Problems solved by technology

Because this kind of shrinking roller is formed by crushing waste cloth and mixing it with phenolic resin, and then extruding it on the outer circle of the roller core with a mold and a press, the texture of the outer circle is very irregular, not only the shrinking speed is slow, The efficiency is not high, and the thickness of the shrunk surface is very inconsistent, and the quality is poor

Embodiment 1

[0035] refer to figure 1 , figure 2 and combine image 3 , a shrinking roll of a shrinking machine, comprising a steel shaft 1 and a cast iron roll sleeve 2, the steel shaft 1 is axially installed in the cast iron roll sleeve 2, and the outer surface of the cast iron roll sleeve 2 is covered with a bonding layer 3; The surface of the layer 3 is covered with an adhesive layer 4; the thickness of the adhesive layer 4 is 1.2 to 2.3 cm; the outer surface of the cast iron roller sleeve 2 is provided with grooves 21; parallel.

Embodiment 2

[0037] refer to Figure 4 and combine Figure 5 , The feature of this embodiment is that the groove 21 is provided on the outer surface of the cast iron roller sleeve 2 in a spiral manner. All the other structures and features are the same as in Embodiment 1.

[0038] Through the setting of the groove 21, the adhesive layer 3 can be embedded in the cast iron roller sleeve 2 through the groove 21, so that the adhesive layer 4, the adhesive layer 3 and the cast iron roller sleeve 2 are integrated, so that the cast iron roller sleeve 2 passes through the groove 21 It can better grasp the adhesive layer 4 and maintain the stability of the adhesive layer 4, and when the shrinkage roll rotates, the groove 21 is conducive to providing a maintenance force for the adhesive layer 4, reducing the friction between the adhesive layer 4 and the cast iron roller sleeve 2 The displacement makes the shrinking rollers of the shrinking machine more durable. In Example 1, the groove 21 is set ...

Embodiment 3～5

[0040] Embodiment 3~5 prepares shrinking roll of shrinking machine by following preparation method:

[0041] A kind of preparation method of shrinking roll of shrinking machine as above, comprises the following steps:

[0042] 1) Installation: Install the shaft body in the sleeve;

[0043] 2) Finishing: Clean the residual glue and rust on the surface of the bushing, and then roughen the surface of the bushing;

[0044] 3) Cleaning: remove the impurities on the surface of the shaft sleeve, then clean with a cleaning agent and dry;

[0045] 4) Pretreatment: apply a metal surface treatment agent on the surface of the shaft sleeve;

[0046] 5) Gluing: After mixing the cold adhesive with the hardener, apply it on the surface of the shaft sleeve, and after curing under the condition of a pressure of 0.5-1.8MPa, apply a layer on the shaft sleeve, and also apply it on the surface of the adhesive layer. back;

[0047] Wherein, the formula of adhesive layer in embodiment 3~5 is as s...

Abstract

The invention discloses a fulling roller of a fulling machine and a preparation method of the fulling roller. The fulling roller of the fulling machine comprises a shaft body and a roller sleeve, wherein the shaft body penetrates into the roller sleeve along the axial direction; a bonding layer covers the outer surface of the roller sleeve; a glue layer covers the surface of the bonding layer; the thickness of the glue layer is 1.2cm to 2.3cm; the preparation method of the fulling roller comprises the following steps: 1) mounting: mounting the shaft body into a shaft sleeve; 2) finishing: cleaning the surface of the shaft sleeve; 3) washing: washing to remove impurities on the surface of the shaft sleeve; 4) pre-treating: coating a metal surface treatment agent on the surface of the shaft sleeve; 5) gluing: after mixing a cold adhesive with a hardening agent, coating on the surface of the shaft sleeve; after hardening, coating one layer again; meanwhile, coating on a back surface of the glue layer; 6) laminating: laminating a rubber plate on the surface of the shaft sleeve and compacting the glue layer on the shaft sleeve to obtain the fulling roller of the fulling machine. The fulling roller of the fulling machine, disclosed by the invention, has flat surface lines and a wear-resisting property; when the fulling roller of the fulling machine is repaired, the glue layer can be directly detached and replaced and the whole fulling roller does not need to be replaced.

Description

technical field [0001] The invention relates to a shrinking roll of a shrinking machine and a preparation method thereof, belonging to the technical field of textile processing equipment. Background technique [0002] It is known in the textile industry that after weaving worsted wool, carded wool, blended and knitted fabrics, they need to be shrunk to make the surface suede plump, elastic and feel good. The shrinking processing equipment used is a high-efficiency shrinking machine. The high-efficiency shrinking machine includes an upper shrinking roller and a lower shrinking roller, and a storage channel is provided on the exit side of the upper and lower shrinking rollers. When working, the shrunk material enters between the upper and lower shrinking rollers from the side away from the storage channel, is quickly squeezed by the upper and lower shrinking rollers, and then enters the storage channel, and is folded in an S shape in the storage channel and then is Pull it ou...
