Description

Technical Field

[0001] The present application relates to the technical field of plate roller processing, and in particular to a liquid collecting device for copper plating of gravure plate rollers. Background Art

[0002] During the copper plating process of the gravure printing plate roller, the plate roller needs to be hoisted to the cleaning tank for cleaning. After the plate roller is cleaned, a certain amount of water will be attached. Therefore, a liquid collecting tank is configured on the hoisting mechanism of the plate roller, and the liquid collecting tank can be moved to the bottom of the plate roller to receive the water on the plate roller.

[0003] For example, a Chinese patent document with publication number CN220406613U discloses a residual liquid collection device for copper plating of plate rollers, which includes a bracket, a liquid collecting trough pipe and a drive assembly. The bracket is installed on a gantry lifting mechanism, and the liquid collecting trough pipe is driven and moved to the bracket by the drive assembly.

[0004] However, with regard to the above-mentioned related technologies, when the lifting mechanism drives the plate roller and the liquid collecting tank to move, the liquid in the liquid collecting tank is prone to oscillation due to the effect of inertia. This oscillation phenomenon is likely to affect the stability of the liquid in the liquid collecting tank, increasing the risk of liquid shaking out of the liquid collecting tank and causing leakage, which has an adverse effect on maintaining a clean and dry working environment. Utility Model Content

[0005] In order to reduce the risk of liquid leakage when the liquid collecting tank is moving, the present application provides a liquid collecting device for gravure plate roller copper plating processing.

[0006] The present application provides a liquid collecting device for copper plating of a gravure plate roller, which adopts the following technical solution:

[0007] A liquid collecting device for copper plating of a gravure plate roller comprises: a liquid collecting tank body, a partition and a water absorbing member; the partition is installed in the liquid collecting tank body to divide the inner cavity of the liquid collecting tank body into a first chamber and a second chamber, the first chamber is located on the upper side of the second chamber, and the partition has a connecting hole connecting the first chamber and the second chamber; the water absorbing member is arranged in the first chamber, and the water absorbing member can absorb the moisture entering the first chamber.

[0008] By adopting the above technical solution, the water-absorbing component is placed in the first chamber, so that when the liquid collecting trough body receives water from the plate roller, the water is absorbed by the water-absorbing component, and the water not absorbed by the water-absorbing component falls from the connecting hole of the partition to the second chamber for collection. Therefore, during the movement of the liquid collecting trough body, there is little free water flow in the first chamber, and the water flow in the second chamber is blocked by the water-absorbing component, so that the liquid in the liquid collecting trough body is not easy to shake out of the outside of the liquid collecting trough body, thereby reducing the risk of liquid leakage in the liquid collecting trough body.

[0009] Optionally, a water outlet is provided at one end of the bottom of the liquid collecting tank body, and the water outlet is communicated with the second chamber.

[0010] By adopting the above technical solution, when the water outlet is blocked, the water flow in the liquid collecting tank body is concentrated in the second chamber, and the water flow in the second chamber can be discharged by removing the blockage of the water outlet.

[0011] Optionally, the height of the bottom wall of the liquid collecting tank body gradually decreases in a direction approaching the water outlet.

[0012] By adopting the above technical solution, the change in the height of the bottom wall of the several-page trough body is conducive to guiding the water in the second chamber to the water outlet, thereby improving the drainage efficiency of the liquid collecting trough body.

[0013] Optionally, the liquid collecting device further comprises a water outlet pipe, which is a hose, and one end of which is connected to and communicated with the water outlet.

[0014] By adopting the above technical solution, a water outlet pipe is provided to extend the water outlet channel, and the water outlet pipe can extend into the water receiving container, so that water is not easily splashed out.

[0015] Optionally, a clamping piece is provided on the bottom wall of the liquid collecting tank body, and the clamping piece is used to clamp the water outlet pipe.

[0016] By adopting the above technical solution, when the liquid collecting tank is not draining water, the water outlet pipe is clamped to the clamping member to improve the stability of the water outlet pipe.

[0017] Optionally, the water absorbent member is a water absorbent sponge.

