Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing, in particular to an automatic feeding hot pressing mechanism for pulp molded products. Background Art

[0002] The semi-finished pulp molded products formed after forming and drying have a rough and uneven surface, and there will be a little distortion, so the semi-finished products need to be hot-pressed and shaped. However, since the semi-finished products have a rough surface, they cannot be transferred using a suction cup, and the semi-finished products are uneven or distorted and cannot be transferred using a standard fixture. Therefore, the existing hot-pressing shaping solutions are all manual assembly line hot pressing, that is, workers manually transfer the semi-finished products after drying and place them on the hot-pressing lower mold, and then the hot-pressing upper mold moves downward and closes the mold with the hot-pressing lower mold to complete the shaping. After shaping, the products are manually taken out and transferred by workers. The manual hot-pressing solution often requires a large amount of manpower to perform hot-pressing and shaping on the dried pulp molded semi-finished products, which is not only labor-intensive, but also has high labor costs, and low work efficiency and output.

[0003] A few automatic hot pressing solutions use a push-out mechanism to load the material. The hot pressing lower mold pushes out the top plate, which is on the same plane as the pallet for conveying the product. The motor drives the push plate to push the product onto the mold top plate, and then the mold top plate descends, and the product falls onto the hot pressing lower mold. Then the hot pressing upper mold descends and closes the mold with the hot pressing lower mold to complete the shaping. While the hot pressing upper mold ascends, the mold top plate rises to lift up the hot pressed product, and the push plate pushes out the mold lower mold. Although this automatic hot pressing solution can reduce labor intensity and labor costs to a certain extent, this solution can generally only hot press one row of products, and the work efficiency and output are still not ideal. In addition, when the top plate lifts up the product, it is easy to leave an indentation of the top plate on the product surface, which is not suitable for some products with high surface quality requirements.

[0004] In summary, it is necessary to propose a new automatic hot pressing solution to overcome the problems of low working efficiency and output of the above-mentioned existing automatic hot pressing solutions, and the problem of easily leaving top plate indentations on the product surface.

[0078] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0079] Embodiment 1

[0080] like Figures 1 to 16 As shown, this embodiment provides an automatic feeding and hot pressing mechanism 100 for pulp molded products, comprising a frame 1, a hot pressing and shaping mechanism 2, a material receiving mechanism 5, a material taking mechanism 6 and a finished product transferring mechanism 7. Among them, the hot pressing and shaping mechanism 2 is arranged on the frame 1. The hot pressing and shaping mechanism 2 is a conventional device for molding and shaping pulp molded products, which includes a downward drive 21, a hot pressing upper mold 22 and a hot pressing lower mold 23 adapted to the hot pressing upper mold 22. The hot pressing lower mold 23 is movably connected to the frame 1 through a first transfer mechanism 24. The first transfer mechanism 24 is used to drive the hot pressing lower mold 23 to reciprocate between the loading position 3 and the hot pressing position 4. The hot pressing position 4 is located below the hot pressing upper mold 22. When the hot pressing lower mold 23 is in the hot pressing position 4, the hot pressing lower mold 23 and the hot pressing upper mold 22 correspond to each other up and down. The loading position 3 is located on one side of the hot pressing position 4. The downward drive 21 can drive the hot pressing upper mold 22 up and down so that the hot pressing upper mold 22 and the hot pressing lower mold 23 in the hot pressing position 4 are molded or moved away from each other. The receiving mechanism 5 is arranged on the frame 1 and connected with the aforementioned loading position 3. The receiving mechanism 5 can simultaneously receive multiple rows of pulp molding semi-finished products 9 to be hot-pressed (refer to Figure 5, multiple rows of pulp molded semi-finished products 9 are arranged in the horizontal direction). The material taking mechanism 6 includes a solid material clamp 61 and a second transfer mechanism. Multiple solid material clamps 61 are arranged along the arrangement direction of multiple rows of pulp molded semi-finished products 9. Any solid material clamp 61 is movably connected to the frame 1 through the second transfer mechanism. Multiple solid material clamps 61 can fix multiple rows of pulp molded semi-finished products 9 at the same time. Generally, one solid material clamp 61 fixes one row of pulp molded semi-finished products 9. The second transfer mechanism can simultaneously transfer multiple rows of pulp molded semi-finished products 9 clamped on the material taking mechanism 6 from the material receiving mechanism 5 to the loading position 3, and all of them are received by the hot pressing lower mold 23. The finished product transfer mechanism 7 is used to automatically take out all the pulp molded products 11 that have completed hot pressing on the hot pressing lower mold 23 at the same time, and transfer them to the next process. The above-mentioned automatic feeding and hot pressing mechanism 100 for pulp molded products can realize automatic feeding, automatic feeding and automatic hot pressing feeding of multiple rows of pulp molded semi-finished products 9 by setting a receiving mechanism 5 that can simultaneously receive multiple rows of pulp molded semi-finished products 9 to be hot pressed and a material taking mechanism 6 that can clamp multiple rows of pulp molded semi-finished products 9, and configuring a hot pressing lower mold 23 that can automatically reciprocate between the feeding position 3 and the hot pressing position 4. The hot pressing shaping mechanism 2, the receiving mechanism 5 and the material taking mechanism 6 are closely connected and cooperate with each other. Compared with the defect that the existing automatic hot pressing scheme is limited to a single row of pulp molded products, it can realize the automatic transfer and automatic hot pressing of multiple rows of pulp molded products during the hot pressing shaping process, and the work efficiency and output are greatly improved. At the same time, the solid material clamp 61 fixes the pulp molded semi-finished product 9 from the outside, which will not cause indentation to the product, can effectively ensure the product quality, and solves the problem that the top plate indentation is easily left on the product surface when the top plate ejects the product in the existing automatic hot pressing scheme, thereby affecting the product quality.

