Description

Technical Field

[0001] The invention relates to the technical field of composite film processing, and in particular to a high-barrier aluminum-plated PE composite film, a production process and production equipment. Background Art

[0002] High barrier aluminized PE composite film is a high-performance packaging material, which is composed of multiple layers of materials. In order to improve the density, uniformity and mechanical strength of each layer of the composite film, a calendering device is usually used to calender the multilayer film together to form a composite film during processing. When the calendering device is processing, it is necessary to adjust the spacing between the upper and lower rollers or the upper and lower pressure plates according to the thickness of the film. The existing calendering device is adjusted by hand-tightening nuts, and in order to maintain stability, the number of nuts used for adjustment is large, and the adjustment accuracy is relatively limited. During adjustment, multiple measurements and debugging are required to achieve the required accuracy, which is extremely cumbersome.

[0003] To this end, Chinese patent CN221456545U discloses a calendering device for processing composite film for pharmaceutical packaging, which enables a user to control the extension or shortening of a first electric push rod through a control panel. At the same time, when the first electric push rod is extended, the slide plate is moved to the right by the first electric push rod, and the distance between the upper pressing plate and the lower pressing plate is increased through the cooperation of the first strip hole, the first cylinder, the second strip hole, the second cylinder and the third strip hole. When the first electric push rod is shortened, the slide plate is moved to the left by the first electric push rod, and the distance between the upper pressing plate and the lower pressing plate is reduced through the cooperation of the first strip hole, the first cylinder, the second strip hole, the second cylinder and the third strip hole. Then, the user can control the distance between the upper pressing plate and the lower pressing plate by operating the control panel, thereby making the calendering device more convenient to use.

The composite film 5 is composed of two high-barrier aluminized PE films bonded by composite glue, and a material roller for controlling the movement of the film material is provided on the frame 1. After the two high-barrier aluminized PE films are bonded, the calendering process is performed by the pressing roller 131.

The frame 1 is provided with a controller for human-machine interaction, and the linear drive 23 is preferably a linear cylinder, and the linear drive 23 is electrically connected to the controller; the linear drive 23 is provided with a push rod 231 for pushing the mounting seat 12, and the operator first sends a signal to the linear drive 23 through the controller, and the linear drive 23 pushes the mounting seat 12 through the push rod 231, and the mounting seat 12 pushes the movable seat 121 to move through the first elastic member 122, and the movable seat 121 drives the first rotating shaft 13 and the pressure roller 131 to move, thereby quickly adjusting the spacing between the two pressure rollers 131, and after the spacing is adjusted to near the specified value, the movable seat 121 is controlled to move through the second adjustment mechanism 3, thereby achieving the effect of accurately controlling the spacing between the two pressure rollers 131, and after the adjustment is completed, the PE composite film 5 is processed by the two pressure rollers 131.

[0038] Reference Figure 1 and Fig. 9 The second adjusting mechanism 3 includes a second rotating shaft 31, a guide plate 32 and a rotation driving assembly 33; the second rotating shaft 31 is rotatably arranged on the frame 1 through a bearing, the guide plate 32 is sleeved on the second rotating shaft 31, and two second slide rails 321 are provided on the guide plate 32, and the two slide rails are annularly symmetrically arranged about the axis of the guide plate 32, and the two first rotating shafts 13 are respectively slidably matched with the two second slide rails 321; the rotation driving assembly 33 is arranged on the frame 1, and the rotation driving assembly 33 is used to drive the guide plate 32 to rotate.

The operator first sends a signal to the linear drive 23 through the controller, and the linear drive 23 pushes the mounting seat 12 through the push rod 231. The mounting seat 12 pushes the movable seat 121 to move through the first elastic member 122, and the movable seat 121 drives the first rotating shaft 13 and the pressure roller 131 to move, thereby quickly adjusting the spacing between the two pressure rollers 131. After the spacing is adjusted to a value near the specified value, the guide plate 32 is driven to rotate through the rotary drive assembly 33, and the guide plate 32 pushes the second rotating shaft 31 through the side wall of the second slide rail 321, and the second rotating shaft 31 is slidably matched with the first slide rail 11, and the movable seat 121 is driven to move through the second rotating shaft 31, thereby achieving the effect of accurately controlling the spacing between the two pressure rollers 131. After the adjustment is completed, the PE composite film 5 is processed by the two pressure rollers 131.

[0040] Reference Figure 7 and Figure 8 The locking assembly 24 includes a locking block 241 and a third elastic member 242. The locking block 241 is slidably mounted on the mounting seat 12.

