Description

Technical Field

[0001] This utility model relates to the field of U-shaped buckle loading technology, and in particular to a plastic reel for use with U-shaped aluminum buckles. Background Technology

[0002] U-shaped aluminum clips are widely used for sealing flexible packaging (such as sausages and emulsion explosives). During production, the clips are arranged into a strip and then wound up by a rolling mechanism for transportation and storage. However, current technology requires the installation of a sensor to synchronously adjust the winding speed, resulting in a complex structure and high cost.

[0003] Existing patent CN204568936U describes a winding mechanism for producing U-shaped aluminum clips. It includes a motor, bearing housing, a rubber disc, and a chuck shaft. The motor is connected to the chuck shaft via the bearing housing, allowing the motor to drive the chuck shaft to rotate. The rubber disc is detachably snapped onto the chuck shaft, allowing the chuck shaft to drive the rubber disc to rotate. A spring is installed between the chuck shaft and the rubber disc, sleeved around the chuck shaft, so that the tension on the rubber disc is transmitted to the chuck shaft. Since the conveying speed of the aforementioned equipment is related to the tension on the rubber disc, this invention's winding mechanism, during winding, allows the tension on the rubber disc to be transmitted to the chuck shaft via the spring, controlling the chuck shaft's rotational speed and thus the winding speed. It eliminates the need for a sensing device, resulting in a simple structure and low manufacturing cost.

[0004] However, in the process of using the above method, the rubber reel used by the device to wind up the U-shaped aluminum buckle tape cannot limit the buckle tape, which means that once the rubber reel is hit, the buckle tape is easy to come off the rubber reel. Utility Model Content

[0005] The purpose of this invention is to provide a plastic reel for U-shaped aluminum buckles, which solves the problem that the plastic reel used in the aforementioned device for winding U-shaped aluminum buckle tape cannot limit the buckle tape, causing the buckle tape to easily detach from the reel once the reel is collided.

[0006] To achieve the above objectives, this utility model provides a plastic reel for U-shaped aluminum buckles, comprising a cylindrical column, a first baffle, a second baffle, and an adjusting device. The first baffle is fixedly mounted on the cylindrical column, and the second baffle is mounted on the cylindrical column via the adjusting device. It also includes a limiting device comprising a limiting block, a guide rod, a push spring, an outer abutment plate, and a moving assembly. The first baffle has a sliding groove, the guide rod is fixedly mounted on the first baffle and located within the sliding groove, the push spring is sleeved on the guide rod and fixedly connected to the first baffle, and the outer abutment plate is slidably mounted on the first baffle via the moving assembly. The limiting block has a through groove, the guide rod passes through the through groove, and the limiting block abuts against the outer abutment plate.

[0007] The movable component includes a movable column and a rotating component. The movable column is fixedly installed on the first baffle and is threadedly engaged with the outer abutment plate. The rotating component is disposed on the outer abutment plate.

[0008] The rotating component includes a rotating convex rod and an anti-slip sleeve. The rotating convex rod is fixedly installed on the outer abutment plate, and the anti-slip sleeve is fixedly installed on the rotating convex rod.

[0009] The adjusting device includes an adjusting column and a rotating protrusion. The adjusting column is threaded into the column cylinder and is also fixedly connected to the second baffle. The rotating protrusion is fixedly installed on the second baffle.

[0010] The second baffle is also provided with placement stripes, which are fixedly installed on the second baffle.

[0011] This utility model discloses a plastic reel for U-shaped aluminum clips. In use, the U-shaped aluminum clip is wound onto the cylindrical tube. After winding, the limiting block is pushed towards one side of the cylindrical tube. Then, the anti-slip sleeve and the rotating convex rod are rotated, causing the rotating convex rod to drive the outer abutment plate to rotate on the moving column. Because the outer abutment plate is threadedly engaged with the moving column, it moves outwards from the moving column during rotation until the limiting block disengages from the outer abutment plate. At this point, the limiting block loses the support of the outer abutment plate. Under the elastic force of the push spring, the limiting block moves along the guide rod and the sliding groove towards the center of the cylindrical tube, thus pressing the clip tape tightly and limiting its position, preventing the clip tape from loosening after winding.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The embodiment of this application is as follows:

[0019] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a plastic reel for a U-shaped aluminum clip according to this utility model. Figure 2 This is a structural schematic diagram of the limiting device of this utility model. Figure 3 This is a schematic diagram of the column and adjusting column of this utility model.

[0020] This utility model provides a plastic reel for U-shaped aluminum buckles: it includes a cylindrical tube 101, a first baffle 102, a second baffle 103, and an adjusting device, and also includes a limiting device. The limiting device includes a limiting block 104, a guide rod 105, a push spring 106, an outer abutment plate 107, and a moving assembly. The moving assembly includes a moving column 110 and a rotating component. The rotating component includes a rotating convex rod 111 and an anti-slip sleeve 112. The adjusting device includes an adjusting column 113 and a rotating convex block 114. The second baffle 103 is also provided with placement stripes 115. The above solution solves the problem that the plastic reel used by the aforementioned device for winding U-shaped aluminum buckle tape cannot limit the buckle tape, causing the buckle tape to easily detach from the plastic reel once it collides with the reel.

