Description

Technical Field

[0001] The utility model relates to the technical field of offset printing machines, in particular to an automatic ink stirring mechanism for offset printing machines. Background Art

[0002] An offset printing press is a type of lithographic printing press. During printing, the printed image is first printed from the printing plate onto a rubber cylinder, and then transferred to the paper by the rubber cylinder and the ink roller. The ink supply device provides pigment to the ink roller.

[0003] The existing automatic ink stirring mechanism of offset printing presses does not have a comprehensive stirring range, and ink materials with high concentrations are prone to condensation.

[0004] The reason for this problem is that the offset printing machine prints on paper by the rotation between the cylinder and the ink roller. The ink roller is provided with ink pigment by the ink supply device. The ink supply device is provided with an ink cartridge inside. The ink cartridge is used to store and provide pigment. Some pigments are highly viscous and have a high concentration. In order to prevent the pigment from condensing inside the ink cartridge, a film stirring device is provided inside the ink cartridge. In order to facilitate the installation of the ink cartridge inside the ink supply device, the shape of the ink cartridge is set to be a rectangular parallelepiped. The film stirring device rotates to stir the pigment inside the ink cartridge. If the pigment concentration is high, the fluidity of the pigment under stirring will be poor, so that the film device can only stir the pigment in the middle position of the ink cartridge, while the pigment at the front and rear ends of the ink cartridge is in a relatively static state, which will affect the automatic ink stirring effect of the film stirring device, so that the film device cannot automatically stir the pigment with a high concentration, thereby reducing the efficiency of the film device. Therefore, we propose an automatic ink stirring mechanism for the offset printing machine. Utility Model Content

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] The embodiment of the utility model discloses a binding device for file arrangement.

[0028] According to the attached Figure 1-5 As shown, it includes an offset printing machine body 1, an ink cartridge 102 is installed above the offset printing machine body 1, an ink stirring mechanism is arranged inside the ink cartridge 102, and the ink stirring mechanism includes an ink stirring plate 2, which is rotatably arranged inside the ink cartridge 102, and the ink stirring plate 2 is used to stir the ink material inside the ink cartridge 102, a control block 201 is arranged below the ink stirring plate 2, and the control block 201 rotates with the ink stirring plate 2, a stop block 211 is movably arranged inside the ink stirring plate 2, and the stop block 211 is abutted against the outside of the control block 201, and the protruding positions on both sides of the control block 201 push the stop block 211 to move, and an auxiliary plate 203 is arranged on the side of the stop block 211, and the auxiliary plate 203 is used to stir the ink material at both sides of the ink cartridge 102.

[0029] An ink supply device 101 is installed above the offset printing machine body 1, and the ink cartridge 102 is installed inside the ink supply device 101. An installation box 210 is provided above the ink cartridge 102, and a motor 205 is installed inside the installation box 210. The outer surface of the output end of the installation box 210 is fixedly connected to a connecting rod 204, the ink stirring plate 2 is fixedly connected to the outside of the connecting rod 204, and the control block 201 is fixedly connected to the bottom end of the connecting rod 204.

[0030] The side of the block 211 is fixedly connected to the telescopic sleeve 202, the other end of the telescopic sleeve 202 is fixedly connected to the inside of the ink cartridge 102, the auxiliary plate 203 is sleeved on the outside of the telescopic sleeve 202, the inside of the ink cartridge 102 is fixedly connected to the support rod 207, the lower surface of the telescopic sleeve 202 is fixedly connected to the support frame 206, the support frame 206 is movably sleeved on the outside of the support rod 207, the inside of the telescopic sleeve 202 is fixedly connected to the telescopic rod 209, the outside of the telescopic rod 209 is movably sleeved with a spring 208, the other end of the telescopic rod 209 is fixedly connected to the inside of the ink cartridge 102, and the other end of the spring 208 is fixedly connected to the inside of the ink cartridge 102.

[0031] The printing material is placed between the two sets of rollers inside the offset printing machine body 1, and then the printing material is driven into the offset printing machine body 1 by the rotation of the rollers. At the same time, the roller ink roller prints the printing material during the rotation process.