[0081] In this embodiment, in order to achieve efficient connection between various mechanisms, a discharge mechanism 8 is also provided. The discharge mechanism 8 is provided on the frame 1 and located at the loading position 3. The discharge mechanism 8 can receive all the pulp molded semi-finished products 9 on the material taking mechanism 6. Based on this, when the hot pressing lower mold 23 reaches the loading position 3 under the drive of the first transfer mechanism 24, the hot pressing lower mold 23 is located directly below the discharge mechanism 8, and the discharge mechanism 8 can discharge the received pulp molded semi-finished products 9 downward, so that the pulp molded semi-finished products 9 fall freely into the cavity of the hot pressing lower mold 23 below. After receiving the pulp molded semi-finished products 9, the hot pressing lower mold 23 returns to the bottom of the hot pressing upper mold 22 under the drive of the first transfer mechanism 24, and then the hot pressing upper mold 22 is driven downward by the downward drive 21, so that the hot pressing upper mold 22 and the hot pressing lower mold 23 can be closed, and then the pulp molded semi-finished products 9 in the cavity of the hot pressing lower mold 23 can be hot pressed and shaped.

[0082] Specifically, in this embodiment, Figure 7 to Figure 11As shown, the material discharge mechanism 8 includes an overall frame 81, a supporting frame 82 and a material discharge drive.

Both ends of the first corner support plate 821 and both ends of the second corner support plate 822 are rotatably connected to the overall frame 81; The unloading drive is arranged on the overall frame 81, and the unloading drive can drive the first corner pallet 821 and the second corner pallet 822 to turn synchronously toward each other or turn synchronously in the opposite direction, so that the bracket 82 is switched between the unloading state and the supporting state. In the supporting state, the bottom edges of the first corner pallet 821 and the second corner pallet 822 respectively support the two sides of the pulp molding semi-finished product 9, and in the unloading state, the bottom edges of the first corner pallet 821 and the second corner pallet 822 are away from each other to release the supported pulp molding semi-finished product 9 downward.

[0084] In this embodiment, each row of pulp molding semi-finished products 9 on the receiving mechanism 5 is provided with a plurality of pulp molding semi-finished products 9. Figure 5, multiple rows of pulp molded semi-finished products 9 are arranged in the horizontal direction, and each row of pulp molded semi-finished products 9 extends in the vertical direction. The number of pulp molded semi-finished products 9 in each row is the same, so that the pulp molded semi-finished products 9 on the receiving mechanism 5 are arranged in a matrix of multiple rows and columns. Corresponding to the number of arranged columns of the pulp molded semi-finished products 9 on the receiving mechanism 5, a corresponding number of brackets 82 (the same as the number of columns of the pulp molded semi-finished products 9) can be sequentially arranged in the overall frame 81, and any two brackets 82 are arranged in parallel, and the arrangement interval between any two adjacent brackets 82 does not affect the rotation process of the first corner support plate 821 and the second corner support plate 822 in any bracket 82.

