[0038] like Figures 1 to 6 As shown, a tableware dip coating production line is characterized by including a stacking and storage mechanism 1 for placing products to be dip coated;

[0039] Dip coating conveyor mechanism, used for dip coating the product to be dip coated, the dip coating conveyor mechanism includes

[0040] The material handling and transfer mechanism 21 is used to remove the product to be dip-coated from the stacking storage structure and move it to...

[0041] The dip coating mechanism 22 is provided with a transmission line, which includes two spaced rotating shafts 221. Two sprockets 222 are provided at both ends of the rotating shafts 221 respectively. A corresponding conveyor chain 223 is provided on the outside of the sprockets 222. A fixed clamping structure 224 is provided on the conveyor chain 223. The clamping structure 224 moves in a ring along the direction of the conveyor chain 223 under the action of the conveyor chain 223.

[0042] Between the two sprockets 222, there is an immersion coating tank structure 23, a paint recovery tank 24 and an oven 25. The product passes through the immersion coating tank structure 23, the paint recovery tank 24 and the oven 25 in sequence under the clamping structure 224.

[0043] The receiving mechanism 3, located on the side of the dip coating conveyor, is used to collect the dip-coated products.

[0044] Under the action of the material transfer mechanism 21, the product to be processed is taken out from the stacking storage mechanism 1 and fixed by the clamping structure 224. Then, under the action of the conveyor chain 223, it passes through the dip coating tank structure 23, the paint recovery tank 24 and the drying oven 25 in sequence, thereby completing the dip coating process of the product surface. At this time, the whole process is automated, so the production efficiency is high.

[0045] At this point, because the product needs to be clamped by the clamping structure 224, part of the product will be fixed by the clamping structure 224 during the first dip coating process, thus preventing it from contacting the coating. Therefore, in order to achieve full dip coating of the product, in this embodiment, the dip coating conveying mechanism is provided in two sets, connected in series between the stacking storage mechanism 1 and the receiving mechanism 3. After the two dip coating conveying mechanisms are connected in series, the material handling and transfer mechanism 21 of the latter dip coating conveying mechanism can remove the product after the first dip coating and change the clamping position, so that the product can be fully covered with coating after two dip coatings.

[0046] Since the product to be dipped is taken out by the material transfer mechanism 21, it is necessary to arrange the product to be dipped neatly at this time. In this embodiment, the stacking storage mechanism includes a base 14, a rotating seat 15 on the upper side of the base, a positioning fixture 11 on the upper side of the rotating seat 15, a number of positioning grooves 12 adapted to the partial shape of the product in parallel on the positioning fixture, and a vertical stacking structure 13 for controlling the up and down movement of the positioning fixture on the upper side of the rotating seat. The base is equipped with a structure for driving the rotating seat to rotate, such as a motor. Under the action of the motor, the rotating seat rotates on the upper side of the base (of course, corresponding shafts and bearings are provided). Two positioning fixtures are set on the upper side of the rotating seat. During the rotation, different positioning fixtures can rotate to the side close to the material transfer mechanism, thereby taking out the product in the corresponding positioning fixture. At the same time, the vertical stacking structure 13 is a vertically set cylinder or electric rod, etc., used to control the up and down movement of the positioning fixture 11. Several positioning grooves 12 are provided on the upper side of the positioning support. The product to be dipped is placed in the positioning groove 12. At this time, the positioning groove 12 does not completely cover the product, and part of the product is still exposed, so that the material transfer mechanism can easily take out the product at the position of the positioning groove 12.

[0047] The material transfer structure is used to transfer products. In this embodiment, the material transfer mechanism 21 includes a horizontal moving structure 211 fixed by a bracket. A horizontal moving plate is provided on the upper side of the horizontal moving structure 211, and a vertical moving structure 212 is provided at the position of the horizontal moving plate. A vacuum suction cup 213 for fixing the product is provided on the lower side of the vertical moving structure 212. At this time, a horizontal guide rail is provided on the upper side of the bracket, and a slider is provided on the upper side of the horizontal guide rail. The horizontal moving plate is connected to the horizontal guide rail through the slider. The upper side of the horizontal moving plate is fixed to a synchronous belt by a fixing member. A horizontal motor is also provided on the side of the bracket. Under the action of the horizontal motor, the horizontal moving plate moves horizontally on the upper side of the horizontal guide rail. The vertical moving structure 212 adopts a cylinder or electric cylinder. A material picking clamp is provided on the lower piston rod or movable rod. The material picking clamp is provided with a plurality of arranged vacuum suction cups 213. The number of vacuum suction cups 213 is the same as the number of positioning slots 12 of the positioning fixture 11, so that all products in the positioning slots 12 can be picked up at once, improving the picking efficiency.

