[0032] like Figures 1 to 4 As shown, the automatic hot pressing and shaping feeding device of the embodiment of the utility model includes a main frame 1, and a product conveying mechanism 2, a fixed-distance dividing mechanism 3 and a flipping supporting mechanism 4 installed on the main frame 1, and the flipping supporting mechanism 4 is arranged on the discharge side of the product conveying mechanism 2; the fixed-distance dividing mechanism 3 includes a translation structure 31, a lifting structure 32 and a plurality of dividing components 33, the translation structure 31 is arranged on the upper side of the product conveying mechanism 2 and the flipping supporting mechanism, the lifting structure 32 is connected to the translation structure 31, and the plurality of dividing components 33 are installed at the lower end of the lifting structure 32.

[0033] Multiple material dividing components 33 are distributed in sequence along the conveying path of the product conveying mechanism 2, and the material dividing components 33 are extended and arranged in parallel to the width direction of the product conveying mechanism 2. The material dividing components 33 are used to position and cooperate with the pulp molded product 5; the flipping support mechanism 4 includes a first driver 41 and multiple support plates 42, and the multiple support plates 42 are rotatably assembled relative to the main frame 1, and the rotation axis of the support plate 42 is parallel to the conveying path of the product conveying mechanism 2. The first driver 41 is connected to the support plate 42 in a transmission manner so that the support plate 42 can switch between a supporting state and a unloading state.

[0034] The automatic hot pressing shaping feeding device adopts the design form of a main frame 1, a product conveying mechanism 2, a fixed-distance material dividing mechanism 3 and a flipping material supporting mechanism 4, wherein the product conveying mechanism 2, the fixed-distance material dividing mechanism 3 and the flipping material supporting mechanism 4 are all installed on the main frame 1, the flipping material supporting mechanism 4 is arranged on the discharge side of the product conveying mechanism 2, and the translation structure 31 of the fixed-distance material dividing mechanism 3 is arranged on the upper side of the product conveying mechanism 2 and the flipping material supporting mechanism. When working, the pulp molded product 5 moves with the product conveying mechanism 2 until it stops at the discharge side. The fixed-distance material dividing mechanism 3 can not only position the pulp molded product 5 according to a certain spacing, but also transfer the pulp molded product 5 to the flipping material supporting mechanism 4, which is located above the hot pressing lower mold, so that the batch of pulp molded products 5 can accurately complete the hot pressing shaping feeding process.

[0035] The fixed-distance dividing mechanism 3 includes a translation structure 31, a lifting structure 32 and a plurality of dividing components 33. The lifting structure 32 is connected to the translation structure 31, and the plurality of dividing components 33 are installed at the lower end of the lifting structure 32. Since the plurality of dividing components 33 are distributed in sequence along the conveying path of the product conveying mechanism 2, and the dividing components 33 are extended and arranged parallel to the width direction of the product conveying mechanism 2, the plurality of dividing components 33 can be used to arrange the pulp molded products 5 in sequence along the conveying path. The dividing components 33 can reliably position the pulp molded products 5 in the same row, thereby ensuring that the pulp molded products 5 can be accurately transferred to the flipping support mechanism 4.

[0036] In addition, the flip support mechanism 4 includes a first driver 41 and a plurality of support plates 42. The plurality of support plates 42 are rotatably assembled relative to the main frame 1, and the rotation axis of the support plates 42 is parallel to the conveying path of the product conveying mechanism 2. The first driver 41 is connected to the support plates 42 in a transmission manner. The first driver 41 drives the support plates 42 to be in a supporting state, which can smoothly receive the pulp molded product 5 and make the material distribution component 33 release the product. When the hot pressing lower mold moves to the bottom of the flip support mechanism 4, the first driver 41 drives the support plates 42 to flip downward until the material is unloaded. At this time, the pulp molded product 5 falls freely into the hot pressing lower mold below, and the hot pressing lower mold moves to the bottom of the hot pressing upper mold. The hot pressing upper mold and the hot pressing lower mold are pressed together to complete the shaping. It can realize the accurate sorting and feeding of multiple rows of products into the mold, avoiding the problems of high labor cost and low feeding efficiency, and is more suitable for products with high surface quality requirements.

