Description

Technical Field

[0001] This utility model belongs to the field of mesh coating technology, and specifically relates to a mesh coating device. Background Technology

[0002] Netting is mainly used for aquaculture in large bodies of water such as lakes, reservoirs, and shallow seas. It is primarily made of synthetic materials such as ultra-high molecular weight polyethylene (UHMWPE), polyamide (PA), and polyester (PET). Due to the complex underwater environment of aquaculture, high performance requirements are placed on the netting, such as strength and impact resistance. Furthermore, it is crucial to prevent algae and crustaceans from adhering to and growing on the netting surface, as this would affect the water exchange efficiency within the netting. Current solutions primarily involve coating the netting surface with a coating agent. The main steps in this coating process include dipping the netting in the coating and drying it.

[0003] Chinese patent document CN215396382U discloses a coating and shaping device for deep-sea aquaculture netting, comprising: an unwinding assembly for setting and releasing the netting; a first constant tension adjusting assembly for adjusting the tension of the released netting to a preset constant value; a width adjusting assembly for controlling and adjusting the netting to a suitable width; an impregnation assembly for setting the netting and impregnating it with a coating liquid; a drying assembly for heating and stretching the netting impregnated with the coating liquid; a cooling assembly for cooling the dried coated netting; and a winding assembly for winding the cooled coated netting. The coating heat-setting device disclosed in this application can perform coating heat-setting treatment on deep-sea aquaculture netting. The coating heat-setting can be performed continuously, resulting in a uniform coating on the netting surface, effectively improving the coating quality of the product. The netting structure is stable, the dimensions are controllable, and production efficiency is improved, showing good application prospects in the field of deep-sea aquaculture netting production technology.

[0004] However, after the mesh is impregnated, the mesh is squeezed by the extrusion rollers, causing excess coating solution to flow out. This means that the mesh can only move forward sequentially along its length and be squeezed by the rollers, resulting in low operating efficiency. Utility Model Content

[0005] This utility model provides a mesh coating device that, through machine body dipping and centrifugation, uses an electric hoist mechanism to lift the mesh and remove it for drying, thus quickly completing the mesh coating process. This solves the technical problems of existing mesh coating devices, such as having many complex structural components and being inconvenient to operate.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A mesh coating dipping device includes a body with a hinged cover at the top, an inner shell inside, and a drain pipe at the bottom; it also includes a coating frame placed inside the inner shell, the top of the coating frame having a constricted opening; and a lifting assembly including a bracket located on the outside of the body; and an electric hoist mechanism mounted on the bracket. When the body is in operation, it can drive the inner shell to rotate centrifugally; the height of the coating frame is less than the height of the inner shell; the vertical projection of the bracket coincides with the diameter of the inner shell; when the electric hoist mechanism is in operation, its hook can hook onto a rope attached to the coating frame to lift or lower the coating frame.

[0007] The inside of the dip-coating frame can hold a hanging rod for securing the netting; the hanging rod is placed horizontally and stacked vertically along with the netting inside the dip-coating frame.

[0008] Furthermore, the side of the coating frame is hinged with a frame door; the length of the frame door is less than or equal to the length of the drying rod.

[0009] Furthermore, the distance between the bottom of the frame door and the bottom of the dip-coating frame is at least greater than 1 / 3 of the height of the dip-coating frame.

[0010] Furthermore, the dipping and coating device also includes: a drying rack, located on the outside of the machine body and outside of the support; several sets of hanging grooves are provided on both sides of the drying rack in the height direction, arranged in pairs at intervals; the drying rod can be inserted into the hanging groove for drying the dipped and coated mesh.

[0011] Furthermore, when the electric hoist mechanism is in operation, it can reciprocate within the area along the length direction of the support corresponding to the machine body and the drying rack.

[0012] Furthermore, when the electric hoist mechanism lifts the dip-coated frame after dip coating, the frame door faces the drying rack.