[0048] The clamping structure 224 clamps and fixes the product during the dip coating process, allowing the product to move with the conveyor chain 223. In this embodiment, the clamping structure 224 includes a connecting plate 2241 fixed to the conveyor chain 223. A fixing rod 2242 is provided between the two connecting plates 2241 at the same position of the two sprockets 222. A moving rod 2243 is provided on the side of the fixing rod 2242. The fixing rod 2242 has a through hole. A connecting post 2244 is provided at the position of the through hole. The end of the connecting post 2244 is fixed to the moving rod 2243. A limiting boss is provided at the end of the connecting post 2244. A compression spring 2246 is sleeved on the outside of the connecting post 2244. The two ends of the spring 2246 abut against the limiting boss and the side of the fixing rod 2242, respectively. At this time, under the action of spring 2246, the fixed rod 2242 and the movable rod 2243 are pressed together, thereby clamping the product between the fixed rod 2242 and the movable rod 2243. If the product clamping position is on a plane, it can be clamped and fixed directly. If the product has a part protrusion, a corresponding groove can be set on the side of the fixed rod 2242 or the movable rod 2243 to better fix the product.

[0049] Under the action of spring 2246, the fixed rod 2242 and the moving rod 2243 are tightly pressed together. However, during the process of picking up and putting down products, it is necessary to move the fixed rod 2242 and the moving rod 2243 apart to create a gap between them, which facilitates the removal and insertion of products. Therefore, in this embodiment, the sprocket 222 is provided with an opening structure 26 on its side to open the clamping structure 224. The opening structure 26 includes an opening cylinder 261, and the piston rod of the opening cylinder 261 is connected to an opening rod 262. The end of the opening rod 262 is tapered. The contact surface end of the fixed rod 2242 and the moving rod 2243 is provided with an opening hole 2245. When the opening rod 262 is inserted into the opening hole 2245 under the action of the opening cylinder 261, the fixed rod 2242 and the moving rod 2243 separate at the contact surface position. Under the action of the opening cylinder 261, the opening rod 262 moves laterally. When the fixed rod 2242 and the moving rod 2243 move to the side position of the opening rod 262, the opening rod 262 is inserted into the opening hole 2245 at the end of the contact surface of the fixed rod 2242 and the moving rod 2243. At this time, the outer diameter of the opening rod 262 is smaller than the inner diameter of the opening hole 2245, so that the end of the opening rod 262 can be easily inserted into the opening hole 2245. However, the outer diameter of the opening rod is larger than the inner diameter of the opening hole 2245. After the opening rod 262 is fully inserted into the opening hole 2245, the fixed rod 2242 and the moving rod 2243 can be separated at the contact surface, thereby realizing the clamping and fixing of the product, and its removal after fixing.

[0050] The surface of the product needs to be dip-coated, therefore the product needs to be dip-coated with paint. In this embodiment, the dip-coating tank structure 23 includes a vertically movable dip-coating tank 231, which contains paint. The lower side of the dip-coating tank 231 is provided with a dip-coating control structure for controlling the vertical movement of the dip-coating tank 231. The dip-coating control structure is a vertically arranged cylinder or electric cylinder used to control the vertical movement of the dip-coating tank 231. After the clamping structure 224 moves the product to the upper position of the dip-coating tank 231, the dip-coating tank 231 is then controlled to move upward, thereby dipping the product into the paint.

[0051] After dipping in the coating, some coating residue will remain on the surface of the product. If not removed, it will lead to poor product quality. Therefore, it is necessary to recycle the excess coating. In this embodiment, the coating recycling tank 24 includes a tank body 241. The tank body 241 is set in a V-shaped space for collecting coating. The tank body 241 is provided with two air pipes 242 arranged in parallel. The air pipes 242 are provided with air outlets. The air outlets of the two air pipes 242 face different directions. A shaking structure 243 is also provided between the air pipes 242 and the dipping tank structure 23. The shaking structure 243 includes a shaking cylinder 2431 fixed on the upper side of the tank body 241. The piston rod of the shaking cylinder 2431 is connected to a shaking rod 2432. The shaking rod 2432 strikes the conveyor chain 223 or the clamping structure 224 under the action of the shaking cylinder 2431. Under the action of the vibrating cylinder 2431, the vibrating rod 2432 strikes the conveyor chain 223 or the clamping structure 224, so that the product that has moved to the position vibrates, thereby allowing excess paint on the product surface to be sprayed off. At the same time, air nozzles facing different angles are also provided on the side to blow off the residual paint on the product surface, and at the same time, the surface can be initially dried.

[0052] After removing excess paint, drying is required. In this embodiment, the oven 25 includes an upper chamber and a lower chamber, forming a transmission channel 251 between them. The clamping structure 224, after fixing the product, passes through the transmission channel 251 via a conveyor chain 223. In this case, a conventional oven 25 is used, with an upper and lower chamber positioned vertically to improve the drying effect.

[0053] Finally, after drying, the products need to be collected. In this embodiment, the receiving mechanism 3 includes a discharge conveyor belt 31 located on the side of the conveyor chain 223. A material transfer mechanism 21 is provided between the discharge conveyor belt 31 and the conveyor chain 223 to move the products fixed by the clamping structure 224 of the conveyor chain 223 to the position of the discharge conveyor belt 31.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
