[0002] Paper-plastic products are a type of product made primarily from paper pulp through processes such as pulping and molding. They combine the environmental friendliness of paper materials with a certain degree of structural strength, making them a common alternative to traditional plastics. Their core characteristics are that the raw materials are renewable and easily degradable, and the processing is relatively environmentally friendly.
[0003] In related technologies, paper-plastic product manufacturing equipment generally includes a forming mechanism, a hot pressing mechanism, a cutting mechanism, and a conveying mechanism. The forming mechanism is used to form wet blanks, the hot pressing mechanism is used to heat-press the wet blanks into dry blanks, the cutting mechanism is used to cut the dry blanks to separate waste and finished products, and the conveying mechanism includes a truss and a conveying robot. The truss extends along the distribution direction of the forming mechanism, the hot pressing mechanism, and the cutting mechanism. The conveying robot can translate along the extension direction of the truss to move to the side of the forming mechanism, the hot pressing mechanism, or the cutting mechanism. At the same time, the conveying robot can enter the forming mechanism, the hot pressing mechanism, and the cutting mechanism to transfer wet blanks from the forming mechanism to the hot pressing mechanism and dry blanks from the hot pressing mechanism to the cutting mechanism. The truss structure occupies a large space, and the material handling and conveying actions of the conveying robot are relatively complex, resulting in low production efficiency. Utility Model Content
[0004] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a paper-plastic product production equipment in which the forming mechanism, hot pressing mechanism, and cutting mechanism are distributed in a straight line, and can transport wet and dry blanks in a straight line, resulting in high production efficiency.
[0005] The paper-plastic product manufacturing equipment according to an embodiment of this application includes: a forming mechanism, a hot pressing mechanism, a cutting mechanism, and a first transfer mechanism.
[0006] A molding mechanism includes a slurry pool, an upper molding die, and a lower molding die. The lower molding die is disposed in the slurry pool, and the upper molding die can be molded and cooperated with the lower molding die to form a wet blank. A hot pressing mechanism, wherein the upper forming mold is movable into the hot pressing mechanism, the hot pressing mechanism being used to hot press a wet blank to form a dry blank; A cutting mechanism includes an upper cutting die and a lower cutting die, wherein the upper cutting die and the lower cutting die can be closed to cut a dry blank; The first transfer mechanism includes a first transfer drive component and a first material picking component. The first transfer drive component is connected to the first material picking component and is used to drive the first material picking component to move along a first linear direction to enter the hot pressing mechanism or the cutting mechanism. The first material picking component is capable of picking up and placing dry blanks. The forming mechanism, the hot pressing mechanism, and the cutting mechanism are distributed along a first straight line.
[0007] The paper-plastic product production equipment according to the embodiments of this application has at least the following beneficial effects: the lower forming mold absorbs the slurry in the slurry pool and causes paper scraps in the slurry to adhere to the concave mold of the lower forming mold. Subsequently, the upper forming mold can descend and close with the lower forming mold to form a wet blank. The upper forming mold absorbs the wet blank and rises, carrying the wet blank away from the lower forming mold. Next, the upper forming mold drives the wet blank to move along a first linear direction and enter the hot pressing mechanism. The upper forming mold places the wet blank in the hot pressing mechanism, and the hot pressing mechanism heats and presses the wet blank to form a dry blank. Immediately afterwards, the first transfer drive assembly drives the first material taking assembly to translate along the first linear direction. The first material taking assembly enters the hot pressing mechanism and takes out the dry blank from the hot pressing mechanism. Then, the first transfer drive assembly drives the first material taking assembly to enter the cutting mechanism along the first linear direction. The first material taking assembly places the dry blank in the cutting lower mold. The upper cutting mold and the lower cutting mold close together to cut the dry blank. In summary, the forming mechanism, hot pressing mechanism, and cutting mechanism are distributed along the first straight line direction. The wet blank is directly transported from the forming mechanism to the hot pressing mechanism along the first straight line direction through the hot pressing upper mold, and the dry blank is directly transported from the hot pressing mechanism to the cutting mechanism through the first transfer mechanism. This simplifies the transfer path between the wet and dry blanks, which only needs to be transported along the first straight line direction, thereby improving the transfer efficiency of the wet and dry blanks, increasing production efficiency, and reducing the space occupied by the equipment.

