[0001] This utility model belongs to the field of thread reel technology, specifically relating to a thread reel with counting function. Background Technology

[0002] Cable reels are widely used as an important auxiliary tool in various industries during the storage, transportation, and use of wires, cables, optical fibers, and other cables.

[0003] Traditional cable reels primarily function to wind and store cables for easy organization and transport. However, in practical applications, users often need to measure the length of the cables to meet specific application requirements.

[0004] Currently, most cable reels on the market lack a counting function. When users need to measure cable length, they typically rely on manual measurement or external measuring tools. This method is not only cumbersome and inefficient, but also prone to introducing measurement errors, affecting the accuracy and reliability of cable use.

[0005] Therefore, in order to solve the above problems, it is necessary to design a spool with counting function. Utility Model Content

[0006] The purpose of this invention is to provide a thread reel with a counting function to solve the technical problem that existing thread reels cannot count.

[0007] To solve the above-mentioned technical problems, this utility model provides a spool with a counting function, comprising:

[0008] Base support and drum connected to the bearing of the base support;

[0009] The counting assembly includes: a U-shaped component mounted on a base support, a roller connected to a bearing of the U-shaped component, a magnetic component mounted on the roller, and a Hall sensor mounted on the side of the U-shaped component; wherein...

[0010] The roller is adapted to contact the cable so as to drive the roller to rotate when the cable is being wound up or unwound;

[0011] The Hall sensor is coupled to a magnetic component and converts the magnetic field changes generated when the magnetic component rotates into electrical signals and uploads them.

[0012] The display screen is mounted on the base bracket;

[0013] The main control module is electrically connected to the Hall sensor and communicatively connected to the display screen.

[0014] The main control module is adapted to calculate the number of rotations of the roller based on the number of electrical signals uploaded by the Hall sensor, so as to obtain the cable take-up or take-out length and display it on the display screen.

[0015] Furthermore, the counting assembly also includes: a first rotating shaft connected to a U-shaped bearing; wherein

[0016] The roller is sleeved on the first rotating shaft; and

[0017] The magnetic component is mounted on the first rotating shaft.

[0018] Furthermore, the roller has an annular recess; wherein

[0019] The annular recess is adapted to contact the cable.

[0020] Furthermore, the base support is provided with two upright plates;

[0021] Two second pivots are provided between the two upright plates; wherein

[0022] The two second rotating shafts are connected to the two vertical plate bearings;

[0023] The second rotating shaft is fitted with a first sleeve; and

[0024] The first sleeve is adapted to longitudinally limit the cable so that the cable can make tight contact with the annular recess.

[0025] Furthermore, the base support is provided with two third rotating shafts; wherein

[0026] A second sleeve is fitted onto the third rotating shaft; wherein

[0027] The second sleeve is connected to the third shaft bearing;

[0028] The second sleeve is adapted to laterally limit the cable so that the cable can make tight contact with the annular recess.

[0029] The beneficial effects of this utility model are:

[0030] (i) When the cable is being wound up or unwound on the reel, the cable contacts the roller, and the friction causes the roller to rotate. The magnetic component follows the rotation of the roller and generates a change in magnetic field. The Hall sensor detects the change in magnetic field, converts it into an electrical signal, and uploads it to the main control module. The main control module calculates the number of rotations of the roller based on the number of received electrical signals, and then determines the length of the cable wound up or unwound. The result is displayed on the screen. Through the cooperation of the Hall sensor and the main control module, the length of the cable can be accurately measured, avoiding errors caused by manual measurement or the use of external measuring tools. At the same time, the cable length can be measured during the winding or unwinding of the reel without additional operation, which greatly improves work efficiency.

[0042] like Figures 1 to 3As shown, this embodiment provides a coil with a counting function, including:

[0043] The system comprises: a base support 1 and a reel 2 connected to the base support 1 via a bearing; a counting assembly 3, comprising: a U-shaped component 301 mounted on the base support 1, a roller 302 connected to the U-shaped component 301 via a bearing, a magnetic component 303 mounted on the roller 302, and a Hall sensor 304 mounted on the side of the U-shaped component 301; wherein the roller 302 is adapted to contact the cable to rotate during cable winding or unwinding; the Hall sensor 304 is coupled to the magnetic component 303 and converts the magnetic field change generated by the rotation of the magnetic component 303 into an electrical signal and uploads it; a display screen 4 mounted on the base support 1; and a main control module electrically connected to the Hall sensor 304 and communicatively connected to the display screen 4; wherein the main control module is adapted to calculate the number of rotations of the roller 302 based on the number of electrical signals uploaded by the Hall sensor 304 to determine the cable winding or unwinding length and display it on the display screen 4; wherein the main control module uses, but is not limited to, an MCU; and wherein the magnetic component 303 uses, but is not limited to, a magnetic ring.

[0044] In this embodiment, when the cable is wound up or unwound on the reel 2, the cable contacts the roller 302. Under the action of friction, the roller 302 rotates. The magnetic component 303 rotates with the roller 302 and generates a change in magnetic field. After the Hall sensor 304 senses the change in magnetic field, it converts it into an electrical signal and uploads it to the main control module. The main control module calculates the number of rotations of the roller 302 based on the number of received electrical signals, and then obtains the length of the cable wound up or unwound. The result is displayed on the display screen 4. Through the cooperation of the Hall sensor 304 and the main control module, the length of the cable can be accurately measured, avoiding the errors caused by manual measurement or the use of external measuring tools. At the same time, the cable length can be measured when the reel 2 is wound up or unwound, without additional operation, which greatly improves work efficiency.

[0045] The counting component 3 further includes: a first rotating shaft 305 connected to the bearing of the U-shaped component 301; wherein the roller 302 is sleeved on the first rotating shaft 305; and the magnetic component 303 is disposed on the first rotating shaft 305; wherein the first rotating shaft 305 is connected to the bearing of the U-shaped component 301, thereby reducing friction and ensuring smooth rotation of the roller 302.

[0046] The roller 302 has an annular recess 3021; ​​the annular recess 3021 is suitable for contacting the cable; by setting the annular recess 3021, the contact area with the cable is increased, making the counting results more accurate, and it can also be adapted to cables of various diameters.

[0047] The base support 1 is provided with two upright plates 5; two second rotating shafts 6 are provided between the two upright plates 5; wherein the two second rotating shafts 6 are connected to the two upright plates 5 by bearings; a first sleeve 7 is sleeved on the second rotating shaft 6; and the two first sleeves 7 are adapted to limit the longitudinal movement of the cable so that the cable can be in close contact with the annular recess 3021; ​​wherein the connection between the second rotating shaft 6 and the two upright plates 5 by bearings reduces the friction and wear of the cable when the cable contacts the first sleeve 7.

[0048] The base bracket 1 is provided with two third rotating shafts 8; wherein a second sleeve 9 is sleeved on the third rotating shaft 8; wherein the second sleeve 9 is connected to the bearing of the third rotating shaft 8; the two second sleeves 9 are adapted to limit the cable laterally so that the cable can be in close contact with the annular recess 3021; ​​wherein the connection between the second sleeve 9 and the bearing of the third rotating shaft 8 reduces the friction and wear of the cable when the cable contacts the second sleeve 9.

[0049] In this embodiment, the longitudinal limiting of the two first sleeves 7 and the lateral limiting of the two second sleeves 9 ensure that the cable is in a straight line with the roller 302 when it is being wound up and unwound, and ensure that the cable can be in close contact with the annular recess 3021 of the roller 302, reducing cable slippage or deviation and improving the accuracy of counting.
