Abstract
The utility model discloses a tensioning mechanism, including a transmission shaft. The central section of the transmission shaft is fixedly provided with a charging tray; the right end portion of the transmission shaft is screwingly connected to a product adjusting turn button; the transmission shaft is provided with a spring clip plate at the left side of the charging tray in a clearance-fit manner; the spring clip plate is contacted to the step on the transmission shaft; the transmission shaft is sleeved with a spring movable plate at the left side of the spring clip plate; a spring is provided between the spring movable plate and the spring clip plate; and the left end portion of the transmission shaft is screwingly connected to a spring adjusting turn button. The tensioning mechanism provided in the utility model can provide a force to guarantee coil stock to stay in a stretching state, and the force is guaranteed to be continuous all the time.
Description
Technical field:
Used laminator when the utility model relates to electronic product pad pastings such as mobile phone, MP3 relates to the stretching device that uses on a kind of laminator in particular.
Background technology:
Laminator is in work, and the film that it pasted is wound on the axle, and be used for adjusting shaft and be fixed on coiled strip when rotation pulling on the axle, needed power, popular saying is exactly to make this root axle rotate handy great power.If this power is too big, during the pulling coiled strip, coiled strip has been broken, and does not also make the axle rotation, if this power is too little, behind the pulling coiled strip, axle can continue rotation because of inertia, can not guarantee that coiled strip is in stretching state always, the out of reach job requirement.So need to design the size that a kind of mechanism adjusted and kept this power, stretching device promptly of the present utility model.
The utility model content:
The purpose of this utility model provides a kind of stretching device that is used for laminator.
Technology solution of the present utility model is as follows:
A kind of stretching device comprises transmission shaft, and the middle part of this transmission shaft is fixed with a charging tray, the right part of the described transmission shaft product adjusting knob that is spirally connected; Free-running fit is equipped with a spring clamping plate that is positioned at charging tray left side on transmission shaft, step on this spring clamping plate and the transmission shaft contacts, also be with a spring shifting board that is positioned at the spring clamping plate left side on the transmission shaft, between described spring shifting board and described spring clamping plate, a spring arranged; A spring adjusting knob is spirally connected in the left part of transmission shaft.
Described a kind of stretching device has through hole on the described spring shifting board, and bolt passes described through hole and is screwed onto on the described spring clamping plate.
Described a kind of stretching device, described product adjusting knob has internal thread hole, and there is outside thread described transmission shaft right part, and this external thread bolt connection is in described internal thread hole.
Described a kind of stretching device, described spring adjusting knob has internal thread hole, and described transmission shaft left end has outside thread, and this external thread bolt connection is in described internal thread hole.
The utility model beneficial effect is:
Stretching device of the present utility model, its principle of work is such, zone on the right side of product adjusting knob on the transmission shaft is the zone that coiled strip is installed, this product adjusting knob is used to the coiled strip that is locked, just can not relatively rotate between coiled strip and the axle like this, whole axle is mounted on the fixing vertical plate, the spring shifting board and the spring clamping plate that are used for the tensioning transmission shaft also are mounted in adapter plate, only can move around, can not rotate with axle, bolt is used for these two plates are connected.The spring of the left part of transmission shaft is regulated knob and is screwed onto on the axle, can rotate with axle.When the spring adjusting knob moves forward by the screw thread rotation on the axle, with the spring shifting board of extrusion spring, compression spring, increase and to revolve spring clamping plate and act on pressure on the transmission shaft step, friction force increases thereupon between spring clamping plate and the step (transmission shaft), and on the contrary, friction force reduces thereupon.So just can provide an assurance coiled strip to be in the power of stretching state always, and can guarantee that this power continues always.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1; A kind of stretching device comprises transmission shaft 1, and the middle part of this transmission shaft is fixed with a charging tray 2, the right part of the described transmission shaft 1 product adjusting knob 3 that is spirally connected; Free-running fit is equipped with a spring clamping plate 4 that is positioned at charging tray left side on transmission shaft, step 101 on this spring clamping plate and the transmission shaft contacts, also be with a spring shifting board 5 that is positioned at the spring clamping plate left side on the transmission shaft 1, a spring 6 is arranged between described spring shifting board and described spring clamping plate; A spring adjusting knob 7 is spirally connected in the left part of transmission shaft.
On the described spring shifting board through hole 501 is arranged, bolt 8 passes described through hole and is screwed onto on the described spring clamping plate.
Described product adjusting knob has internal thread hole, and there is outside thread described transmission shaft right part, and this external thread bolt connection is in described internal thread hole.
Described spring adjusting knob has internal thread hole, and described transmission shaft left end has outside thread, and this external thread bolt connection is in described internal thread hole.
