Problems solved by technology

After extensive research, it is found that the current general-purpose drive shaft is directly inserted into the aluminum tube with a polymer tube. The friction coefficient between the aluminum tube and the rubber tube is low, and the friction force is small. Although the rubber tube and the aluminum tube are tightly fitted, the rubber tube has a certain shrinkage ratio. , but the surface friction coefficient of the aluminum tube is very low, about 0.4. If the driving force is increased, it will be greater than the friction between the aluminum tube and the rubber tube, and slippage will occur
If the aluminum tube and the rubber tube slip, the rubber tube may deviate or shrink

Embodiment 1

[0053] In this embodiment, the anti-skid drive shaft structure includes the following manufacturing process:

[0054] The first step, the production of the outermost polymer elastic layer rubber hose: the material can be EPDM as the main material. This embodiment uses 100 parts of Shanghai Mitsui EPDM3072EM, 40 parts of carbon black reinforcing agent, 40 parts of conductive carbon black, zinc oxide 5 parts, 1 part of stearic acid, 1.5 parts of dispersant, 0.2 parts of anti-scorch agent, 1.5 parts of sulfur and 44 parts of EG-44, blended together to form a rubber compound. The refined mixed rubber is put into the extruder equipped with a T-head extruder, such as Figure 4 As shown in the schematic diagram, the 4-02 transition mandrel is inserted into the T-shaped head 4-03 installed on the extruder 4-01, and the transition mandrel is inserted from the upper hole, and the extruder 4-01 extrudes The rubber bag is attached to 4-02 and extruded from the lower hole of the T-shaped ...

Embodiment 2

[0061] In this embodiment, the anti-skid drive shaft structure includes the following manufacturing process:

[0062] Its formula of present embodiment is the same as embodiment 1, and only technological process is different.

[0063] The first step and the second step are made of EPDM material rubber hose according to embodiment 1, and the glue is made.

[0064] The third step is to process the composite adhesive layer of the aluminum tube. The aluminum tube is a purchased product with an outer diameter of 23.5 mm. Surface degreasing and cleaning. Apply the primer layer CH205, air-dry, apply the transition adhesive layer adhesive CH238, air-dry, apply the glue layer, bake and dry at 40°C for 30 minutes.

[0065] The fourth step is to assemble the rubber tube and the aluminum tube. The rubber tube prepared in the first step and the aluminum tube processed in the third step are inflated and inserted on the aluminum tube with a special blower fixture. The shape is tightly matc...

Embodiment 3

[0070] In this embodiment, the anti-skid drive shaft structure includes the following manufacturing process:

[0071] The first step is the production of the outermost polymer elastic layer hose. The material is NBR / ECO as the main material. In this embodiment, JSR NBR230S, Dacao ECO CG102, 70 parts of NBR250SL, 30 parts of ECO, 5 parts of zinc oxide, hard 1 part of zinc ester, 33 parts of white carbon black reinforcing agent, 24 parts of weakly conductive carbon black, 1 part of dispersant, 0.6 part of sulfur, 2 parts of CZ, 1.8 parts of TT, compounded and kneaded into a rubber compound. The refined mixed rubber is put into the extruder equipped with T-shaped head for extrusion, and at the same time, the transition mandrel is cast on the upper side of the T-shaped head, and the rubber hose package is attached to the transition mandrel and slides out from the lower side of the T-shaped head ( see Figure 4 ), the NBR / ECO rubber hose attached to the transition mandrel is place...

Abstract

The invention discloses an anti-skid driving shaft structure applied to a color printer. The anti-skid driving shaft structure comprises an aluminum pipe, a rubber pipe and a composite adhesive layerfor bonding the aluminum pipe and the rubber pipe together, wherein the composite adhesive layer comprises a bottom coating, a transition adhesive layer and a mucilage layer; the bottom coating is chemically bonded with the surface of the aluminum pipe and tightly adheres to the aluminum pipe; the transition adhesive layer is composed of a polymer elastomer and a solvent; and the mucilage layer isused for being heated and adhering to the rubber pipe, so that the rubber pipe and the aluminum pipe attached to the composite adhesive layer are tightly matched or tightly matched and bonded in a chemical bond crosslinking mode. According to the anti-skid driving shaft structure, the aluminum pipe is coated with the composite adhesive layer tightly bonded with the aluminum pipe, and the composite adhesive layer and the aluminum pipe are bonded in a chemical bond combination mode; the rubber pipe composed of the polymer elastomer is arranged on the outermost layer, and the composite adhesivelayer is the polymer elastomer with electrical conductivity and can be conveniently compounded with the rubber pipe; and finally, the rubber pipe and the aluminum pipe attached to the composite adhesive layer are tightly matched or tightly matched and bonded in the chemical bond crosslinking mode, so that the aluminum pipe and the rubber pipe form a whole through the composite adhesive layer, andthe friction force of the anti-skid driving shaft structure is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of transfer structures of color printers and color copiers, and in particular relates to a transfer belt and a mechanism for driving the transfer belt to rotate when the color toner of a color printer and copier is transferred. Background technique [0002] Nowadays, with the rapid development of color printing and copying technology, the printing speed is also continuously improved, and the driving force is increased. The existing drive shaft often has problems such as slippage of the rubber tube sleeved on the aluminum tube, deviation of the rubber tube, and shrinkage. After extensive research, it is found that the current general-purpose drive shaft is directly inserted into the aluminum tube with a polymer tube. The friction coefficient between the aluminum tube and the rubber tube is low, and the friction force is small. Although the rubber tube and the aluminum tube are tightly fitted, the rubber tube h...