[0018] Optionally, the liquid collecting device also includes a water pressing component, which includes a counterweight pressure roller and a rolling wheel; the rolling wheel is installed at two ends of the counterweight pressure roller that are far away from each other, and the rolling wheel is used to roll on the side of the liquid collecting tank body so that the counterweight pressure roller enters the first chamber to squeeze the water absorbing component.

[0019] By adopting the above technical solution, the rolling wheel rolls on the side of the liquid collecting tank body to drive the counterweight pressure roller to press the water-absorbing sponges at different positions in the liquid collecting tank body, so that the water stored in the water-absorbing sponge can be pressed out and discharged into the second chamber through the connecting hole.

[0020] Optionally, the rolling wheel has an annular groove for the side edge of the liquid collecting trough body to abut against.

[0021] By adopting the above technical solution, the rolling wheel cooperates with the side of the liquid collecting tank body through the annular groove so as to guide the moving direction of the rolling wheel and improve the stability of the rolling wheel.

[0022] Optionally, the water pressure part also includes a central axis and a limit head, the counterweight roller and the rolling wheel are coaxially mounted on the central axis, the rolling wheel can move along the axis of the central axis, the limit head is threadedly connected to both ends of the central axis, and the counterweight roller and the rolling wheel are located between the limit heads at both ends of the central axis.

[0023] By adopting the above technical solution, the water pressure part can be easily disassembled and assembled through the cooperation of the central axis, the counterweight roller and the rolling wheel, and the rolling wheel can be adapted to liquid collecting troughs of different widths by adjusting the distance between the two rolling wheels, thereby improving the adaptability of the water pressure part.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1. The water absorbent is placed in the first chamber to absorb the water in the first chamber, so that the first chamber connected to the outside is not easy to have free water flow, and the excess water can enter the second chamber through the connecting hole for collection. The free water flow in the second chamber is blocked by the water absorbent and is not easy to splash out of the first chamber, thereby reducing the risk of liquid leakage when the liquid collecting tank is moved;

[0026] 2. The rolling wheel on the liquid collecting tank body drives the counterweight pressure roller to squeeze the water-absorbing sponge, so as to press the water stored in the water-absorbing sponge into the second chamber. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application discloses a liquid collecting device for copper plating of a gravure plate roller. Figure 1 and Figure 2 The liquid collecting device for copper plating of gravure printing plate rollers comprises a liquid collecting tank body 1, a partition plate 2 and a water absorbing member 3. The liquid collecting tank body 1 is mounted on a bracket connected to a plate roller hoisting mechanism, and can be driven by a driving component on the bracket to move below the plate roller or staggered with the plate roller. This is a prior art and will not be described in detail here.

[0035] The liquid collecting tank body 1 is in the shape of a square trough with an opening facing upward, and the partition 2 is connected to the liquid collecting tank body 1. The partition 2 is in the shape of a square plate with the same size as the cross-sectional size of the inner cavity of the liquid collecting tank body 1, and can be made of hard materials such as plastic and metal. The partition 2 can be fixed to the inner wall of the liquid collecting tank body 1, and can also be detachably connected to the inner wall of the liquid collecting tank body 1 by bolts. When the partition 2 is installed in the liquid collecting tank body 1, the plate surface of the partition 2 is a horizontal plane, and the partition 2 divides the inner cavity of the liquid collecting tank body 1 into a first chamber 4 and a second chamber 5 arranged up and down, and the first chamber 4 is located directly above the second chamber 5. A plurality of connecting holes 6 are arranged in an array on the partition 2, and the connecting holes 6 pass through the two opposite sides of the partition 2, so that the connecting holes 6 connect the first chamber 4 and the second chamber 5, and the connecting holes 6 located on the outermost side are close to the edge of the partition 2.

[0036] Reference Figure 1 and Figure 2 The absorbent member 3 is in the shape of a long strip, and the cross-sectional dimension of the absorbent member 3 is consistent with the cross-sectional dimension of the partition 2. The absorbent member 3 is placed in the liquid collecting tank body 1 and abuts against the upper surface of the partition 2, and the upper surface of the absorbent member 3 is lower than the upper surface of the tank edge of the liquid collecting tank body 1. The absorbent member 3 can be a water-absorbing material such as water-absorbing rubber and water-absorbing sponge 31, preferably a water-absorbing sponge 31, which can absorb multiple times of its own water, and can release the water again through squeezing and air drying.

