Description

Technical Field

[0001] This application relates to the field of paint recycling technology, and more particularly to a water-based varnish recycling device. Background Technology

[0002] Water-based varnishes are environmentally friendly coatings that use water as a solvent. They are widely used in the packaging and printing industry, especially in the packaging of food, pharmaceuticals, and tobacco products. In the packaging and printing industry, water-based varnishes are typically used to improve the surface smoothness of products, thereby enhancing the overall aesthetics of printed materials. After product production, water-based varnishes are usually sprayed onto the packaging surface using a spray gun. During this process, some water-based varnishes come into contact with the packaging and cause impact, resulting in dry spraying and wasting the varnish. The wasted varnish falls directly to the ground, causing inconvenience in cleaning. Therefore, this application provides a water-based varnish recovery device to recover the dry sprayed water-based varnish during the spraying process for reuse. Utility Model Content

[0003] In order to recover the water-based varnish wasted due to dry spraying during water-based varnish application, this application provides a water-based varnish recovery device.

[0004] The water-based varnish recovery device provided in this application adopts the following technical solution: A water-based varnish recovery device includes a recovery tank. A grid is provided at the opening of the recovery tank. Two opposing inclined surfaces are provided below the grid. Both inclined surfaces are inclined toward the center of the recovery tank. A buffer container is provided at the bottom of the two inclined surfaces. Several overflow holes are provided through the side wall of the buffer container.

[0005] By adopting the above technical solution, during the spraying of water-based varnish, this device is placed below the spraying device. The water-based varnish wasted due to dry spraying will fall into the recycling tank. The grid will block large impurities. After the water-based varnish enters the recycling tank, it flows along the slope into the buffer container. The buffer container then performs secondary filtration of the water-based varnish. The water-based varnish flowing out of the overflow hole will enter the bottom of the recycling tank, thereby achieving the effect of recycling the water-based varnish.

[0006] Preferably, the higher end of both inclined surfaces is provided with a stepped surface for placing the grille.

[0007] By adopting the above technical solution, the stepped surface facilitates the placement of the grille, improves its stability, and also facilitates its quick disassembly.

[0008] Preferably, a plurality of positioning posts are provided on the lower end surface of both inclined surfaces, and a positioning ring is provided on the outer wall of the buffer container, the positioning ring being sleeved on the outer wall of the positioning posts.

[0009] By adopting the above technical solution, the positioning post and positioning ring facilitate the quick disassembly of the buffer container, thereby promptly clearing the blocked overflow hole.

[0010] Preferably, two overflow plates are vertically arranged inside the recycling tank, the buffer container is located between the two overflow plates, a sedimentation chamber is formed between the two overflow plates, and a recycling chamber is formed on the side of the overflow plate away from the sedimentation chamber. A drain valve is provided on the bottom wall of the sedimentation chamber, and a drain valve is provided on the side wall of the recycling chamber.

[0011] By adopting the above technical solution, the overflow plate can provide the water-based varnish located in the deposition chamber with a certain amount of time for impurities to settle, thereby further improving the purity of the recovered water-based varnish.

[0012] Preferably, both of the bottom walls of the recovery chambers are rotatably connected to rotating impellers.

[0013] By adopting the above technical solution, the rotating impeller can prevent the water-based varnish in the recovery chamber from solidifying due to prolonged static storage.

[0014] Preferably, the opening of the recycling bin is hinged with two hinged plates, and the recycling bin is provided with two sets of locking mechanisms for fixing the hinged plates after they are opened, with each locking mechanism corresponding to one of the hinged plates.

[0015] By adopting the above technical solution, the opening and closing plate can separate the recycling device from the external space when it is not in use, so as to prevent dust and other objects from entering the recycling box and affecting the purity of the recycled water-based varnish. The locking mechanism can keep the opening and closing plate stable after it is opened, so that the recycling device can stably recycle the water-based varnish during the spraying process.

[0016] Preferably, the locking mechanism includes a support rod, a universal joint, a locking pin, and a locking ring. One end of the support rod is hinged to the surface of the opening and closing plate, the universal joint is disposed at the other end of the support rod, the locking pin is hinged to the support rod through the universal joint, and the locking ring is disposed on the side wall of the recycling box.

[0017] By adopting the above technical solution, after the opening and closing plate is opened, rotating the support rod and universal joint allows the locking pin to be aligned with the locking ring. By inserting the locking pin into the locking ring, the opening and closing plate can be locked. The structure is simple and easy to implement.

[0018] Preferably, the opening and closing plate has an adjustment groove on its surface, an adjustment block is slidably connected in the adjustment groove, the support rod is hinged to the adjustment block, and a clearance hole for inserting a locking pin is provided on one side of the adjustment groove.

