Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to an anti-static device for paper printing. Background Art

[0002] As printing speeds increase and quality requirements rise, static electricity generated during paper transportation and printing becomes increasingly prominent. Static electricity can not only cause paper to stick to the printing rollers but also cause uneven ink adhesion, seriously impacting print quality and production efficiency.

[0003] The main principle of the paper printing anti-static equipment commonly used in related technologies is that during the printing process, a moistening material containing water is added and installed on the printing equipment. The paper will move in sequence on the printing equipment and enter the printing roller. Before entering the printing roller, the paper will come into contact with the moistening material, thereby reducing the static electricity of the paper by increasing the humidity on the surface of the paper.

[0004] However, in different weather conditions, the humidity in the air is different, and the original humidity of the paper will also be different. Therefore, it is difficult to change the degree of increase in the humidity of the paper surface. If the paper is too dry, the static electricity phenomenon of the paper will not be eliminated significantly, and if the paper is too wet, it will affect printing and the storage of the paper after printing. Utility Model Content

[0005] In order to facilitate changing the degree of increase in the humidity of the paper surface, prevent the paper from being too wet or too dry, and ensure the anti-static effect of paper printing, the present application provides an anti-static device for paper printing.

[0006] The present application provides a paper printing antistatic device that adopts the following technical solution:

[0007] A paper printing anti-static device includes a mounting frame fixedly mounted on the printing device, the mounting frame being provided with a water storage box and a moistening sponge, a plurality of dripping pipes fixedly mounted on the bottom of the water storage box, the dripping pipes being connected to the interior of the water storage box, all of the dripping pipes being located directly above the moistening sponge, a balancing air pipe being provided on the water storage box to connect the inside and outside of the water storage box, the balancing air pipe being a hose, a clamping assembly being provided on the water storage box, the clamping assembly being used to clamp or loosen the balancing air pipe, a contact roller being further provided on the mounting frame, the contact roller being provided with a rotating part for driving the contact roller to rotate, one side of the peripheral wall of the contact roller being used to contact the moistening sponge, and the other side of the peripheral wall of the contact roller being used to contact the paper on the printing device.

[0008] With this technical solution, atmospheric air enters the water storage box through the balancing air pipe. Water in the water storage box drips onto the wet sponge through the dripping pipe, maintaining the sponge's moistness. A rotating member drives the contact roller to rotate, causing it to contact the wet sponge and pick up moisture. The contact roller then contacts the paper and transfers the moisture to the paper, increasing the surface humidity. Under varying weather conditions, the balancing air pipe can be tightened or loosened by the clamping assembly to adjust the rate at which atmospheric air enters the water storage box through the pipe. This, in turn, adjusts the dripping rate, changes the wetness of the wet sponge, and thus the contact roller. This facilitates controlling the amount of moisture transferred to the paper by the contact roller, facilitating the degree of surface humidity increase, preventing the paper from becoming overly wet or overly dry, and ensuring antistatic properties during printing.

[0009] Preferably, the clamping assembly includes a threaded rod, a fixed clamp block, a movable clamp block, and a bracket. The fixed clamp block and the bracket are fixedly arranged on the water storage box. The movable clamp block is located between the bracket and the fixed clamp block. The balancing air pipe is located between the fixed clamp block and the movable clamp block. The threaded rod is rotatably engaged with the bracket. The threaded rod is threadably engaged with the movable clamp block. The threaded rod is used to drive the movable clamp block closer to or away from the bracket.

[0010] By adopting the above technical solution, when it is necessary to clamp the balancing air pipe, the threaded rod is rotated to move the movable clamp away from the bracket and closer to the fixed clamp, and the balancing air pipe is further clamped between the fixed clamp and the movable clamp, thereby limiting the air from entering the water storage box and reducing the dripping speed; when it is necessary to loosen the balancing air pipe, the threaded rod is rotated in the opposite direction to move the movable clamp closer to the bracket and away from the fixed clamp, thereby increasing the ventilation space of the balancing air pipe, accelerating the speed at which air enters the water storage box and increasing the dripping speed.

[0011] Preferably, a support ring is fixedly provided on the side of the fixed clamp away from the water storage box, and the end of the balance air pipe away from the water storage box passes through the support ring.

