Description

Technical Field

[0001] This utility model relates to the field of PVC industrial fabric coating surface technology, specifically, to a device for improving the uniformity of liquid in a surface treatment tank. Background Technology

[0002] Because PVC tarpaulin / membrane structures contain a large amount of plasticizers, which can cause PVC products to become sticky and leach out after prolonged storage or use, it is necessary to coat the surface of the PVC tarpaulin / membrane structure with acrylic or polyvinylidene fluoride to prevent plasticizer leachation. Currently, the surface treatment equipment used in factories is mainly anilox roller transfer coating. The main principle of transfer coating is that the anilox roller is immersed below the surface treatment agent liquid level, carrying the surface treatment agent to the fabric surface for coating. Since the surface treatment agent is a suspension, sedimentation and skin formation can occur after prolonged standing. Factories generally use an external circulation device for the liquid in the tank to reduce uneven coating caused by sedimentation. Existing circulation devices mainly have two types: one is inlet in the middle and outlet from both sides, and the other is inlet from one side and outlet from the other side.

[0003] Existing surface treatment tanks have two circulation methods, both of which have certain drawbacks: The first method involves liquid entering from the bottom center and slowly diffusing to both sides, resulting in a higher deposition of surface treatment agent in the center compared to the sides, leading to a thicker coating in the middle and thinner coating on the edges. The second method involves liquid entering from one side and diffusing to the other, also resulting in a thicker coating on one side and a thinner coating on the other, leading to uneven coating on the left and right sides. Currently, no effective solutions have been proposed to address these issues. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a device to improve the uniformity of liquid in the surface treatment tank, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] An apparatus for improving the uniformity of liquid in a surface treatment tank includes a surface treatment tank with a sliding mechanism inside. The sliding mechanism includes a guide groove located outside the surface treatment tank and an outer slider inside the guide groove. The outer slider is connected to an inner slider via a connecting block. A gear is provided at the bottom of the outer slider, and the gear meshes with a toothed plate. The toothed plate is fixedly connected to the guide groove.

[0007] Furthermore, the gear is connected to the output end of the drive motor via a rotating shaft, and the drive motor is fixed above the outer slider.

[0008] Furthermore, the inner slider is located inside the surface treatment tank.

[0009] Furthermore, the top of the outer slider is provided with an installation groove that matches the connecting block. Limiting blocks are provided on both sides of the bottom of the connecting block. A limiting groove is provided inside the installation groove that matches the limiting block. The installation groove and the connecting block are connected by a magnet.

[0010] Furthermore, the limiting block has grooves on both sides, and a telescopic spring is installed inside the groove. One end of the telescopic spring is connected to the limiting block, and the other end is connected to the locking post. The mounting groove has a locking slot, and the locking post matches the locking slot.

[0011] Furthermore, a turbidity sensor is installed inside the surface treatment tank. The turbidity sensor is electrically connected to the controller, and the controller is connected to the drive motor.

[0012] Furthermore, the surface treatment tank has a water inlet in the middle and water outlets on both sides.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting up a sliding mechanism, the uniformity of the liquid in the surface treatment tank can be significantly improved. The outer slider actively moves, driving the inner slider to move in both forward and reverse directions. This design allows the inner slider to reciprocate within the tank. The movement of the inner slider effectively drives the liquid in the tank to circulate, thereby greatly improving the uniformity of the liquid in the surface treatment tank. This circulation not only reduces the accumulation of sediment but also effectively prevents uneven coating caused by sediment, thus significantly improving the uniformity of liquid coating. In addition, since the liquid in the tank is constantly in circulation, this design can also effectively reduce the problem of surface treatment agent skinning caused by long-term stagnation of the liquid.

[0015] (2) By setting up a turbidity sensor, the concentration of suspended particulate matter in the treatment liquid can be monitored. If the turbidity sensor detects that the turbidity of the treatment liquid is too high, it indicates that the mixing or circulation of the liquid needs to be strengthened to promote the dispersion or sedimentation of particulate matter. At this time, the stirring effect of the liquid can be enhanced by increasing the motor speed. This can not only improve the uniformity of the treatment liquid, but also effectively prevent uneven coating caused by the accumulation of particulate matter, thereby improving the quality and consistency of the product.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, an apparatus for improving the uniformity of liquid in a surface treatment tank is provided.

