Description

Improved reverse coating device for rubber paste

The technical field is as follows:

the utility model relates to a rubber paste production technical field, concretely relates to reverse coating unit of modified rubber paste.

Background art:

in the technology of producing rubber paste, a coating machine is one of core production devices, the traditional coating process generally uniformly coats the paste on the adhesive plaster, and then covers the plastic paper, but the coating mode has strict requirements on the elasticity of coating, the product quality is reduced due to the fact that the paste is easily unevenly coated due to the elasticity of the adhesive plaster, the improved coating machine generally coats the paste on the plastic paper, then the adhesive plaster can be effectively prevented from deforming when the adhesive plaster is covered (namely, a reverse coating process), and then the final product is formed by extrusion, bonding, drying and slicing, the existing coating machine generally generates hot air through a heating wire and a fan, and then the hot air is sprayed on the surface of the rubber paste for drying, and the drying mode has the following defects: 1. hot air is blown to the surface of the rubber paste, so that the paste is easy to blow away, and the paste is unevenly distributed on the adhesive plaster; 2. the hot air heats the rubber paste on one side, resulting in low drying efficiency.

The utility model has the following contents:

an object of the utility model is to provide a modified rubber paste reverse coating device.

The content of the utility model is as follows: the utility model provides a modified rubber paste reverse coating device, its includes the reverse coating box that the level set up, along installing of length direction equipartition in the reverse coating box a plurality of to the squeeze roll wheel, be provided with paste subsides between the squeeze roll wheel, it still includes from a left side to the U-shaped heat pipe of right equipartition range, all the heat pipe all is linked together with the intake pipe, the intake pipe is linked together with inlet manifold, inlet manifold passes behind the reverse coating box with the electric heating coil pipe box is linked together, install the heating wire in the electric heating coil pipe box, the electric heating coil pipe box is connected with the fan on the heat pipe about the symmetrical division of paste has the taper hole sliding plug has the taper plug in the taper hole vertical fixedly connected with connecting rod on the taper plug, the other end fixedly connected with limiting plate of connecting rod the cover is equipped with compression spring on the connecting rod, one end of the compression spring is in contact with the limiting plate, the other end of the compression spring is in contact with the conical plug, and the compression spring, the connecting rod and the limiting plate are located in the heat pipe.

Furthermore, an exhaust pipe is arranged at the top end of the reverse coating box body.

The utility model has the advantages that: the utility model has simple structure, and the hot air is blown from the upper part and the lower part of the rubber paste simultaneously through the actual U-shaped heat pipe, thereby effectively improving the drying efficiency; set up elastic awl stopper device in hot-blast taper hole position, avoid hot-blast concentration, the direct surface that blows the rubber paste, the hot-blast area of heating that can effectual equipartition reduces the impact force of heat branch, avoids the ointment to distribute inhomogeneous the while on the adhesive tape to improve hot-blast utilization ratio.

Description of the drawings:

fig. 1 is a schematic view of the internal structure of the present invention;

FIG. 2 is a perspective view of the heat pipe of the present invention;

FIG. 3 is a perspective view of the heat pipe of the present invention;

FIG. 4 is an enlarged view of part A of FIG. 3;

in the figure, a reverse coating box body 1, an extrusion roller 2, a paste 3, a heat pipe 4, an air inlet pipe 5, an air inlet main pipe 6, a electrothermal coil pipe box body 7, a fan 8, a conical plug 9, a connecting rod 10, a limiting plate 11, a compression spring 12 and an exhaust pipe 13.

The specific implementation mode is as follows:

as shown in fig. 1 to 4, an improved reverse coating device for rubber paste comprises a horizontally arranged reverse coating box 1, a plurality of pairs of squeeze rollers 2 are uniformly arranged in the reverse coating box 1 along the length direction, paste pastes 3 are arranged between the squeeze rollers 2, the device further comprises U-shaped heat pipes 4 uniformly arranged from left to right, all the heat pipes 4 are communicated with an air inlet pipe 5, the air inlet pipe 5 is communicated with an air inlet header pipe 6, the air inlet header pipe 6 penetrates through the reverse coating box 1 and then is communicated with a electrothermal coil box 7, heating wires are arranged in the electrothermal coil box 7, the electrothermal coil box 7 is connected with a fan 8, tapered holes are symmetrically formed on the heat pipes 4 relative to the paste 3, tapered plugs 9 are plugged in the tapered holes, connecting rods 10 are vertically and fixedly connected to the tapered plugs 9, a limiting plate 11 is fixedly connected to the other end of the connecting rod 10, a compression spring 12 is sleeved on the connecting rod 10, one end of the compression spring 12 is in contact with the limiting plate 11, the other end of the compression spring 12 is in contact with the conical plug 9, and the compression spring 12, the connecting rod 10 and the limiting plate 11 are located in the heat pipe 4; further, an exhaust pipe 13 is attached to the top end of the reverse coating tank 1.