[0012] By adopting the above technical solution, the support ring can support the balancing air pipe, so that the position of the balancing air pipe between the support ring and the water storage box is constrained, ensuring that the clamped position of the balancing air pipe is stable and not prone to displacement, thereby ensuring the accuracy of the clamping assembly's clamping or loosening operation on the balancing air pipe.

[0013] Preferably, the mounting frame is provided with a slide groove in the vertical direction, a slide block is slidably arranged in the slide groove, the contact roller is rotatably arranged on the slide block, and a slide assembly is provided on the mounting frame, and the slide assembly is used to drive the slide block to slide.

[0014] By adopting the above technical solution, the paper passes through the contact roller on the printing device in sequence. When the contact roller completes transferring moisture to one paper and before the next paper arrives, the sliding component drives the sliding block to move upward, so that the brush roller contacts the wet sponge and the contact roller is soaked with moisture; then the sliding component drives the sliding block to move downward, so that the contact roller returns to its original position. When the next paper passes by, it can transfer moisture to the paper again, ensuring the uniformity of moisture transfer.

[0015] Preferably, the sliding assembly includes a cam, a return spring, and a first motor. The cam is rotatably arranged on a mounting frame, the circumferential wall of the cam is against the sliding block, the first motor is fixedly connected to the mounting frame, the driving shaft of the first motor is coaxially fixed to the cam, the return spring is arranged in a slide groove, one end of the return spring is against the end wall of the slide groove, and the other end of the return spring is against the sliding block, and the return spring drives the sliding block close to the cam.

[0016] With this technical solution, the first motor starts to rotate the cam. When the cam's protruding portion no longer contacts the sliding block, the return spring's force drives the sliding block upward, causing the contact roller to come into contact with the wet sponge and become wet. When the cam's protruding portion contacts the sliding block, the sliding block overcomes the return spring's force, driving the contact roller into contact with the paper, thereby driving the sliding block to slide.

[0017] Preferably, the rotating member includes a second motor, which is fixedly mounted on the sliding block, and a drive shaft of the second motor passes through the sliding block and is coaxially fixed to the contact roller.

[0018] By adopting the above technical solution, the second motor drives the contact roller to rotate, so that the contact roller can fully absorb water when in contact with the wet sponge and can evenly transfer water when in contact with the paper.

[0019] Preferably, a water injection pipe is fixedly provided on the water storage box, one end of the water injection pipe is connected to the interior of the water storage box, and the other end of the water injection pipe is provided with a sealing plug.

[0020] By adopting the above technical solution, the water filling pipe facilitates the operation of adding water to the water storage box, and the sealing plug can prevent water in the water storage box from leaking and external air from entering the water storage box through the water filling pipe, thereby ensuring the normal use of the water storage box.

[0021] Preferably, the water storage box is rotatably matched with the mounting frame, the water injection pipe is fixed on the side wall of the water storage box, and the water injection pipe is bent downward at one end away from the water storage box.

[0022] By adopting the above technical solution, when water needs to be injected, the clamping assembly is first used to clamp the balancing air pipe, and then the water storage box is turned over so that the dripping pipe faces upward, and then the sealing plug is opened, and finally water is injected into the water storage box to prevent outside air from entering the water storage box through the water injection pipe during the water injection process, thereby minimizing the possibility that a large amount of water in the water storage box will drip onto the wet sponge during the water injection process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By installing a water storage box, a wetting sponge, a balancing air pipe, and a clamping assembly, the dripping speed of the dripping pipe can be adjusted, and the degree of wetting of the wetting sponge can be changed, thereby controlling the amount of water on the contact roller and, in turn, the amount of moisture transferred to the paper, effectively preventing the paper from being over-wet or over-dry, ensuring the anti-static effect of paper printing;

[0025] 2. By setting up the chute, sliding block, cam, first motor and reset spring, the contact roller can move up and down. It can accurately wet and reset the contact roller during the interval of paper transmission, ensuring that each paper can get uniform and appropriate moisture, thereby improving the stability and reliability of the equipment.

[0026] 3. By setting a rotatable water storage box, a sealing plug and a water filling pipe, it is possible to prevent outside air from entering the water storage box through the water filling pipe during the water filling process, thereby minimizing the possibility that a large amount of water in the water storage box will drip onto the wet sponge during the water filling process.