[0013] Furthermore, the dipping device also includes a collection assembly, comprising a collection container located on both sides of the machine body, and outside the support, along with the drying rack; the end of the drain pipe extending into the collection container; and the height of the top of the collection container being lower than the height of the bottom of the machine body.

[0014] Furthermore, the collection assembly also includes a pump located at the top of the collection container, with its input end extending downward into the interior of the collection container and its output end connected to a pipe with a valve.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The machine body contains an inner shell. During mesh coating, the mesh is folded and placed in the coating frame, which is then secured with ropes. The electric hoist is controlled to lift the coating frame by hooking the rope and sending it into the inner shell. The rope is then removed from the hook. The coating solution is added into the machine body until it covers the mesh in the coating frame. After coating, the valve of the drain pipe is opened, and the coating solution in the machine body is discharged. After completion, the machine body is started for centrifugation, which causes the excess coating solution adhering to the mesh in the coating frame to be thrown off. After centrifugation, the machine cover is opened, the rope is hung on the hook, the electric hoist is started to lift the coating frame, and the coated mesh is removed and dried. This coating device has the characteristics of simple structure and convenient operation. Centrifugation can process coated mesh in batches and throw off excess coating, which is more efficient than roller extrusion.

[0016] 2. Since the mesh has a certain length, it can be tied and fixed to the drying rod at intervals along its length, making it easy to neatly load the mesh into the coating frame and to easily and smoothly remove it from the coating frame after coating. The drying rack can be used to hang the treated mesh. When in use, simply insert both ends of the drying rod into the hanging slot. The spacing between the drying rods helps the mesh dry and improves work efficiency. Moreover, the electric hoist can be used to easily lift the coated mesh from the inner shell and transfer it to one side of the drying rack, making it easy to remove the mesh from the coating frame and hang it in the hanging slot, improving the convenience of the operation.

[0017] 3. The collection component is designed to collect the coating solution discharged from the drain pipe after dip coating and before centrifugation, as well as the coating solution discharged through the drain pipe during centrifugation. The collected coating solution can be recycled and reused. When the next batch of mesh is dip coated, it can be pumped back into the machine. This allows the coating solution to be recycled, saves resources, and improves the utilization rate of the coating solution. Attached Figure Description

Detailed Implementation

[0024] To facilitate a better understanding of this utility model, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the protection scope of this utility model, but do not limit the protection scope of this utility model.

[0025] Example 1 A mesh coating apparatus, such as Figures 1-4 As shown, the device includes a body 1 with a hinged cover 11 at the top, an inner shell 12 inside, and a drain pipe 13 at the bottom; it also includes a coating frame 2 placed inside the inner shell 12, with a constriction 21 at the top; and a lifting assembly 3, including a bracket 31 located on the outside of the body 1 and an electric hoist mechanism 32 mounted on the bracket 31. When the body 1 is running, it can drive the inner shell 12 to rotate centrifugally. The height of the coating frame 2 is less than the height of the inner shell 12. The vertical projection of the bracket 31 coincides with the diameter of the inner shell 12. When the electric hoist mechanism 32 is running, its hook can hook the rope attached to the coating frame 2 to lift or lower the coating frame 2.

[0026] The machine body has a motor installed at the bottom. The motor is connected to the inner shell in a conventional way, such as direct connection or belt connection (similar to a drum washing machine). When the motor is running, the inner shell can be driven to rotate centrifugally relative to the machine body through power transmission.

[0027] A controller can be installed on the machine body and operated through the control panel to control parameters such as motor start / stop and running time.

[0028] The dip coating frame can be equipped with a supporting skeleton at the bottom, sides, and top. The skeleton can be made of existing lightweight wood, plastic, etc. The dip coating frame has holes to facilitate the coating solution to enter its interior and come into contact with the mesh, thereby helping to complete the dip coating process. The dip coating frame can be cylindrical when in use.

