Description

Technical Field

[0001] The utility model relates to the technical field of ribbon detection, in particular to a ribbon break sensing device. Background Art

[0002] When packaging food, we need ribbons to print product information or production date, and ribbons are a kind of printing consumables that we are familiar with. From the earliest mechanical impact-type English printers to the later computer dot matrix printers, ribbons are used. The composition of the ribbon is very simple. It is made of a nylon base woven with ink and dyed. The working principle of the ribbon is to use the dot matrix striker in the dot matrix printer head or the letter striker in the English typewriter to hit the printing ribbon to produce a printing effect on the printing paper.

[0003] When printing a ribbon on the outer packaging of food, the ribbon is attached to the outer packaging by sticking or hot-melting the ribbon to the outer packaging. Since the ribbon needs to be attached to the base tape during transportation, the ribbon is transported by conveying the base tape, and after the base tape contacts the outer packaging, the ribbon is separated from the base tape and attached to the outer packaging. Whenever the attachment fails, the ribbon continues to be transported with the base tape. At this time, it is difficult to understand whether the ribbon is broken and attached to the outer packaging from the transportation condition of the base tape. In view of the above characteristics, a ribbon break sensing device is proposed to detect the adhesion condition of the ribbon. Utility Model Content

[0004] The utility model aims to provide a ribbon break sensing device, which has the advantage of detecting whether the ribbon is broken from the base band, and solves the problem that it is difficult to immediately find out after the ribbon is broken.

[0005] To achieve the above object, the utility model provides the following technical solutions: a ribbon break sensing device, comprising a detection frame, wherein a cavity is provided inside the detection frame, and a sensor body is embedded and installed in the cavity bottom through a groove, and further comprising a laser emitter and an alarm device body;

[0006] The laser transmitter is arranged in the cavity above the sensor body; the alarm device body is arranged on the front side of the detection frame.

[0007] When using a ribbon break sensing device in the technical solution, the baseband body for attaching the ribbon passes between the two feed wheels, and the laser transmitter is started and irradiates the baseband body. When the ribbon is not attached to the baseband body, the laser passes through the baseband body and illuminates the sensor body. At this time, the green light on the alarm device body lights up. When the ribbon is not broken and falls off from the baseband body, it is difficult for the laser to pass through the ribbon and the baseband body, which makes it difficult for the sensor body to receive the light source, so that the alarm device body emits an alarm sound and the red light lights up.

[0008] Preferably, mounting frames are fixedly mounted on both sides of the detection frame, and feed wheels are rotatably mounted on ends of the two mounting frames facing away from the detection frame.

[0009] Preferably, there are two feeding wheels, and the base belt body passes through the two feeding wheels.

[0010] Preferably, the baseband body passes through a cavity of the detection frame, the baseband body in the cavity is located on a side opposite to the sensor body and the laser emitter, and the baseband body is designed with a transparent film material.

[0011] Preferably, the sensor body is electrically connected to the alarm device body via a connecting wire.

[0012] Preferably, a battery compartment is fixedly mounted on the top of the laser transmitter, and the battery compartment is embedded in the top of the detection frame.

[0013] Preferably, an alarm speaker is provided on one side of the front of the alarm device body, and a red light and a green light are provided on the other side of the front of the alarm device body.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model sets a detection frame and passes the baseband body through the detection frame. At this time, the laser emitter can emit laser and make the laser pass through the baseband body to irradiate the sensor body. When the color ribbon on the baseband body fails to break and falls off, the laser emitted by the laser emitter is difficult to pass through the color ribbon and the baseband body. At this time, it is difficult for the sensor body to sense the light source, thereby achieving the effect of detecting whether the color ribbon is broken from the baseband.

[0019] The following will be combined with the drawings in 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 in 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.

[0020] Example

[0021] like Figure 1 and Figure 2 As shown, the utility model provides an embodiment: a ribbon break sensing device, including a detection frame 2, a cavity is provided inside the detection frame 2, and a sensor body 6 is embedded and installed in the cavity bottom. It also includes a laser emitter 4 and an alarm device body 8;

[0022] Specifically, the laser emitter 4 is arranged in the cavity above the sensor body 6; the alarm device body 8 is arranged on the front of the detection frame 2. By setting the detection frame 2 and passing the baseband body 7 through the detection frame 2, the laser emitter 4 can emit laser light and make the laser light pass through the baseband body 7 and irradiate the sensor body 6. When the ribbon on the baseband body 7 fails to break and falls off, the laser light emitted by the laser emitter 4 is difficult to pass through the ribbon and the baseband body 7. At this time, it is difficult for the sensor body 6 to sense the light source, thereby achieving the effect of detecting whether the ribbon is broken from the baseband.

[0023] Furthermore, mounting frames 1 are fixedly installed on both sides of the detection frame 2, and feed wheels 5 are rotatably installed on the ends of the two mounting frames 1 facing away from the detection frame 2. There are two feed wheels 5, and a baseband body 7 passes through the two feed wheels 5. The baseband body 7 passes through the cavity of the detection frame 2, and the baseband body 7 in the cavity is located on the side opposite to the sensor body 6 and the laser emitter 4, and the baseband body 7 is designed with a transparent film material.

[0024] Furthermore, the sensor body 6 is electrically connected to the alarm device body 8 via a connecting wire.

[0025] Furthermore, a battery compartment 3 is fixedly installed on the top of the laser emitter 4 , and the battery compartment 3 is embedded and installed on the top of the detection frame 2 .

[0026] Furthermore, an alarm speaker is provided on one side of the front of the alarm device body 8, and a red light and a green light are provided on the other side of the front of the alarm device body 8.

[0027] When the utility model is used, the baseband body 7 for attaching the ribbon passes between the two feed wheels 5, and the laser emitter 4 is started and irradiates the baseband body 7. When the ribbon is not attached to the baseband body 7, the laser passes through the baseband body 7 and irradiates the sensor body 6. At this time, the green light on the alarm device body 8 lights up. When the ribbon is not broken and falls off from the baseband body 7, it is difficult for the laser to pass through the ribbon and the baseband body 7, which makes it difficult for the sensor body 6 to receive the light source, so that the alarm device body 8 emits an alarm sound and the red light lights up.
