Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot pressing, in particular to a kind of paper pulp molded product automatic feeding hot pressing mechanism. BACKGROUND

[0002] After forming, drying the paper pulp molded semi-finished product formed, surface rough, uneven, and there will be a little distortion, so the semi-finished product needs to be hot pressed and shaped. However, due to the rough surface of the semi-finished product cannot be transferred using a suction cup, and the semi-finished product uneven or distorted also cannot be transferred using a standard clamp, so the existing hot shaping scheme is a manual assembly line hot pressing, i.e. the worker manually transfers and places the semi-finished product after drying on the hot pressing lower die, then the hot pressing upper die is lowered and the hot pressing lower die is combined to increase the pressure to complete the shaping, and the shaped product is manually removed and transferred by the worker. The manual hot pressing scheme often needs a large amount of labor to hot press and shape the paper pulp molded semi-finished product after drying, which not only has high labor intensity, but also has high labor cost, low work efficiency and low yield.

[0003] A few automatic hot pressing schemes use a mechanism to push the material out to feed, the hot pressing lower die ejector plate is in the same plane as the product conveying tray, the motor drives the push plate to push the product onto the die ejector plate, then the die ejector plate is lowered, the product falls onto the hot pressing lower die, then the hot pressing upper die is lowered and the hot pressing lower die is combined to increase the pressure to complete the shaping, the hot pressing upper die is raised at the same time as the die ejector plate is raised to lift the hot pressed product, and the product is pushed out of the die lower die by the push plate. Although this automatic hot pressing scheme can reduce labor intensity and labor cost to some extent, this scheme can only hot press one row of products, and the work efficiency and yield are still not ideal. Moreover, when the ejector plate lifts the product, it is easy to leave marks on the surface of the product, which is not suitable for some products with high surface quality requirements.

[0004] In view of the above, it is necessary to propose a new type of automatic hot pressing scheme to overcome the problems of low work efficiency and yield, and easy to leave marks on the surface of the product. SUMMARY

[0076] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0077] The purpose of the present invention is to provide an automatic feeding and hot pressing mechanism for pulp molded products, so as to solve the problems of low working efficiency and output and easy top plate indentation on the product surface in existing automatic hot pressing solutions.

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

[0079] Example 1

[0080] like Figures 1-16 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 is connected to 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 molding semi-products 9 are arranged in horizontal direction). The material taking mechanism 6 comprises multiple fixed material clamps 61, and a second transfer mechanism. The multiple fixed material clamps 61 are arranged in the arrangement direction of the multiple rows of pulp molding semi-products 9. Any fixed material clamp 61 is movably connected to the rack 1 through the second transfer mechanism. The multiple fixed material clamps 61 can simultaneously fix the multiple rows of pulp molding semi-products 9. Generally, one fixed material clamp 61 fixes one row of pulp molding semi-products 9. The second transfer mechanism can simultaneously transfer the multiple rows of pulp molding semi-products 9 clamped on the material taking mechanism 6 from the material receiving mechanism 5 to the feeding position 3, and all the pulp molding semi-products 9 are received by the hot-pressing lower die 23. The product transfer mechanism 7 is used to simultaneously and automatically take out all the pulp molding products 11 on the hot-pressing lower die 23 which have completed hot-pressing, and transfer them to the next process. The above-mentioned pulp molding product automatic feeding and hot-pressing mechanism 100 can realize automatic material receiving, automatic material taking and automatic hot-pressing feeding of the multiple rows of pulp molding semi-products 9, through the arrangement of the material receiving mechanism 5 which can simultaneously receive the multiple rows of pulp molding semi-products 9 to be hot-pressed, the material taking mechanism 6 which can clamp the multiple rows of pulp molding semi-products 9, and the hot-pressing lower die 23 which can automatically reciprocate between the feeding position 3 and the hot-pressing position 4. The hot-pressing and shaping mechanism 2, the material receiving mechanism 5 and the material taking mechanism 6 closely link with each other and cooperate with each other. Compared with the existing automatic hot-pressing scheme which is limited to single row of pulp molding products, the automatic transfer and automatic hot-pressing of the multiple rows of pulp molding products in the hot-pressing and shaping process can be realized, and the work efficiency and yield are greatly improved. At the same time, the fixed material clamps 61 externally fix the pulp molding semi-products 9, which will not cause indentation on the products, and can effectively guarantee the product quality, solving the problem that the existing automatic hot-pressing scheme is easy to leave indentation on the product surface when the top plate ejects the product, thereby affecting the product quality.

