Description

Technical Field

[0001] The utility model relates to the technical field related to aluminum coils, and in particular to an aluminum coil assembly with a return locking function. Background Art

[0002] Aluminum strip is a metal product that has been processed by rolling and bending. It is widely used in the fields of electronics, construction, packaging and transportation because of its advantages of light weight, corrosion resistance and strong plasticity. In order to facilitate transportation, most of the existing aluminum strips are wound on a rigid sleeve to form a roll structure, and then the aluminum coil can be directly loaded on the production line for feeding. However, when there is traction pulling the aluminum coil, the aluminum coil is very likely to over-rotate and then rotate back, which will cause the aluminum coil to become loose. In addition, since the aluminum sheet has a certain bending state due to being wound on the rigid sleeve for a long time, this will have a certain impact on the subsequent processing of the aluminum sheet.

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0044] like Figure 1-12 As shown, an aluminum coil assembly with a return locking function includes a hollow shaft roller 3, both ends of the hollow shaft roller 3 are sleeved with a main bearing seat 7, and the outer surface of the main bearing seat 7 is sleeved with a baffle 1 that can rotate relative to the hollow shaft roller 3;

[0045] The top ends of the two baffles 1 are provided with strip-shaped slide grooves 2;

[0046] Also includes a return stop mechanism 6;

[0047] The check mechanism 6 includes two sliding blocks 61 and two one-way rollers 65 that cooperate with each other. The two sliding blocks 61 can slide up and down with the two strip-shaped slide grooves 2 respectively. The two ends of each one-way roller 65 are rotatably connected to the two sliding blocks 61. The sliding blocks 61 are also equipped with one-way bearings 63 that are sleeved on the ends of the one-way rollers 65.

[0048] In this embodiment, the strip-shaped slide groove 2 can penetrate the top end of the baffle 1, so that the return stop mechanism 6 can be easily installed and removed.

[0049] When the aluminum coil is unwound, the aluminum coil is wound on the hollow shaft roller 3, which is connected to the unwinding rotating drive structure, and the baffle 1 is connected to the unwinding fixed structure. The return mechanism 6 is assembled on the two-way slide trough 2 and abuts against the outermost layer of the aluminum coil under the action of its own weight. The end of the aluminum coil passes through the two one-way rollers 65 and is connected to the unwinding traction structure. Under the action of the main bearing seat 7, when the rotating drive structure is started, the hollow shaft roller 3 can be driven to rotate relative to the baffle 1, and under the action of the unwinding traction structure, the aluminum strip will be driven to be transported forward. Due to the setting of the one-way bearing 63, the one-way roller 65 can only rotate in one direction, that is, it can only rotate in the direction of conveying the aluminum strip forward. Fig.10 As shown, in this way, the reflux of the aluminum strip can be restricted to avoid the problem of loosening of the aluminum coil. In the unwinding process, the return stop mechanism 6 can move downward relative to the strip chute 2 under the action of its own weight, that is, it can adaptively always abut against the outermost layer of the aluminum coil. Since the one-way roller 65 itself has a certain height, when the aluminum strip passes between the two one-way rollers 65, the downward curvature of the aluminum strip can be reversely shaped upward, as shown in FIG. Fig.11 As shown, this can facilitate the quality and efficiency of subsequent aluminum sheet processing.

[0050] Preferably, the outer surface of the one-way roller 65 is connected to a plurality of axially arranged flexible strips 69 along its circumferential direction.

[0051] In this embodiment, the flexible strip 69 can assist the one-way roller 65 in shaping the aluminum strip upwards, and can also reduce the wear of the one-way roller 65 on the surface of the aluminum strip. The flexible strip 69 can be made of silicone, rubber and other materials.

[0052] Preferably, a limiting protrusion 66 is provided on the side end of the sliding block 61;

[0053] A limiting groove 21 capable of cooperating with the limiting protrusion 66 is formed on the inner side surface of the strip-shaped slide groove 2 .

[0054] In this embodiment, the limit position of the upward and downward movement of the check mechanism 6 can be limited by the cooperation between the limit protrusion 66 and the limit groove 21. In this way, the check mechanism 6 can be prevented from being separated from the baffle 1, reducing the risk of component loss.

[0055] It is worth noting that when the aluminum strip is wound using the present embodiment, the hollow shaft roller 3 should be connected to the winding rotation drive structure, the baffle 1 should be connected to the unwinding fixed structure, the head end of the aluminum strip should pass under the check mechanism 6 and be connected to the hollow shaft roller 3, and the hollow shaft roller 3 can be driven to rotate relative to the baffle 1 by starting the winding rotation drive structure, so that the aluminum strip can be wound on the hollow shaft roller 3. Among them, the check mechanism 6 will always remain in contact with the outermost aluminum strip under the action of its own weight, which can play a certain compression role on the winding of the aluminum strip, thereby improving the compactness of the aluminum coil.

