Description

Technical Field

[0001] The utility model relates to the technical field of film roll unwinding, in particular to a reel fixing mechanism and an unwinding device. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber, or other materials. Film is typically stored in a roll format, wound around a reel. Before using film, a reel-out device is required to release the film to the desired length. For smaller-scale film rolls, a simple manual unwinding device is often used.

[0003] For example, the utility model patent with authorization announcement number CN 209889901 U discloses a film unwinding machine, comprising two support frames, each of which is composed of a support frame, a front support frame, and a rear support frame. A fixing frame is fixedly mounted on the outer wall of each adjacent side of the two supports, and a spring with one end fixedly connected to a spring connector is fixedly mounted on the bottom. Both spring connectors are provided with connection holes. A movable rotating shaft with screw holes on both sides is movably mounted between the two spring connectors. Both outer walls of the two front support frames are provided with slide rail grooves, and hexagonal screws are movably inserted into the grooves. During use, the movable rotating shaft of the film unwinding machine can fit the surface of the film roll and move up or down as the circumference of the film roll changes, thereby avoiding the inconvenience caused by the film roll continuing to unwind due to inertia or rewinding due to the resilience of the film itself when the film is pulled out.

[0004] The film roll securing mechanism of the unwinder described above consists of an unwinding shaft with securing rods on either side and a retaining ring with a set screw fixed to the top. Both brackets have securing slots at the top, and the securing rods are movably mounted within the slots. When the unwinder is used to unwind large-tonnage film rolls, the limited operating space in the securing slots makes it difficult to secure the unwinding shaft. Furthermore, the high force required to rotate the film roll during film extraction makes extraction difficult, potentially damaging the film and preventing subsequent inspection. Utility Model Content

[0005] In order to solve the above problems, on the first aspect, the utility model provides a reel fixing mechanism, which increases the operating space when the reel is set up, and at the same time enables the film roll on the reel to be easily rotated for unwinding, thereby improving the convenience of operation.

[0006] The technical solution of the utility model to solve the above problems is as follows:

[0007] A scroll fixing mechanism includes a first bearing portion provided with a first groove, a second bearing portion arranged corresponding to the first bearing portion and provided with a second groove, the second bearing portion is arranged above the first bearing portion, the first groove and the second groove together form a bearing area for supporting the scroll, and also includes a rolling mechanism at least arranged on the first bearing portion for assisting the rotation of the scroll.

[0008] The setting of the bearing area increases the operating space when setting up the reel. Once the reel is placed, the rolling mechanism can slide in contact with the reel and rotate synchronously with the reel, thereby reducing the force required for reel rotation, allowing operators to easily push and unwind large-tonnage film reels, improving operational convenience.

[0009] Preferably, the first groove and the second groove are both arc-shaped.

[0010] The radius of the first groove matches the radius of the reel, and both side walls of the first groove serve as retaining walls for the reel, increasing the operating space when setting up the reel without requiring precision, improving the convenience of reel installation. The radius of the second groove also matches the radius of the reel, used to limit and secure the reel.

[0011] Preferably, the rolling mechanism includes a plurality of fixed radial passive rotation supports evenly distributed in the first bearing portion and with rotation edges protruding from the surface of the first groove; the fixed radial passive rotation supports are bearings or rollers.

[0012] Preferably, the rotation edge of the fixed radial passive rotation support protrudes from the surface of the first groove by 2-5 mm.

[0013] Preferably, the number of the fixed radial passive rotation support members is not less than three, so as to ensure that they can provide sufficient support points for the reel and prevent damage to the fixed radial passive rotation support members due to concentrated force.

[0014] Preferably, one end of the second bearing part is hinged to the first bearing part, and the other end is locked and fixed to the first bearing part via a locking part.

[0015] Preferably, the locking portion includes a locking rod having a bottom end hingedly connected to the first load-bearing portion, and a rotating cover sleeved on a top end of the locking rod to control the locking and unlocking of the first load-bearing portion and the second load-bearing portion. The rotating cover is rotated to move up and down on the locking rod, thereby locking and unlocking the first load-bearing portion and the second load-bearing portion.

[0016] Preferably, the locking portion further comprises a snap-fitting groove vertically disposed at one end of the second supporting portion and extending through the second supporting portion, wherein the locking rod can be snapped into the snap-fitting groove. This arrangement facilitates movement of the locking rod, thereby facilitating locking and unlocking of the first supporting portion and the second supporting portion.

[0017] Preferably, the locking portion includes a buckle, the bottom end of the buckle is hinged to the first bearing portion, and the top end includes a buckling portion, which is buckled to the second bearing portion.

[0018] Preferably, the reel fixing mechanism further comprises a pressure screw arranged above the second bearing portion and passing through the middle of the second bearing portion; the pressure screw can be displaced up and down relative to the second bearing portion.

[0019] The reel is mounted in the load-bearing area. When the film roll needs to be unwound, the pressure screw moves upward and away from the reel. At this time, the film roll can be easily rotated for unwinding. After unwinding, the pressure screw moves down and close to the reel to fix the reel, preventing the film roll from shaking on its own and eliminating safety hazards.

[0020] During use, the reel can be sleeved on the support rod, and then the support rod can be mounted in the bearing area to prevent the reel from being deformed.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the utility model, and are not exhaustive embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.

