In another embodiment of the present invention, as shown in fig. 1 to 4, the second driving module 21 includes a second threaded rod 211 and a second driving source; the second threaded rod 211 is in threaded connection with the second lower connecting plate 22, the second threaded rod 211 is in rotatable connection with the supporting seat 60, and the second driving source is in linkage connection with the second threaded rod 211 to enable the second threaded rod 211 to rotate, so that the second lower connecting plate 22 is driven to move.

Specifically, the second lower connecting plate 22 is provided with a second internal thread, and the second internal thread penetrates through the left and right surfaces of the second lower connecting plate 22. The shaft of the second threaded rod 211 comprises a second threaded part provided with external threads and a second rotating part with a smooth surface, the second threaded part is in threaded connection with second internal threads on the second lower connecting plate 22, and the second rotating part is in rotatable connection with the supporting seat 60. During the use, second driving source drive second threaded rod 211 rotates to drive second screw portion and rotate, and then make second lower connecting plate 22 remove. The mechanism is simple, the production cost is reduced, and in addition, the assembly difficulty can be reduced.

Further, one end of the second rotating portion of the second threaded rod 211 is provided with a handle through threaded connection. In this embodiment, the second driving source is a manual force, and when the device is used, the second connecting plate can be moved only by rotating the second handle. In the actual production process, there is little opportunity to adjust the position of the second guide roller 40 in the left-right direction, so that manpower is selected as the second driving source, which is beneficial to reducing the production cost.

In another embodiment of the present invention, as shown in fig. 1 to 4, the second moving assembly 20 further includes a second upper sliding rail module 24; the second upper sliding rail module 24 has a movable end moving along the left-right direction, the fixed end of the second upper sliding rail module 24 is fixedly connected with the supporting seat 60, and the movable end of the second upper sliding rail module 24 is fixedly connected with the upper end of the second guide roller 40 through a second upper connecting plate.

Specifically, in the present embodiment, the second upper rail module 24 employs a linear rail. The linear guide rail comprises a second upper slide rail and a second upper slide block, the second upper slide rail extends along the left-right direction, and the second upper slide block is connected with the second upper slide rail in a sliding mode.

During the use, second drive module 21 drive second lower connecting plate 22 to drive the lower extreme of second guide roll 40 and remove along the left-right direction, and then drive the upper end of second guide roll 40, second lower slider and remove along the left-right direction. Adopt linear guide, can reduce the frictional force that the second upper junction plate received when sliding to make the slip of this second upper junction plate more convenient, in addition, linear guide's lubricated simple structure, conveniently add lubricating oil.

In another embodiment of the present invention, the upper end of the second guide roller 40 is provided with a second upper threaded hole; the axis of the second upper threaded hole is parallel to the front-back direction; a second upper waist-shaped hole is formed in the second upper connecting plate; and a second upper bolt penetrates through the second upper waist-shaped hole and is connected with the second upper threaded hole, so that the detachable connection between the second guide roller 40 and the second upper connecting plate is realized.

Specifically, the second upper waist-shaped hole extends in the vertical direction. The second upper bolt penetrates through the second upper waist-shaped hole and is connected with the second upper threaded hole, so that the detachable connection of the second guide roller 40 and the second upper connecting plate is realized. By providing the second upper waist-shaped hole, the upper end of the second guide roller 40 is made adjustable, that is, by adjusting the position of the second upper bolt on the second upper waist-shaped hole, the angle between the second guide roller 40 and the horizontal plane is adjusted. Like this, when realizing that the angle between second guide roll 40 and the horizontal plane is adjustable, through constantly angle regulation to find out the angle that is most suitable for current gilt film transmission, improved practicality and flexibility greatly.

In another embodiment of the present invention, as shown in fig. 1 to 4, the second guide roller 40 is a hollow structure; the second guide roller 40 is provided with a plurality of second air holes 41 which are uniformly distributed; a plurality of second air holes 41 penetrate through the second guide roller 40; a second air pipe joint is in threaded connection with the second guide roller 40, and the inlet end of the second air pipe joint is connected with a second air source through an air pipe; the outlet end of the second air pipe joint is communicated with the inside of the second guide roller 40.

In particular, the second gas source is used to provide a gas flow. When the air-jet type guide roller is used, the second air source generates air flow, the air flow enters the second guide roller 40 through the air pipe, and then the air flow is ejected out of the plurality of second air holes 41 on the second guide roller 40. At this time, the foil wound around the second guide roller 40 is blown by the air flow, and a gap is maintained between the foil and the second guide roller 40. Thereby avoiding the gold stamping film and the second guide roller 40 from rubbing, further avoiding the condition that the coating on the gold stamping film drops or is scratched or scratched, and greatly improving the gold stamping quality.

Furthermore, the air source is electrically connected with a controller, and the controller is also electrically connected with an air pressure detector and an alarm. An air pressure detector is provided on the air pipe to detect the air pressure inside the second guide roller 40, and the controller controls the operation of the alarm and the air source according to the air pressure detected by the air pressure detector. Through setting up the atmospheric pressure monitor on the trachea to can be by the work of controller according to the atmospheric pressure information control siren that the atmospheric pressure monitor surveyed, when atmospheric pressure is less than a definite value, remind noticing through the alarm, the air supply increase work efficiency also can be controlled to the controller simultaneously, keeps the air current pressure in the second guide roll 40, makes gilt membrane keep the suspended state when passing through second guide roll 40, avoids the coating of gilt membrane to be scraped colored.

In another embodiment of the present invention, a first limiting member is disposed on a side of the first guide roller 30 away from the rotating roller 50, and a gap through which the bronzing film can just pass is formed between the first guide roller 30 and the first limiting member. A second limiting part is arranged on one side, away from the rotating roller 50, of the second guide roller 40, and a gap through which the bronzing film can just penetrate is formed between the second guide roller 40 and the second limiting part. So, through setting up first locating part and second locating part to the gilt membrane that is blown by the air current in first air pocket 31 and the second air pocket 41 is stabilized, thereby ensures that the gilt membrane can not blown in disorder and can not take place the skew, and then ensures the normal transport of gilt membrane.

The invention further provides a full-automatic positioning gold stamping production line which comprises the gold stamping film return line mechanism. Because the full-automatic positioning gold stamping production line uses the gold stamping film loop mechanism, the gold stamping film used for one time automatically returns to the production line and is used for the second time, and the purposes of saving materials and improving the utilization rate of the gold stamping film are achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
