Ink scraper

[0015] Please refer to image 3 with Figure 4 The ink squeegee 4 includes a squeegee holder 20 and a squeegee head 10, and the squeegee holder 20 is provided with a groove 22 to hold the squeegee head 10.

[0016] The scraper holder 20 includes a push-and-hold mechanism 220, a housing 230, and a force control mechanism 240, wherein the housing 230 is a hollow cylinder. The housing 230 includes a cylindrical wall 232, a neck 234, and an inner cavity 238. The cylindrical wall 232 is provided with a scale 2320, and the neck 234 is longitudinally provided with a hole 2340. The push-grip mechanism 220 includes a grip 222 and an actuating rod 224, and the force control mechanism 240 includes a spring and a finger plate 244.

[0017] One end of the actuating rod 224 fixes the handle 222, and the other end of the actuating rod 224 penetrates the cavity 238 from the hole 2340. The spring 242 is longitudinally sleeved on one end of the actuating rod 224 located in the inner cavity 238, and one end of the spring 242 is fixed to the neck 234, and the other end is fixed to the finger plate 244. The finger plate 244 is fixed at one end of the actuating rod 224 penetrating into the inner cavity 238 and is arranged corresponding to the scale 2320.

[0018] The neck 234 is tightly connected to the actuating rod 224, which can prevent the actuating rod 224 from shaking left and right when the actuating rod 224 is scraped. The finger plate 244 can indicate the scale of the spring 242 when the force is applied, and the groove 22 can hold the scraper. For the head 10, when the scraper head 10 is worn out, only the scraper head 10 can be replaced instead of the entire ink scraper 4, so that the cost can be reduced.

[0019] The scraper head 10 is mainly made of rubber material, and the housing 20 can be made of low-priced transparent hard plastic, such as PVC resin, that is, polyvinyl chloride.

[0020] Since the squeegee holder 20 of the ink squeegee 4 of the present invention is equipped with a force control mechanism 240 based on the principle of Hook's Law, the spring 242 of the force control mechanism 240 can be controlled to a certain amount of deformation when it is scraped, so that it can be accurately Control the printing force, and evenly draw the ink to one side, so that the thickness of the ink on the printed matter is uniform, and the printing quality is improved.

[0021] Please refer to Figure 5 , Is a schematic diagram of the second embodiment of the ink squeegee 6 of the present invention. The ink scraper 6 includes a scraper holder 40 and a scraper head 30. The scraper holder 40 is provided with a groove 42 for holding the scraper head 30.

[0022] The scraper holder 40 includes a push-and-hold mechanism 420, a housing 430, and a force control mechanism 440, wherein the housing 430 is a hollow cylinder. The housing 430 includes a cylindrical wall 432, a neck 434, and an inner cavity 438. The neck 434 is longitudinally provided with a hole 4340. The push-and-grip mechanism 420 includes a handle 422 and an actuating rod 424, and the actuating rod 424 is provided with a scale 4240. The force control mechanism 440 includes a spring 424 and a pointer 444.

[0023] One end of the actuating rod 424 fixes the handle 422, the other end of the spring 442 penetrates the inner cavity 438 from the hole 4340, one end of the spring 442 is connected to the neck 434, and the other end is connected to the end of the actuating rod 424 close to the handle 422 The pointer 444 is located at one end of the spring 442 and is set corresponding to the scale 4240.

[0024] The neck 434 is tightly connected to the actuating rod 424, which can prevent the actuating rod 424 from shaking left and right when the actuating rod 424 is scraped. The pointer 444 can indicate the scale of the spring 442 when the force is applied, and the groove 42 can hold the scraper head. 30. When the squeegee head 30 is worn out, only the squeegee head 30 can be replaced, instead of replacing the entire ink squeegee 6, so that the cost can be reduced.

[0025] Please refer to Figure 6 , Is a schematic diagram of the third embodiment of the ink squeegee 8 of the present invention. The ink scraper 8 includes a scraper holder 60 and a scraper head 50, and the scraper holder 60 is provided with a groove 62 to hold the scraper head 50.

[0026] The scraper holder 60 includes a push-and-hold mechanism 620, a housing 630 and a spring 642, wherein the housing 630 is a hollow cylinder. The housing 630 includes a cylindrical wall 632 and an inner cavity 634. The cylindrical wall 632 is provided with a scale 6320. The push-and-grip mechanism 620 includes a grip 622 and an actuating rod 624.

[0027] One end of the actuating rod 624 fixes the grip 622, and the other end penetrates into the inner cavity 634. The spring 642 is disposed in the inner cavity 634 of the housing 630, and one end is connected to the end of the actuating rod 624 that penetrates the inner cavity 634. , The other end is connected to the unopened end of the housing 630, and is arranged corresponding to the scale 6320.

[0028] The cylindrical wall 632 is tightly connected with the actuating rod 624, which can prevent the actuating rod 624 from shaking left and right when it is scraped. The end of the actuating rod 624 is connected to the spring 642 and can indicate the scale of the spring 642 when a force is applied. The groove 62 can hold the scraper head 50. When the scraper head 50 is worn out, only the scraper head 50 can be replaced, instead of replacing the entire ink scraper 8, so that the cost can be reduced.

[0029] However, the ink squeegee of the present invention is not limited to those described in the first, second, and third embodiments, and the housing may be a hollow body, such as a hollow rectangular body, a hollow pentagonal body, or a hexagonal body. The shell can also be made of high-strength, high-toughness glass, or made of light metal aluminum or other low-priced metals. The wall of the metal shell can be provided with an opening to read the cavity The position of the pointer. There can be two or more springs horizontally or longitudinally. The grip can be rectangular or other shapes.
