Description

Technical Field

[0001] This utility model relates to the field of roll material axis limiting technology, specifically a film roll axial movement limiter. Background Technology

[0002] In the production and processing of film rolls, the film rolls are typically wound on rollers for transportation, storage, and subsequent processing. However, in actual production scenarios, the rollers of the film rolls often face the problem of axial movement. This can not only cause the film rolls to loosen, but also lead to wrinkles, damage, and even affect the smooth operation of the entire production process, causing unnecessary economic losses to the company.

[0003] Traditional limiting devices mostly employ simple mechanical blocking methods, such as setting fixed baffles at both ends of the roller. However, this method has many limitations. On the one hand, fixed baffles cannot adapt to rollers of different sizes. When changing to different specifications of film rolls, frequent adjustments or replacements of the baffles are required, making the operation cumbersome and greatly reducing production efficiency. On the other hand, this fixed blocking method lacks flexibility and may not provide effective limiting when facing rollers with special shapes or sizes, resulting in poor limiting performance.

[0004] Therefore, a film roll axial movement limiter is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a film roll axial movement limiter to solve the problems mentioned in the background art.

[0012] As a preferred embodiment of this utility model, the outer shell surface is provided with a transverse groove, and the actuating rod passes through the inner side of the transverse groove.

[0013] As a preferred embodiment of this utility model, the outer shell surface is provided with a vertical groove, the tray surface is arc-shaped, and one end of the tray passes through the vertical groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The design of this limiter can adapt to rollers of different sizes of wound film rolls. Regardless of the diameter of the roller, when it is placed on the pallet, the pallet will move downward under the action of gravity.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A film roll axial movement limiter includes a mounting plate 2, a bracket 1 fixedly mounted at the lower end of the mounting plate 2, a slide rail 6 fixedly mounted on the surface of the mounting plate 2, an internal threaded slider 5 slidably mounted on the surface of the slide rail 6, and a limiting mechanism 17 fixedly mounted on one side of the internal threaded slider 5.

[0028] As an example of this utility model, the limiting mechanism 17 includes: a housing 7, a limiting groove 16 inside the housing 7, a support plate 9 slidably disposed inside the limiting groove 16, and rotating arms 14 rotatably disposed on both sides of one end of the support plate 9. When the two ends of the roller inside the film roll are placed on the support plate 9, the gravity of the roller acts on the support plate 9. Under the action of gravity, the support plate 9 moves downward in the vertical direction along the limiting groove 16. The limiting groove 16 provides precise guidance for the movement of the support plate 9, ensuring that the support plate 9 can slide downward smoothly, while limiting its displacement in other directions, thus ensuring the stability and reliability of the entire limiting process.

[0029] As an example of this utility model, the outer shell 7 is provided with side plates 11 on both sides. A toggle groove 13 is provided on one side surface of the side plate 11. A toggle rod 12 is slidably provided inside the toggle groove 13. The toggle rod 12 is fixed to one end of the rotating arm 14. As the support plate 9 moves downward, the rotating arm 14 connected to its side will also move downward. At this time, the hinge rod 15 plays a key linkage role. One end of the hinge rod 15 is rotatably connected to the inside of the outer shell 7, and the other end is hinged to the surface of the rotating arm 14. When the rotating arm 14 moves downward, the hinge rod 15 will drive the rotating arm 14 to rotate inward. This linkage mechanism enables the vertical movement of the support plate 9 to be converted into the rotational movement of the rotating arm 14.

[0030] As an example of this utility model, a hinge rod 15 is rotatably provided inside the outer shell 7. The other end of the hinge rod 15 is hinged to the surface of the rotating arm 14. A toggle rod 12 is fixedly connected to the end of the rotating arm 14. The toggle rod 12 is located inside the toggle groove 13 on the inner side of the side plate 11. When the rotating arm 14 rotates inward, the toggle rod 12 will slide in the toggle groove 13. The special design of the toggle groove 13 makes the sliding of the toggle rod 12 able to drive the side plate 11 to rotate inward. Under the action of the toggle rod 12, the side plates 11 on both sides will deflect towards the center and gradually clamp the roller inside the film roll.

[0031] As an example of this utility model, a motor 3 is fixedly mounted on the side of the mounting plate 2. A lead screw 4 is driven at the output end of the motor 3. An internally threaded slider 5 is threadedly connected to the surface of the lead screw 4. The internally threaded slider 5 is fixed to the outer shell 7. The motor 3 is fixed to the side of the mounting plate 2, and its output end is driven by the lead screw 4. When the motor starts, the lead screw 4 rotates accordingly. Since the internally threaded slider 5 is threadedly connected to the lead screw 4 and can slide on the surface of the slide rail 6, the rotation of the lead screw 4 is converted into the linear movement of the internally threaded slider 5 along the slide rail 6. The internally threaded slider 5 is fixedly connected to the outer shell 7. Therefore, the movement of the internally threaded slider 5 will drive the outer shell 7 and the entire limiting mechanism 17 to move axially. When the limiting mechanism 17 moves to the desired position, the motor stops working, and the limiting mechanism 17 stops at that position, thereby achieving the positioning of the axial position of the film roll.

[0032] As an example of this utility model, the surface of the outer shell 7 is provided with a transverse groove 8, and the toggle lever 12 passes through the inner side of the transverse groove 8.

[0033] As an example of this utility model, the surface of the outer shell 7 is provided with a vertical groove 10, the surface of the tray 9 is arc-shaped, and one end of the tray 9 passes through the vertical groove 10.

[0034] Working principle: When in use, when the two ends of the roller inside the film roll are placed on the support plate 9, the gravity of the roller acts on the support plate 9. Under the action of gravity, the support plate 9 moves downward in the vertical direction along the limiting slide groove 16. The limiting slide groove 16 provides precise guidance for the movement of the support plate 9, ensuring that the support plate 9 can slide downward smoothly, while limiting its displacement in other directions, ensuring the stability and reliability of the entire limiting process.

[0035] As the tray 9 moves downward, the rotating arm 14 connected to its side also moves downward. At this time, the hinge rod 15 plays a key linkage role. One end of the hinge rod 15 is rotatably connected to the inside of the outer shell 7, and the other end is hinged to the surface of the rotating arm 14. When the rotating arm 14 moves downward, the hinge rod 15 will drive the rotating arm 14 to rotate inward. This linkage mechanism allows the vertical movement of the tray 9 to be converted into the rotational movement of the rotating arm 14.

[0036] A lever 12 is fixedly connected to the end of the rotating arm 14. The lever 12 is located inside the lever groove 13 on the inner side of the side plate 11. When the rotating arm 14 rotates inward, the lever 12 slides in the lever groove 13. The special design of the lever groove 13 allows the sliding of the lever 12 to drive the side plate 11 to rotate inward. Under the action of the lever 12, the side plates 11 on both sides will deflect towards the center and gradually clamp the roller inside the film roll.

[0037] Motor 3 is fixed to the side of mounting plate 2, and its output end is connected to lead screw 4. When the motor starts, lead screw 4 rotates accordingly. Since the internal threaded slider 5 is threadedly connected to lead screw 4 and can slide on the surface of slide rail 6, the rotation of lead screw 4 is converted into linear movement of internal threaded slider 5 along slide rail 6. This transmission method can precisely control the moving speed and position of internal threaded slider 5, providing power and guidance for the axial movement of the limiting mechanism.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