[0081] In the embodiment, in order to realize efficient linkage between the mechanisms, the material releasing mechanism 8 is further arranged on the rack 1 and located at the feeding position 3. The material releasing mechanism 8 can receive all the pulp molding semi-products 9 on the material taking mechanism 6. Based on this, when the hot-pressing lower die 23 reaches the feeding position 3 under the drive of the first transfer mechanism 24, the hot-pressing lower die 23 is located directly below the material releasing mechanism 8. The material releasing mechanism 8 can downwardly release the received pulp molding semi-products 9, so that the pulp molding semi-products 9 freely fall into the cavities of the hot-pressing lower die 23 below. After the hot-pressing lower die 23 receives the pulp molding semi-products 9, the hot-pressing lower die 23 returns to the position below the hot-pressing upper die 22 under the drive of the first transfer mechanism 24. Then, the hot-pressing upper die 22 is driven to move downward by the downward driving mechanism 21, so that the hot-pressing upper die 22 and the hot-pressing lower die 23 are closed, and the pulp molding semi-products 9 in the cavities of the hot-pressing lower die 23 are hot-pressed and shaped.

[0082] Specifically, in the embodiment, as shown in FIG. 1, Figures 7-11As shown, the discharging mechanism 8 includes a whole frame 81, a material supporting frame 82 and a discharging drive. The whole frame 81 is a rectangular frame arranged on the rack 1 and connected with the receiving mechanism 5. The inside of the whole frame 81 is hollow. The material supporting frame 82 is arranged in the hollow inside of the whole frame 81. The material supporting frame 82 includes a first corner supporting plate 821 and a second corner supporting plate 822 arranged in parallel with the first corner supporting plate 821. The two ends of the first corner supporting plate 821 and the two ends of the second corner supporting plate 822 are rotatably connected with the whole frame 81. The discharging drive is arranged on the whole frame 81. The discharging drive can drive the first corner supporting plate 821 and the second corner supporting plate 822 to synchronously turn over or reversely synchronously turn over, so as to switch the material supporting frame 82 between the discharging state and the material supporting state. In the material supporting state, the bottom edges of the first corner supporting plate 821 and the second corner supporting plate 822 support the two sides of the pulp molded semi-product 9 respectively. In the discharging state, the bottom edges of the first corner supporting plate 821 and the second corner supporting plate 822 are away from each other, so as to release the supported pulp molded semi-product 9 downward. The structure size of the first corner supporting plate 821 and the second corner supporting plate 822 is preferably completely the same. The corner of the first corner supporting plate 821 and the second corner supporting plate 822 is generally not less than 90 degrees, and the structure of the right angle supporting plate is the best when the corner is 90 degrees.

[0083] In the embodiment, the discharging drive can be a gear meshing transmission assembly or a gear and rack transmission meshing assembly, etc. A motor or a motor can also be directly used as a driving member and connected with the first corner supporting plate 821 and the second corner supporting plate 822. Taking the gear and rack transmission meshing assembly as an example, the discharging drive includes a first gear 83, a second gear 84, a driving gear 85, a driving rack 86 and a telescopic driving source 87. The first gear 83 is connected with the end of the first corner supporting plate 821. The second gear 84 is connected with the end of the second corner supporting plate 822. The second gear 84 and the first gear 83 are located on the same side of the whole frame 81. The driving gear 85 is rotatably arranged on the whole frame 81 and meshes with the first gear 83. The driving rack 86 simultaneously meshes with the driving gear 85 and the second gear 84, and the first gear 83 does not mesh with the driving rack 86. The telescopic driving source 87 can be a pneumatic cylinder, a hydraulic cylinder or an electric sliding table, etc. The telescopic driving source 87 is connected with the driving rack 86 and used to drive the driving rack 86 to linearly reciprocate, so as to synchronously turn over or reversely synchronously turn over the first gear 83 and the second gear 84 under the driving of the driving gear 85, and further switch the material supporting frame 82 between the discharging state and the material supporting state.

