Abstract
A kind of film delivery tension device, include the input roll shaft being arranged along conveying direction and output roll shaft, it is another to there is the tensioning holder of fixed setting and middle part to be articulated with the adjusting rod on tensioning holder, one end of adjusting rod is set between input roll shaft and output roll shaft and two or more adjusting roll shafts is housed thereon, the other end of adjusting rod is lifted with clump weight, and clump weight is more than the torque of hinge joint in the middle part of adjusting rod the torque that all adjusting roll shafts exchange hinge joint in the middle part of pole；Film alternately transfers to output roll shaft again after inputting roller bearing around all adjusting roll shafts.The structure of the film delivery tension device is extremely simple, but can effectively ensure that the conveying quality of film, to effectively simplify device structure, also reduces the requirement for making precision and work difficulty, while reducing production and maintenance cost.
Description
Technical field
The utility model is related to film conveying equipment, more particularly to being tensioned to film in a kind of conveying thin-film process
Device.
Background technology
Film is generally plastic material, with higher flexibility, and in modern automation production equipment, film it is steady
Conveying is particularly important component part calmly.In existing film conveying equipment, tension structure is generally by control system, driving electricity
Machine, pressure sensor and tensioning roll shaft composition detect pressure of the tensioning roll shaft between film using pressure sensor, then by controlling
System controls motor and drives tensioning roll shaft movement, to adjust pressure of the tensioning roll shaft to film.This kind of tension structure is complex,
Making precision and the operating accuracy requirement of equipment are all higher, and produce larger with maintenance cost.
Invention content
The utility model is intended to provide a kind of film delivery tension device simple in structure, to simplify device structure.
Film delivery tension device described in the utility model includes the input roll shaft and outlet roller being arranged along conveying direction
Axis, separately has the tensioning holder of fixed setting and middle part to be articulated with the adjusting rod on tensioning holder, and one end of adjusting rod is set to defeated
Enter between roll shaft and output roll shaft and two or more adjusting roll shafts is housed thereon, the other end of adjusting rod is lifted with counterweight
Block, and clump weight is more than the torque of hinge joint in the middle part of adjusting rod the torque that all adjusting roll shafts exchange hinge joint in the middle part of pole；
Film alternately transfers to output roll shaft again after inputting roller bearing around all adjusting roll shafts.
Film delivery tension device described in the utility model, film or film roll are from input roll shaft input, by tensioning
It is exported from output roll shaft to follow-up work after device.In the process, film alternately bypasses all adjustings of adjusting rod one end
Roll shaft；On the other hand, clump weight because the torque that adjusting rod is applied it is larger so that all adjusting roll shafts have in the middle part of the adjusting rod
The trend of hinge joint rotation, this kind of trend produce tension to the film staggeredly bypassed；Meanwhile persistently being conveyed in film
In the process, adjusting rod can in response to the vibrations of film or conveying dynamics, speed adjusting and carry out the rotation of adaptivity, to protect
Card film is conveyed in tensioning state always, greatly improves the conveying quality of film.The film delivery tension device
Structure it is extremely simple, but can effectively ensure that the conveying quality of film, to effectively simplify device structure, also reduce
The requirement of precision and work difficulty is made, while reducing production and maintenance cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of film delivery tension device.
Specific implementation mode
A kind of film delivery tension device includes the input roll shaft 1 being arranged along conveying direction and output roll shaft 2, is separately had solid
Surely the tensioning holder 3 being arranged and middle part are articulated with the adjusting rod 4 on tensioning holder, one end of adjusting rod be set to input roll shaft and
Two or more adjusting roll shafts 5 is housed between output roll shaft and thereon, the other end of adjusting rod is lifted with clump weight 6, and matches
Pouring weight is more than the torque of hinge joint 9 in the middle part of adjusting rod the torque that all adjusting roll shafts exchange hinge joint in the middle part of pole；Film 10
Output roll shaft is alternately transferred to again around all adjusting roll shafts after inputting roller bearing.
As shown in Figure 1, film or film roll are exported from output roll shaft after from input roll shaft input after tensioning apparatus
Continuous work.In the process, film alternately bypasses all adjusting roll shafts of adjusting rod one end；On the other hand, clump weight is because right
The torque that adjusting rod applies is larger so that there is all roll shafts that adjust the trend around hinge joint rotation in the middle part of adjusting rod, this kind to become
Gesture produces tension to the film staggeredly bypassed；Meanwhile during film persistently conveys, adjusting rod can be in response to film
Vibrations or conveying dynamics, speed adjusting and carry out the rotation of adaptivity, to ensure that film is in tensioning state always
It is conveyed, greatly improves the conveying quality of film.
The film delivery tension device, adjusting rod 4 one end dress there are two adjust roll shaft 5, including with input roll shaft 1
Roll shaft is adjusted apart from closer first and adjusts roll shaft from second farther out with input roller wheelbase, the film laid out from input roll shaft
The first top for adjusting roll shaft is first bypassed, further around the lower section for crossing the second adjusting roll shaft；In addition, being equipped with transition roller on tensioning holder 3
Axis 7, film transfer to output roll shaft 2 after the second adjusting roll shaft around transition roll shaft.The tensioning apparatus of the structure is relatively simple,
Utmostly it can simplify device structure in Shangdi under the premise of ensureing tension effects；Meanwhile being provided with for transition roll shaft is conducive to
The stability for improving film conveying, make up adjust roll shaft moved in adjustment process and the influence that generates, to enable film
More steadily conveyed.
The film delivery tension device, is tensioned on holder 3 and gag lever post 8 is housed, and gag lever post is set on adjusting rod and cuts with scissors
The lower section of shaft between contact 9 and clump weight 6.If this is because the preponderance of clump weight, or inputted from input roll shaft
Film excessively relaxes, and breeding block is likely to that film is made exceedingly to be moved to improper position, so as to cause in equipment transmission process
Failure is generated, the stable operation of equipment is unfavorable for.
