Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging reels, in particular to a plastic reel used for carrier tape winding packaging. Background Art
[0002] Carrier tape, also known as surface mount carrier tape, is mainly used as a plastic carrier for packaging SMT electronic components such as resistors, inductors, capacitors, connectors, LEDs, fuses, switches, relays, connectors, oscillators, diodes, transistors, mobile phone shielding frames, etc. The current carrier tape is generally packaged in a multi-layer winding type when it leaves the factory. The paper packaging reel used in the traditional multi-layer winding type packaging has low strength and is prone to loose rolls.
[0003] The existing authorized patent CN219031364U discloses a multi-layered antistatic packaging reel for surface mount carrier tape, which is packaged and wound using an axis core and a reel surface made of antistatic plastic, thereby ensuring the overall use height and service life.
[0004] However, when the above-mentioned method is used, since the reels on both sides of the reel are fixed in advance, it is easy for the winding thickness to be too high or too low for the two fixed reels with different numbers of carriers, thereby affecting the subsequent transportation and loading. It is impossible to adjust the winding width of the reel according to the actual winding quantity in actual use, which is very inconvenient in actual use. Utility Model Content
[0005] The utility model aims to provide a plastic reel for carrier tape wrapping packaging, which can adjust the winding width of the plastic reel according to actual operating conditions through a component provided, so that it is more convenient and flexible in actual use.
[0006] To achieve the above-mentioned purpose, the utility model provides a plastic reel for carrier tape wrapping packaging, comprising a fixed core column and a fixed disk, and also comprising an adjustment component;
[0007] The adjustment assembly includes a movable core column, an adjustment disk, an adjustment screw, a driving component and a shielding component; the movable core column is slidably connected to the fixed core column and is located on one side of the fixed core column, the adjustment disk is fixedly connected to the movable core column and sleeved on the movable core column, the adjustment screw is threadedly connected to the fixed core column and rotatably installed on the movable core column, the driving component is connected to the adjustment screw, and the shielding component is connected to the movable core column.
[0008] Among them, the driving component includes a rotating column, a limit plug, an extrusion spring and a toggle component. The rotating column is fixedly connected to the adjusting screw and is rotatably installed on one side of the movable core column; the limit plug is slidably connected to the rotating column and is connected to the movable core column; the two sides of the extrusion spring are respectively connected to the limit plug and the rotating column; the toggle component is connected to the limit plug.
[0009] Among them, the toggle component includes a connecting frame, an arc groove guide block and a holding column, the connecting frame is fixedly connected to the limit plug block and is located on one side of the limit plug block; the arc groove guide block is fixedly connected to the connecting frame and is located on one side of the connecting frame; the holding column is connected to the rotating column and is installed on the arc groove guide block.
[0010] Wherein, the rotating column has an installation slot and a matching arc slot, the installation slot is located on a side of the rotating column close to the limiting plug; the matching arc slot is located on a side of the rotating column close to the holding column.
[0011] Wherein, the shielding component includes a sleeve cover and an elastic limiting ring, the sleeve cover is connected to the movable core column and is located on a side of the movable core column close to the rotating column; the elastic limiting ring is fixedly connected to the sleeve cover and is located on one side of the sleeve cover.
[0012] The utility model discloses a plastic reel for carrying tape winding packaging, wherein the arc groove guide block and the connecting frame are driven to slide by toggling the holding column, thereby driving the limit plug block to slide on the rotating column through the connecting frame; when the limit plug block is disengaged from the insertion groove provided on the movable core column, the user can rotate the rotating column and the adjusting screw by toggling the holding column; when the rotating column is driven to rotate by the holding column, since the holding column can be rotated in a corresponding direction in advance by the cooperation between the arc groove guide block and the matching arc groove, the force applied to the holding column will be reduced when the user only rotates a part of the direction. After the force on the handle is removed, the holding column can still maintain a stable position through the cooperation with the arc groove guide block and the matching arc groove, which is convenient for the user to drive the rotating column later. Moreover, the user only needs to apply a force in a circumferential direction when driving through the holding column, and there is no need to specially pull the holding column to rotate. When the rotating column drives the adjusting screw to rotate, the movable core column can slide relative to the fixed core column, thereby completing the adjustment of the reel winding width. After the entire adjustment is completed, the user can first move the holding column to the middle end of the matching arc groove, so that the limit block in the rotating column is just in contact with the movable core column. When the insertion slot of the movable core column matches the insertion slot position of the movable core column, the extrusion spring will drive the limit plug, the connecting frame, the arc groove guide block and the holding column provided on the connecting frame to slide and reset, thereby limiting the rotating column accordingly to ensure the stability of the position of the movable core column and the fixed core column. When the limit plug is not aligned with the insertion slot position of the movable core column, the user only needs to slightly move the holding column to make the rotating column partially adjust the angle to match the limit plug with the insertion slot of the movable core column. At the same time, in order to ensure that the holding column can be moved to the middle end of the matching arc groove when the limit block cannot be ejected normally, The whole rotating column can be driven, so the matching arc groove will be set relatively outside, and when the user pulls the holding column to the position corresponding to the matching arc groove, the limit plug will be retracted into a part of the rotating column through the pulling of the holding column. Therefore, when the user moves the holding column to the middle end of the matching arc groove, even if the limit plug cannot be fully ejected normally, it will also drive the holding column to move a distance, so that the holding column is matched with the vertical groove at the middle end of the matching arc groove, thereby realizing the corresponding adjustment of the winding width of the plastic reel according to the actual operating conditions through the provided components, which makes it more convenient and flexible in actual use.