[0031] A reel securing mechanism 110 includes a first supporting portion 1 and a second supporting portion 2. The first supporting portion 1 is provided with a first groove 11, and the second supporting portion 2 is provided with a second groove 21. The second supporting portion 2 is arranged corresponding to the first supporting portion 1 and is arranged above the first supporting portion 1. The first groove 11 and the second groove 21 together form a supporting area for supporting the reel. The provision of the supporting area provides a large operating space when setting up the reel. The reel securing mechanism 110 also includes a rolling mechanism, which can be provided on the first supporting portion 1 or on both the first supporting portion 1 and the second supporting portion 2.

[0032] Once the reel is placed, the rolling mechanism slides into contact with the reel and rotates synchronously with it. This reduces the force required to rotate the reel, allowing operators to easily unwind large-tonnage film reels, improving operational convenience.

[0033] The first groove 11 is arc-shaped, and its radius matches the radius of the reel. Therefore, both side walls of the first groove 11 can serve as retaining walls for the reel, allowing for ample operating space when setting up the reel without requiring precision, thus improving the convenience of reel installation. The second groove 21 is also arc-shaped, and its radius also matches the radius of the reel, to limit and secure the reel.

[0034] The rolling mechanism includes a plurality of fixed radial passive rotation supports 3, and the plurality of fixed radial passive rotation supports 3 are evenly distributed in the first bearing portion 1, and the rotation edge of the fixed radial passive rotation supports 3 protrudes 2 to 5 mm from the surface of the first groove 11. The fixed radial passive rotation supports 3 can be bearings or rollers. In the present embodiment, they are bearings. In order to ensure that the fixed radial passive rotation supports 3 can provide sufficient support points for the reel and prevent damage to the fixed radial passive rotation supports 3 due to concentrated force, the number of the fixed radial passive rotation supports 3 should be no less than 3. Because their number is related to the size of the groove and the fixed radial passive rotation supports 3, there is no upper limit on the number of the fixed radial passive rotation supports 3.

[0035] When the rotating shaft is placed in the bearing area, the fixed radial passive self-rotating support 3 is in sliding contact with the surface of the reel and can rotate synchronously with the reel. This setting reduces the force required for rotating the reel and facilitates operation by the operator.

[0036] One end of the second bearing part 2 is hingedly connected to the first bearing part 1, and the other end is locked and fixed to the first bearing part 1 through a locking part, so that the first bearing part 1 and the second bearing part 2 are closed. The locking part includes a locking rod 41, a rotating cover 42, and a locking groove 43. The bottom end of the locking rod 41 is hinged to one side of the first bearing part 1, and the rotating cover 42 is sleeved on the top end of the locking rod 41. The rotating cover 42 can move up and down along the locking rod 41 by rotating itself. The locking groove 43 is provided at one end of the second bearing part 2 and vertically passes through the second bearing part 2. The locking groove 43 matches the diameter of the locking rod 41. The locking rod 41 can be locked in the locking groove 43. By rotating the rotating cover 42, the first bearing part 1 and the second bearing part 2 can be locked and unlocked.

[0037] In some embodiments, the locking portion can be a buckle, the bottom end of the buckle is hinged to the first load-bearing portion 1, and the top end includes a buckling portion, which is buckled onto the second load-bearing portion 2, thereby locking the first load-bearing portion 1 and the second load-bearing portion 2.

[0038] A pressure screw 5 is also mounted on the second support portion 2. It is located above the second support portion 2 and extends through the middle of the second support portion 2. It can move up and down relative to the second support portion 2. The reel is mounted in the support area. When the film roll needs to be unwound, the pressure screw 5 moves upward and away from the reel, allowing the film roll to be easily rotated for unwinding. After unwinding is completed, the pressure screw 5 moves downward and close to the reel, securing the reel and preventing the film roll from shaking, eliminating safety hazards.

[0039] In actual use, in order to prevent the reel from being deformed, the reel can be sleeved on the support rod 120 and then mounted in the bearing area through the support rod 120.

[0040] A reeling device includes a support frame 100, two aforementioned reel-fixing mechanisms 110, and a support rod 120. The reel-fixing mechanisms 110 are mounted on the top of the support frame 100 and placed on both sides of the support frame 100. The ends of the support rod 120 are respectively mounted within the bearing areas of the reel-fixing mechanisms 110. In this embodiment, the support frame 100 is H-shaped to enhance the stability of the reeling device. In addition, multiple universal wheels are installed on the bottom of the support frame 100 to facilitate the movement of the reeling device, thereby improving the convenience of operation.

[0041] The use of the reel fixing mechanism 110 and the unwinding device disclosed in the embodiment of the present utility model is as follows:

[0042] When using the unwinding device for unwinding, first, the two ends of the support rod 120 with the reel mounted thereon are respectively mounted in the first groove 11 of the first bearing part 1 of the reel fixing mechanism 110, and the second bearing part 2 is closed with the first bearing part 1. At this time, a bearing area for bearing and limiting the two ends of the support rod 120 is formed between the first bearing part 1 and the second bearing part 2. Then, the first bearing part 1 and the second bearing part 2 are locked by the locking part, and the placement of the support rod 120 is completed. Then, the pressure screw 5 is moved downward so that it can be close to the support rod 120 to fix the support rod 120. When the film roll on the reel needs to be unwound, the pressure screw 5 is moved upward so that it is away from the support rod 120. At this time, the film roll can be easily rotated and unwound, and the film can be easily extracted, which improves the ease of operation, reduces labor intensity, and avoids damage to the film.