Down; the translation module 65 can be a horizontally arranged cylinder, hydraulic cylinder or electric slide structure, which is arranged on the frame 1 and parallel to the conveyor belt 51 and the support rack 82. The translation module 65 is located above the lifting module 64 and is connected to the lifting module 64. The translation module 65 is used to drive the lifting module 64 and the fixed-distance separation mechanism to reciprocate between the material receiving mechanism 5 and the loading position 3, thereby realizing the automatic transfer of the pulp molding semi-finished product 9 on the material receiving mechanism 5 to the support rack 82 of the loading position 3.

[0091] In this embodiment, considering that the pulp molding semi-finished products 9 on the receiving mechanism 5 can be arranged in a matrix of multiple rows and columns, in order to achieve synchronous clamping of multiple pulp molding semi-finished products 9 in the same row, it is preferred that the solid material clamp 61 adopts a long clamp structure, specifically, as Figure 12 to Figure 16 As shown, the solid material clamp 61 includes an inverted U-shaped top seat 611 and a clamping rod 612. The top of the inverted U-shaped top seat 611 is connected to the spacing cylinder 62, and any fixed distance connecting rod 63 is connected between two adjacent inverted U-shaped top seats 611; in each solid material clamp 61, two clamping rods 612 are arranged in parallel, and the two clamping rods 612 are respectively arranged at the two ends of the bottom of the inverted U-shaped top seat 611, as shown in FIG. Fig.12 and Fig.13 As shown, the two clamping rods 612 are used to clamp the pulp molding semi-finished products 9 to be hot-pressed. The length direction of the two clamping rods 612 is the row extension direction of each row of the pulp molding semi-finished products 9.

[0092] Furthermore, in the present embodiment, the number of the material fixing clamps 61 is generally the same as the number of rows of the pulp molding semi-finished products 9 , and each material fixing clamp 61 clamps a row of the pulp molding semi-finished products 9 .

[0093] In this embodiment, the finished product transfer mechanism 7 includes a vacuum suction nozzle, a finished product receiving mechanism 71 and an air supply component. The vacuum suction nozzle is arranged on the hot pressing upper mold 22, and is used to absorb the pulp molded product 11 that has completed hot pressing when the hot pressing upper mold 22 moves upward, so that the pulp molded product 11 that has completed hot pressing can be separated from the hot pressing lower mold 23; the finished product receiving mechanism 71 is movably connected to the frame 1 through a third transfer mechanism 72, and the third transfer mechanism 72 is used to drive the finished product receiving mechanism 71 to reciprocate between the hot pressing position 4 and the unloading position 10. When the finished product receiving mechanism 71 is in the hot pressing position 4, the finished product receiving mechanism 71 and the hot pressing upper mold 22 correspond to each other up and down to receive the pulp molded product 11 released from the hot pressing upper mold 22, and the unloading position 10 and the loading position 3 are respectively located on different sides of the hot pressing position 4; the air supply component is connected to the above-mentioned vacuum suction nozzle, and the air supply component is used to evacuate the vacuum suction nozzle or release negative pressure, so that the vacuum suction nozzle can absorb the pulp molded product 11 or release the pulp molded product 11. On the basis of the above structure, a blowing nozzle can be arranged on the hot pressing upper mold 22, which is used to apply a downward blowing force to the pulp molded product 11 when the vacuum suction nozzle releases the negative pressure to eliminate the adsorption effect on the pulp molded product 11, so as to accelerate the falling of the pulp molded product 11. The vacuum suction nozzle, the blowing nozzle, etc. in the above finished product transfer mechanism 7 are all existing technologies, which can be embedded in the hot pressing upper mold 22 and do not affect the normal use of the hot pressing upper mold 22.

[0094] In this embodiment, the frame 1 can be an integrated frame or a frame assembly composed of multiple split frames, and the hot pressing shaping mechanism 2, the material receiving mechanism 5, the material taking mechanism 6 and the finished product transfer mechanism 7 are respectively arranged on different split frames. Among the aforementioned multiple split frames, adjacent frames can be stacked up and down or spliced ​​left and right, but not connected, or any two adjacent frames can be fastened and connected by bolts, screws and other components.

