Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 2, for the utility model discloses a scraper grinds machine, including work platform 1, iron bar 2 along 1 length direction setting of work platform and perpendicular to 1 top surface of work platform, the vertical two spinal branch vaulting poles 21 that are connected with on the top surface of iron bar 2, install the pressfitting crossbeam 3 that parallels with iron bar 2 on the two spinal branch vaulting poles 21, still be fixed with the support bar 4 that is used for supporting the scraper on work platform 1's the top surface, support bar 4 is parallel to each other with iron bar 2, be provided with cylinder pressing mechanism on work platform 1's the top surface, cylinder pressing mechanism is including being fixed in L type fixed plate 5 on 1 top surface of work platform and installing cylinder 6 on L type fixed plate 5, the drive end of cylinder 6 is connected in pressfitting crossbeam 3 perpendicularly. In this embodiment, six L-shaped fixing plates 5 are arranged in parallel along the length direction of the working platform 1, and each two L-shaped fixing plates 5 are provided with one cylinder 6. 6 equidistant interval distribution of cylinder has 3 for the whole atress of pressfitting crossbeam 3 is more even. The support strip 4 is made of iron and shows rustproof treatment, and the flatness of the ground printing scraper is poor due to the fact that the former aluminum material deforms to different degrees in the eye mask process. After being replaced by iron materials, the supporting strip 4 can not deform in the process of grinding stress.

Referring to fig. 2 and 3, a scraper plate cushion block 7 for supporting the scraper is arranged between the supporting strip 4 and the iron bar 2, and the scraper plate cushion block 7 is located on the top surface of the working platform 1. And in the idle area between the supporting strips 4 and the pressing cross beam 3, the scraper plate cushion blocks 7 are placed to support the scrapers, so that the stability of the scrapers is ensured. For convenient installation dismantlement scraper plate cushion 7, the length direction along scraper plate cushion 7 on the bottom surface of scraper plate cushion 7 is connected with the cross-section and is trapezoidal slider 8, offers on work platform 1's the top surface with slider 8 complex spout 81 that slides, is connected with the fixed subassembly that is used for restricting scraper plate cushion 7 and removes along spout 81 length direction on the scraper plate cushion 7. In this embodiment, the fixing component includes a fixing bolt 9 sequentially penetrating through the scraper plate cushion block 7 and the sliding block 8, and a threaded hole matched with the fixing bolt 9 is formed in the sliding groove 81. When the scraper plate cushion block 7 needs to be detached and replaced, the fixing bolt 9 is unscrewed, and the scraper plate cushion block 7 is pulled outwards along the sliding groove 81, so that the sliding block 8 is separated from the sliding groove 81 gradually, and convenience and rapidness are achieved.

Referring to fig. 2, the bottom surface of the press beam 3 is connected with a first rubber filler strip 31, and the top surface of the iron bar 2 is connected with a second rubber filler strip 22. Rubber filler strips are added on two surfaces of the contact scraper, so that the scraper can be pressed tightly after pressing, and the flatness of the scraper is improved.

The implementation principle of the embodiment is as follows: during the pressfitting, change into the direct pressfitting of cylinder 6 drive pressfitting crossbeam 3 up-and-down motion by original angular motion pressfitting, scraper locating position can be more stable like this, reduces the fluctuation of pressfitting process, and the uniformity can be better after the pressfitting. Therefore, the difference of different positions of the products printed in the later period is very small, and the yield is obviously improved.

And in the idle area between the supporting strips 4 and the pressing cross beam 3, the scraper plate cushion blocks 7 are placed to support the scrapers, so that the stability of the scrapers is ensured.

The first rubber gasket strip 31 and the second rubber gasket strip 22 ensure that the scraper can be completely compressed after being pressed, so that the flatness of the scraper is improved.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