[0025] Reference Figure 1The paper-plastic product production equipment according to the embodiments of this application includes: a forming mechanism 100, a hot pressing mechanism 200, a cutting mechanism 300, and a first transfer mechanism 400.
[0026] The molding mechanism 100 includes a slurry pool 110, an upper molding die 120 and a lower molding die 130. The lower molding die 130 is disposed in the slurry pool 110, and the upper molding die 120 can be molded and cooperated with the lower molding die 130 to form a wet blank. The hot pressing mechanism 200 and the upper forming mold 120 can be moved into the hot pressing mechanism 200. The hot pressing mechanism 200 is used to hot press the wet blank to form a dry blank. The cutting mechanism 300 includes an upper cutting die 310 and a lower cutting die 320, which can close to cut the blank. The first transfer mechanism 400 includes a first transfer drive assembly 410 and a first material picking assembly 420. The first transfer drive assembly 410 drives and connects to the first material picking assembly 420, and is used to drive the first material picking assembly 420 to move along a first linear direction to enter the hot pressing mechanism 200 or the cutting mechanism 300. The first material picking assembly 420 can pick up and put down the dry blank. The forming mechanism 100, the hot pressing mechanism 200, and the cutting mechanism 300 are distributed along the first straight line direction.
[0027] Understandably, the lower forming die 130 adsorbs the pulp in the pulp tank 110 and causes paper scraps in the pulp to adhere to the concave cavity of the lower forming die 130. Subsequently, the upper forming die 120 descends to close with the lower forming die 130 to form a wet blank. The upper forming die 120 has an adsorption hole connected to an air extraction device. The upper forming die 120 adsorbs the wet blank and rises, carrying the wet blank away from the lower forming die 130. Next, the upper forming die 120 moves the wet blank along a first linear direction and enters the hot pressing mechanism 200. The upper forming die 120 places the wet blank in the hot pressing mechanism 200, and then leaves the hot pressing mechanism 200, which hot-presses the wet blank to form a dry blank. Next, the first transfer drive assembly 410 drives the first material taking assembly 420 to move along the first straight line direction. The first material taking assembly 420 enters the hot pressing mechanism 200 and takes out the dry blank from the hot pressing mechanism 200. Then, the first transfer drive assembly 410 drives the first material taking assembly 420 to enter the cutting mechanism 300 along the first straight line direction, that is, to move between the upper cutting die 310 and the lower cutting die 320. The first material taking assembly 420 places the dry blank on the lower cutting die 320. Then, the first material taking assembly 420 leaves the cutting mechanism 300. The upper cutting die 310 and the lower cutting die 320 close to cut the dry blank, so that the dry blank is separated into finished product and waste. Then, the finished product and waste are taken away manually or by a robot. In summary, the forming mechanism 100, the hot pressing mechanism 200, and the cutting mechanism 300 are distributed along the first straight line direction. The wet blank is directly transported from the forming mechanism 100 to the hot pressing mechanism 200 along the first straight line direction through the hot pressing upper mold 240, and the dry blank is directly transported from the hot pressing mechanism 200 to the cutting mechanism 300 through the first transfer mechanism 400. This simplifies the transfer path of the wet and dry blanks. They only need to be transported along the first straight line direction. There is no need to add a truss or robot on the side. That is, there is no need to turn the wet and dry blanks out in a direction perpendicular to the first straight line direction. As a result, the transfer efficiency of the wet and dry blanks is improved, the production efficiency is increased, and the equipment space occupied is reduced.