[0095] In this embodiment, the third transfer mechanism 72 and the first transfer mechanism 24 are preferably horizontally arranged electric slides, cylinders or hydraulic cylinders.

[0096] The following takes a pulp molded product having six cup holder units arranged in a matrix of three rows and two columns as an example to specifically describe the working process and working principle of the automatic feeding and hot pressing mechanism 100 for pulp molded products.

[0097] After forming and drying, the semi-finished pulp molded cup holders are orderly delivered to the conveyor belt 51 of the receiving mechanism 5. Under the blocking effect of the baffle plate 52, the semi-finished pulp molded cup holders stop one by one on the conveyor belt 51. When the number of semi-finished pulp molded cup holders parked on the continuously rotating conveyor belt 51 reaches a certain number, the lifting module 64 drives the solid material clamp 61 downward, and the two clamping rods 612 at the bottom of the solid material clamp 61 clamp the semi-finished pulp molded cup holders from both sides. The baffle plate lifting drive 53 drives the baffle plate 52 to descend, so that the baffle plate 52 is converted from the blocking state to the avoidance state, and then the translation module 65 is started, driving the lifting module 64 and the fixed-distance separation mechanism to move horizontally, and then pushing the solid material clamp 61, so that the solid material clamp 61 clamps the semi-finished pulp molded cup holder and sends it forward to the support rack 82 of the discharge mechanism 8 (the support rack 82 is in the support state at this time). Then, after the spacing cylinder 62 separates the semi-finished pulp molded cup holder at a certain distance, the lifting module 64 lifts the solid material clamp 61 to release the semi-finished pulp molded cup holder. Then, the hot pressing lower mold 23 is driven by the first transfer mechanism 24 to the loading position 3 and is located below the discharge mechanism 8. Then, the telescopic drive source 87 is started, so that the first corner support plate 821 and the second corner support plate 822 of any support rack 82 are turned over synchronously towards each other (that is, the first corner support plate 821 and the second corner support plate 822 are turned over downward). At this time, the semi-finished pulp molded cup holder will fall freely into the cavity of the hot pressing lower mold 23 below, and then the hot pressing lower mold 23 is translated to the bottom of the hot pressing upper mold 22. The hot pressing upper mold 22 moves downward and closes the mold with the hot pressing lower mold 23 to complete the hot pressing shaping of the semi-finished pulp molded cup holder. After the hot pressing shaping is completed, the pulp molded cup tray is formed. After the hot pressing upper mold 22 and the hot pressing lower mold 23 are opened, the hot pressing upper mold 22 uses a vacuum suction nozzle to adsorb the pulp molded cup tray product on the hot pressing upper mold 22. The hot pressing lower mold 23 moves to the loading position 3 again to receive the new semi-finished product. At the same time, the third transfer mechanism 72 drives the finished product receiving mechanism 71 to the bottom of the hot pressing upper mold 22 in a horizontal motion. The vacuum suction nozzle of the hot pressing upper mold 22 releases pressure, and at the same time, the blowing nozzle blows the pulp molded cup tray product to the finished product receiving mechanism 71 to complete the stacking. Finally, the third transfer mechanism 72 moves the finished product receiving mechanism 71 out in a horizontal motion, and the hot pressing lower mold 23 that receives the new semi-finished product is transferred to the bottom of the hot pressing upper mold 22 again. At the same time, the receiving mechanism 5 and the bracket 82 continue to load materials. Such a cycle and connection operation can greatly improve the hot pressing quality and output of the product.

[0098] The beneficial effects of the automatic feeding and hot pressing mechanism 100 for pulp molded products are as follows:

[0099] (I) Realize multiple rows of products in the hot press: use multiple products close together and push them at the same time, the solid material clamp 61 is connected to the fixed distance separation mechanism, which can separate and position the products according to the distance of each product arrangement on the mold, realize the fixed distance sorting and material separation after automatic conveying, and can accurately sort and send the products into the mold at a fixed distance.

[0100] (2) The material support rack flips and releases the material: the cylinder pushes the rack, the rack drives the gear to rotate, and the material support rack flips with the rotation of the gear, so that the product falls onto the mold below. The structural design is ingenious and the material release effect is good, avoiding the influence of the top plate receiving and releasing the material on the product quality.

[0101] (3) The fully automated structural layout solves the problem of small manual loading capacity and labor shortage.