[0025] Example 1

[0026] like Figures 1-4As shown, the device for improving the uniformity of liquid in a surface treatment tank according to an embodiment of the present invention includes a surface treatment tank 1. A sliding mechanism 2 is provided inside the surface treatment tank 1. The sliding mechanism 2 includes a guide groove 201 located outside the surface treatment tank 1. An outer slider 202 is provided inside the guide groove 201. The outer slider 202 is connected to an inner slider 204 via a connecting block 203. The inner slider 204 is located inside the surface treatment tank 1. A gear 205 is provided at the bottom end of the outer slider 202. The gear 205 meshes with a toothed plate 206. 206 is fixedly connected to the guide groove 201. The gear 205 is connected to the output end of the drive motor 4 through the rotating shaft 3. The drive motor 4 is fixed above the outer slider 202. The top of the outer slider 202 is provided with an installation groove 5, which matches the connecting block 203. The bottom of the connecting block 203 is provided with limit blocks 6 on both sides. The installation groove 5 is provided with a limit groove 7, which matches the limit block 6. The installation groove 5 and the connecting block 203 are connected by a magnet 8, and the attraction of the magnet 8 is used to enhance the stability of the connection. This design is not only simple but also provides additional fixing force to ensure that the connecting block 203 will not easily loosen during use. The limiting block 6 has grooves 9 on both sides, and a telescopic spring 10 is installed inside each groove 9. One end of the telescopic spring 10 is connected to the limiting block 6, and the other end is connected to the locking post 11. The mounting groove 5 has a locking slot 12, and the locking post 11 matches the locking slot 12. The design of the limiting block 6 and the limiting groove 7 ensures that the connecting block 203 is accurately and stably positioned within the mounting groove 5. The grooves 9 on both sides of the limiting block 6 contain the telescopic spring 10 and the locking post 11. Through the elastic force of the telescopic spring 10, the locking post 11 can cooperate with the locking slot 12 on the mounting groove 5 to further fix the connecting block 203 and prevent it from loosening or falling off during use. The surface treatment groove 1 contains a turbidity sensor 13. In this application, the turbidity sensor 13 is model VisoTurb. The 700IQ turbidity sensor 13 is electrically connected to the controller 14, the controller 14 is connected to the drive motor 4, the speed of the drive motor 4 is adjustable, the surface treatment tank 1 has an inlet 15 in the middle, and the surface treatment tank 1 has outlets 16 on both sides.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] In practical applications, by starting the drive motor 4, the gear 205 can be driven to move under the action of the rack, which in turn drives the outer slider 202 to move. The movement of the outer slider 202 drives the inner slider 204 to move. The continuous movement of the inner slider 204 causes the liquid in the tank to flow, reducing uneven coating caused by sedimentation and reducing quality problems. This not only improves the uniformity of the liquid but also reduces uneven coating caused by sediment accumulation. When the inner slider 204 needs to be disassembled and replaced, the locking post 11 can be pressed to retract into the groove 9, and the connecting block 203 can be pulled upward to separate the connecting block 203 from the slider, making it easy to disassemble the inner slider 204. The turbidity sensor 13 can be set to monitor the concentration of suspended particulate matter in the treatment liquid. If the turbidity sensor 13 detects that the turbidity of the treatment liquid is too high, the controller 14 can adjust the speed of the drive motor 4 to make the speed of the drive motor 4 faster, thereby increasing the liquid flow rate inside the surface treatment tank 1 and promoting the dispersion or sedimentation of particulate matter.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, the uniformity of the liquid in the surface treatment tank 1 can be significantly improved by setting the sliding mechanism 2. The outer slider 202 actively moves, driving the inner slider 204 to move in both forward and reverse directions. This design allows the inner slider 204 to reciprocate within the tank. The movement of the inner slider 204 effectively drives the liquid in the tank to circulate, thereby greatly improving the uniformity of the liquid in the surface treatment tank 1. This circulation not only reduces the accumulation of sediment but also effectively prevents uneven coating caused by sediment, thus significantly improving the uniformity of liquid coating. Furthermore, since the liquid in the tank is constantly in circulation, this design can also effectively reduce the problem of surface treatment agent skinning caused by long-term liquid stagnation. In addition, by setting the turbidity sensor 13, the concentration of suspended particulate matter in the treatment liquid can be monitored. If the turbidity sensor 13 detects that the turbidity of the treatment liquid is too high, it indicates that the mixing or circulation of the liquid needs to be strengthened to promote the dispersion or sedimentation of particulate matter. At this point, the stirring effect of the liquid can be enhanced by increasing the speed of the drive motor 4. This not only improves the uniformity of the treated liquid, but also effectively prevents uneven coating caused by the accumulation of particulate matter, thereby improving the quality and consistency of the product.