[0037] In this embodiment, a fixed-distance guide rail 34 is provided at the lower end of the lifting structure 32, and the fixed-distance guide rail 34 is extended and arranged along the conveying path of the product conveying mechanism 2. A plurality of material distribution components 33 are adjustably mounted on the fixed-distance guide rail 34, and a fixed-distance connecting rod 35 is also connected between two adjacent material distribution components 33. The fixed-distance connecting rod 35 ensures that the material distribution components 33 are arranged at a fixed distance along the conveying path. In addition, a second driver 36 is also installed on the fixed-distance guide rail 34, and the second driver 36 is connected to the material distribution component 33 in a transmission manner. Specifically, the second driver 36 is a cylinder, and the pulp molded product 5 is driven by the second driver 36 to be separated at a certain distance, ensuring that the pulp molded product 5 is accurately positioned with the hot pressing lower mold below.

[0038] As a further preferred solution, the material dividing assembly 33 includes a U-shaped groove 331 and two push rods 332. The U-shaped groove 331 is installed on the lower side of the fixed distance guide rail 34 with its opening facing downward. The two push rods 332 are respectively fixedly connected to the two side edges of the U-shaped groove 331. The distance between the two push rods 332 forms a positioning space for cooperating with the pulp molded product 5. The opening of the U-shaped groove 331 faces downward to avoid interference with the pulp molded product 5. The distance between the two push rods 332 matches the width of the pulp molded product 5, which can accurately position the product.

[0039] In addition, a blocking structure 6 is installed near the discharging side of the product conveying mechanism 2, and the blocking structure 6 includes a third driver 61 and a blocking plate 62. The third driver 61 is fixedly arranged on the main frame 1, and the blocking plate 62 is installed at the driving end of the third driver 61. The blocking plate 62 is used to cooperate with the pulp molded product 5. The pulp molded product 5 on the product conveying mechanism 2 is blocked by the blocking plate 62, so that the products stop on the product conveying mechanism 2 one by one. When the number of products parked reaches a certain amount, the material dividing assembly 33 is controlled to move downward to position the products.

[0040] In this embodiment, the flip support mechanism 4 further includes a fixed frame 43, a plurality of support plates 42 are rotatably mounted on the inner side of the fixed frame 43, and a first driver 41 is arranged on the outer side of the fixed frame 43. Specifically, an even number of support plates 42 are arranged, and two support plates 42 facing each other form a group, and the interval between two support plates 42 in the same group is used to accommodate the pulp molded product 5. A rack 44 is slidably mounted on the outer side of the fixed frame 43, and the length direction of the rack 44 is perpendicular to the length direction of the support plate 42. The first driver 41 is connected to the rack 44, and a synchronous gear 45 is assembled between the rack 44 and the support plate 42.

[0041] One support plate 42 of the same group is connected to the synchronous gear 45 for rotation prevention, and another support plate 42 of the same group is connected to the driven gear 46 for rotation prevention, and the driven gear 46 is meshed with the synchronous gear 45 of the adjacent group. Figure 4 As shown, the support plate on the left side of the same group is connected to the synchronous gear 45, and the support plate on the right side of the same group is connected to the driven gear 46. The synchronous gear 45 and the support plate on the left side can be driven to rotate synchronously by means of a gear rack mechanism. Accordingly, under the meshing relationship between the driven gear 46 and the synchronous gear 45 of the adjacent group, the driven gear 46 and the support plate on the right side rotate in opposite directions, thereby achieving the purpose of the two support plates 42 in the same group completing the downward flipping action.

[0042] In addition, the support plate 42 is an L-shaped plate, and the support plate 42 has a bottom edge section and a side edge section that are fixedly connected. In the supporting state, the bottom edge section 421 of the support plate cooperates with the pulp molded product 5 for supporting, and the side edge section 422 of the support plate cooperates with the pulp molded product 5 for stopping; in the unloading state, the support plate 42 flips over and separates from the pulp molded product 5. When the support plate 42 flips downward, the pulp molded product 5 falls to the hot pressing lower mold under its own gravity. After the hot pressing shaping is completed, the upper and lower molds are opened, and the upper mold uses vacuum to adsorb the product on the upper mold, and the lower mold moves out to continue to receive new semi-finished products. Then the material receiving device is translated to the bottom of the hot pressing upper mold, and the upper mold blows the product onto the material receiving device to complete the stacking. Avoiding the use of the mold top plate to eject the hot pressed product and causing top plate indentations is more suitable for products with high surface quality requirements.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