[0084] In the embodiment, each row of pulp molded semi-products 9 arranged on the receiving mechanism 5 is provided with a plurality of pulp molded semi-products 9. Referring to Fig. 2, the pulp molded semi-products 9 arranged on the receiving mechanism 5 are arranged in a plurality of rows. Each row of pulp molded semi-products 9 is provided with a plurality of pulp molded semi-products 9. The pulp molded semi-products 9 in the same row are arranged in a staggered manner. Figure 5, the plurality of rows of pulp molded semi-products 9 are arranged in a horizontal direction, each row of pulp molded semi-products 9 extends in a vertical direction, and the number of rows of pulp molded semi-products 9 is the same, so that the pulp molded semi-products 9 on the receiving mechanism 5 are arranged in a matrix of multiple rows and multiple columns. Corresponding to the number of rows of pulp molded semi-products 9 arranged on the receiving mechanism 5, a corresponding number (the same as the number of columns of pulp molded semi-products 9) of material supporting frames 82 can be sequentially arranged in the overall frame 81. Any two material supporting frames 82 are arranged in parallel, and the arrangement spacing between any two adjacent material supporting frames 82 does not affect the rotation process of the first corner supporting plate 821 and the second corner supporting plate 822 in any material supporting frame 82.

[0085] In the embodiment, the plurality of groups of material supporting frames 82 are preferably synchronously operated, and a mode of using one set of material feeding drive for all the material supporting frames 82 is generally adopted to achieve this. Specifically, as shown in Figures 9-11 the end of any first corner supporting plate 821 is provided with a first gear 83, the end of any second corner supporting plate 822 is provided with a second gear 84, the first gears 83 on the first corner supporting plates 821 and the second gears 84 on the second corner supporting plates 822 of any two adjacent groups of material supporting frames 82 are meshed with each other, one driving gear 85 is arranged and is meshed with the first gear 83 in the first group of material supporting frames 82, a driving rack 86 is meshed with the driving gear 85 and any second gear 84, and any first gear 83 is not meshed with the driving rack 86.

[0086] Further, in the embodiment, the teeth on the driving rack 86 are preferably arranged in sections, any section of teeth is meshed with a corresponding second gear 84 or driving gear 85, and the driving rack 86 between any two adjacent sections of teeth is arranged in a spaced manner with the first gear 83, so as to achieve that any first gear 83 is not meshed with the driving rack 86. Based on this, when the driving rack 86 moves horizontally back and forth, it can drive the plurality of groups of material supporting frames 82 to synchronously operate, and the operating states of all the material supporting frames 82 are always consistent.

[0087] In the embodiment, the receiving mechanism 5 includes a conveying belt 51, a material blocking plate 52, and a material blocking plate lifting drive 53. The conveying belt 51 is used to receive and convey the plurality of rows of pulp molded semi-products 9 to be hot pressed. The material blocking plate 52 is arranged between the end of the conveying belt 51 and the feeding position 3. The material blocking plate lifting drive 53 is arranged on the rack 1 and connected with the material blocking plate 52. The material blocking plate lifting drive 53 can be a vertically arranged air cylinder or hydraulic cylinder, which is used to drive the material blocking plate 52 to lift, so as to switch the material blocking plate 52 between a blocking state and an avoiding state. In the blocking state, the material blocking plate 52 is located above the conveying belt 51 to block the pulp molded semi-products 9 on the conveying belt 51 from entering the feeding position 3. In the avoiding state, the material blocking plate 52 is lowered below the conveying belt 51, so that the pulp molded semi-products 9 on the conveying belt 51 can directly enter the feeding position 3.

[0088] In this embodiment, it is preferred that multiple conveyor belts 51 are provided, and the number of conveyor belts 51 provided is the same as the number of columns of the pulp molded semi-finished products 9, and the conveyor belts 51 are aligned one by one with the supporting racks 82, and the pulp molded semi-finished products 9 transported by the same conveyor belt 51 enter the same supporting rack 82.

