Description

Technical Field

[0001] This application belongs to the field of spraying rollers, and particularly relates to a printing roller spraying machine. Background Technology

[0002] Gravure printing involves coating the entire surface of a printing plate with ink, then using a special doctor blade to remove the ink from the non-image areas, leaving only ink in the cells of the image areas. Under pressure, this ink is then transferred to the substrate to produce the printed product. The image areas of the printing plate are recessed, with the degree of recess varying depending on the image's depth, while the non-image areas are raised and lie on the same plane.

[0003] The existing publication number CN211918020U discloses a substitute for a spray-coated gravure printing roller, including a device body. The device body has a left-right supporting and fixing shaft in the middle, and a left-right limiting rotating cylinder is fixedly installed on the outside of the supporting and fixing shaft through bearings at both ends. A left-right gravure printing roller is fitted on the outside of the limiting rotating cylinder, and a transmission gear disk is fixedly installed on the right end of the limiting rotating cylinder by bolts. A limiting annular plate is fixedly installed on the left end of the limiting rotating cylinder by bolts.

[0004] Although the aforementioned printing rollers can be removed after damage, they cannot be adjusted and installed according to different sizes of printing rollers, resulting in poor applicability. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a roller coating machine that can be adjusted and installed according to rollers of different sizes, thus having good applicability.

[0006] This application provides a roller coating machine, including a machine body, a mounting shaft, and further comprising:

[0007] Inner roller body, which is mounted on a mounting shaft;

[0008] An outer printing roller, which is mounted on an inner roller body;

[0009] A locking assembly, which is mounted on the inner roller body;

[0010] The inner roller body includes a left mounting roller, a right mounting roller, and an adjusting roller. Limiting blocks are provided on the left mounting roller and the adjusting roller. The limiting blocks have a cross-shaped cross section. Limiting holes are provided on the left side of the adjusting roller and the right mounting roller. The limiting block on the left mounting roller is inserted into the limiting hole on the left side of the adjusting roller, and the limiting block on the adjusting roller is inserted into the limiting hole on the right mounting roller.

[0011] When the size of the printing roller needs to be adjusted, the mounting shaft is removed from the equipment body, and then the outer printing roller is removed. The inner roller body is then split into a left mounting roller, a right mounting roller, and an adjusting roller. The cross-shaped limiting blocks that are integrally connected to the left mounting roller and the adjusting roller are pulled out from the limiting holes on the left and right mounting rollers, respectively. Then, the number of adjusting rollers spliced ​​in the left and right mounting rollers is increased or decreased according to the size that the user needs to adjust. The inner roller body can be adjusted and installed according to different sizes of outer printing rollers, and has good applicability.

[0012] Furthermore, the locking component includes:

[0013] A locking hole is provided on the limiting block;

[0014] A drive groove is provided on the adjusting roller and the right mounting roller;

[0015] A compression spring, which is mounted on a drive slot;

[0016] A top plate, which is mounted on one end of a compression spring;

[0017] A tie rod, which is mounted on the top plate;

[0018] A locking block, which is mounted on the top plate.

[0019] During the splicing of the left mounting roller, adjusting roller, and right mounting roller, the locking block is pushed into the locking hole in the limiting block by the compression spring to fix its position. Several pairs of locking blocks are provided to cooperate with the locking holes. The cooperation between the locking blocks and the locking holes can make the splicing between the left mounting roller, adjusting roller, and right mounting roller more secure and the position more stable. When it is necessary to disassemble the inner roller body, the outer roller is removed first, and then the pull rod is pulled outward to compress the compression spring. The locking block is lifted into the drive groove, and the inner roller body can be disassembled at this time.

[0020] Furthermore, a first mounting groove is provided on the side of the inner roller body, and a second mounting groove is provided on the outer roller. A limiting plate is inserted into the first mounting groove and the second mounting groove.

[0021] The outer printing roller is inserted into the inner roller body. When the outer printing roller is inserted into the inner roller body, the user inserts the limiting plate into the groove formed by the splicing of the first mounting groove and the second mounting groove. The limiting plate can be used to connect and fix the outer printing roller and the inner roller body after the subsequent position is fixed, so that the outer printing roller and the inner roller body are less likely to loosen and shift position after assembly, thus improving the stability of the printing roller operation.

[0022] Furthermore, the limiting plate is provided with a plurality of locking plates, and the first mounting groove and the second mounting groove are both provided with grooves that fit and splice with the locking plates on the limiting plate.

[0023] The limiting plate is provided with a number of locking plates. The first and second mounting slots are provided with slots that fit and splice with the locking plates on the limiting plate. The locking plates and the slots on the limiting plate that fit and splice with the locking plates can be installed together to limit the position of the outer roller and the inner roller, so as to prevent the outer roller from being unable to rotate when the inner roller rotates.

[0024] Furthermore, each of the locking plates is provided with a through hole, and the first mounting groove and the second mounting groove are each provided with a plurality of threaded holes. The bolt passes through the through hole on the locking plate and is installed in the threaded holes on the first mounting groove and the second mounting groove respectively.

[0025] Each of the locking plates has a through hole. When it is necessary to connect and fix the inner roller body and the outer plate roller and the limiting plate, several bolts are used to pass through the through holes on the locking plate and are respectively installed in the threaded holes on the first mounting groove and the second mounting groove. This makes the position of the inner roller body and the outer plate roller more stable and safe, and at the same time makes it easier for users to disassemble and install the inner roller body and the outer plate roller.

[0026] Furthermore, a handle is installed on the pull rod.

[0027] The lever is equipped with a handle, which makes it easier for the user to pull out and lift the lever, making the operation more convenient and efficient.

[0028] The beneficial effects of this application are:

[0029] 1. The inner roller body can be adjusted and installed according to outer rollers of different sizes, making it highly adaptable;

[0030] 2. The cooperation between the locking block and the locking hole makes the splicing between the left mounting roller, the adjusting roller, and the right mounting roller more secure and the position more stable;

[0031] 3. The grooves on the locking plate and the limiting plate that fit and splice with the locking plate can limit the position of the outer roller and the inner roller, so as to prevent the outer roller from being unable to rotate when the inner roller rotates. Attached Figure Description