[0032] The motor 205 is turned on by the control device, so that the motor 205 drives the connecting rod 204 to rotate, and the connecting rod 204 drives the ink stirring plate 2 to rotate during the rotation. At this time, the ink stirring plate 2 will stir the middle position inside the ink cartridge 102 during the rotation. The connecting rod 204 will cause the control block 201 to rotate during the rotation. When the protruding positions on both sides of the control block 201 contact the retaining block 211, the retaining block 211 will be pushed to move to the positions on both sides of the ink cartridge 102. The outside of the control block 201 is all arc-shaped, and the side position of the retaining block 211 is also an arc surface. When the outside of the control block 201 contacts the arc surface of the retaining block 211, it will squeeze the retaining block 211 to move. When the retaining block 211 moves to the positions on both sides of the ink cartridge 102, it will drive the telescopic sleeve 202 to shrink. At this time, the inside of the telescopic sleeve 202 will contact the ink cartridge 102 The inner wall of the control block 201 squeezes the spring 208, causing the spring 208 to contract. At this time, the telescopic rod 209 will also contract until the protruding positions on both sides of the control block 201 leave the side of the block 211, and the block 211 will lose its driving force, causing the spring 208 to lose its squeezing force and generate tension. Under the action of the tension of the spring 208, the block 211 is driven back to its original position, thereby repeatedly driving the block 211 to move back and forth, thereby causing the auxiliary plate 203 to move back and forth. While the auxiliary plate 203 moves back and forth, it stirs the pigment at both ends of the ink cartridge 102, thereby cooperating with the ink stirring plate 2 to fully stir the material inside the ink cartridge 102, and the auxiliary plate 203 can cooperate to complete the stirring of the pigment at both ends of the ink cartridge 102 when the ink stirring plate 2 rotates, thereby increasing the stability and comprehensiveness of the automatic stirring inside the ink cartridge 102.

[0033] By setting a connecting rod 204 to drive the ink stirring plate 2 and the control block 201 to rotate, the control block 201 drives the resistance block 211 to move, so that the auxiliary plate 203 can cooperate to complete the stirring of the pigment at both ends of the ink cartridge 102 when the ink stirring plate 2 rotates, thereby increasing the stability and comprehensiveness of the automatic stirring inside the ink cartridge 102.

[0034] The telescopic sleeve 202 is composed of two groups of square tubes. The two groups of square tubes are of different sizes, with the larger tube being connected to the smaller tube. Therefore, when the telescopic sleeve 202 is contracted, the larger tube will be connected to the smaller tube, thereby completing the extension and contraction of the telescopic sleeve 202. The auxiliary plate 203 is fixed to the outside of the larger tube of the telescopic sleeve 202, and the support frame 206 supports the movement of the front end position of the telescopic sleeve 202.

[0035] In summary, compared with the existing technology, it has the following beneficial effects:

[0036] The motor 205 is turned on by the control device, so that the motor 205 drives the connecting rod 204 and the control block 201 to rotate. The protruding positions on both sides of the control block 201 will push the block 211 to move. At this time, the inside of the telescopic sleeve 202 will squeeze the spring 208 with the inner wall of the ink cartridge 102 until the protruding positions on both sides of the control block 201 leave the side of the block 211. The block 211 will lose its driving force and drive the block 211 back to its original position under the action of the tension of the spring 208, thereby repeatedly driving the block 211 to move back and forth, thereby causing the auxiliary plate 203 to move back and forth. While the auxiliary plate 203 moves back and forth, it stirs the paint at both ends of the ink cartridge 102. By setting the connecting rod 204 to drive the ink stirring plate 2 and the control block 201 to rotate, the control block 201 drives the block 211 to move more, so that the auxiliary plate 203 can cooperate to complete the stirring of the paint at both ends of the ink cartridge 102 when the ink stirring plate 2 rotates, thereby increasing the stability and comprehensiveness of the automatic stirring inside the ink cartridge 102.
