100 material belt feeding rollers, 210 hanging guide rollers, 220 feeding guide rollers, 300 counterweight tensioning rollers, 310 counterweight rollers, 320 limit protrusions, 330 counterweight travel spaces, 400 sensors and 500 material belts.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
the material belt discharging mechanism, as shown in figure 1, comprises
A tape feed roller 100 for providing a tape spool, a tape 500 of the tape spool extending outwardly,
the hanging guide roller 210 is rotatably provided to the frame, the material tape output from the material tape feeding roller 100 is hung on the upper side of the hanging guide roller 210,
a weight tension roller 300 which is pressed against the upper side of the material belt 500 between the material belt feeding roller 100 and the hanging guide roller 210; wherein, in the working state, the control device comprises a control device,
the press-fit surface of the weight tensioning roller 300 is maintained below the level of the guide surface of the hanger guide roller 210. So that the counterweight tension roller 300 can be kept pressed against the material belt.
When the weight tension roller 300 presses down the material belt 500, the material belt 500 downstream of the weight tension roller 300 is wound around the hanging guide roller 210, and the guiding of the movement of the material belt 500 is achieved by the hanging guide roller 210, so that the material belt 500 is prevented from being excessively pulled down by the weight tension roller 300.
As shown in fig. 3, the material tape feed roller 100 is rotatably provided to a frame, and the material tape feed roller 100 has a feed roller driving assembly; the upstream side of the hanging guide roller 210 is provided with a weight running space 330, and the weight tension roller 300 moves up and down in the weight running space 330.
In many cases, the counterweight tensioning roller 300 moves up and down in the counterweight travel space as the tightness of the belt changes. For example, when the material belt between the material belt feeding roller 100 and the hanging guide roller 210 is long, the weight tensioning roller 300 moves downward to press the material belt downward so that the material belt is tensioned; when the web between the web feeding roller 100 and the hanging guide roller 210 is short, the weight tension roller 300 still keeps pressing down the web, but at this time, the position of the weight tension roller 300 is high.
As shown in the drawing, an inductor 400 is provided at the upper side of the weight path space 330, and the feed roller driving assembly drives the material tape feed roller 100 to rotate or accelerate the rotation feed when the weight tension roller 300 moves to the detection position of the inductor 400.
The inductor 400 is mainly used for sensing whether the height of the counterweight tensioning roller 300 reaches the highest limit, and when the position of the counterweight tensioning roller 300 reaches the highest limit, the material belt between the material belt feeding roller 100 and the hanging guide roller 210 is too short, and the material belt length between the two needs to be increased at this time, and the main means for increasing the material belt length is to control the feeding speed of the material belt feeding roller 100 in the direction. If the raw material belt feeding roller 100 does not rotate, the raw material belt feeding roller can be controlled to rotate to accelerate feeding; if the web feed roller 100 is feeding at a constant speed, the controller accelerates the feeding for a period of time (e.g., 2-5S) to increase web redundancy of the web feed roller 100 and the hanging guide roller 210. The sensor 400 and the driving component of the material belt feeding roller 100 can be connected with a control component, and the specific control coordination can directly adopt the prior art.
In order to better control the web redundancy of the web feed roller 100 and the hanging guide roller 210, it is generally necessary to control the feed rate in the direction of the web feed roller 100; the feeding roller driving assembly is a feeding roller driving motor for the material belt, and the rotating speed of the feeding roller driving motor for the material belt is adjustable.
The sensor 400 is a heavy tension roller height sensor, which can be flush with the highest limit, and when the counterweight tension roller 30 reaches the highest limit, the sensor 400 senses a signal, and detects that the counterweight tension roller 300 reaches the highest limit; or the sensor 400 can detect the height of the weight tensioning roller 300 in the whole process, no matter the height of the weight tensioning roller 300, a height signal can be generated, but only when the weight tensioning roller 300 reaches the highest limit, the action of the material belt feeding roller 100 can be coordinated.
As shown in fig. 2 to 3, a feeding guide roller 220 is further provided at the upstream side of the hanging guide roller 210, and the web fed from the web feeding roller 100 passes through the feeding guide roller 220 and the hanging guide roller 210 in this order.
The hanging guide roller 210 and the feeding guide roller 220 can adopt a rotary guide roller or a fixed guide roller, and the fixed guide roller cannot rotate.
The counterweight tensioning roller 300 is pressed on the upper side surface of the material belt 500 between the hanging guide roller 210 and the feeding guide roller 220; the counterweight traveling space 330 is located between the hanging guide roller 210 and the feed guide roller 220.
At this time, the material belts on the upper and lower sides of the counterweight tensioning roller 300 can be limited, so that the counterweight tensioning roller 300 is more stable and is not easy to swing when being used for pressing the material belts.
In the implementation process, in order to prevent the material belt from shifting on the hanging guide roller 210 and the feeding guide roller 220 and sliding off from the side, the end parts of the hanging guide roller 210 and the feeding guide roller 220 are provided with material belt limiting convex parts.
As shown in fig. 2, two ends of the weight roller 310 of the weight tensioning roller 300 are provided with limit protrusions 320; the two stopper protrusions 320 serve to restrict the material belt 500 from slipping off the balance weight roller 310.
The counterweight tensioning roller 300 may also be limited or have increased stability in other manners, such as sliding the two ends of the counterweight tensioning roller 300 on a longitudinal slide, where the longitudinal slide is located in the counterweight travel space 330. The weight tensioning roller 300 can move up and down along the longitudinal sliding piece, so that the weight tensioning roller 300 can keep pressing down on a material belt, and meanwhile, the weight tensioning roller 300 can be well stabilized.
It will be apparent to those skilled in the art that various modifications to the above embodiments may be made without departing from the general spirit and concepts of the utility model. Which fall within the scope of the present utility model. The protection scheme of the utility model is subject to the appended claims.
