[0052] In the description of this application, if there is a description of first or second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0053] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0054] Reference Figure 1 and Figure 8The present application provides a tape measure inkjet printer, comprising a conveying unit, a feeding unit 100, a first tensioning unit 300, a first printing unit and a receiving unit 1000, wherein the conveying unit comprises a plurality of conveying rollers, which are arranged along a preset conveying path and are used to convey the tape material; the feeding unit 100 is arranged at the head end of the conveying path, and is used to provide blank tape material to the conveying unit; the first tensioning unit 300 is arranged on the conveying path, and is used to keep the tension of the tape material stable when it moves; the first printing unit is arranged on the conveying path, and is located at the rear side of the first tensioning unit 300 relative to the conveying path, and the first printing unit comprises a nozzle 413 module 410, an inkjet wheel module 420 and an ink recovery module 430; the nozzle 413 module 410 It is arranged above the transmission path and above the inkjet disc module 420; the inkjet disc module 420 includes a driving shaft 421, a main inkjet disc 422, an inner auxiliary inkjet disc 423 and an outer auxiliary inkjet disc 424, the inner auxiliary inkjet disc 423 is sleeved on the inner side of the main inkjet disc 422, the outer auxiliary inkjet disc 424 can be movably sleeved on the main inkjet disc 422, and the driving end of the driving shaft 421 is connected to the center position of the main inkjet disc 422; the ink recovery module 430 includes an ink scraping assembly and an ink recovery component 450, the ink scraping assembly is arranged below the inkjet disc module 420 and is against the inkjet disc module 420, and the ink recovery component 450 is arranged below the ink scraping assembly; the material receiving unit 1000 is arranged at the end of the transmission path, and is used to roll up the tape material that has completed inkjetting from the transmission unit. The feeding unit 100 provides the tape material for the transmission unit, and the first tensioning unit 300 ensures that the tension of the tape material is stable, thereby improving the accuracy of printing. At the same time, in order to realize the printing of tapes of different widths, the outer auxiliary inkjet disc 424 can be moved in a direction away from the main inkjet disc 422, so that the edge of the tape is always on the inner auxiliary inkjet disc 423 and the outer auxiliary inkjet disc 424, so as to ensure that the excess ink from printing can accurately flow to the ink recovery module 430, which is convenient for ink recovery. In the first printing unit, the size of the main inkjet disc 422 is adjusted by adjusting the movable outer auxiliary inkjet disc 424, so as to adapt to the printing of tape materials of different specifications and reduce production costs. , which improves the flexibility of production. For example, when it is necessary to print on a wider tape, the outer auxiliary inkjet disc 424 is stretched outward for a distance so that the two sides of the tape are respectively against the inner auxiliary inkjet disc 423 and the outer auxiliary inkjet disc 424, so that the edge of the tape measure is always on the inner auxiliary inkjet disc 423 and the outer auxiliary inkjet disc 424; at the same time, the excess ink at the inner auxiliary inkjet disc 423 and the outer auxiliary inkjet disc 424 is scraped off by the ink scraping component under the inkjet wheel module 420, and flows to the ink recovery part 450 for recovery, effectively ensuring the cleanliness of the tape material during the continuous printing process, and finally the printed tape material is rolled up by the material collection unit 1000.

[0055] Reference Figure 2 It can be understood that the feeding unit 100 includes a feeding shaft assembly 110, and the feeding shaft assembly 110 includes a material shortage sensor 111, a feeding shaft body 112, and a material baffle mounting block 113, an inner tape material baffle 114, an outer tape material baffle 115 and a material limit stopper 116 which are sequentially sleeved on the feeding shaft body 112, a gap for placing the tape material is left between the inner tape material baffle 114 and the outer tape material baffle 115, the material baffle mounting block 113 is provided with a positioning column 113a which passes through the inner tape material baffle 114, the outer tape material baffle 115 and the material limit stopper 116 in sequence, and the inner tape material baffle 114 is provided with a first sensing slot 114a at the position of the material shortage sensor 111. When the material roll diameter is smaller than the roll diameter that can be sensed by the material shortage sensor 111, the material shortage sensor 111 transmits a material shortage signal to limit the machine running speed, thereby improving the intelligence of the tape measure inkjet printer. At the same time, the material limit block 116 limits the outer tape measure material baffle 115, thereby limiting the tape measure material.

[0056] Reference Figure 3 It is understandable that the feeding unit 100 further includes a dust removal assembly 120, which is disposed on the conveying path. The dust removal assembly 120 includes a dust removal bottom plate 121, a dust removal fixing plate 122 and a sponge. The dust removal fixing plate 122 fixes the sponge on the dust removal bottom plate 121, and the sponge can contact the tape material on the conveying path. When the material passes through the dust removal assembly 120, the surface dust is contaminated on the sponge, thereby achieving dust removal of the tape material and improving the cleanliness of the surface of the tape material.