[0028] Reference Figure 2 and Figure 3 According to some embodiments of this application, the molding mechanism 100 further includes a first lifting driver 140, a first translation driver 150, a first connecting frame 160, and a second connecting frame 170. The first translation driver 150 is driven to connect the first lifting driver 140, and the first lifting driver 140 is driven to connect the first connecting frame 160. One end of the second connecting frame 170 is connected to the first connecting frame 160, and the other end extends in a direction close to the hot pressing mechanism 200. The second connecting frame 170 can at least partially enter the hot pressing mechanism 200, and the molding upper mold 120 is connected to the second connecting frame 170.
[0029] It is understood that the first translation driver 150 can drive the first lifting driver 140 to translate along the first straight line direction, so as to drive the first connecting frame 160, the second connecting frame 170 and the upper forming mold 120 to translate along the first straight line direction, so that the upper forming mold 120 is aligned with the lower forming mold 130 in the height direction. Subsequently, the first lifting driver 140 drives the first connecting frame 160 to descend, so as to drive the second connecting frame 170 and the upper forming mold 120 to descend, and the upper forming mold 120 and the lower forming mold 130 close to form a wet blank. Next, the first lifting driver 140 drives the first connecting frame 160 to rise, thereby lifting the second connecting frame 170 and the upper forming mold 120, and carrying the wet blank away from the lower forming mold 130. The first translation driver 150 drives the first connecting frame 160 and the second connecting frame 170 to translate along a first linear direction. The second connecting frame 170 at least partially enters the hot pressing mechanism 200, and drives the upper forming mold 120 into the hot pressing mechanism 200. The first lifting driver 140 drives the upper forming mold 120 to descend, thereby placing the wet blank inside the hot pressing mechanism 200. Thus, the first lifting driver 140 and the first translation driver 150 enable the upper hot pressing mold 240 to transfer between the lower forming mold 130 and the hot pressing mechanism 200, and cooperate with the lower forming mold 130 to form the wet blank, and transfer the wet blank to the hot pressing mechanism 200. It is also understood that the second connecting frame 170 extends in the direction close to the hot pressing mechanism 200, and the upper forming mold 120 is fixed to the second connecting frame 170. Thus, before the first connecting frame 160 moves to the side of the hot pressing mechanism 200, that is, before entering the hot pressing mechanism 200, the second connecting frame 170 can drive the upper forming mold 120 into the hot pressing mechanism 200. Therefore, during the process of transferring the wet blank to the hot pressing mechanism 200, only the second connecting frame 170 needs to partially enter the hot pressing mechanism 200. The first connecting frame 160 and the first lifting driver 140 do not need to enter the forming mechanism 100, reducing the possibility of equipment interference and shortening the driving stroke of the first translation driver 150.
[0030] Reference Figure 4 According to some embodiments of this application, the hot pressing mechanism 200 includes a cold extrusion die and a hot pressing die, which are distributed along a first straight line direction, with the cold extrusion die located upstream of the hot pressing die. The cold extrusion die includes a cold extrusion upper die 210 and a cold extrusion lower die 220. The forming upper die 120 can enter between the cold extrusion upper die 210 and the cold extrusion lower die 220 and can transfer the wet blank to the cold extrusion lower die 220. The cold extrusion upper die 210 and the cold extrusion lower die 220 can close and extrude the wet blank. The hot pressing die includes a hot pressing upper die 240 and a hot pressing lower die 250, which can close and hot press the wet blank.
[0031] The paper-plastic product production equipment also includes a second transfer mechanism 500, which includes a second transfer drive assembly 510 and a second material handling assembly 520. The second transfer drive assembly 510 drives the second material handling assembly 520 to move along a first linear direction to enter a cold extrusion mold or a hot pressing mold. The second material handling assembly 520 can pick up and place wet preforms.
