The single spreading machine
Technical field
The utility model relates to the glue application device technology of nonwoven.
Background technology
Existing nonwoven gluing all is the impregnation formula, behind shredding, combing, one-tenth net, and impregnation, the rolling of drying again, cut edge.This impregnation equipment comes down to a glue cylinder, the work glue that mixes up is poured in the glue cylinder, semi-finished product into the net soak in the glue from work with certain linear velocity and drag and mistake, again through paired pressure roller extruding, work glue inwardly infiltrates from two appearances up and down, makes whole nonwoven obtain uniform glue on thickness direction.
Along with the diversity of nonwoven product, people need a kind of two-sided have different hardness, different flexibility, different flexible sanding felt, and this sanding felt simultaneously has colloid, and another side does not have colloid.If with the impregnation equipment of prior art, then can not produce the product of design.
The utility model content
The purpose of this utility model is to have colloid for producing one side, and another side does not have a kind of glue spreader of realizing single spreading of the supporting design of sanding felt of colloid or less colloid.
The utility model mainly is made up of frame, motor, speed changer, drive roll, driven voller, glue groove, scraper, drive roll, driven voller respectively by bearings on frame, one end of drive roll is connected with motor by speed changer, driven voller is arranged in the below of drive roll, axially being parallel to each other of driven voller and drive roll, plastic tank is established in the place ahead at drive roll, connects scraper on the glue groove of drive roll relatively.
Semi-finished product into the net are passed by from level between drive roll, the driven voller, work glue by the glue groove be poured on downwards half-finished above, the spacing on scraper and drive roll surface then is the suitable glue-spread of control, extruding through drive roll, driven voller, work glue is by an endosmosis, and another side or do not have glue, or have only a spot of glue, realize single spreading with this.The utility model is simple and reasonable for structure, and production cost is low, and is easy to operate.
In addition, the bearing that the utility model connects driven voller is connected connecting rod, and connecting rod connects a vertical screw rod of arranging, screw flight is connected on the frame.Can be by the cooperating of screw thread on screw rod and the frame, change the spacing of driven voller and drive roll, to control spread.
The glue groove is connected on the frame by connecting screw rod, described connecting screw rod lateral arrangement.By the adjusting of connecting screw rod, make the spacing of the scraper of glue front of the slot and drive roll adjusted.
In order to make work glue unnecessary in the glue groove not produce waste, the utility model also is provided with surplus glue groove below the glue groove.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in the figure, the utility model mainly is made up of frame 4, motor 14, speed changer 13, drive roll 5, driven voller 9, glue groove 6, scraper 7.Connect drive roll 5 by pair of bearings on a crossbeam of frame 4, an end of drive roll 5 is connected with motor 14 by chain connecting gear 12, speed changer 13.A connecting rod 15 is arranged in parallel under the crossbeam of frame 4, the connecting rod 15 welding one vertical screw rod of arranging 2, screw rod 2 is threaded in the vertical screw 3 on frame 4 crossbeams, the upper end of screw rod 2 connects handwheel 1, the other end of connecting rod 15 is provided with bearing 10, in order to supporting driven voller 9, and make driven voller 9 be arranged in the below of drive roll 5, axially being parallel to each other of driven voller 9 and drive roll 5.
The place ahead at drive roll 5 connects glue groove 6, connecting screw rod 8 lateral arrangement by connecting screw rod 8.Disjunctor is provided with scraper 7 on the glue groove 6 of drive roll 5 relatively.
Surplus glue groove 11 is set below glue groove 6.
Among Fig. 1 16 is nonwoven semi-finished product into the net.