[0057] Continue to refer to Figure 3 It can be understood that the feeding unit 100 further includes a brake assembly 130, which includes a cylinder 131, a brake sensor 132, a cylinder 131 fixing plate and a brake fixing plate 134. The cylinder 131 is arranged on the cylinder 131 fixing plate, and the driving end of the cylinder 131 and the brake fixing plate 134 are arranged on both sides of the conveying path. The brake fixing plate 134 is parallel to the driving end surface of the cylinder 131. The brake sensor 132 is arranged on the cylinder 131 fixing plate and at the front end of the cylinder 131 relative to the conveying path. When the brake sensor 132 cannot sense the material, the controller controls the driving end of the cylinder 131 to extend, and the driving end of the cylinder 131 is pushed against the brake fixing plate 134, so as to clamp the material to prevent the material from running when the material is broken.

[0058] Continue to refer to Figure 4It can be understood that the tape measure inkjet printer provided by the present application also includes a protection unit, which is arranged on the transmission path and is located between the feeding unit 100 and the first tensioning unit 300; the protection unit includes a dust suction component 210, and the dust suction component 210 includes a feed square tube 211 and an air suction pipe 212. The transmission path passes through the feed square tube 211, and the feed square tube 211 is provided with an air suction hole 211a. One end of the air suction pipe 212 is connected to the air suction hole 211a, and the other end of the air suction pipe 212 is used to connect to the centrifuge. When the centrifuge is started, a negative pressure is formed at the air suction hole 211a to clean the dust on the surface of the tape measure, so as to further improve the cleanliness of the surface of the tape measure material, so as to facilitate better printing of ink on the surface of the tape measure material.

[0059] Reference Figure 5 It can be understood that the protection unit also includes a joint protection component 220, which includes a joint detection rod 221 and a joint protection sensor 222. The joint detection rod 221 is provided with a thickness sensing sheet 223 at one end close to the transmission path, and the lower end of the thickness sensing sheet 223 is against the tape material. The other end of the joint detection rod 221 is provided with a sensor plate 224. The joint protection sensor 222 is used to sense the position of the sensor plate 224 to determine the thickness of the tape material passing through the thickness sensing sheet 223. When the material thickness is normal, the sensor plate 224 is set close to the joint protection sensor 222. When the material thickness is thicker, the thickness sensing sheet 223 is touched and lifted due to the change in material thickness, and the sensor plate 224 is no longer close to the joint protection sensor 222. The joint protection sensor 222 transmits the joint signal to the controller. After calculating the distance, the controller controls the printing module to lift up when the joint is approaching to prevent the joint from scratching the nozzle 413, and the printing software controls the nozzle 413 to stop printing. Since the product with the joint is scrapped, when the joint passes the nozzle 413, the controller controls the printing module to descend, and the printing software restarts printing the tape measure. The whole process does not require shutdown, which greatly reduces material waste.

[0060] Reference Figure 6It can be understood that the first tensioning unit 300 includes a tensioning mounting back plate 310, a mounting base plate 320, a mounting top plate 330, a first positioning rod 340, a second positioning rod 350, a tensioning guide wheel 360, a connecting rod 370, a counterweight block 380 and a connecting body 390. The mounting base plate 320 and the mounting top plate 330 are respectively arranged parallel to each other at the bottom and top ends of the tensioning mounting back plate 310. The first positioning rod 340 and the second positioning rod 350 are respectively parallel to each other, and the two ends are respectively connected to the mounting base plate 320 and the mounting top plate 330. The connecting body 390 is sleeved on the first positioning rod 340 and the second positioning rod 350. The side of the connecting body 390 close to the transmission path is connected to the tensioning guide wheel 360, and the side of the connecting body 390 away from the transmission path is connected to the counterweight block 380 through the connecting rod 370. The tensioning mounting back plate 310 is provided with an elliptical opening 311, and the connecting rod 370 passes through the elliptical opening 311. During actual use, the measuring tape material passes under the tensioning guide wheel 360, and the counterweight block 380 maintains a balance with the material tension. When the material tension changes, the tensioning assembly moves up and down to keep the counterweight block 380 and the material tension in relative balance, thereby ensuring the stability of the tension during printing and effectively guaranteeing the printing accuracy.

[0061] Reference Figure 7The nozzle 413 module 410 includes a nozzle frame 411, a nozzle base plate 412, a nozzle 413, a board 414, a secondary ink cartridge 415 and a circulating ink cartridge 416.