[0026] In this embodiment, the fixed disk 102 is fixedly mounted on the fixed core column 101, and the side of the fixed core column 101 is provided with an embedding hole for cooperating with a rotating device, so that the entire reel can be driven to rotate through a rotating clamping mechanism provided externally.
[0027] The movable stem 103 is slidably connected to the fixed stem 101 and is located on one side of the fixed stem 101. The adjusting disk 104 is fixedly connected to the movable stem 103 and sleeved on the movable stem 103. The adjusting screw 105 is threadedly connected to the fixed stem 101 and rotatably mounted on the movable stem 103. The driving member is connected to the adjusting screw 105. The shielding member is connected to the movable stem 103. The movable stem 103 is connected to the fixed stem through a connecting boss provided on the side. 101 is slidingly connected, and an embedding hole matching the fixed core column 101 is provided on the outer side of the movable core column 103, so that the entire reel can be driven to rotate through the corresponding mechanism, and the adjusting screw 105 is installed in the connecting boss of the movable core column 103, and the adjusting screw 105 matches the threaded hole provided on the side of the fixed core column 101, so that the user can directly drive the adjusting screw 105 to drive the fixed core column 101 to move on the movable core column 103, thereby changing the clamping width of the discs on the two core columns.
[0028] Secondly, the rotating column 106 is fixedly connected to the adjusting screw 105 and is rotatably mounted on one side of the movable core column 103; the limiting plug 107 is slidably connected to the rotating column 106 and is connected to the movable core column 103; the two sides of the extrusion spring 108 are respectively connected to the limiting plug 107 and the rotating column 106; the toggle component is connected to the limiting plug 107, and the connecting frame 109 is fixedly connected to the limiting plug 107 and is located on one side of the limiting plug 107; the arc groove guide block 110 is fixedly connected to the connecting frame 109 and is located on one side of the connecting frame 109; the holding column 111 is connected to the rotating column 106 and is mounted on the arc groove guide On the block 110, the installation slot 112 is located on the side of the rotating column 106 close to the limiting plug block 107; the matching arc groove 113 is located on the side of the rotating column 106 close to the holding column 111, the rotating column 106 is fixedly arranged on one side of the adjusting screw 105, and the rotating column 106 is also rotatably installed on one side of the movable core column 103, the limiting plug block 107 matches the installation slot 112 provided on the rotating column 106, the boss provided on the end of the limiting plug block 107 matches the multiple insertion grooves evenly distributed on the inner wall of the movable core column 103, and the extrusion spring 108 is also installed between the back of the limiting plug block 107 and the inner wall of the installation slot 112. When the end boss of the limiting plug 107 corresponds to the insertion groove provided inside the movable stem 103, the extrusion spring 108 will drive the limiting plug 107 to cooperate with the insertion groove of the movable stem 103, so as to complete the limiting between the rotating column 106 and the movable stem 103. The connecting frame 109 is fixed to the top of the limiting plug 107, and the arc groove guide block 110 is fixed to the end of the connecting frame 109. The holding column 111 is slidably installed on the arc groove guide block 110. The holding column 111 cooperates with the guide rail boss of the arc groove guide block 110 through the internal inner groove, so that the holding column 111 can slide accordingly under the guidance of the arc groove of the arc groove guide block 110. At the same time, the end of the rotating column 106 is also provided with the matching arc groove 113 for matching with the holding column 111, and a vertical groove for the holding column 111 to slide is provided above the matching arc groove 113. When the user needs to drive the rotating column 106 and the adjusting screw 105, the holding column 111 can be pulled first, and then the arc groove guide block 110, the connecting frame 109 and the limiting plug block 107 are driven to move by the holding column 111. The holding column 111 first slides linearly through the vertical groove above the matching arc groove 113. After the holding column 111 slides to the center of the matching arc groove 113, the user can toggle the holding column 111.The holding column 111 is partially rotated along the arc groove of the arc groove guide block 110 and the specified direction of the matching arc groove 113. When the holding column 111 is rotated to the end of the arc groove of the arc groove guide block 110, the user can drive the rotating column 106 and the adjusting screw 105 to rotate on the movable core column 103 by turning the holding column 111. Therefore, the limiting plug 107 is completely retracted into the rotating column 106 by pulling the holding column 111, so that the rotating column 106 can be moved on the movable core column 103. When the rotating column 106 needs to be limited again, it is only necessary to first move the holding column 111 to the middle end of the matching arc groove 113. In this way, when the limiting plug 107 on the rotating column 106 cooperates with the insertion groove provided on the movable core column 103, the extrusion spring 108 will drive the limiting plug 107 and the connecting frame 109 to slide, so that the limiting plug 107 cooperates with the insertion groove. At this time, the holding column 111 on the arc groove guide block 110 will also slide accordingly under the guidance of the connecting frame 109.