[0089] Furthermore, it is preferred that when the first corner pallet 821 and the second corner pallet 822 are in the supporting state, the supporting surfaces of the first corner pallet 821 and the second corner pallet 822 are flush with the upper surface of the conveyor belt 51 or slightly lower than the conveyor belt 51, so that after the baffle plate 52 is switched from the baffle state to the avoidance state, the pulp molded semi-finished product 9 on the conveyor belt 51 can be smoothly loaded onto the supporting rack 82.

[0090] In this embodiment, the aforementioned second transfer mechanism includes a fixed-distance separation mechanism, a lifting module 64 and a translation module 65. The fixed-distance separation mechanism includes a spacing cylinder 62 and a spacing connecting rod 63. A plurality of groups of solid material clamps 61 are arranged on the spacing cylinder 62 at intervals, and a spacing connecting rod 63 is arranged between any two adjacent solid material clamps 61; the lifting module 64 can be a vertically arranged cylinder or hydraulic cylinder, etc., which is located above the fixed-distance separation mechanism and is connected to the fixed-distance separation mechanism. The lifting module 64 is used to drive the fixed-distance separation mechanism to rise and fall.

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 move back and forth 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 material 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, Figures 12-16 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. Figure 12 and Figure 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 pulp molding semi-finished products 9.

[0092] Further, in the embodiment, the number of the solid material clamps 61 is generally the same as the number of the rows of the pulp molding semi-products 9, and each of the solid material clamps 61 clamps one row of the pulp molding semi-products 9.

[0093] In the embodiment, the finished product transfer mechanism 7 comprises a vacuum suction nozzle, a finished product receiving mechanism 715 and a gas supply assembly. The vacuum suction nozzle is arranged on the hot pressing upper die 22 and used to adsorb the pulp molding finished product 11 completed by the hot pressing when the hot pressing upper die 22 moves upwards, so that the pulp molding finished product 11 completed by the hot pressing is separated from the hot pressing lower die 23. The finished product receiving mechanism 715 is movably connected with the rack 1 through the third transfer mechanism 72, and the third transfer mechanism 72 is used to drive the finished product receiving mechanism 715 to reciprocate between the hot pressing position 4 and the unloading position 10. When the finished product receiving mechanism 715 is at the hot pressing position 4, the finished product receiving mechanism 715 and the hot pressing upper die 22 correspond to each other in up and down directions, so as to receive the pulp molding finished product 11 released from the hot pressing upper die 22. The unloading position 10 and the feeding position 3 are respectively located at different sides of the hot pressing position 4. The gas supply assembly is connected with the vacuum suction nozzle, and is used to vacuumize or release the negative pressure of the vacuum suction nozzle, so as to adsorb or release the pulp molding finished product 11. On the basis of the above structure, a gas blowing nozzle can also be arranged on the hot pressing upper die 22, which is used to apply a downward blowing force to the pulp molding finished product 10 when the vacuum suction nozzle releases the negative pressure and eliminates the adsorption effect on the pulp molding finished product 10, so as to accelerate the falling of the pulp molding finished product 10. The vacuum suction nozzle and the gas blowing nozzle in the finished product transfer mechanism 7 are all prior art, which can be embedded in the hot pressing upper die 22 and do not affect the normal use of the hot pressing upper die 22.

[0094] In the embodiment, the rack 1 can be an integrated rack or a rack combination composed of multiple split supports. The hot pressing and shaping mechanism 2, the receiving mechanism 5, the material taking mechanism 6 and the finished product transfer mechanism 7 are respectively arranged on different split supports. In the multiple split supports, adjacent supports can be stacked in up and down directions or spliced in left and right directions, or adjacent supports can be tightly connected through bolts, screws and the like.

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

[0096] The working process and working principle of the pulp molding product automatic feeding and hot pressing mechanism 100 will be described in detail below by taking a pulp molding cup holder with six cup holder monomers and arranged in a three-row two-column matrix as an example.

