Description

A film unwinding and correcting device

Technical Field

The utility model relates to the technical field of unwinding deviation correction, in particular to an unwinding deviation correction device for a film.

Background Art

Film unwinding and guiding equipment is usually used to unwind the film material from the roll and keep it flat during the production process to ensure the stability and quality of the film during subsequent processing.

After searching, the Chinese patent with announcement number CN216583213U discloses an automatic unwinding deviation correction device, including a base, a stand is arranged on the left and right sides of the top of the base, a translation deviation correction mechanism is arranged on the base, the translation deviation correction mechanism is respectively connected with two stands, a fine adjustment component is arranged on the top of the two stands, a convenient fixed seat is connected to the top of the two fine adjustment components, an air expansion shaft is arranged between the two convenient fixed seats, the left and right ends of the air expansion shaft are fixedly connected with a connecting shaft, and the two connecting shafts are sleeved with a rotating bearing fixedly connected thereto. The above scheme combines the unwinding and deviation correction systems together, and places the sensor at the feeding port of the lower station, which not only ensures the sensitivity and accuracy of the mechanism response, but also improves the space utilization rate and is relatively economical in cost. At the same time, the gear structure is adopted to ensure the motor power of the active unwinding, and the air expansion shaft can be disassembled at any time when needed to replace the coil. However, the above technical scheme still has the following shortcomings when used:

The above scheme realizes automatic deviation correction by adjusting the position of the stand, but the unwinding structure is arranged on the stand, which makes the overall weight of the stand and the structure thereon higher, and will impose excessive load on the electric cylinder. Excessive load may cause the electric cylinder to operate above its rated load, which may damage the electric cylinder or shorten its service life. Overloading of the electric cylinder may also cause equipment shutdown and maintenance, thereby affecting production efficiency.

Therefore, it is necessary to design a film unwinding and correcting device to solve the above problems.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Referring to Fig. 1-2, a film unwinding and deviation correction device includes an unwinding frame 1, an air expansion shaft 2 is arranged on the unwinding frame 1, and two connecting components are arranged on the unwinding frame 1. The air expansion shaft 2 is connected to the unwinding frame 1 through the two connecting components. The connecting components include a mounting rod 31, a slot 32, a slide rod 33, two limit slots 34, two limit blocks 35 and a spring 36. The mounting rod 31 is rotatably mounted on the unwinding frame 1, the slot 32 is opened at one end of the mounting rod 31, and the slide rod 33 is slidably connected in the slot 32. The outer surface of the slide rod 33 fits with the slot wall of the slot 32, and one end of the slide rod 33 extends to the outside of the slot 32. The two slide bars 33 are coaxially arranged with the gas expansion shaft 2, and the two limit grooves 34 are both provided on the groove wall of the slot 32. The two limit blocks 35 are both fixed on the slide bar 33. The two limit blocks 35 are respectively slidably connected in the two limit grooves 34. One end of the spring 36 is connected to the slot 32, and the other end is connected to the slide bar 33. The staff can use the servo cylinder 45 to adjust the position of the coil to realize the function of deviation correction. Since the servo cylinder 45 directly acts on the slide bar 33 and the gas expansion shaft 2, it will not drive the entire unwinding frame 1 to move, so as to avoid excessive load on the servo cylinder 45 during the adjustment process.

The unwinding frame 1 is provided with an adjustment component, which includes an annular sleeve 41, a correction rod 42, a groove 43, a ball 44, a servo cylinder 45 and a bracket 46. The annular sleeve 41 is fixedly sleeved on one of the sliding rods 33, and the bracket 46 is fixed on the unwinding frame 1. The servo cylinder 45 is installed on the bracket 46. The correction rod 42 is fixed on the telescopic end of the servo cylinder 45. The groove 43 is opened at one end of the correction rod 42. The ball 44 is movably arranged in the groove 43, and the ball 44 is in contact with the annular sleeve 41. The shape of the groove 43 is adapted to the shape of the ball 44, and part of the ball 44 extends to the outside of the groove 43. When the air expansion shaft 2 drives the two sliding rods 33 to rotate, the annular sleeve 41 will also rotate accordingly. When the annular sleeve 41 rotates, the ball 44 can roll. The function of the ball 44 is to reduce the friction between the correction rod 42 and the annular sleeve 41. In this case, the correction rod 42 can correct the coil during the rotation of the coil.

The specific working principle of the utility model is as follows:

When the unwinding and correcting device proposed by the utility model is in use, the staff installs the coil on the air expansion shaft 2. When the coil needs to be corrected and adjusted, the staff starts the servo cylinder 45. When the servo cylinder 45 is running, it drives the correcting rod 42 to move. When the correcting rod 42 squeezes the annular sleeve 41, the sliding sleeve 41 can drive the corresponding sliding rod 33 to move, which makes the air expansion shaft 2 and the coil thereon move in one direction. When the correcting rod 42 does not squeeze the annular sleeve 41, the air expansion shaft 2 and the coil thereon will move in another direction under the action of the two springs 36. Therefore, the staff can use the servo cylinder 45 to adjust the position of the coil to realize the correction function. Since the servo cylinder 45 directly acts on the sliding rod 33 and the air expansion shaft 2, it will not drive the entire unwinding frame 1 to move, thereby avoiding excessive load on the servo cylinder 45 during the adjustment process.

A groove 43 is provided at one end of the correcting rod 42, and a rollable ball 44 is provided in the groove 43. The correcting rod 42 pushes the annular sleeve 41 through the ball 44. The setting of the ball 44 enables relative rotation between the correcting rod 42 and the annular sleeve 41. When the air shaft 2 drives the two sliding rods 33 to rotate, the annular sleeve 41 will also rotate accordingly. When the annular sleeve 41 rotates, the ball 44 can roll. The function of the ball 44 is to reduce the friction between the correcting rod 42 and the annular sleeve 41. In this case, the correcting rod 42 can correct the coil during its rotation.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
