Spring between thrust bearing.
User adjusts described regulation wheel, compresses described spring, and described spring is compressed against nearly described plain thrust bearing, changes
Becoming the frictional force between described plain thrust bearing and described driven pulley, described drivewheel engages with described driven pulley, in friction
In the case of power changes, the angular velocity of rotation of described drivewheel also can change accordingly, equipped with film roll on described solid winding apparatus, described
Drivewheel decides the rotary speed of described carrying roller, the speed of the most described film roll, thus regulates the tension force of described film roll, described
Actively described in wheel belt during driven pulley, owing to driven pulley exists frictional force, described drivewheel angular velocity can control speed frictional force
Size can control the tension force of film roll, described spring is not to directly bear against torr film seat end face, but is pressed in described plane thrust
On bearing, film roll rotates uniformly, there is not the phenomenon that slack list, limit is tight, ensures to walk film length consistent, and packaging product film is consistent.
As of the present utility model preferably, described driven pulley is provided with packing ring away from the one side of described spring.
As of the present utility model preferably, described packing ring is wool felt packing ring.
The sufficiently large contact area ensureing friction of wool felt packing ring, whole friction is plane contact, and frictional force is uniform.
As of the present utility model preferably, described solid winding apparatus comprises the inner conical-tube and external conical-tube being located on described carrying roller.
As of the present utility model preferably, described inner conical-tube one end mutually close with described external conical-tube is for drawing end in.
As of the present utility model preferably, also comprise for controlling relative distance between described inner conical-tube and described external conical-tube
Locking wheel.
As of the present utility model preferably, also comprise the bearing holder (housing, cover) being connected on described carrying roller.
In sum, this utility model has the advantages that
1, described drivewheel angular velocity can control the size of speed frictional force and can control the tension force of film roll.
2, described spring is not to directly bear against torr film seat end face, but is pressed on described plain thrust bearing, and film roll rotates
Uniformly, there is not the phenomenon that slack list, limit is tight, ensure to walk film length consistent, packaging product film is consistent.
3, by the transmission of gear, film roll stopping at an arbitrary position is reliable, uses fine module gear, and film roll is in any position
When putting stopping, the amplitude of swing is by gear backlash control.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
Embodiment 1, as shown in Figure 1, Figure 2 and Figure 3: a kind of for layer tension control device, comprises for roller bearing 1, also comprises
Gu winding apparatus 2, Gu winding apparatus 2 comprises carrying roller 23, carrying roller 23 is rotated by drivewheel 4；Also comprise for regulating 4 turns of drivewheel
