Description
Technical field
The present invention relates to stylus printer more particularly to a kind of printer pickup rollers.
Background technique
Printer pickup roller plays a significant role the stabilization of printer routine work, paper feeding as paper pushing part is realized
The height of efficiency determines the efficiency of printer operation.Existing feeding-in roll is that rubber layer composition is arranged on roll shaft.It is existing
Rubber layer is set on roll shaft and is only fixed with crosslinking agent between roll shaft, since the working environment of pickup roller is hot and cold alternation
Environment, so opposite slide can occur between rubber layer and roll shaft after a period of operation for pickup roller.The rubber layer of pickup roller
Friction generates heat between paper at work, and the heat of accumulation leads to rubber layer temperature distortion.The phase of rubber layer and roll shaft
The stability of pickup roller paper feeding can be all seriously affected to the deformation of sliding and rubber layer, or even paper jam occurs.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of printer pickup roller, solves pickup roller in the prior art and exist
The problem of opposite sliding and rubber layer are vulnerable to thermal deformation can occur between rubber layer and roll shaft after a period of work.
The technical solution adopted by the present invention to solve the technical problems is: a kind of printer pickup roller, including roll shaft, described
Symmetrical affixed two block baffle on the outside of roll shaft, the baffle are ring structure, and baffle protrusion is arranged in border, and cylinder is fixed in two pieces
Between baffle, the material of the cylinder is solid heat conductive material, and the setting of cylinder border and the cylinder that baffle protrusion matches are raised,
Baffle is sealed with roll shaft junction and cylinder with baffle junction, and roll shaft, cylinder and baffle, which enclose, is set as closed cooling chamber, cold
Intracavitary filling coolant liquid, cylindrical outer are arranged rubber layer, crosslinking agent, the rubber layer are coated between the cylinder and rubber layer
Inner wall be provided with the corresponding rubber layer groove of cylinder protrusion, the rubber layer outer surface is rough surface, rough surface
Degree is 15~35 μm.
Further, the roll shaft is solid metal material.
Further, the baffle is welded on roll shaft.
Further, the baffle protrusion is rectangle, and quantity is four and using roll shaft as symmetrical centre circular array
Uniformly arrangement.
Further, the cylinder both ends and baffle weld.
Further, the coolant liquid filled in the cooling chamber is glycol-cooled liquid.
The invention has the following beneficial effects: welded on roll shaft two block baffles and by cylinder welding two block baffles it
Between, this be equivalent to realize it is affixed between roll shaft and cylinder, due to the border of cylinder setting cylinder protrusion and in rubber
The inner wall setting rubber layer groove corresponding with cylinder protrusion of layer, so it is solid not only rely on crosslinking agent between rubber layer and cylinder
Fixed, the cooperation positioning action of cylinder protrusion and rubber layer groove can also limit sliding of the rubber layer relative to cylinder, guarantee rubber
Glue-line and cylinder it is affixed.A closed cooling chamber has been set and in cooling chamber due to enclosing between roll shaft, cylinder and baffle
Coolant liquid is filled, so the heat for the generation that rubs between rubber layer and paper can pass through solid heat conductive material when pickup roller works
Manufactured cylinder passes to the coolant liquid in cooling chamber, and coolant liquid absorbs and store heat, prevents rubber layer temperature distortion.In this way
The stability of pickup roller paper feeding improves, more will not there is a situation where paper jams.
Detailed description of the invention
Fig. 1 is sectional view along AA in Fig. 2；
Fig. 2 is front view of the present invention；
Fig. 3 is side view of the present invention.
Specific embodiment
As shown in Figure 1,2 and 3, a kind of printer pickup roller, including roll shaft 1, the symmetrical affixed two pieces of gears in 1 outside of roll shaft
Plate 5, the baffle 5 are ring structure, and baffle protrusion 51 is arranged in border, and cylinder 3 is fixed between two block baffles 5, the circle
The material of cylinder 3 is solid heat conductive material, the cylinder protrusion 31 that the setting of 3 border of cylinder matches with baffle protrusion 51, baffle 5 and roller
1 junction of axis and cylinder 3 are sealed with 5 junction of baffle, and roll shaft 1, cylinder 3 and baffle 5, which enclose, is set as closed cooling chamber 2, cold
But coolant liquid is filled in chamber 2, and rubber layer 4 is set outside cylinder 3, is coated with crosslinking agent between the cylinder 3 and rubber layer 4, it is described
The inner wall of rubber layer 4 be provided with the raised 31 corresponding rubber layer grooves 41 of cylinder, 4 outer surface of rubber layer is coarse table
Face, surface roughness are 15~35 μm.The roll shaft 1 is solid metal material.The baffle 5 is welded on roll shaft 1.It is described
Baffle protrusion 51 is rectangle, and quantity is four and is that symmetrical centre circular array is uniformly arranged with roll shaft 1.The cylinder 3
Both ends and baffle 5 weld.The coolant liquid filled in the cooling chamber 2 is glycol-cooled liquid.
When the invention works, roll shaft 1 drives cylinder 3 to move by baffle 5, due to being coated with friendship between cylinder 3 and rubber layer 4
Connection agent and the outside that cylinder 3 is fixed in by cylinder protrusion 31 and the guarantee of rubber layer groove 41 rubber layer 4,1 rotation process of roll shaft
Middle rubber layer 4 will not be produced relative sliding with cylinder 3.In the pickup roller course of work, friction is generated between rubber layer 4 and paper
Heat cylinder 3 made of solid heat conductive material passes to the coolant liquid in cooling chamber 2, and coolant liquid absorbs and stores heat
Amount, prevents 4 temperature distortion of rubber layer.The stability of pickup roller paper feeding improves in this way, more will not there is a situation where paper jams.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form, appoint
What those skilled in the art, without departing from the scope of the present invention, when in the technology using the disclosure above
Hold the equivalent embodiment for being modified or being modified to equivalent variations, but without departing from the technical solutions of the present invention, according to
According to technical spirit of the invention, within the spirit and principles in the present invention, it is to the above embodiments it is any it is simple modification,
Equivalent replacement and improve etc., fall within the scope of protection of the technical scheme of the present invention within.