[0031] The following is combined with Figure 1-3This application is described in further detail.

[0032] The present application embodiment discloses a paper printing antistatic device. Figure 1 The mounting frame 1 is fixedly mounted on the printing equipment. A water storage box 2 and a moistening sponge 3 are mounted on the mounting frame 1. Several dripping pipes 21 are fixedly mounted vertically at the bottom of the water storage box 2. These dripping pipes 21 connect to the interior of the water storage box 2 and are all located directly above the moistening sponge 3. A balancing air pipe 22 is provided on the water storage box 2, connecting the interior and exterior of the water storage box 2. The balancing air pipe 22 is a flexible hose. The water storage box 2 is equipped with a clamping assembly 23, which is used to tighten or loosen the balancing air pipe 22. Atmosphere enters the water storage box 2 through the balancing air pipe 22, causing water in the water storage box 2 to drip onto the moistening sponge 3 through the dripping pipe 21, maintaining the moistness of the moistening sponge 3. By tightening or loosening the balancing air pipe 22, the clamping assembly 23 changes the speed at which atmosphere passes through the balancing air pipe 22, thereby adjusting the dripping speed and varying the moistening degree of the moistening sponge 3.

[0033] Reference Figure 1 Mounting frame 1 is also provided with a contact roller 44. Specifically, contact roller 44 is a hard, non-absorbent roller, typically stainless steel in this embodiment. A rotating element is provided on contact roller 44 to drive its rotation. One side of contact roller 44's periphery contacts the moistened sponge 3, while the other side contacts the paper on the printing device. The rotating element drives contact roller 44 to rotate, causing it to contact the moistened sponge 3 and pick up moisture. The contact roller 44 then contacts the paper, transferring the moisture to the paper. This increases the surface humidity of the paper and eliminates static electricity.

[0034] In order to facilitate the tightening or loosening of the balance air pipe 22, refer to Figure 2 The clamping assembly 23 includes a threaded rod 231, a fixed clamping block 232, a movable clamping block 233, and a bracket 234. The fixed clamping block 232 and the bracket 234 are both fixedly mounted on the top of the water storage box 2. The movable clamping block is located between the bracket 234 and the fixed clamping block 232, and the balancing air pipe 22 is located between the fixed clamping block 232 and the movable clamping block 233. The threaded rod 231 is rotatably engaged with the bracket 234, and the threaded rod 231 is threadedly engaged with the movable clamping block 233. The threaded rod 231 is used to drive the movable clamping block 233 toward or away from the bracket 234. Specifically, the end of the threaded rod 231 away from the movable clamping block 233 passes through the bracket 234 and is fixedly connected to the knob 2311. When the balancing air pipe 22 needs to be clamped, the threaded rod 231 is rotated, and the movable clamping block 233 moves closer to the fixed clamping block 232 to reduce the ventilation space of the balancing air pipe 22. When it is necessary to loosen the balancing air pipe 22 , the threaded rod 231 is rotated in the opposite direction to move the movable clamping block 233 away from the fixed clamping block 232 , thereby releasing the ventilation space of the balancing air pipe 22 .

[0035] In order to wet and reset the contact roller 44 during the interval between the two papers passing through the antistatic device, refer to Figure 1 and Figure 3 The mounting frame 1 has a vertically defined chute 4, within which a sliding block 41 is slidably mounted. A contact roller 44 is rotatably mounted on the sliding block 41. A sliding assembly 43 is mounted on the mounting frame 1 for driving the sliding block 41 to slide. The rotating member includes a second motor 42, which is fixedly mounted on the sliding block 41. The drive shaft of the second motor 42 passes through the sliding block 41 and is coaxially fixed to the contact roller 44.

[0036] Reference Figure 3 The sliding assembly 43 includes a cam 431, a return spring 432, and a first motor 433. The cam 431 is rotatably mounted on the mounting frame 1 and is positioned above the sliding block 41. The cam 431's peripheral wall abuts against the sliding block 41. The first motor 433 is fixedly connected to the mounting frame 1, and the drive shaft of the first motor 433 is coaxially fixed to the cam 431. The return spring 432 is disposed within the chute 4 and is positioned below the sliding block 41. One end of the return spring 432 abuts against the end wall at the bottom of the chute 4, while the other end abuts against the sliding block 41. The return spring 432 forces the sliding block 41 toward the cam 431.

