Description

Technical Field

[0001] This utility model relates to the field of rewinding equipment technology, and in particular to a rewinding support device. Background Technology

[0002] Rewinding machines are widely used in modern industry, typically used to break down large-diameter rolls into smaller ones. This process, separating large rolls into smaller ones, is mainly used for materials such as mica tape, kraft paper, plastic film, and adhesive tape. The smaller rolls are then wound into finished products, facilitating transportation, storage, and subsequent processing and slitting. Generally, rewinding machines unwind the roll by rotating an unwinding air shaft and rewind it by rotating a rewinding air shaft. However, existing rewinding machines lack support devices for the unwinding air shaft, resulting in a significant decrease in the radial constraint force exerted by the air shaft on the roll. In this situation, if external tension fluctuates or the equipment operates at high speeds, relative displacement can easily occur between the roll and the air shaft, causing radial swaying of both the air shaft and the roll. This swaying not only leads to quality problems such as scratches and wrinkles on the roll surface but can also cause material breakage and machine shutdown due to tension imbalance, severely impacting production efficiency and product yield. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a reel support device and a rewinder.

[0004] In a first aspect, this application provides a reel support device, comprising:

[0005] A support bar having two opposing ends in a first direction, one end of which is used to support a reel, and the other end is connected to a bushing.

[0006] A pivot is located on one side of the support bar in the first direction, and a bushing is fitted onto the pivot so that the support bar can rotate relative to the axis of the pivot.

[0007] A locking element is located on the side of the pivot near the support bar and flush with the center of the pivot, for locking or unlocking the support bar.

[0008] In one possible implementation, the locking element includes a lock seat, a pin, and an adjusting head. The lock seat is located on the side of the rotating shaft near the support bar. The pin passes through the lock seat along a second direction and extends retractably toward the support bar. The support bar has a pin hole that mates with the pin. The adjusting head is installed at the end of the pin away from the support bar and is used to adjust whether the pin is inserted into or protrudes from the pin hole. The second direction intersects with the first direction.

[0009] In one possible implementation, a fixing base is further included, the fixing base having a mounting cavity, the rotating shaft being rotatably disposed within the mounting cavity, and the locking seat being connected to the fixing base.

[0010] In one possible implementation, the lock seat is located below the support bar, and the pin hole is formed at the lower end of the support bar.

[0011] In one possible implementation, the outer peripheral surface of the adjustment head is provided with anti-slip texture.

[0012] In one possible implementation, the lock seat has a first mounting hole, and the fixing seat has a second mounting hole that matches the first mounting hole.

[0013] In one possible implementation, the mounting base has a third mounting hole on one side relative to the second mounting hole.

[0014] In one possible implementation, the end of the support bar away from the pivot is provided with an arc-shaped groove, and the end of the spool near the support bar is equipped with a bearing, which is adapted to fit the arc-shaped groove so that the support bar supports the spool.

[0015] Secondly, this application also provides a rewinding machine, including the rewind support device described in the above embodiments.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] By connecting a bushing to one end of the support bar and then connecting the bushing to a rotating shaft, the support bar can rotate around the axis of the shaft. When the wound material needs to be fitted onto the shaft, the support bar is first rotated away from the shaft to allow the material to be fitted onto it. Then, the support bar is rotated closer to the shaft until it supports the shaft. Finally, a locking device is used to lock the support bar, ensuring that it does not wobble during the unwinding process and providing stable support to the shaft. In other words, the support bar of this shaft support device provides support during the rotation of the shaft, increasing the radial constraint force of the shaft on the material, effectively reducing radial wobble of the shaft and material, preventing relative displacement between the material and the air shaft, and greatly improving the load-bearing capacity of the material; thus avoiding quality problems such as shaft breakage during high-speed rotation.

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0027] like Figure 1 As shown in the figure, a rewinding machine according to an embodiment of the present invention includes a frame 10, a reel 20 connected to the frame 10, and a reel support device 30 for supporting the reel 20. The reel support device 30 supports the reel 20. In other words, in practical applications, the wound material is placed on the rotating shaft 32, and then the reel support device 30 supports the end of the rotating shaft 32 away from the frame 10. At this time, the rotating shaft 32 can rotate relative to the reel support device 30, ensuring normal unwinding or rewinding of the material.

[0028] Reference Figures 2 to 4 Specifically, the reel support device 30 includes a support bar 31, a rotating shaft 32, and a locking member 33. The support bar 31 has two opposite ends in the first direction X. One end of the support bar 31 is used to support the reel 20, and the other end is connected to a bushing 34. The rotating shaft 32 is located on one side of the support bar 31 in the first direction X, and the bushing 34 is sleeved on the rotating shaft 32 so that the support bar 31 can rotate relative to the axis of the rotating shaft 32. The locking member 33 is located on the side of the rotating shaft 32 near the support bar 31 and is flush with the center of the rotating shaft 32. It is used to lock or unlock the support bar 31.

