Description

Technical Field

[0001] The utility model relates to the technical field of ribbon processing, in particular to an automatic alarm and shutdown function for detecting label separation of a ribbon. Background Art

[0002] The ribbon is a printing consumable material, mainly used in dot matrix printers. The ribbon is woven into a ribbon base with nylon as the raw material, and is made after being soaked in ink and dyed. The working principle of the ribbon is to use the dot matrix striker in the head of the dot matrix printer or the letter striker in the English typewriter to hit the printing ribbon, thereby producing a printing effect on the printing paper. When processing the ribbon, the ribbon can easily detach from the tension roller of the processing equipment. If the ribbon detaches, but the printing process continues, there may be serious problems with the printed content, such as incomplete printed content, extremely poor print quality, and even printer jams and other faults that may cause unclear printed images, blurred text or distorted colors. Utility Model Content

[0003] The main purpose of the utility model is to provide an automatic alarm and shutdown function for detecting ribbon label detachment, which can effectively solve the problem in the background technology that when the ribbon is processed, the ribbon is easily detached from the tensioning roller of the processing equipment. If the ribbon is detached but the printing process continues, the printed content may have serious problems, such as incomplete printed content, extremely poor print quality, and even printer jams and other malfunctions resulting in unclear printed images, blurred text or distorted colors.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A ribbon label-off detection automatic alarm and shutdown function, comprising a frame, with a plurality of tension rollers rotatably mounted on one side of the frame;

[0006] A support frame is fixedly installed on one side of the frame close to the tensioning roller, a movable frame is arranged on one side of the support frame, and a slot-type photoelectric sensor is installed on one side of the movable frame close to the frame.

[0007] Preferably, a slide groove is provided through the surface of one side of the support frame, a slider is slidably arranged in the slide groove, and one side of the slider is fixedly connected to the movable frame.

[0008] Preferably, a screw rod is rotatably installed between the two sides of the inner wall of the slide groove, the sliding block is slidably arranged on one side of the screw rod body, and one end of the screw rod passes through the support frame and is fixedly installed with a rotating wheel.

[0009] Preferably, the movable frame is fixedly mounted with a baffle, and a limiting groove is provided on one side surface of the baffle.

[0010] Preferably, rubber blocks are fixedly mounted on both sides of the inner walls of the two limiting grooves.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The staff places the ribbon on the tension roller body, and then controls the movement of the ribbon relative to the tension roller, so that the ribbon moves relative to the slot of the slot-type photoelectric sensor, so that the slot-type photoelectric sensor monitors the ribbon in real time. When the ribbon detaches from the tension roller body, the slot-type photoelectric sensor detects that there is no ribbon in the slot, and then issues an alarm and controls the winding device to stop running, thereby stopping the transportation of the ribbon and avoiding quality accidents.

[0018] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 4 As shown, a ribbon label-off detection automatic alarm and shutdown function comprises a frame 1, and a plurality of tension rollers 2 are rotatably mounted on one side of the frame 1;

[0020] A support frame 3 is fixedly installed on one side of the frame 1 close to the tensioning roller 2 , a moving frame 4 is arranged on one side of the support frame 3 , and a slot-shaped photoelectric sensor 5 is installed on one side of the moving frame 4 close to the frame 1 .

[0021] The staff places the ribbon on the roller body of the tensioning roller 2, and then controls the movement of the ribbon to make it move relative to the tensioning roller 2, so that the ribbon moves relative to the slot of the slot-type photoelectric sensor 5, so that the slot-type photoelectric sensor 5 can monitor the ribbon in real time. When the ribbon detaches from the roller body of the tensioning roller 2, the slot-type photoelectric sensor 5 detects that there is no ribbon in the slot and then issues an alarm and controls the winding equipment to stop running, thereby stopping the transportation of the ribbon and avoiding quality accidents.

[0022] In another embodiment of the utility model, a slide groove 6 is formed through the surface of one side of the support frame 3 , a slider 7 is slidably disposed in the slide groove 6 , and one side of the slider 7 is fixedly connected to the moving frame 4 .

[0023] A screw rod 8 is rotatably installed between the two sides of the inner wall of the slide groove 6, and a slider 7 is slidably arranged on one side of the rod body of the screw rod 8. One end of the screw rod 8 passes through the support frame 3 and is fixedly installed with a rotating wheel 9.

[0024] The staff rotates the rotating wheel 9 to drive the screw rod 8 to rotate. The rotating screw rod 8 drives the slider 7 and the movable frame 4 to move along the slide groove 6 by screwing in the thread, so that the staff can adjust according to the width of the ribbon.

[0025] In another embodiment of the utility model, a baffle 10 is fixedly installed on the movable frame 4 , and a limiting groove 11 is provided on one side surface of the baffle 10 .

[0026] By providing the limiting groove 11 , when the ink ribbon breaks, the limiting groove 11 can shield the broken ink ribbon from hitting the slot-type photoelectric sensor 5 , thereby preventing the slot-type photoelectric sensor 5 from being damaged.

[0027] In another embodiment of the present invention, rubber blocks 12 are fixedly mounted on both sides of the inner walls of the two limiting grooves 11 .

[0028] By providing the rubber block 12 , the impact force generated when the ribbon breaks is further reduced, and damage to the slot-type photoelectric sensor 5 is further avoided.

[0029] The working principle of the automatic alarm and shutdown function of the ribbon label removal detection:

[0030] When in use, the staff places the ribbon on the roller body of the tensioning roller 2, and then controls the movement of the ribbon to make it move relative to the tensioning roller 2, so that the ribbon moves relative to the slot of the slot-type photoelectric sensor 5, so that the slot-type photoelectric sensor 5 can monitor the ribbon in real time. When the ribbon detaches from the roller body of the tensioning roller 2, the slot-type photoelectric sensor 5 detects that there is no ribbon in the slot and then issues an alarm and controls the winding equipment to stop running, thereby stopping the transportation of the ribbon and avoiding quality accidents.

[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