[0029] When the plastic reel for carrier tape winding packaging of the present embodiment is in use, the arc groove guide block 110 and the connecting frame 109 are driven to slide by toggling the holding column 111, so that the limiting plug block 107 is driven to slide on the rotating column 106 through the connecting frame 109. When the limiting plug block 107 is disengaged from the insertion groove provided on the movable core column 103, the user can rotate the rotating column 106 and the adjusting screw 105 by toggling the holding column 111. When the rotating column 106 is driven to rotate by the holding column 111, the holding column 111 can be moved in advance toward the rotating column 106 through the cooperation between the arc groove guide block 110 and the matching arc groove 113. Therefore, when the user only rotates a part and removes the force applied to the holding column 111, the holding column 111 can still maintain a stable position through the cooperation with the arc groove guide block 110 and the matching arc groove 113, which is convenient for the user to drive the rotating column 106 later. Moreover, when the user drives through the holding column 111, he only needs to apply a force in a circumferential direction and does not need to specially pull the holding column 111 to rotate. When the rotating column 106 drives the adjusting screw 105 to rotate, the movable core column 103 can slide relative to the fixed core column 101, thereby completing the adjustment of the reel winding width. After the entire adjustment is completed, the user can The holding column 111 is moved to the middle end of the matching arc groove 113. When the limiting block 107 in the rotating column 106 just matches the insertion slot position of the movable stem 103, the extrusion spring 108 will drive the limiting block 107 and the connecting frame 109 as well as the arc groove guide block 110 and the holding column 111 to slide and reset, thereby correspondingly limiting the rotating column 106 to ensure the stability of the position of the movable stem 103 and the fixed stem 101. When the limiting block 107 is not aligned with the insertion slot position of the movable stem 103, the user only needs to slightly move the holding column 111 to make the rotating column 106 move. The limiting plug 107 can be matched with the insertion slot of the movable core column 103 by adjusting the angle. At the same time, in order to ensure that the holding column 111 can still drive the entire rotating column 106 when it is moved to the middle end of the matching arc groove 113 when the limiting plug 107 cannot be ejected normally, the matching arc groove 113 is set relatively far to the outside. When the user pulls the holding column 111 to the position corresponding to the matching arc groove 113, the limiting plug 107 will be retracted into a part of the rotating column 106 by the pulling of the holding column 111. Therefore, when the user moves the holding column 111 to the middle end of the matching arc groove 113, even if the limiting plug 107 cannot be ejected completely normally,It will also drive the holding column 111 to move a certain distance, so that the holding column 111 cooperates with the vertical groove at the middle end of the matching arc groove 113, so that the winding width of the plastic reel can be adjusted according to the actual operation situation through the provided components, making it more convenient and flexible in actual use.

Figure 7 This is a schematic structural diagram of the second embodiment with the sleeve cover 201 removed. The shielding component provided by the utility model includes the sleeve cover 201 and an elastic limiting ring 202.
[0032] Among them, the sleeve cover 201 is connected to the movable core column 103 and is located on a side of the movable core column 103 close to the rotating column 106; the elastic limiting ring 202 is fixedly connected to the sleeve cover 201 and is located on one side of the sleeve cover 201, the sleeve cover 201 matches the mounting hole of the movable core column 103 for mounting the rotating column 106, and the outer ring of the sleeve cover 201 is provided with two elastic limiting rings 202, and the elastic limiting rings 202 are made of elastic rubber. The movable core column 103 is provided with an annular groove matching the elastic limiting ring 202 on the inner wall of the mounting hole matching the rotating column 106, so that after the user completely installs the sleeve cover 201 into the mounting hole, it can be limited by the cooperation between the elastic limiting ring 202 and the annular groove in the mounting hole.
[0033] When using a plastic reel for carrier tape wrapping packaging according to the present embodiment, the sleeve cover 201 can be used to shield and protect the rotating column 106 on the side of the movable core column 103 and the mechanism provided on the outside of the rotating column 106 to avoid accidental touching or collision. At the same time, the sleeve cover 201 can also be limited to a certain extent by the elastic limiting ring 202, thereby ensuring the stability of the protection of the entire shielding area, greatly enhancing the practicality of the entire device.