[0029] The dip-coating frame is used to hold the mesh to be dipped. To use, fold the mesh and place it into the frame through the closed end. The frame has holes to allow the coating solution to enter the frame and contact the mesh during the dip-coating process. A rope can be provided at the closed end to control its size. When placing the mesh, the rope is released to enlarge the opening; after placement, the rope is tightened to reduce the opening size.

[0030] The electric hoist mechanism is an existing product, including a motor, cable, hook, etc. When the motor is running, it can control the winding and unwinding of the cable, thereby controlling the raising or lowering of the hook at the end of the cable. When it is necessary to move the coating frame, there is a hanging ring on the side of the coating frame, and a rope is attached to the hanging ring. By hanging the rope on the hook, the raising or lowering of the coating frame can be controlled when the electric hoist mechanism is running, avoiding manual handling of the netting, improving the convenience of operation, and enhancing the safety of personnel.

[0031] Multiple lifting points can be set on the dip coating frame. The rope passes through the lifting points and is hung on the hook of the electric hoist mechanism, which facilitates the transfer of the dip coating frame, saves manpower, and improves efficiency.

[0032] Instructions for use: Fold the mesh and insert it into the coating frame through the constriction. Open the machine cover and close the drain valve. A rope is threaded onto the hanging ring of the coating frame. Hook the top of the rope onto the hook of the electric hoist mechanism. Start the electric hoist mechanism to move the coating frame up, down, or forward as needed until it enters the inner shell. Remove the rope from the hook and close the machine cover. Add coating solution into the machine until the mesh in the coating frame is submerged. Soak the mesh for a certain period. Then open the drain valve to drain the coating solution from the machine. Start the machine motor. The power transmission causes the inner shell to centrifuge, separating excess coating solution adhering to the mesh and draining it through the drain pipe. After centrifugation, turn off the motor, open the machine cover, hook the rope onto the hook of the electric hoist mechanism, and start the electric hoist mechanism to lift the coating frame out of the inner shell. Then remove the mesh and let it air dry.

[0033] Example 2 The dip coating apparatus also has the following technical features: like Figures 1-2 As shown, a drying rod 22 for securing the netting can be placed inside the coating frame 2; the drying rod 22 is placed horizontally and stacked together with the netting in the vertical direction inside the coating frame 2.

[0034] like Figure 3 As shown, the side of the coating frame 2 is hinged with a frame door 23; the length of the frame door 23 is less than or equal to the length of the hanging rod 22.

[0035] like Figure 3 As shown, the distance between the bottom of the frame door 23 and the bottom of the dip-coating frame 2 is at least greater than 1 / 3 of the height of the dip-coating frame 2.

[0036] The drying rack can be used to secure the mesh to be dipped. Before dipping, the mesh can be tied to both ends of the drying rack at equal intervals along its length with ropes or similar materials. Then, it can be neatly folded up, the opening opened, and placed into the dipping frame. Finally, the opening is tightened. After dipping and centrifugation, the mesh can be removed and hung up to dry.

[0037] The frame door facilitates the removal of the coating from the dip-coating frame; the frame door can be hinged to the dip-coating frame, and a conventional latch can be installed on the non-hinged side so that the frame door can be closed securely and will not loosen; the height of the frame door should not be too low to prevent the coating from sliding out when the frame door is opened.

[0038] Example 3 The dip coating apparatus also has the following technical features: like Figures 1-2 As shown, the dip coating device also includes: a drying rack 4, which is located on the outside of the machine body 1 and on the outside of the support 31; several sets of hanging grooves 41 are provided on both sides of the drying rack 4 in the height direction; the drying rod 22 can be inserted into the hanging groove 41 for drying the dip-coated mesh.

[0039] like Figures 1-2 As shown, when the electric hoist mechanism 32 is running, it can reciprocate within the area along the length of the bracket 31 corresponding to the body 1 and the hanging rack 4.