[0032] Understandably, the first lifting driver 140 and the first translation driver 150 cooperate to drive the upper forming die 120 into the space between the upper cold extrusion die 210 and the lower cold extrusion die 220, enabling the upper forming die 120 to close with the lower cold extrusion die 220 to transfer the wet preform to the lower cold extrusion die 220. Subsequently, the upper forming die 120 leaves the space between the upper cold extrusion die 210 and the lower cold extrusion die 220, and the upper cold extrusion die 210 and the lower cold extrusion die 220 close to expel some of the moisture from the wet preform. Next, the second transfer drive assembly 510 drives the second material handling assembly 520 into the space between the upper cold extrusion die 210 and the lower cold extrusion die 220. The second material handling assembly 520 approaches the lower cold extrusion die 220 and removes the extruded wet preform. Next, the second transfer drive assembly 510 drives the second material take-up assembly 520 to enter between the hot pressing upper die 240 and the hot pressing lower die 250. The second material take-up assembly 520 places the extruded wet blank into the hot pressing lower die 250. The second material take-up assembly 520 leaves the hot pressing upper die 240 and the hot pressing lower die 250. The hot pressing upper die 240 and the hot pressing lower die 250 close. At least one of the hot pressing upper die 240 and the hot pressing lower die 250 is provided with a heating tube. Thus, when the hot pressing upper die 240 and the hot pressing lower die 250 close, heat can be applied to the wet blank while it is being extruded. The hot pressing of the wet blank is achieved through extrusion force and heat, turning the wet blank into a dry blank. Therefore, by using the cold extrusion upper die 210 and cold extrusion lower die 220 together, the moisture content of the wet blank is first reduced. Then, by using the hot pressing upper die 240 and hot pressing lower die 250 together, the wet blank is hot-pressed to form a wet blank. Thus, the cold extrusion of the cold extrusion upper die 210 and cold extrusion lower die 220 reduces the heat energy required for the hot pressing process of the hot pressing upper die 240 and hot pressing lower die 250, thereby reducing energy consumption. Furthermore, the cold extrusion die and the hot pressing die are also distributed along the first straight line direction, and the second transfer mechanism 500 also drives the second material taking component 520 to enter the cold extrusion die and the hot pressing die along the first straight line direction, thereby reducing the transfer path of the wet blank in the cold extrusion die and the hot pressing die and improving production efficiency.
[0033] Specifically, the hot pressing mechanism 200 also includes a cold extrusion driver 230 and a hot pressing driver 260. The cold extrusion driver 230 drives the upper cold extrusion die 210 or the lower cold extrusion die 220 to move closer or further apart, so as to close or open the die. Similarly, the hot pressing driver 260 drives the upper hot pressing die 240 or the lower hot pressing die 250 to move closer or further apart, so as to close or open the die.
[0034] Reference Figure 4 and Figure 5 According to some embodiments of this application, the second transfer drive assembly 510 includes a second lifting drive member 511, a second translation drive member 512, a second transfer frame 513, and a second guide rail 514. The second guide rail 514 extends along a first straight direction and extends to the side of the cold extrusion die 220 and the hot pressing die 250. The second transfer frame 513 is slidably connected to the second guide rail 514. The second translation drive member 512 drives and connects to the second transfer frame 513. The second lifting drive member 511 is installed on the second transfer frame 513 and drives and connects to the second material handling assembly 520.
[0035] Understandably, the second translation drive 512 drives the second transfer frame 513 to move along the second guide rail 514, so that the second transfer frame 513 moves along the first straight direction to the space between the cold extrusion upper die 210 and the cold extrusion lower die 220 or between the hot pressing upper die 240 and the hot pressing lower die 250, so that the second transfer frame 513 can drive the second lifting drive 511 and the second material taking component 520 to move to the space between the cold extrusion upper die 210 and the cold extrusion lower die 220 or between the hot pressing upper die 240 and the hot pressing lower die 250. Subsequently, the second lifting drive 511 can drive the second material taking component 520 to lift and lower, so that the second material taking component 520 approaches the cold extrusion lower die 220 or the hot pressing lower die 250. The second material taking component 520 can take the wet blank from the cold extrusion lower die 220 or place the wet blank on the hot pressing lower die 250.
