Abstract
The utility model discloses a kind of unwinding rack tenslator, this device comprises base, one piece of adapter plate a is respectively equipped with in the both sides at described base two ends, in the middle of described base, both sides are also respectively equipped with one piece of adapter plate b, a movable arm is movably equipped with respectively on the top, both sides of every block adapter plate b, a carrying roller is provided with between movable arm on this movable arm and another plate adapter plate b, the medial surface of described every block adapter plate a is movably equipped with a cylinder, a mouth corresponding movable arm respectively of this cylinder, and be connected with the connection mode of activity.This apparatus structure is simple and clear, can according to material webs around number control the tension force of material.
Description
Technical field
The utility model relates to a kind of unwinding rack tenslator, belongs to mechanical field.
Background technology
Each wrapping machine all needs unwinding rack, and this unwinding rack is mainly used for putting the defeated of material.Unwinding rack used on each wrapping machine is at present when defeated putting material, because material has certain distance from wrapping machine, after material enters wrapping machine, because the material on unwinding rack is fixed by rotating shaft, when to wrapping machine charging, material between unwinding rack and wrapping machine cannot obtain a tension force, thus material is easy to land, and causes material to be easily stained with dust.Because material is after landing, when the charging of wrapping machine, material can be held in the palm, make material and ground have certain friction, cause damage of material, cannot use.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of unwinding rack tenslator, and this apparatus structure is simple and clear, can according to material webs around number control the tension force of material.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of unwinding rack tenslator, this device comprises base, one piece of adapter plate a is respectively equipped with in the both sides at described base two ends, in the middle of described base, both sides are also respectively equipped with one piece of adapter plate b, a movable arm is movably equipped with respectively on the top, both sides of every block adapter plate b, a carrying roller is provided with between movable arm on this movable arm and another plate adapter plate b, the medial surface of described every block adapter plate a is movably equipped with a cylinder, a mouth corresponding movable arm respectively of this cylinder, and be connected with the connection mode of activity.
Further, the top of described adapter plate a has the semicircle axial trough for mounting material reel.
Further, the outside face of described carrying roller respective material reel.
The beneficial effects of the utility model are: the utility model regulates the angle of movable arm by cylinder, when reels of material is thicker, movable arm is driven to raise by cylinder, make the outside face of the outside face of carrying roller and reels of material tangent, when material is slowly admitted to after in package packing machine, reels of material attenuates, now, movable arm is driven to lower by cylinder, the outside face of carrying roller is still attached on the outside face of reels of material, ensure that the material between the utility model and wrapping machine has a tension force, thus avoid material and land.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model part-structure schematic diagram;
Fig. 3 is the utility model status architecture schematic diagram.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Figure 1-3, a kind of unwinding rack tenslator, this device comprises base 1, one piece of adapter plate a2 is respectively equipped with in the both sides at base 1 two ends, the middle both sides of base 1 are also respectively equipped with one piece of adapter plate b3, a movable arm 4 is movably equipped with respectively on the top, both sides of every block adapter plate b3, a carrying roller 5 is provided with between movable arm 4 on this movable arm 4 and another plate adapter plate b3, the medial surface of every block adapter plate a2 is movably equipped with a cylinder 6, a mouth corresponding movable arm 4 respectively of this cylinder 6, and be connected with the connection mode of activity.The top of adapter plate a2 has the semicircle axial trough 20 for mounting material reel.The outside face of carrying roller 5 respective material reel 7.
The utility model regulates the angle of movable arm 4 by cylinder 6, when reels of material 70 is thicker, movable arm 4 is driven to raise by cylinder 6, make the outside face of the outside face of carrying roller 5 and reels of material 70 tangent, when material is slowly admitted to after in package packing machine, reels of material attenuates, now, movable arm 4 is driven to lower by cylinder 6, the outside face of carrying roller 5 is made still to be attached on the outside face of reels of material 7, ensure that the material between the utility model and wrapping machine has a tension force, thus avoid material and land.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