[0040] like Figures 1-2 As shown, when the electric hoist mechanism 32 lifts the dip-coated frame 2 after dip coating, the frame door 23 faces the drying rack 4.

[0041] The drying rack is used to hang the dip-coated mesh, allowing the coating on the mesh to dry and cure. When in use, use an electric hoist to lift the dip-coated frame out of the machine body and control the electric hoist to move it to one side of the drying rack. Open the frame door and take out the drying rods in sequence and push them into the hanging slots. The mesh is tied to the drying rods, and there can be a certain gap between the drying rods to avoid the mesh from sticking together and affecting the drying and curing.

[0042] The electric hoist mechanism can move horizontally within the area of ​​the machine body and the corresponding support of the drying rack, ensuring that the dip-coated frame with the mesh cloth can be lifted and moved horizontally along the support to the side close to the drying rack. Then, the frame door can be opened to remove the drying rod and hang it on the hanging slot for drying the mesh cloth. After the mesh cloth is dry, it can be removed from the drying rack, the drying rod can be untied, and it can be folded for storage or used directly.

[0043] Example 4 The dip coating apparatus also has the following technical features: like Figure 1 As shown, the dipping device also includes a collection component 5, which includes a collection container 51 located on both sides of the body 1 and the hanging rack 4, and located outside the support 31; the end of the drain pipe 13 extends into the collection container 51; the height of the top of the collection container 51 is lower than the height of the bottom of the body 1.

[0044] like Figure 1 As shown, the collection component 5 also includes a pump 52, which is located on top of the collection container 51, with its input end extending downward into the interior of the collection container 51 and its output end connected to a pipe with a valve.

[0045] The collection container is used to collect the coating solution discharged after dip coating and the coating solution discharged after centrifugation. The coating solution collected in the collection container can be recycled and pumped back into the machine for the next batch of mesh dip coating to avoid waste. The top of the collection container is closed, and the drain pipe extends through the top into the inside of the collection container. An observation window can be set on the top to observe the condition of the coating solution inside, and it can also be opened for use during maintenance and cleaning.

[0046] The drain pipe connects the inside of the machine body to the inside of the collection container. The drain pipe is equipped with a valve, which can be opened and closed as needed. To facilitate the smooth discharge of the coating solution inside the machine body after opening the valve on the drain pipe, the collection container is set at a low position, such as underground. When cleaning the machine body, the end of the drain pipe can be pulled out from the collection container to avoid discharging the cleaning waste liquid into the collection container.

[0047] The collection container and the drying rack are located on the outside of the machine body, which is a more reasonable layout; the collection container is located on the outside of the support frame, which can avoid the support frame being too long.

[0048] The pipe connected to the input end of the pump passes through the top of the collection container and extends into its interior. The output end is connected to a pipe. When it is necessary to deliver the coating container into the machine body, the machine casing is opened, the pipe at the output end is extended into the machine body, and the pump is started to deliver the coating solution collected inside the collection container into the machine body.

[0049] After dip coating is completed, the valve on the drain pipe is opened, and the coating solution for the dip-coated mesh inside the machine flows into the collection container. Then, the machine is started for centrifugation. During centrifugation, the valve on the drain pipe is open, so that the inner shell rotates centrifugally under the action of the motor, and the dip-coating frame also moves centrifugally. This causes the excess coating solution adhering to the mesh to be centrifuged out and discharged into the collection container through the drain pipe. It can be transported back into the machine for the next batch of mesh dip coating for recycling, thereby improving the utilization rate of the coating solution.

[0050] When the motor drives the body of this application, it can drive the inner shell to perform centrifugal motion.

Therefore, they will not be described in detail here. The controllers, control panels, etc. that can be installed on the body are all existing products. Their models, installation, fixing, connection, and usage methods are not innovative points created by this invention. Therefore, they will not be described in detail here.

Its model, installation, connection, and use are all existing technologies. Its functions of reciprocating along the length of the support and the hook moving up and down with the cable have been achieved by existing products.
