Description

Technical Field

[0001] The present application relates to the field of printing presses, and in particular to a powder spraying device of a printing press. Background Art

[0002] During the printing process, the printed paper needs to enter the next processing flow before the ink is dry in order to speed up printing efficiency. Since the ink is not dry, the ink on the paper often sticks to the upper paper. Therefore, the paper must be powdered before entering the next processing flow to prevent ink adhesion and improve printing quality.

[0003] In related technologies, a powder spraying device consists of a base and a powder spraying tube. A powder recovery box is located at the top of the base, and a vibration motor is installed inside the base to control the vibration of the powder recovery box. The powder recovery box is equipped with a placement table, which has a slope on top, and a clamping bar on top of the slope. In actual operation, the operator places a sheet of paper on the placement table, then moves the clamping bar to press the paper. Powder is sprayed onto the paper through the powder spraying tube. The vibration motor drives the powder recovery box to vibrate, causing the powder accumulated on the paper to slide down the slope. While the powder is being sprayed onto the paper, the excess powder is collected.

[0004] The above-mentioned related technologies have the following defects: after the paper is placed on the placement table, the operator needs to move the clamping bar to press the paper. When the number of papers that need to be powdered is large, the operator needs to move the clamping bar multiple times, which is labor-intensive, affects the pressure exerted by the clamping bar on the paper, and reduces the efficiency of the paper powdering work.

DETAILED DESCRIPTION

[0030] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a powder spraying device for a printing press, such as Figure 1 As shown, the apparatus includes a powder recycling box 1, which includes a placement table 2 within the box. Paper is placed on the placement table 2. A slope 21 is formed on the top of the placement table 2, with the slopes of the left and right ends of the slope 21 being symmetrical. An operator can place paper on the placement table 2 so that it lies flush with the slope 21, facilitating powder spraying.

[0033] like Figure 2 As shown, the recycling powder box 1 includes a base 11 and a baffle 12. The baffle 12 is arranged in a ring shape and is detachably connected to the base 11. A limit plate 111 is fixedly connected to the base 11. The limit plate 111 has an L-shaped cross-section, and there are four limit plates 111. When the baffle 12 needs to be installed, the operator can move the baffle 12 so that the outer side of the baffle 12 is aligned with the inner side of the limit plate 111. The limit plate 111 can limit the position of the baffle 12 to achieve the installation of the baffle 12. When the baffle 12 is installed, the baffle 12 can block the powder that slides off the paper, causing the powder to accumulate in the recycling powder box 1, reducing powder waste.

[0034] like Figure 3 As shown, a pressure rod 3 is provided on the placement table 2, which slides relative to the vertical direction. An arc-shaped plate 31 is fixedly connected to the pressure rod 3. A rubber plate 32 is provided on the side of the arc-shaped plate 31 away from the pressure rod 3. The rubber plate 32 can be moved to abut against the paper to protect the surface of the paper. A first control member for controlling the sliding of the pressure rod 3 is provided on the placement table 2. The first control member is a first cylinder 22. The first cylinder 22 is installed on the placement table 2, and the piston rod of the first cylinder 22 is fixedly connected to the pressure rod 3. When the paper is placed on the placement table 2, the operator can drive the first cylinder 22, so that the piston rod of the first cylinder 22 drives the movement of the pressure rod 3, thereby realizing the lifting and lowering of the pressure rod 3, facilitating the fixation of the paper on the placement table 2, and thus facilitating the powder spraying of the paper.

[0035] like Figure 3 and 4As shown, the placement table 2 and the base 11 rotate relative to each other, and a support block 13 is fixedly connected to the base 11, and the placement table 2 and the support block 13 are rotatably connected. A second control component for controlling the rotation of the placement table 2 is provided on the base 11, and the second control component is a second cylinder 14. The second cylinder 14 is rotatably connected to the recycling powder box 1, and the piston rod of the second cylinder 14 is rotatably connected to the placement table 2. A collection rack 4 is installed on one side of the recycling powder box 1, and a limit rod 41 is fixedly connected to the collection rack 4. When the paper is powdered, the operator drives the first cylinder 22, so that the first cylinder 22 drives the pressure rod 3 to move upward, releasing the force applied by the pressure rod 3 to the paper, and then drives the second cylinder 14, so that the second cylinder 14 pushes the placement table 2 to rotate. The paper on the placement table 2 can slide down under its own gravity and fall into the collection rack 4 for collection.

[0036] The implementation principle of the powder spraying device of a printing press in the embodiment of the present application is as follows:

[0037] The operator drives the first cylinder 22, causing it to raise the pressure rod 3, then places the paper on the placement table 2. The operator then drives the first cylinder 22 again, causing it to lower the pressure rod 3, compacting the paper on the placement table 2 and facilitating the paper powdering process. After the paper powdering process is complete, the operator drives the first cylinder 22, causing it to raise the pressure rod 3, and then drives the second cylinder 14, causing it to rotate the placement table 2. The paper then slides down under its own weight and falls onto the collection rack 4 for collection. The powder generated by the powdering process can be stored in the powder recovery box 1. When the powder needs to be cleaned, the operator can slide the baffle 12 out to clean the powder on the base 11.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