When adjusting the position of the mounting seat 12, the operator first adjusts the limiting position of the mounting seat 12 by the locking assembly 24 through the control device 4, and then sends a signal to the linear driver 23 through the controller. The linear driver 23 pushes the mounting seat 12 through the push rod 231, and the mounting seat 12 pushes the movable seat 121 to move through the first elastic member 122. The movable seat 121 drives the first rotating shaft 13 and the pressure roller 131 to move, thereby quickly adjusting the distance between the two pressure rollers 131. When the mounting seat 12 moves to the specified position, the locking block 241 is locked under the elastic force of the third elastic member 242. Under the action, it is plugged into and matched with the slot 211 in the position, and then the movement of the mounting seat 12 is restricted by the cooperation between the locking block 241 and the slot 211, and then the guide plate 32 is driven to rotate by the rotation drive component 33, and the guide plate 32 pushes the second rotating shaft 31 through the side wall of the second slide rail 321, and the second rotating shaft 31 is slidably matched with the first slide rail 11, and the movable seat 121 is driven to move by the second rotating shaft 31, thereby achieving the effect of accurately controlling the distance between the two pressure rollers 131.

[0043] The present invention realizes the function of adjusting the locking position of the mounting seat 12 through the mounting rod 41 and the control component 42. When adjusting the position of the mounting seat 12, the operator first controls the push block 411 at the specified position to move in the direction away from the mounting seat 12 through the control component 42, so that the push block 411 no longer blocks the slot 211, while the push blocks 411 at other positions still block the slot 211, adjusts the limiting position of the mounting seat 12 by the locking component 24, and then sends a signal to the linear drive 23 through the controller, and the linear drive 23 pushes the mounting seat 12 through the push rod 231, and the mounting seat 12 pushes the movable seat 121 to move through the first elastic member 122, and the movable seat 121 drives the first rotating shaft 13 and the pressure roller 131 to move, thereby quickly adjusting the distance between the two pressure rollers 131.

Before processing, the operator sends a signal to the rotary driver 432 through the controller to drive the screw 431 to rotate, and the screw 431 drives the two movable blocks 422 threadedly connected thereto to move synchronously in the opposite direction, and the movable block 422 drives the extrusion rod 4221 to move, and the extrusion rod 4221 pushes the oblique protrusion 4111 when it contacts the inclined surface of the oblique protrusion 4111, overcoming the elastic force of the fourth elastic member 421 to drive the push block 411 to move in a direction away from the slot 211, so that the push block 411 no longer fills the slot 211, and when the mounting seat 12 moves to the slot 211, since the push block 411 no longer fills the slot 211, the locking block 241 is stuck in the slot 211 under the elastic force of the third elastic member 242, thereby completing the locking effect on the mounting seat 12.

[0046] Reference Fig. 9 and Fig.12 : The rotating drive assembly 33 includes a third rotating shaft 331, a rotating gear 332, a gear ring 333 and a rotating handle 334.

The damping block 341 abuts against the surface of the guide plate 32 under the elastic force of the fifth elastic member 342.

[0049] The present invention realizes the function of hindering the rotation of the guide plate 32 through the fifth elastic member 342 and the damping block 341. When the position of the mounting seat 12 is adjusted by the first adjustment mechanism 2, since the first rotating shaft 13 is slidably matched with the second slide rail 321 on the guide plate 32, when the mounting seat 12 drives the movable seat 121 to move, the guide plate 32 will be pushed to rotate. Although the guide plate 32 drives the rotating gear 332 to rotate through the gear ring 333, the required torque is large in order to accelerate the transmission structure. However, in order to ensure that the second adjustment mechanism 3 has a sufficient and stable adjustment stroke, when the movable seat 121 is pushed to move by the mounting seat 12, it is necessary to ensure that the first elastic member 122 is in a compressed state. For this purpose, a damping assembly 34 is provided to further hinder the rotation of the guide plate 32, so that a larger torque is required when driving the guide plate 32 to rotate, and then when the movable seat 121 is pushed to move by the mounting seat 12, the first elastic member 122 is stably compressed. When the position of the movable seat 121 is adjusted by the second adjustment mechanism 3, the first elastic member 122 releases its elastic properties, so that the two pressure rollers 131 are moved closer together for fine adjustment. The abutment between the damping block 341 and the guide plate 32 can also prevent the pressure rollers 131 from rotating by themselves during processing and changing the spacing between the pressure rollers 131.

[0050] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
