with 18, instead of each disk is only fixed to plate 17 at a some place; And manufacturing cost is lower, because the expense forming screwed hole 23 on plate 17 can be saved.

Should be appreciated that safety device of the present invention can be applied to have any amount of film dispensing mandrel laminating machine on.Some laminating machinees only have a film dispensing mandrel, and other have two or three films dispensing mandrel.