[0029] In this embodiment, the spool 20 supports the rotating shaft 32 by connecting a bushing 34 to one end of the support bar 31 and connecting the bushing 34 to the rotating shaft 32, so that the support bar 31 can rotate around the axis of the rotating shaft 32. When it is necessary to put the wound material into the spool 20, the support bar 31 is first rotated away from the spool 20 so that the support bar 31 is away from the spool 20 so that the material can be put into the rotating shaft 32. Then, the support bar 31 is rotated towards the rotating shaft 32 until the support bar 31 supports the spool 20. Finally, the locking member 33 is used to lock the support bar 31 to ensure that the support bar 31 will not wobble during the rotation and unwinding process of the spool 20, and to ensure that it can provide stable support force to the spool 20. In other words, the support bar 31 of the rotating shaft 32 support device can provide support during the rotation of the roll 20, thereby increasing the radial constraint force of the roll 20 on the roll material. This can effectively reduce the radial sway of the roll 20 and the roll material, prevent relative displacement between the roll material and the roll 20, and greatly improve the load-bearing capacity of the roll material, thus avoiding quality problems such as shaft breakage during high-speed rotation.

[0030] In one possible implementation, the locking member 33 includes a locking seat 331, a pin 332, and an adjusting head 333. The locking seat 331 is located on the side of the rotating shaft 32 near the support bar 31. The pin 332 passes through the locking seat 331 along the second direction Y and extends retractably toward the support bar 31. The support bar 31 has a pin hole that mates with the pin 332. The adjusting head 333 is installed at the end of the pin 332 away from the support bar 31 and is used to adjust whether the pin 332 is inserted into or protrudes from the pin hole. The second direction Y intersects with the first direction X. It should be noted that the first direction X and the second direction Y are merely hypothetical for ease of describing the positional relationship between components. Specifically, the support bar 31 can be used as a reference; that is, the first direction X refers to the length direction of the support bar 31 (refer to...). Figure 2 The X direction in the diagram refers to the direction of the support bar 31, and the Y direction refers to the height direction of the support bar 31 (see reference). Figure 2 Y direction in ).

[0031] In practical applications, when the end of the reel 20 near the support bar 31 is attached to the support bar 31, the adjusting head 333 is rotated to drive the pin 332 into the pin hole, thereby locking the support bar 31 to prevent it from wobbling during the rotation of the reel 20 and ensuring stable support for the reel 20. When it is necessary to remove or install the roll material on the reel 20, the adjusting head 333 is rotated to drive the pin 332 out of the pin hole. At this time, the support bar 31 can rotate relative to the rotating shaft 32, so that the support bar 31 can rotate away from the reel 20, thereby disengaging the support bar 31 from the support of the reel 20, so that the roll material can be quickly removed or installed.

[0032] In one possible implementation, a fixing base 35 is also included, which has a mounting cavity 35a. The rotating shaft 32 is rotatably disposed within the mounting cavity 35a, and a locking seat 331 is connected to the fixing base 35. In practical applications, the rotating shaft 32 is rotatably disposed within the mounting cavity 35a, and then the fixing base 35 is connected to an external mounting surface, so that the support bar 31 is disposed on the outside of the support bar 31, so that the reel 20 can be quickly supported as needed.

[0033] In one possible implementation, the lock seat 331 is located below the support bar 31, and the pin hole is opened at the lower end of the support bar 31.

[0034] In one possible implementation, the outer peripheral surface of the adjustment head 333 is provided with anti-slip texture 333a. In this way, the anti-slip texture 333a increases the friction with the hand, ensuring that slippage does not occur during the rotation of the adjustment head 333.

[0035] In one possible implementation, the lock base 331 has a first mounting hole 331a, and the fixing base 35 has a second mounting hole that matches the first mounting hole 331a. That is, the lock base 331 is brought into contact with the fixing base 35 so that the first mounting hole 331a and the second mounting hole are aligned. Then, an auxiliary component (such as a bolt) is used to pass through the first mounting hole 331a and the second mounting hole in sequence, so that the lock base 331 can be quickly fixed on the fixing base 35. The structure is simple and easy to assemble and disassemble.

[0036] In one possible implementation, the fixing base 35 has a third mounting hole 35b on the side opposite to the second mounting hole. This facilitates the subsequent fixing of the fixing base 35 to the outside of the roll 20, so that the support bar 31 can rotate about the pivot 32 on the fixing base 35 as the axis of rotation.

[0037] In one possible implementation, the end of the support bar 31 away from the rotating shaft 32 has an arc-shaped groove, and a bearing is installed at the end of the reel 20 near the support bar 31. The bearing is adapted to fit the arc-shaped groove so that the support bar 31 supports the reel 20. In practical applications, after the support bar 31 supports the reel 20, it is necessary to ensure that the rotating shaft 32 can rotate relative to the support bar 31. Therefore, in this embodiment, by providing an arc-shaped groove at the end of the support bar 31 away from the rotating shaft 32 and installing a bearing at the end of the reel 20 near the support bar 31, the reel 20 can rotate relative to the support bar 31 by utilizing the interaction between the bearing and the arc-shaped groove.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
