Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a number tube feeding mechanism. Background Art

[0002] Number tubes, also known as line number tubes, are tubing used for wiring identification, typically made of PVC. They are suitable for various electrical wiring, troubleshooting, and maintenance tasks, ensuring proper wiring and avoiding complications during troubleshooting and maintenance. Number tube printers are devices that print recognizable numbers and letters on number tubes, primarily used to produce number tubes or labels. To accommodate continuous printing, existing number tube printers typically pull the number tubes from a tray into the printer at a constant speed, maintaining a constant tension to complete the printing process.

[0003] However, since the number tube is made of flexible plastic, it is easily affected by the external environment, resulting in unstable feeding tension. When the number tube is pulled by the number tube printer, the tensile deformation of the number tube will be different, which will lead to inconsistent lengths of the number tube after printing, affecting the printing effect of the number tube. This solution solves this technical problem. Utility Model Content

[0004] In response to the deficiencies of the prior art, the utility model provides a number tube feeding mechanism. By stretching the connection between a stabilizing component and a traction component, when the number tube is subjected to excessive tension, the traction component increases the number tube feeding speed; when the number tube is subjected to excessive tension, the traction component reduces the number tube feeding speed, thereby ensuring the stability of the tension applied to the number tube and avoiding the phenomenon of inconsistent printed lengths of the number tube caused by unstable tension on the number tube when the number tube printer is printing the number tube, thereby improving the printing effect of the number tube printer.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a number tube feeding mechanism, comprising a support frame, a material tray rotatably mounted on the support frame, the material tray having number tubes wound thereon, a traction assembly for pulling the number tubes, and a stretching and stabilizing assembly for adjusting the tension of the number tubes. The number tubes on the material tray sequentially pass through the traction assembly and the stretching and stabilizing assembly, and are then pulled by the number tube printer and printed.

[0006] The stretching stabilization assembly includes a slide rail vertically arranged on the support frame, a counterweight slider slidingly arranged on the slide rail, an upper sensor and a lower sensor for detecting the upper and lower limit positions of the counterweight slider, and a movable pulley rotatably arranged on the counterweight slider. The number tube is arranged to bypass the movable pulley. The upper sensor and the lower sensor are electrically connected to the traction assembly through a controller.

[0007] The traction assembly includes a motor fixedly mounted on the support frame, a driving wheel connected to an output shaft of the motor, the number tube being arranged around the driving wheel, a pressure wheel for pressing the number tube on the driving wheel being arranged on the side of the driving wheel, and the motor being electrically connected to the controller.

[0008] There are two slide rails, both of which are vertically arranged on the bottom side of the support frame, a load-bearing plate is connected between the two counterweight sliders, the movable pulley is rotatably arranged on the load-bearing plate, a vertical support is arranged on the side of the load-bearing plate, the upper sensor and the lower sensor are both arranged on the vertical support, and the upper sensor and the lower sensor are both arranged facing the load-bearing plate.

[0009] A heating component for heating the number tube is provided between the stretching stabilization component and the number tube printer. The number tube passes through the heating component. A temperature control module connected to the heating component is provided on the support frame.

[0010] A guide wheel for adjusting the direction of the number tube is provided on the support frame between the heating component and the traction component, and the number tube is provided to bypass the guide wheel.

[0011] A pendulum block is provided on the support frame, one end of the pendulum block is swung on the support frame through a rotating shaft, the pressure wheel is rotatably provided on the pendulum block, the other end of the pendulum block and the support frame are provided with a tension spring, one end of the tension spring is connected to the support frame, and the other end of the tension spring is connected to the other end of the pendulum block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) By connecting the stretching stabilizing component and the traction component, when the tension on the number tube is too large, the traction component increases the feeding speed of the number tube, and when the tension on the number tube is too small, the traction component reduces the feeding speed of the number tube, thereby ensuring the stability of the tension on the number tube and avoiding the phenomenon that the tension on the number tube is unstable when the number tube printer prints the number tube, resulting in inconsistent printing length of the number tube, thereby improving the printing effect of the number tube printer;

[0015] (2) The temperature control module controls the heating component to heat the number tube. When the temperature is too low, the heating of the number tube makes the number tube printer have a better pulling effect on the number tube, further improving the number tube printing effect;

[0030] A connecting plate 58 is provided between the free ends of the two slide rails 51 to make the operation of the counterweight slider 52 more stable.

[0031] The specific working process and principle of this utility model:

[0032] The feeding mechanism is installed at the feeding position of the number tube printer 6 through the support frame 1. The number tubes 3 on the feed tray 2 are driven by the pressure wheel 43 of the traction assembly 4, pass between the driving wheel 42 and the pressure wheel 43, and bypass the movable pulley 55 of the stretching and stabilizing assembly 5. After being heated by the guide wheel 9 and the heating assembly 7, they are pulled and printed at a constant speed by the number tube printer 6. When the number tube printer 6 pulls the number tubes 3, for the stretching and stabilizing assembly 5, the number tubes 3 drive the counterweight slider 52 to rise along the slide rail 51 through the movable pulley 55. When the counterweight slider 52 rises to the position of the carrier plate 56 and the upper sensor 53, it is said that It is clear that the tension on the number tube 3 is too great, and the upper sensor 53 sends a command to the motor 41 through the controller. The motor 41 drives the driving wheel 42 to rotate, so that the driving wheel 42 and the pressure wheel 43 draw the number tube 3 from the material tray 2 to avoid excessive tension on the number tube 3. When the movable pulley 55 drives the counterweight slider 52 to descend to the supporting plate 56 and reach the position of the lower sensor 54, it means that the tension on the number tube 3 is too small. The lower sensor 54 sends a command to the motor 41 through the controller to reduce the speed of the motor 41, thereby reducing the extraction speed of the number tube 3 and increasing the tension on the number tube 3, making the feeding of the number tube 3 more stable and reliable.

[0033] By connecting the stretching stabilizing component 5 with the pulling component 4, when the tension on the number tube 3 is too large, the pulling component 4 increases the feeding speed of the number tube 3; when the tension on the number tube 3 is too small, the pulling component 4 reduces the feeding speed of the number tube 3. This ensures that the tension on the number tube 3 is stable, avoids the phenomenon of inconsistent printing length of the number tube 3 caused by unstable tension on the number tube 3 by the number tube printer 6 when printing the number tube 3, and improves the printing effect of the number tube printer 6.

[0034] The temperature control module 8 controls the heating component 7 to heat the number tube 3. When the temperature is too low, the heating of the number tube 3 allows the number tube printer 6 to better pull the number tube 3, further improving the printing effect of the number tube 3.

[0035] In the traction assembly 4 , the tension spring 45 drives the pressing wheel 43 on the pendulum block 44 to press the number tube 3 , so that the driving wheel 42 in the traction assembly 4 can more stably traction and convey the number tube 3 .

[0036] The heating assembly 7 contains a heating wire for heating the number tube 3. When the number tube 3 passes through the heating assembly 7, it is heated by the heating wire. The heating assembly 7 contains a temperature sensor connected to the temperature control module 8. The temperature of the number tube 3 is monitored by the temperature sensor, and the power supplied to the heating wire is adjusted by the temperature control module 8, thereby stabilizing the temperature of the number tube 3.
