Description

A kind of roll coater applicator roll

Technical field

The present invention relates to a kind of roll coater parts, relate in particular to a kind of roll coater applicator roll.

Background technology

Existing roll coater complete machine divides two parts substantially: top melten gel gluing part and lower chain roller transport portion, melten gel and gluing are mainly that the applicator roll heating by use completes, the inner mode of heating of the general roller adopting of heating of existing applicator roll, and the inner mode of heating of roller is due to excess Temperature in roller, heating element heater heat radiation is difficult for, heating element heater is fragile, difficult in maintenance, existing also have an external heat of employing, generally to applicator roll heat conduction by two ends, or by heat-conducting medium to the heat conduction of applicator roll center, these heat-conducting modes are because heat conduction position relationship can cause applicator roll surface temperature inhomogeneous, or it is on the low side to transmit heat to applicator roll when surface temperature, loses heat is large, cost is high.

Summary of the invention

For solving the problems of the technologies described above, the present invention has designed a kind of roll coater applicator roll.

The present invention adopts following technical scheme:

A kind of roll coater applicator roll, comprise roll body, roll body comprises roller shell and roller core, socket mutually between roller shell and roller core, the through of roller core forms central passage, roller core outer surface is provided with multispiral screw thread, the outer surface of roller core coordinates the many helical ducts of formation with the inner surface of roller shell, one end of described roll body is provided with ingress pipe and efferent duct, ingress pipe and efferent duct are concentric tube, in ingress pipe, it is input channel, between ingress pipe and efferent duct, form output channel, input channel is communicated with central passage, output channel is communicated with many helical ducts, the other end of roll body is provided with connector, connector is communicated with central passage and many helical ducts. this roll coater applicator roll adopts firing equipment at machine exterior independent heating, by heat-conducting medium, applicator roll is heated, thermal source is stablized easy to operate, and the through of roller core forms central passage, the outer surface of roller core coordinates the many helical ducts of formation with the inner surface of roller shell, heat medium (conduction oil) is by many helical duct circulation heat conduction on bears against roll shell surface, make the surface heated temperature of roller shell even, difference variation is little everywhere, greatly promote the quality of roll coater roller coat, heat medium bears against roll shell surface heat transfer, heat-transfer rate is fast, the heat of loss is few, cost-saving.

As preferably, described roller shell is coated with one deck antiadhesion barrier. The material binding that prevents roller coat by antiadhesion barrier gets on not down at roller shell.

As preferably, the multispiral screw thread of described roller core outer surface setting is bifilar helix screw thread, and the outer surface of roller core coordinates with the inner surface of roller shell and forms double helix passage, and connector is three-way connection, and three-way connection is communicated with central passage and double helix passage. Adopt double helix passage, Double-wire ring carries out heat conduction around pair roller shell surface, makes the surface heated temperature of roller shell even, and difference variation is little everywhere, and heat-transfer rate is fast.

As preferably, described ingress pipe end is connected with heat medium input pipe, and efferent duct end is connected with heat medium efferent duct. Facilitate heat medium circulation input and output by heat medium input pipe and heat medium efferent duct.

As preferably, described roll body two ends are respectively arranged with seal cover. Prevent that by this structure heat-conducting medium from overflowing, and reduce thermal loss.

The invention has the beneficial effects as follows: by this roll coater applicator roll heat conduction, make the surface heated temperature of roller shell even, difference variation is little everywhere, greatly promote the quality of roll coater roller coat, heat medium bears against roll shell surface heat transfer, heat-transfer rate is fast, the heat of loss is few, cost-saving.

Detailed description of the invention

Below by specific embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is further described specifically:

Embodiment: as accompanying drawing 1, accompanying drawing 2, shown in accompanying drawing 3 and accompanying drawing 4, a kind of roll coater applicator roll, comprise roll body 1, roll body comprises roller shell 2 and roller core 3, socket mutually between roller shell and roller core, the through of roller core forms central passage 4, roller core outer surface is provided with bifilar helix screw thread, the outer surface of roller core coordinates formation double helix passage 7 with the inner surface of roller shell, one end of described roll body is provided with ingress pipe 8 and efferent duct 9, ingress pipe and efferent duct are concentric tube, in ingress pipe, it is input channel 10, between ingress pipe and efferent duct, form output channel 11, input channel is communicated with central passage, output channel is communicated with double helix passage, the other end of roll body is provided with connector 12, connector is three-way connection, three-way connection is communicated with central passage and double helix passage, roller shell is coated with one deck antiadhesion barrier, ingress pipe end is connected with heat medium input pipe 5, efferent duct end is connected with heat medium efferent duct 6, roll body two ends are respectively arranged with seal cover.

When this roll coater applicator roll uses, heat medium is inputted from heat medium input pipe, heat medium is successively by ingress pipe and central passage, finally by double helix passage and efferent duct, to a circulation of heat medium efferent duct output formation, by outside heat medium, applicator roll is heated, thermal source is stablized easy to operate, when heat medium circulates heat conduction by the double helix passage on bears against roll shell surface, make the surface heated temperature of roller shell even, difference variation is little everywhere, greatly promote the quality of roll coater roller coat, heat medium bears against roll shell surface heat transfer, heat-transfer rate is fast, the heat of loss is few, cost-saving.

Above-described embodiment is preferably scheme of one of the present invention, not the present invention is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim records.