[0097] After the paper pulp molded cup holder semi-finished product is dried by molding, it is sequentially sent to the conveying belt 51 of the receiving mechanism 5. Under the blocking action of the blocking plate 52, the paper pulp molded cup holder semi-finished products are stopped one after another on the conveying belt 51. When the number of the paper pulp molded cup holder semi-finished products stopped on the continuously rotating conveying belt 51 reaches a certain number, the lifting module 64 drives the solid material clamp 61 to move downward, and the two clamping rods 612 at the bottom of the solid material clamp 61 clamp the paper pulp molded cup holder semi-finished products from both sides. The blocking plate lifting drive 53 drives the blocking plate 52 to move downward, so that the blocking plate 52 is switched from the blocking state to the avoiding state. Then the translation module 65 is started to drive the lifting module 64 and the fixed-distance separation mechanism to move horizontally, thereby pushing the solid material clamp 61 to send the paper pulp molded cup holder semi-finished products clamped by the solid material clamp 61 to the material receiving rack 82 (at this time, the material receiving rack 82 is in the material receiving state) of the material placing mechanism 8. Then the fixed-distance separation cylinder 62 separates the paper pulp molded cup holder semi-finished products by a certain distance, and then the lifting module 64 lifts the solid material clamp 61 to release the paper pulp molded cup holder semi-finished products. Then the hot-pressing lower die 23 is driven by the first transfer mechanism 24 to the material placing position 3 and is located below the material placing mechanism 8. Then the extension drive source 87 is started to synchronously flip the first corner supporting plate 821 and the second corner supporting plate 822 of any material receiving rack 82 towards each other (i.e., the first corner supporting plate 821 and the second corner supporting plate 822 are both flipped downward), at this time, the paper pulp molded cup holder semi-finished products will be free-falling into the cavity of the hot-pressing lower die 23 below, and then the hot-pressing lower die 23 moves horizontally to below the hot-pressing upper die 22, the hot-pressing upper die 22 moves downward to combine with the hot-pressing lower die 23 to complete the hot-pressing and shaping of the paper pulp molded cup holder semi-finished products. After the hot-pressing and shaping is completed, the paper pulp molded cup holder finished product is formed, and after the hot-pressing upper die 22 and the hot-pressing lower die 23 are opened, the hot-pressing upper die 22 uses the vacuum suction nozzle to adsorb the paper pulp molded cup holder finished product on the hot-pressing upper die 22. While the hot-pressing lower die 23 moves to the material placing position 3 to receive new semi-finished products, the third transfer mechanism 72 translates the finished product receiving mechanism 71 to below the hot-pressing upper die 22. The vacuum suction nozzle of the hot-pressing upper die 22 is depressurized, and at the same time, the air blowing nozzle blows the paper pulp molded cup holder finished product to the finished product receiving mechanism 71 to complete the stacking. Finally, the third transfer mechanism 72 translates the finished product receiving mechanism 71 out while receiving new semi-finished products, at the same time, the material placing mechanism 5 and the material receiving rack 82 continue to place materials, and the operation is repeated and connected, which can greatly improve the hot-pressing quality and yield of the product.

[0098] The beneficial effects of the above-mentioned paper pulp molded product automatic feeding hot-pressing mechanism 100 are as follows:

[0099] (1) Realize hot-pressing machine multi-row products: multiple products are pushed together at the same time, the solid material clamp 61 is connected with the fixed-distance separation mechanism, which can separate and position the products according to the distance of each product arrangement on the mold, realize automatic conveying and fixed-distance sorting, and accurately sort and send the products into the mold with a certain distance.

[0100] (II) The material support turns over and falls: the cylinder pushes the rack, the rack drives the gear to rotate, the material support turns over with the gear, and the product falls onto the lower mold. The structure design is ingenious, the material falling effect is good, and the influence of the top plate on the product quality is avoided.

[0101] (III) The full-automatic structure arrangement solves the problems of small production capacity and labor shortage in manual feeding.

[0103] The embodiment proposes a kind of paper pulp molded product automatic feeding hot-pressing mechanism 100, it is only different from the embodiment one in that any one group of material support 82 is separately configured a set of material falling drive. Rest structure is same with the embodiment one and will not be described here.

The above examples are only used to help understand the method and core idea of the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed. In conclusion, the content of the present specification should not be understood as a limitation of the present application.
