Abstract

The utility model relates to a closure machine, which can be used for the bag sealing of plastic film. The utility model comprises an upper machine base and a lower machine base which is movably connected with the upper machine base; tooth-shaped heating sheets joggled together are arranged on the ends of the upper machine base and the lower machine base. The closure machine can be held by hands or covered on a working table when used, a bag mouth can be extended and put on the tooth-shaped heating sheets of the lower machine base, and the bag mouth heat seal can be realized by switching on a power supply and pressing downwards the upper machine base.

Description

Capper

The utility model relates to a kind of closing device, especially for the capper of plastic film envelope.

Sealing generally by manual of plastic film bag finished, and is about to the preheating ironmongery and places sack to make the local heat seal of film and reach and seal purpose.This method is troublesome poeration not only, and efficient is low.

The purpose of this utility model just provides a kind of easy and simple to handle and capper that efficient is higher.

The technical solution of the utility model is a kind of capper, comprises upper frame and the lower support that connects with the upper frame activity, is provided with pull back spring between upper frame, the lower support, and its key is that upper frame, lower support end are provided with last gear piece and the following gear piece that is meshed.

And upper and lower gear piece is the driven gear and the driving gear that can rotate around the axle center, and driving gear connects with miniature motor on being located at support.

And support is provided with the pressure that connects motor and power supply and touches switch, presses to touch switch and press sheet and be located at the power contact that presses under the sheet and constitute by being located at elasticity that pull back spring bottom and motor electrically connect.

And at least one is the double rows of teeth gear piece for the mating teeth sheet.

The utility model is owing to adopt this support to be provided with the capper of gear piece, and during operation, hand-held capper or put capper on bench board overs sack on the lower support gear piece, and energized also presses down upper frame and can make sack heat seal sealing by fusing.Therefore the utility model is easy to operate, efficient is high.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the capper structural representation that the utlity model has the hot pressing gear;

Fig. 2 is the capper structural representation that the utlity model has the hot pressing gear piece;

Fig. 3 is a scheme drawing of going up gear piece among Fig. 2;

Fig. 4 is the scheme drawing of following gear piece among Fig. 2;

Fig. 5 is the enlarged drawing of electric heating gear mounting structure among Fig. 1.

Referring to Fig. 1, Fig. 2, capper of the present utility model comprises upper frame 4 and lower support 1, upper frame 4 and lower support 1 afterbody are hinged by pin 7, head is provided with mating teeth shape heating plate 2,3,11,12, support 4 is provided with the switch 5 that connects profile of tooth heating plate 3,12 and power supply, is connected with between the upper and lower support to reset after pull back spring 6 presses down with control upper frame 4.Profile of tooth heating plate of the present utility model can be selected following several scheme:

Scheme one, described as shown in Figure 2 profile of tooth heating plate are last gear piece 12 and the following gear piece 11 that is meshed.Last gear piece 12 is strap saw shape (see figure 3), by electrothermal layer with cover profile of tooth heat transfer layer on it and constitute or directly make with thermo electric material, its electrode by switch 5 with exchange or direct supply joins, following gear piece 11 is the ribbon (see figure 4), surface distribution has and last gear piece 12 mating teeth lines.

Scheme two, referring to Fig. 1, described profile of tooth heating plate is the driving gear 2 and the driven gear 3 that can rotate around its axle center.Driven gear 3 is the electric heating gear, as shown in Figure 5, electric heating gear 3 is by fluted disc 14 and be located at the heating layer that is formed by thermo electric materials such as resistor wire or PTC electric heating elements 18 on the fluted disc 14 and cover single row or multiple rows heat transfer tooth 16 on the heating layer 18 (Fig. 5 provide be the double rows of teeth structure), electric heating gear 3 13 connects with axle on being fixed on upper frame 4 by bearing, gear 3 two sides are provided with and exchange or the two poles of the earth friction lining 15 of direct supply, they be fixed on axle 13 or the support 4 and with the two poles of the earth 17 (reed or elasticity are bumped pearl) wipe contact of the heating layer 18 of electric heating gear 3.The driving gear 2 that is located on the lower support 1 is driven by miniature motor 10, lower support 1 is provided with the pressure that connects motor 10 and direct current or source of AC and touches switch, presses to touch that switch presses steel disc 9 by the elasticity that electrically connects with motor that is located at pull back spring 6 bottoms and the power contact 8 that is located under the steel disc 9 constitutes.During operation, the plastics sack is placed between the driving and driven gear, the source switch 5 of opening electric heating gear 3 makes gear 3 preheatings, and press down upper frame 4, the pull back spring pressurized makes elasticity press steel disc 9 and contacts energising with power contact 8, motor 10 starts and also drives driving gear 2 rotations, and when driving and driven gear mesh rotates and to wait to seal line pressure along sack out-of-date, part in compression is promptly by heat seal.Therefore adopt this structure, the utility model can not be subjected to the restriction of involution length to any plastic sheeting sack involution.

Scheme three can change the monorow tooth on the profile of tooth heating plate in scheme one, the scheme two 12,3 and is made as double rows of teeth 16, and the crown of two toothrows, tooth mouth preferably are staggered.Can obtain better sealing effect like this.

For control profile of tooth heating plate heating-up temperature, can on the capper of such scheme, add coolant-temperature switch.