[0037] When the liquid collecting tank body 1 moves to the bottom of the plate roller to collect water, the water entering the liquid collecting tank body 1 can be absorbed by the water-absorbing sponge 31, and part of the water not absorbed by the water-absorbing sponge 31 passes through the water-absorbing sponge 31 and the connecting hole 6 on the partition 2 into the second chamber 5 for collection, so that there is less free water flow in the first chamber 4. Therefore, when the liquid collecting tank body 1 moves, the water in the first chamber 4 is absorbed by the water-absorbing sponge 31, and it is not easy for the water cup to shake out of the liquid collecting tank body 1. The water flow in the second chamber 5 is blocked by the water-absorbing sponge 31, and even if it shakes, it is not easy to break through the water-absorbing sponge 31 upwards and move out of the outside of the liquid collecting tank body 1, thereby improving the stability of the liquid collecting tank body 1 in collecting liquid.

[0038] Reference Figure 2 In some embodiments of the present application, in order to facilitate the discharge of the liquid in the liquid collecting tank body 1, the liquid collecting device also includes a water outlet pipe 8. Specifically, a water outlet 7 is provided on one end of the bottom surface of the liquid collecting tank body 1, and the water outlet 7 is connected to the second chamber 5. One end of the water outlet pipe 8 is fixedly connected to the bottom surface of the liquid collecting tank body 1 and is connected to the water outlet 7. The water outlet pipe 8 is a hose and can be made of materials such as waterproof cloth, corrugated pipe, soft metal, etc., preferably a plastic corrugated pipe material. The end of the water outlet pipe 8 away from the water outlet 7 is equipped with a rubber plug. When the liquid collecting tank body 1 is in use, the plug is used to block the end of the water outlet pipe 8 to limit the flow of water from the water outlet pipe 8. When water needs to be drained, the plug is pulled out.

[0039] In order to facilitate the water flow in the second chamber 5 to the water outlet 7, the vertical height of the inner bottom wall of the liquid collecting tank body 1, i.e., the inner bottom wall of the second chamber 5, is gradually reduced in the direction close to the water outlet 7, so as to utilize the height difference to guide the water in the second chamber 5 to the water outlet 7.

[0040] Reference Figure 2 and Figure 3 When the liquid collecting tank body 1 is draining water, the water outlet pipe 8 can extend downward to a container placed on the ground to prevent water from splashing onto the ground. In order to improve the stability of the water outlet pipe 8 when the liquid collecting tank body 1 is receiving water, the bottom wall of the liquid collecting tank body 1 has a clamping member 9 for clamping the water outlet pipe 8.

[0041] Specifically, the clamping member 9 includes a first seat body 91, a second seat body 92 and an elastic portion 93. The first seat body 91 is fixed on the bottom wall of the liquid collecting tank body 1, and the first seat body 91 includes a first pressure rod 911 and an outer rod 912, the first pressure rod 911 extends in the horizontal direction, and there are two outer rods 912, both of which extend in the vertical direction and are respectively fixed at two ends of the first pressure rod 911 that are far away from each other, and the outer rod 912 has an inner cavity extending upward from the bottom surface.

[0042] The second seat body 92 includes a second pressure rod 921 and a vertical rod 922. The second pressure rod 921 is parallel to the first pressure rod 911 and has two ends that are respectively fixed to the second pressure rod 921. The vertical rod 922 corresponds to the outer rod 912 one by one. The end of the vertical rod 922 away from the second pressure rod 921 slides vertically in the corresponding outer rod 912.

[0043] The elastic part 93 is a spring, and the elastic part 93 is located in the inner cavity of the outer rod 912, and the opposite ends of the elastic part 93 are respectively connected to the vertical rod 922 and the inner wall of the outer rod 912, and the elastic part 93 gives elastic force to the vertical rod 922 to move upward. Under the pulling force of the elastic part 93, the distance between the first pressure rod 911 and the second pressure rod 921 is smaller than the outer diameter of the water outlet pipe 8, and the distance between the two vertical rods 922 is larger than the outer diameter of the water outlet pipe 8.