[0036] Reference Figure 4 and Figure 5 According to some embodiments of this application, two second guide rails 514 are provided, two second transfer frames 513 are provided, and the second transfer frames 513 correspond one-to-one with the second guide rails 514. The cold extrusion die 220 and the hot pressing die 250 are located between the two second guide rails 514.
[0037] Understandably, the two second guide rails 514 extend along the first straight line direction, and the two ends of the two second guide rails 514 extend to the side of the width direction of the cold extrusion die 220 and the side of the width direction of the hot pressing die 250, respectively. The second transfer frame 513 moves along the second guide rails 514 to the side of the width direction of the cold extrusion die 220 and the hot pressing die 250. The second material taking component 520 is disposed between the two second transfer frames 513, so that the second material taking component 520 can move above the cold extrusion die 220 and the hot pressing die 250.
[0038] Specifically, the hot pressing mechanism 200 also includes a second frame 270, on which both the cold extrusion die and the hot pressing die are fixed and set at the same height. The second guide rail 514 is also set on the second frame 270 to facilitate its arrangement. This allows the second guide rail 514 to be installed on both sides of the cold extrusion lower die 220 and the hot pressing lower die 250 in the width direction. At the same time, when the second transfer frame 513 slides along the second guide rail 514, it can ensure the alignment accuracy of the second material taking component 520 with the cold extrusion lower die 220 and the hot pressing upper die 240, avoiding deformation of the wet blank when the mold is closed due to inaccurate placement of the wet blank, thus improving the quality of the finished product. Furthermore, the lifting stroke of the second transfer frame 513 relative to the cold extrusion lower die 220 and the hot pressing lower die 250 during the material taking and placing process is consistent, which is convenient for control.
[0039] Specifically, the molding mechanism 100 also includes a first frame 180, a slurry pool 110, an upper molding die 120, a lower molding die 130, and a first translation driver 150, all of which are connected to the first frame 180.
[0040] In some other embodiments, the forming mechanism 100 may include one set of hot press molds, or two sets of hot press molds, which can be adjusted according to production needs. That is, both the hot press molds and the cold extrusion molds are detachably connected to the second frame 270.
[0041] Reference Figure 5 According to some embodiments of this application, the second material taking component 520 includes a material taking plate 521 and a protrusion 522. The protrusion 522 is disposed at the lower end of the material taking plate 521. The protrusion 522 can be connected to the cold extrusion die 220 or the hot pressing die 250. The protrusion 522 has a through hole for connecting to a vacuum device so that the protrusion 522 can adsorb the wet blank. The second transfer drive component 510 drives the material taking plate 521.
[0042] Understandably, the second translation drive 512 can drive the take-up plate 521 to move above the cold extrusion die 220 or the hot pressing die 250. At this time, the protrusion 522 at the lower end of the take-up plate 521 is aligned with the die of the cold extrusion die 220 or the die of the hot pressing die 250. The number of protrusions 522 corresponds one-to-one with the die of the cold extrusion die 220 or the die of the hot pressing die 250. The second transfer mechanism 500 drives the take-up plate 521 to rise and fall, so as to drive the protrusion 522 to close with the die of the cold extrusion die 220 or the die of the hot pressing die 250. The protrusion 522 is provided with a through hole for connecting the vacuum equipment. Thus, the protrusion 522 can pick up the wet blank of the cold extrusion die 220, and can also cancel the suction of the wet blank, so that the wet blank falls to the hot pressing die 250.
[0043] Specifically, the protrusion 522 has multiple through holes, and the adsorption force on the wet blank is increased by multiple protrusions 522, so as to improve the adsorption stability of the wet blank.
