Description

Technical Field

[0001] This utility model relates to the field of carbon ribbon tension protection technology, and more specifically to a carbon ribbon segment tension control device. Background Technology

[0002] A ribbon is a consumable used in printing equipment. Its main body is strip-shaped, with one side coated with a polyester film containing wax-based, resin-based, or mixed inks, and the other side coated with a lubricant to prevent wear on the print head. Under the heat and pressure of the print head of the barcode printer, the ink on the ribbon transfers the corresponding text and barcode information onto the label to complete the printing process.

[0003] Currently, there is a lack of structures to adjust the tension of the ribbon during the ribbon printing process. This makes it easy for the ribbon to have uneven tension during printing. When the tension is too low, the ribbon is prone to loosening, affecting the printing accuracy. When the tension is too high, the ribbon is prone to breaking, affecting the normal use of the printing equipment.

[0004] In view of this, the present invention proposes a carbon ribbon segment tension control device to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a carbon ribbon segment tension control device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a carbon ribbon segment tension control device, including a housing, wherein a carbon ribbon take-up shaft, a carbon ribbon unwinding shaft and two guide shafts are rotatably connected to the inner wall of the housing, carbon ribbon strips are wound on the surfaces of the carbon ribbon take-up shaft and the carbon ribbon unwinding shaft, and the carbon ribbon strips are laid on the surfaces of the two guide shafts, wherein the carbon ribbon take-up shaft and the carbon ribbon unwinding shaft are used for taking up and unwinding the carbon ribbon strips respectively, and tension adjustment components are provided on both sides of the guide shafts corresponding to the carbon ribbon strips on the inner wall of the housing;

[0007] The tension adjustment assembly includes two beams symmetrically fixedly installed on the inner wall of the housing. Hydraulic telescopic rods are embedded in the surfaces of both beams. A connecting plate is fixedly installed at the telescopic end of each hydraulic telescopic rod. A telescopic cylinder is fixedly installed on the surface of the connecting plate. A telescopic column is slidably connected to the end of the telescopic cylinder away from the connecting plate. A support spring for driving the telescopic column to move outward is fixedly installed on the inner wall of the telescopic cylinder. A first pressure sensor and a second pressure sensor are fixedly installed on the inner wall of the telescopic cylinder, respectively. A contact plate is fixedly installed at one end of the telescopic column inside the telescopic cylinder, with the contact plate corresponding to the sensing ends of the first and second pressure sensors. A support frame is fixedly installed at the end of the telescopic column away from the telescopic cylinder. A support roller is rotatably connected to the surface of the support frame, and the surface of the support roller abuts against the carbon fiber strip.

[0008] Furthermore, a controller is fixedly installed on the front of the housing, and the controller is electrically connected to an external power source through wires; two servo motors are fixedly installed on the outer wall of the housing, and the output shafts of the two servo motors are coaxially fixed with the ribbon take-up shaft and the ribbon unwind shaft, respectively.

[0009] As a further description of the above technical solution: through the precise control of the servo motor by the controller, the carbon ribbon take-up shaft and the carbon ribbon unwind shaft can operate synchronously and smoothly, thereby ensuring the stability of the carbon ribbon tension during transmission.

[0010] Furthermore, a first limiting slide rod is fixedly installed on the surface of the connecting plate, and the first limiting slide rod is inserted into the surface of the beam frame.

[0011] As a further description of the above technical solution: by setting a first limit slide bar, the connecting plate can move in a stable linear motion during the extension and retraction of the hydraulic telescopic rod, thus avoiding shaking of the connecting plate.

[0012] Furthermore, a second limiting slide rod is fixedly installed on the surface of the support frame, and the second limiting slide rod is inserted into the surface of the connecting plate.

[0013] As a further description of the above technical solution: by setting a second limiting slide bar, the movement of the support frame can be limited, so that the support frame can move in a stable straight line during the extension and retraction of the telescopic column, avoiding the support frame from shaking, thereby improving the stability of the device.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with existing technologies, this ribbon segment tension control device utilizes a servo motor to drive the ribbon take-up and unwrap shafts to rotate and wind the ribbon for use by external printing equipment. During the ribbon transport process, a tension adjustment component is set up so that the ribbon squeezes the support rollers according to design requirements, thereby driving the support springs to compress. This positions the contact plate between the first and second pressure sensors, maintaining the tension as required by the design. When the contact plate contacts either the first or second pressure sensor, a signal is fed back to the controller, which controls the extension and retraction of the hydraulic telescopic rod to actively adjust the position of the support rollers and adjust the tension of the ribbon segments. This ensures stable tension of the ribbon during transport, preventing ribbon slack or breakage, and further improving printing accuracy and equipment stability.

[0016] 2. Compared with the prior art, this carbon belt segment tension control device, by setting a first limiting slide bar, enables the connecting plate to move stably in a straight line during the extension and retraction of the hydraulic telescopic rod, thus preventing the connecting plate from shaking; by setting a second limiting slide bar, the movement of the support frame can be limited, enabling the support frame to move stably in a straight line during the extension and retraction of the telescopic column, thus preventing the support frame from shaking, thereby improving the stability of the device.

[0023] The inner wall of the housing 1 is rotatably connected to a ribbon take-up shaft 2, a ribbon unwind shaft 3, and two guide shafts 4. The outer wall of the housing 1 is fixedly installed with two servo motors 18, and the output shafts of the two servo motors 18 are coaxially fixed with the ribbon take-up shaft 2 and the ribbon unwind shaft 3, respectively.

[0024] Carbon ribbon 5 is wound around the surfaces of the carbon ribbon take-up shaft 2 and the carbon ribbon unwind shaft 3. The carbon ribbon 5 is laid on the surfaces of the two guide shafts 4. The carbon ribbon take-up shaft 2 and the carbon ribbon unwind shaft 3 are used for taking up and unwinding the carbon ribbon 5, respectively.

[0025] The precise control of the servo motor 18 by the controller 17 enables the ribbon take-up shaft 2 and the ribbon unwind shaft 3 to operate synchronously and smoothly, thereby ensuring the stable tension of the ribbon 5 during transmission, so that the ribbon 5 can be used by external printing equipment.

[0026] Tension adjustment components are provided on both sides of the guide shaft 4 on the inner wall of the housing 1, corresponding to the carbon belt 5.

[0027] The tension adjustment assembly includes two beams 6 symmetrically fixedly installed on the inner wall of the housing 1. The surfaces of the two beams 6 are each fitted with a hydraulic telescopic rod 7, and the telescopic ends of the hydraulic telescopic rods 7 are fixedly installed with connecting plates 8.

[0028] A telescopic cylinder 9 is fixedly installed on the surface of the connecting plate 8.

[0030] During the conveying process of the carbon ribbon 5, by setting up a tension adjustment component, the carbon ribbon 5 squeezes the support roller 16 according to the design requirements, thereby driving the support spring 11 to compress, so that the contact plate 14 is located between the first pressure sensor 12 and the second pressure sensor 13, maintaining the tension in accordance with the design requirements. When the contact plate 14 contacts the first pressure sensor 12 or the second pressure sensor 13, it feeds a signal back to the controller 17, which can control the extension and retraction of the hydraulic telescopic rod 7 to actively adjust the position of the support roller 16 and adjust the tension of the carbon ribbon 5 in segments, thereby ensuring the tension of the carbon ribbon 5 is stable during the conveying process, avoiding the occurrence of loosening or breakage of the carbon ribbon 5, and further improving the printing accuracy and equipment stability.
