[0029] 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.

[0030] See also Figure 1-6 The utility model provides a technical solution: a scraper device with an automatic cleaning mechanism, such as Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, a scraper structure 1 is included, and the scraper structure 1 includes a basic scraper scraping body 101, and a mounting frame 102 is fixed to the bottom of the scraper scraping body 101, and a sliding groove 103 is opened on one side of the mounting frame 102 for facilitating the sliding adjustment of a slider 104.

[0031] Furthermore, in the above scheme, an electromagnet 105 is fixed inside the mounting frame 102, and the electromagnet 105 is fixed to the scraper 106 by electromagnetic adsorption, wherein the electromagnet 105 is controlled and adjusted by the printer controller, so that the operator can press the printer to drive and control the electromagnet 105 to open and close the operation.

[0032] like Figure 5 and Figure 6 As shown, an automatic cleaning structure 2 is fixed on one side of the scraper structure 1, and the automatic cleaning structure 2 includes a linear motor group 201 fixed on one side of the mounting frame 102, and the linear motor group 201 is rotatably connected to one end of a connecting rod 202 through components, and the other end of the connecting rod 202 is fixedly connected to the outer side of a recessed block 203, wherein the above-mentioned components constitute a reciprocating adjustment structure, and when the above-mentioned components constitute a reciprocating adjustment structure, the recessed block 203 is effectively driven to perform reciprocating drive adjustment, thereby reciprocatingly wiping and absorbing oil on both sides of the scraper 106.

[0033] Furthermore, in the above scheme, a through-hole rod 204 is fixed at one end of the connecting rod 202, and the through-hole rod 204 is rotatably connected to the adjusting cylinder 205 via a movable connecting piece, and the adjusting cylinder 205 is fixedly connected to the slider 104 via a movable connecting piece, wherein the above-mentioned components constitute a rotation adjustment structure, and the rotation adjustment structure constituted by the above-mentioned components can effectively change the rotation angle and rotation position of the concave block 203, so as to avoid the concave block 203 from interfering with the operation of the scraper 106 during operation.

[0034] In the above scheme, a Velcro group 206 is fixed to the inner side of the concave block 203, and two Velcro groups 206 are provided. The Velcro groups 206 are respectively fixedly connected to the concave block 203 and the oil-absorbing sponge 207. When the above-mentioned components are provided with two groups of four pieces, this not only reflects the adhesion connectivity of the above-mentioned components, but also reflects the quick pulling and disassembly between the above-mentioned components. When the above-mentioned components are provided with two groups of four pieces, the practicality of the installation of the above-mentioned components is also reflected. The concave block 203 is adhered to the oil-absorbing sponge 207 through the Velcro group 206, and the oil-absorbing sponge 207 is provided with one group, and the oil-absorbing sponge 207 is provided with two groups. 07 Regarding the central symmetrical installation of the recessed block 203, when the above-mentioned components are provided in a group of two pieces, this not only reflects the wrapping, wiping and oil absorption of the above-mentioned components on both sides of the scraper 106, but also reflects the quick replacement, disassembly and installation of the above-mentioned components. Among them, the oil-absorbing sponge 207 is like wiping the residual ink with a clean rag at the beginning. After long-term use, the oil-absorbing sponge 207 will be like a dirty rag and will not be able to effectively absorb the residual ink of the scraper 106, and may even contaminate the scraper 106, producing a counterproductive effect. Therefore, the oil-absorbing sponge 207 is replaced after long-term use.

[0035] In the above scheme, when ink adheres to the surface of the scraper 106, the controller of the printer device automatically controls the operation of the adjusting cylinder 205 and the linear motor group 201. When the adjusting cylinder 205 is in operation, the recessed block 203 is adjusted to a suitable position through the through-hole rod 204 and the connecting rod 202. At this time, the linear motor group 201 drives the recessed block 203 to wrap the bottom of the scraper 106 and reciprocately wipe and absorb the oil through the oil-absorbing sponge 207. When the scraper 106 has been used for a long time, the operator controls the controller of the printer device to control the operation of the electromagnet 105 to separate the electromagnet 105 from the scraper 106, so as to facilitate the quick replacement of the scraper 106.