[0044] When the water outlet pipe 8 is stored, the second pressure rod 921 is pulled downward so that the distance between the first pressure rod 911 and the second pressure rod 921 is greater than the outer diameter of the water outlet pipe 8, and the end of the water outlet pipe 8 away from the water outlet 7 is pulled between the first pressure rod 911 and the second pressure rod 921. The downward pulling force on the second pressure rod 921 is released, so that the second pressure rod 921 can move upward to abut against the water outlet pipe 8, and the first pressure rod 911 and the second pressure rod 921 press the water outlet pipe 8 to slightly deform, thereby limiting the water outlet pipe 8.

[0045] Reference Figure 4 In some embodiments of the present application, in order to facilitate squeezing water out of the absorbent sponge 31 when the liquid collecting tank body 1 is draining, the liquid collecting device also includes a water pressing member 10.

[0046] Reference Figure 4 and Figure 5 Specifically, the water pressure member 10 includes a counterweight roller 101, a rolling wheel 102, a central shaft 103 and a stopper 104. The central shaft 103 is in the shape of a circular shaft, and the outer walls of the central shaft 103 at both ends away from each other have external threads. The counterweight roller 101 is in the shape of a cylinder and is coaxially sleeved on the outer wall of the central shaft 103. The counterweight roller 101 can rotate relative to the central shaft 103 and move along the axial direction of the central shaft 103, and the extension length of the counterweight roller 101 along its own axial direction is equivalent to the extension width of the inner cavity of the liquid collecting tank body 1.

[0047] There are two rolling wheels 102, both of which are coaxially sleeved on the outer wall of the central shaft 103. The two rolling wheels 102 are respectively located at opposite ends of the counterweight roller 101. The rolling wheels 102 can rotate relative to the central shaft 103 and move along the axial direction of the central shaft 103, and the outer diameter of the rolling wheels 102 is smaller than the outer diameter of the counterweight roller 101. The outer periphery of the rolling wheel 102 is formed with an annular groove 11 extending along its own circumference. The extension width of the annular groove 11 is consistent with the thickness of the side of the liquid collecting tank body 1. The two rolling wheels 102 are respectively opposite to the opposite side edges of the liquid collecting tank body 1. The rolling wheels 102 are engaged with the side of the liquid collecting tank body 1 through the annular groove 11, so that the rolling wheels 102 can move on the side of the liquid collecting tank body 1 by rotating.

[0048] The limit head 104 is in the shape of a nut, and has two limit heads 104 that are respectively threadedly sleeved on the opposite ends of the central axis 103, and the counterweight roller 101 and the rolling wheel 102 are both located between the two limit heads 104. When the limit head 104 is installed on the central axis 103, it limits the counterweight roller 101 and the rolling wheel 102 from separating from the central axis 103.

[0049] Reference Figure 2 and Figure 4 When the liquid collecting tank body 1 is draining, the water pressing member 10 is placed on the liquid collecting tank body 1, and the two rolling wheels 102 are respectively clamped to the two sides of the liquid collecting tank body 1, and the weighted roller 101 enters the first chamber 4 and presses the water-absorbing sponge 31 downward under the action of its own gravity, and the axis of the weighted roller is parallel to the width direction of the liquid collecting tank body 1. The central axis 103 is pushed to move along the length direction of the liquid collecting tank body 1 to drive the weighted roller 101 to roll over the water-absorbing sponge 31, and press the water in the water-absorbing sponge 31 downward to the second chamber 5 for discharge.

[0050] The implementation principle of the liquid collecting device for copper plating of a gravure plate roller in the embodiment of the present application is as follows: when the liquid collecting tank body 1 receives water from the plate roller, the water entering the first chamber 4 is absorbed by the water-absorbing sponge 31, and the excess water enters the second chamber 5 for collection. When the liquid collecting tank body 1 is drained, the water-absorbing sponge 31 is pressed down by the counterweight pressure roller 101 to press the water-absorbing sponge 31 into the second chamber 5, and at the same time, the water outlet pipe 8 is taken out of the clamping member 9, and the plug of the water outlet pipe 8 is pulled out, so that the water flow in the second chamber 5 is discharged from the water outlet pipe 8.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