[0056] In order to achieve the connection between the head end of the aluminum strip and the hollow shaft roller 3, preferably, a receiving cavity 11 is provided at the ring side end of the hollow shaft roller 3, and a through slit 10 that can communicate with the receiving cavity 11 is provided on the outer surface of the hollow shaft roller 3;

[0057] A locking mechanism 9 is installed in the accommodating cavity 11;

[0058] The locking mechanism 9 includes a locking roller 91, both ends of which are linked to rotating columns 93. The two rotating columns 93 are rotatably connected to the hollow shaft roller 3. Any one of the two rotating columns 93 passes through the axial side end of the hollow shaft roller 3, and a locking handle 94 is connected to the end of the rotating column 93. A plurality of locking teeth 92 are also arranged on a partial annular surface of the locking roller 91.

[0059] When in use, first rotate the locking handle 94 to adjust the circumferential position of the locking roller 91 so that the locking teeth 92 are located opposite to the through-slit 10, then pass the head end of the aluminum strip through the through-slit 10 and locate at the bottom end of the accommodating cavity 11, and then rotate the locking handle 94 in the opposite direction to adjust the circumferential position of the locking roller 91 so that the locking teeth 92 are located opposite to the bottom of the accommodating cavity 11. In this way, the locking teeth 92 can lock the head end of the aluminum strip in the accommodating cavity 11.

[0060] In this embodiment, the through seam 10 may be located at the bottom end region of the accommodating cavity 11. Figure 7 It may also be located in the middle area of ​​the accommodating chamber 11, such as Fig. 9 shown.

[0061] In order to prevent the locking handle 94 from accidentally rotating and affecting the fixation of the head end of the aluminum strip, preferably, a locking hole 97 is provided on the locking handle 94;

[0062] The hollow shaft roller 3 is provided with a second locking hole 31 corresponding to the first locking hole;

[0063] When the locking roller 91 is rotated so that the plurality of locking teeth 92 are located facing the bottom of the accommodating cavity 11, the first locking hole is connected to the second locking hole;

[0064] It also includes a latch post 95, the inner end of which passes through the first locking hole and is located in the second locking hole.

[0065] To facilitate the operation of the latch column 95 , preferably, a latch handle 96 is extended from the outer end of the latch column 95 .

[0066] As another preferred embodiment, a screw or a bolt may be used to replace the latch column 95 , and the state of the locking handle 94 may be locked by passing the screw through the locking hole 1 97 and threading it into the locking hole 2 31 .

[0067] Preferably, each of the sliding blocks 61 includes an upper sliding section 67 and a lower sliding section 68 located below the upper sliding section 67 and detachably connected to the upper sliding section 67;

[0068] The two one-way rollers 65 are connected to the upper sliding section 67 and the lower sliding section 68 respectively.

[0069] In this embodiment, the upper sliding section 67 and the lower sliding section 68 can be connected by screws and bolts, or can be clamped by a connecting block.

[0070] like Figure 4 As shown, the side end of the upper sliding section 67 may be provided with an upper sliding protrusion, and the side end of the lower sliding section 68 may be provided with a lower sliding protrusion. When the upper sliding section 67 is connected to the lower sliding section 68, the upper sliding protrusion and the lower sliding protrusion together form the limiting protrusion 66.

[0071] Preferably, an upper bracket 62 is provided on the upper sliding section 67, and a lower bracket 64 is provided on the lower sliding section 68;

[0072] The inner ends of the upper bracket 62 and the lower bracket 64 are both connected to the one-way bearing 63 .

[0073] In this embodiment, the inner ring of the one-way bearing 63 is sleeved on the outer surface of the one-way roller 65, and the outer ring of the one-way bearing 63 is connected to the upper bracket 62 or the lower bracket 64. The upper bracket 62 and the lower bracket 64 can both be arc-shaped, so that they are more suitable for the outer ring structure of the one-way bearing 63.

[0074] Preferably, a brake gear is sleeved on the outer surface of one end of the hollow shaft roller 3, and the brake gear includes a plurality of brake teeth 8;

[0075] A slide rail 4 is installed on the outer surface of the baffle 1 , and a brake rod 5 is slidably installed on the slide rail 4 . A brake block 51 that can cooperate with the brake tooth 8 is arranged at the inner end of the brake rod 5 .

[0076] In this embodiment, the relative rotation between the hollow shaft roller 3 and the baffle 1 can be limited by the cooperation between the brake block 51 and the brake tooth 8, so as to avoid accidental winding or unwinding operation. When used, the brake block 51 and the brake tooth 8 can be controlled to engage or disengage by sliding the brake rod 5.