[0021] In this embodiment, the moving component drives the outer abutment 107 to disengage from the limiting block 104. The limiting block 104, under the push of the push spring 106, presses the buckle tape to limit the buckle tape and prevent the buckle tape from loosening after loading.

[0022] The first baffle 102 has a sliding groove 108. The guide rod 105 is fixedly installed on the first baffle 102 and located within the sliding groove 108. The push spring 106 is sleeved on the guide rod 105 and fixedly connected to the first baffle 102. The outer abutment 107 is slidably installed on the first baffle 102 via the moving assembly. The limiting block 104 has a through groove 109 through which the guide rod 105 passes. The limiting block 104 abuts against the outer abutment 107. The first baffle 102 and the second baffle 103 are the same size and are both circular. There are six sets of sliding grooves 108, which are distributed in a ring on the first baffle 102. The width of the through groove 109 on the limiting block 104 is equal to the diameter of the guide rod 105. The push spring 106 is located on the side of the limiting block 104 away from the center of the first baffle 102. The inner side of the outer abutment 107 is provided with threads. The end of the column cylinder 101 away from the first baffle 102 is provided with an opening. The inside of the column cylinder 101 is provided with threads. By limiting the column cylinder 101 and the first baffle 102 and the second baffle 103 on both sides, the buckle tape can be wound on the column cylinder 101. By pushing the limiting block 104 to one side of the column cylinder 101, and by moving the outer abutment 107 away from the first baffle 102 through the moving component, the limiting block 104 is disengaged from the outer abutment 107. The limiting block 104, under the push of the push spring 106, presses the buckle tape to achieve the limitation of the buckle tape and prevent the buckle tape from loosening after winding.

[0023] Secondly, the movable column 110 is fixedly installed on the first baffle 102 and threadedly engaged with the outer abutment 107; the rotating component is disposed on the outer abutment 107, the axis of the movable column 110 coincides with that of the first baffle 102, the movable column 110 is provided with threads, and the outer abutment 107 is rotated by the rotating component, so that the outer abutment 107 moves by threading with the movable column 110.

[0024] Furthermore, the rotating protrusion 111 is fixedly installed on the outer abutment plate 107; the anti-slip sleeve 112 is fixedly installed on the rotating protrusion 111. The rotating protrusion 111 is located at an eccentric position on the outer abutment plate 107. The anti-slip sleeve 112 is bonded to the outside of the rotating protrusion 111. The anti-slip sleeve 112 is made of rubber. By rotating the rotating protrusion 111, the outer abutment plate 107 rotates, thereby realizing the rotational drive of the outer abutment plate 107.

[0025] Furthermore, the adjusting column 113 is threadedly engaged with the column cylinder 101, and the adjusting column 113 is also fixedly connected to the second baffle 103; the rotating protrusion 114 is fixedly installed on the second baffle 103. The adjusting column 113 has a cylindrical structure, and the axis of the adjusting column 113 coincides with the axis of the column cylinder 101. The adjusting column 113 has a thread on its outer side. The rotating protrusion 114 has an arc-shaped structure, and there are multiple sets of them, which are arranged in a ring around the outer periphery of the second baffle 103. The rotating protrusion 114 drives the second baffle 103 to rotate, so that the second baffle 103 drives the adjusting column 113 to rotate. Since the adjusting column 113 is threadedly engaged with the column cylinder 101, the adjusting column 113 will move outward from the main cylinder when rotating, and drive the first baffle 102 away from the first baffle 102, thereby extending the winding length of the column cylinder 101 for the buckle tape.

[0026] Finally, the placement stripe 115 is fixedly installed on the second baffle 103. The placement stripe 115 is made of plastic and is fixed to the outside of the second baffle 103 by welding. The placement stripe 115 makes the placement of the second baffle 103 more stable.

[0027] In this embodiment, during use, the U-shaped aluminum buckle is wound onto the column 101. After winding, the limiting block 104 is pushed toward one side of the column 101. Then, the anti-slip sleeve 112 and the rotating protrusion 111 are rotated, causing the rotating protrusion 111 to drive the outer abutment 107 to rotate on the moving column 110. Since the outer abutment 107 is threadedly engaged with the moving column 110, the outer abutment 107 rotates toward the moving column 110. The moving column 110 moves outward until the limiting block 104 disengages from the outer abutment plate 107. At this time, the limiting block 104 loses the support of the outer abutment plate 107. Under the elastic force of the push spring 106, the limiting block 104 moves along the guide rod 105 and the slide groove 108 toward the center of the column cylinder 101, so that the limiting block 104 presses the buckle tape tightly, thereby limiting the buckle tape and preventing the buckle tape from loosening after loading.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