[0019] By adopting the above technical solution, the locking pin can be inserted into the clearance hole when the opening and closing plate is closed, thereby maintaining the stability of the locking mechanism.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. During the spraying of water-based varnish, this device is placed below the spraying device. The water-based varnish wasted due to dry spraying will fall into the recycling tank. The grid will block large impurities. After the water-based varnish enters the recycling tank, it flows into the buffer container along the slope. The buffer container forms a secondary filtration of the water-based varnish. The water-based varnish flowing out of the overflow hole will enter the bottom of the recycling tank, thereby achieving the effect of recycling water-based varnish. 2. By setting up a grid, a buffer container, and an overflow plate, this application can effectively improve the purity of the recovered water-based varnish. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0025] This application discloses an aqueous varnish recovery device. (Refer to...) Figure 1 and Figure 2 The system includes a recycling bin 1, with two hinged opening plates 6 at the opening of the recycling bin 1 to separate the internal and external spaces of the recycling bin 1. The recycling bin 1 is equipped with two sets of locking mechanisms 7, wherein the locking mechanisms 7 and the opening plates 6 correspond one-to-one to support the opening plates 6 after they are opened, thereby improving stability.

[0026] Reference Figure 1 and Figure 2The locking mechanism 7 includes a support rod 71, a universal joint 72, a locking pin 73, and a locking ring 74. An adjustment groove 61 is provided on the surface of the opening and closing plate 6, and an adjustment block 62 is slidably connected within the adjustment groove 61. One end of the support rod 71 is hinged to the sliding block. The universal joint 72 is located at the end of the support rod 71 away from the adjustment block 62. The locking pin 73 is hinged to the support rod 71 via the universal joint 72. A clearance hole 63 is provided on the surface of the opening and closing plate 6 for the locking pin 73 to enter. When the opening and closing plate 6 is closed, adjusting the position of the adjustment block 62 allows the locking pin 73 to be inserted into the clearance hole 63, thereby maintaining the stability of the locking mechanism 7. The locking ring 74 is located on the outer wall of the recycling box 1. After the locking pin 73 rotates, it can abut against the locking ring 74, thereby maintaining the stability of the opening and closing plate 6 in its open state.

[0027] Reference Figure 1 and Figure 2 The inner wall of the opening of the recycling bin 1 is provided with a grid 2 to block large impurities. Below the grid 2, there are two opposing inclined surfaces 3. Both inclined surfaces 3 are inclined towards the center of the recycling bin 1. The higher end of the inclined surface 3 has a horizontal stepped surface 31 for placing the grid 2.

[0028] Reference Figure 1 and Figure 2 A buffer container 4 is provided at the lower end of the two inclined planes 3. Several overflow holes 41 are provided through the side wall of the buffer container 4. Several positioning posts 32 are provided on the surface of the lower end of the inclined plane 3. Positioning rings 42 are provided on the side wall of the buffer container 4. The positioning rings 42 are sleeved on the periphery of the positioning posts 32, so that the buffer container 4 and the inclined plane 3 form a detachable connection, which makes it easy to clean the blocked overflow holes 41 after the buffer container 4 is removed.

[0029] Reference Figure 1 and Figure 2 The bottom wall of the recycling tank 1 is vertically equipped with two overflow plates 5. The buffer container 4 is located between the two overflow plates 5, and a sedimentation chamber 11 is formed between the two overflow plates 5. A drain valve 13 is provided on the bottom wall of the sedimentation chamber 11 to discharge the deposited impurities. A recycling chamber 12 is formed on the side of the overflow plate 5 away from the sedimentation chamber 11. A drain valve 14 is provided on the side wall of the recycling chamber 12 to discharge the pure water-based varnish. A rotating impeller 15 is rotatably connected to the bottom wall of the recycling chamber 12 to prevent the water-based varnish from solidifying due to prolonged standing in the recycling chamber 12.

[0030] The implementation principle of the water-based varnish recovery device in this application embodiment is as follows: During the spraying of water-based varnish, this device is placed below the spraying device. The water-based varnish wasted due to dry spraying will fall into the recovery tank 1. The grid 2 will block large impurities. After the water-based varnish enters the recovery tank 1, it enters the buffer container 4 along the inclined surface 3. The buffer container 4 forms a secondary filtration of the water-based varnish. The water-based varnish flowing out from the overflow hole 41 will enter the sedimentation chamber 11 at the bottom of the recovery tank 1. When the liquid level in the sedimentation chamber 11 exceeds the overflow plate 5, the upper clear liquid in the sedimentation chamber 11 will overflow the overflow plate 5 and enter the recovery chamber 12. The pure water-based varnish is recovered through the recovery chamber 12, while the deposited impurities are discharged through the drain valve 13, thereby achieving the purpose of recovering water-based varnish.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
