Abstract
The invention relates to a mechanism, which is applied to automatic labeling equipment for mobile phones and various digital products, adopts a cam to control a disc feeding label in a controllable friction manner during a high-speed and intermittent motion process and is capable of automatically realizing a constant tension. The mechanism comprises a rocker arm, a semicircular damping hoof block, a friction block, a driven shaft, a cam and a spring. During a working process, a feeding loading belt wound on a material-receiving plate is tightened while coming round the rocker arm and the cam fixedly connected to the rocker arm is driven to rotate by the rocker arm, thereby opening the semicircular damping hoof block, reducing a frictional force between the semicircular damping hoof block and the driven shaft and loosening the feeding loading belt. After the feeding loading belt is loosened, a torque of a cam axis is reduced by the rocker arm, thereby increasing the frictional force between the semicircular damping hoof block and the driven shaft and tightening the feeding loading belt again. A dynamic balance of the tension of the feeding loading belt and the frictional force between the semicircular damping hoof block and the driven shaft is utilized to keep a constant tension state of the feeding loading belt.
Description
Affiliated technical field:
The present invention is on a kind of automatic labeling apparatus that is applied in mobile phone and all kinds of digital products, adopts the mode of controlled friction, at a high speed, in the intermittent moment process, the label that adopts the plate-like feed by cam-controlled, is realized the mechanism of permanent tension force automatically.
Background technology:
For realizing all kinds of technological requirements, need paste like multiple films such as conductive rubber, protective film, adhesive tape, Acrylic Foam Tape, protection foams and cut part in the electronic machine of mobile phone and all kinds of digital product and automobile.It is many by manual completion to paste technology, inefficiency not only, and because simple the repetition, so quality also is difficult for assurance.For solving this type problem, gradually adopted automated tag to paste equipment at present.But all kinds of labels equipment that pastes all adopts at a high speed, intermittently supplies label form, and then the cutting part label just will produce violent speed fluctuations with plate-like feed carrier band, thereby cause the tension force of feed carrier band also to have greatly changed.The permanent tension control mechanism of friction-type provided by the invention can be realized feed carrier band constant-tension through the mode of cam automatic guidance friction, reaches and improves the purpose that label pastes quality.
Summary of the invention:
Automatically labeling apparatus is in order to realize at a high speed, and the label that makes the plate-like feed can be realized permanent tension force automatically in the intermittence feeder process, can satisfy the increasingly high requirement that pastes with it.The invention provides a kind of permanent tension control mechanism of friction-type that constitutes by rocking arm, semicircle damping hoof piece, friction shoe, driven shaft, cam, spring etc.The core component of this separation device---two semicircle damping hoof pieces are under the combined action of spring and cam; Utilize the friction force controlling diaphragm to cut the damping moment of part supply disk; The cam rotation leans on the tension force of feed carrier band to drive; Utilize the dynamical equilibrium of friction force between tension force and the damping hoof piece and the driven shaft of feed carrier band, make the feed carrier band keep permanent tension state.
Technical scheme:
Film is cut part supply disk tensioner on the driven shaft of permanent tension control mechanism, and two semicircle damping hoof pieces frictionally under the effect of spring pins driven shaft.During work, driven by servomotor rewinding dish rotates, and the feed carrier band that twines on the rewinding dish is tightened when walking around rocking arm; And moment of rotation of camshaft generation to connecting firmly with it; The power cam rotation, thus semicircle damping hoof piece is opened, and friction force diminishes between driven shaft.Driven shaft and film cut the part supply disk be tensioner together, and co-rotational, so the feed carrier band will be become slack, then rocking arm drives camshaft line to counter-rotation, makes that friction force becomes big between damping hoof piece and driven shaft, the feed carrier band is tensioned again.Utilize the dynamical equilibrium of friction force between tension force and the damping hoof piece and the driven shaft of feed carrier band, make the feed carrier band keep permanent tension state.
The invention has the beneficial effects as follows:
The present invention is on a kind of automatic labeling apparatus that is applied in mobile phone and all kinds of digital products, adopts the mode of controlled friction, at a high speed, in the intermittent moment process, the mechanism that makes the label that adopts the plate-like feed can realize permanent tension force automatically.Can realize feed carrier band constant-tension through the mode of cam automatic guidance friction, reach and improve the purpose that label pastes quality.

The specific embodiment:
As shown in Figure 1, film is cut part supply disk tensioner on the driven shaft (4) of permanent tension control mechanism, and two semicircle damping hoof pieces (2) frictionally under the effect of spring (6) pins driven shaft (4).During work, driven by servomotor rewinding dish rotates, and the feed carrier band (7) that twines on the rewinding dish is tightened when walking around rocking arm (1); Then cam (5) axis that connects firmly with it is produced a moment of rotation through rocking arm (1), power cam (5) rotation, thus semicircle damping hoof piece (2) is opened; And friction force diminishes between driven shaft (4); Driven shaft (4) and film are cut part supply disk tensioner together and co-rotation, so feed carrier band (7) will be become slack, then rocking arm (1) drive cam (5) axis is to counter-rotation; Make between damping hoof piece (2) and driven shaft (4) friction force become big, feed carrier band (7) is tensioned again.Utilize the dynamical equilibrium of friction force between tension force and the damping hoof piece (2) and the driven shaft (4) of feed carrier band (7), make feed carrier band (7) keep permanent tension state.