[0037] Reference Figure 3 The first motor 433 starts to rotate the cam 431, and the sheets of paper pass through the contact roller 44 on the printing unit. When the contact roller 44 has finished transferring moisture to one sheet of paper and the next sheet of paper has not yet arrived, and the protruding portion of the cam 431 no longer contacts the sliding block 41, the elastic force of the return spring 432 drives the sliding block 41 upward, causing the brush roller to contact the moistening sponge 3, and the contact roller 44 to be wetted. Subsequently, the protruding portion of the cam 431 contacts the sliding block 41, driving it downward, returning the contact roller 44 to its original position. When the next sheet of paper passes, it can transfer moisture to the paper again.

[0038] In order to prevent the outside air from entering the water storage box 2 through the water injection pipe 24 during the water injection process, Figure 1 and Figure 2A water injection pipe 24 is fixedly mounted on the water storage box 2. One end of the water injection pipe 24 communicates with the interior of the water storage box 2. A sealing plug 25 is provided at the other end of the water injection pipe 24, which is threadedly engaged with the end of the water injection pipe 24. The water storage box 2 is rotatably engaged with the mounting bracket 1. A handwheel 26 is coaxially fixed to the water storage box 2. The water injection pipe 24 is fixed to the side wall of the water storage box 2, and the end of the water injection pipe 24, away from the water storage box 2, is bent downward. When water injection is required, the clamping assembly 23 is first used to clamp the balancing air pipe 22. The water storage box 2 is then turned over so that the water injection pipe 24 and the drip pipe 21 face upward. The sealing plug 25 is then opened, and finally, water is injected into the water storage box 2. This prevents outside air from entering the water storage box 2 through the water injection pipe 24 during the water injection process, thereby minimizing the possibility that a large amount of water in the water storage box 2 will drip onto the wet sponge 3 during the water injection process.

[0039] The implementation principle of the anti-static device for paper printing in the embodiment of the present application is as follows: when in use, according to the current weather conditions and the humidity requirements of the paper, the distance between the movable clamping block 233 and the fixed clamping block 232 is adjusted by rotating the threaded rod 231 to change the clamping degree of the balancing air pipe 22. When it is necessary to increase the humidity on the surface of the paper, loosen the balancing air pipe 22 to allow air to enter the water storage box 2 faster, thereby speeding up the dripping speed. Conversely, tighten the balancing air pipe 22 to slow down the entry of air into the water storage box 2 and reduce the dripping speed. In this way, the moisture content in the moistening sponge 3 is changed, and the moisture adhered to the contact roller 44 when it contacts the moistening sponge 3 is changed. This makes it easy to control the amount of moisture transferred to the paper by the contact roller 44, and to change the degree of increase in the humidity on the surface of the paper, thereby preventing the paper from being too wet or too dry, and ensuring the anti-static effect of paper printing.

[0040] The first motor 433 drives the cam 431 to rotate, while the second motor 42 drives the contact roller 44 to rotate continuously. Each time a sheet of paper passes through the contact roller 44 and transfers moisture, during the interval between sheets, when the protruding portion of the cam 431 is no longer in contact with the sliding block 41, the return spring 432 pushes the sliding block 41 upward, allowing the contact roller 44 to contact the moistening sponge 3 and absorb moisture. Then, as the paper continues to rotate, the protruding portion of the cam 431 contacts the sliding block 41, pushing the sliding block 41 downward, returning the contact roller 44 to its original position to transfer moisture to the next sheet of paper.

[0041] When the water in the water storage box 2 is insufficient and needs to be replenished, the clamping assembly 23 is first used to completely clamp the balancing air pipe 22, completely sealing it. The water storage box 2 is then rotated, and the sealing plug 25 is opened to allow water to be added. During the filling process, the clamping of the balancing air pipe 22 and the downwardly bent placement of the water injection pipe 24 effectively prevent the ingress of air and the excessive dripping of water.

[0042] 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.