[0044] Reference Figure 6 According to some embodiments of this application, the first transfer drive assembly 410 includes a first lifting drive 411, a first translation drive 412, a first transfer frame 413, and a first guide rail 414. The first guide rail 414 extends along a first straight direction and extends to the side of the hot pressing die 250 and the cutting die 320. The first transfer frame 413 is slidably connected to the first guide rail 414. The first translation drive 412 drives the first transfer frame 413. The first lifting drive 411 is mounted on the first transfer frame 413 and drives the first material handling assembly 420.
[0045] Understandably, the first translation drive 412 drives the first transfer frame 413 to move along the first guide rail 414, so that the first transfer frame 413 moves along the first straight direction to the space between the upper cutting die 310 and the lower cutting die 320 or between the upper hot pressing die 240 and the lower hot pressing die 250, so that the first transfer frame 413 can drive the first lifting drive 411 and the first material picking assembly 420 to move to the space between the upper cutting die 310 and the lower cutting die 320 or between the upper hot pressing die 240 and the lower hot pressing die 250. Subsequently, the first lifting drive 411 can drive the first material picking assembly 420 to lift and lower, so that the first material picking assembly 420 approaches the lower cutting die 320 or the lower hot pressing die 250. The first material picking assembly 420 can take the dry blank from the lower hot pressing die 250 or place the dry blank on the lower cutting die 320.
[0046] Specifically, one end of the first guide rail 414 extends to the side of the hot-pressing die 250 along the first straight direction, and the other end of the first guide rail 414 extends to the side of the cutting die 320 in the width direction. One end of the first transfer frame 413 is slidably connected to the first guide rail 414, and the other end extends close to the hot-pressing die 250. The first material-taking component 420 is connected to the other end of the first transplanting machine. Thus, when one end of the first transfer frame 413 moves to one end of the first guide rail 414, that is, when it moves to the side of the hot-pressing die 250 in the first straight direction, the other end of the first transfer frame 413 has already driven the first material-taking component 420 to move above the hot-pressing die 250, reducing the travel distance of the first transfer frame 413.
[0047] Specifically, the cutting mechanism 300 also includes a cutting driver 340, which drives the upper cutting die 310 or the lower cutting die 320 to move closer or further apart to close or open the die.
[0048] Specifically, the cutting mechanism 300 also includes a third frame 350, and the upper cutting die 310, the lower cutting die 320, the first lifting drive 411, the first translation drive 412, the first transfer frame 413 and the first guide rail 414 are all connected to the third frame 350.
[0049] Reference Figure 6 According to some embodiments of this application, the first material handling component 420 includes a mounting plate 421 and a plurality of suction cups 422. The suction cups 422 are disposed at the lower end of the mounting plate 421 for adsorbing dry blanks. The first lifting drive component 411 drives the mounting plate 421.
[0050] Understandably, the first translation drive 412 can drive the mounting plate 421 to move above the hot pressing mold 250 or the cutting mold 320. At this time, the suction cup 422 at the lower end of the mounting plate 421 is aligned with the concave mold of the hot pressing mold 250 or the cutting mold 320. The number of suction cups 422 corresponds one-to-one with the concave mold of the hot pressing mold 250 or the cutting mold 320. The first transfer mechanism 400 drives the mounting plate 421 to rise and fall, so as to drive the suction cup 422 to close with the concave mold of the hot pressing mold 250 or the cutting mold 320. The suction cup 422 is connected to the air extraction device. Thus, the suction cup 422 can pick up the dry blank of the hot pressing mold 250, and can also remove the suction of the dry blank, so that the dry blank falls to the cutting mold 320.
[0051] Reference Figure 1 and Figure 6According to some embodiments of this application, a material dropping interval 330 is formed between the forming mechanism 100 and the cutting die 320. The first material taking component 420 also includes a pusher plate 423, which is disposed on the mounting plate 421. The pusher plate 423 is capable of translating relative to the cutting die 320 to push the waste material on the cutting die 320 to the material dropping interval 330.
[0052] Understandably, the other end of the first guide rail 414 extends to the side of the lower cutting die 320 opposite to the hot pressing die 250. After the upper cutting die 310 and the lower cutting die 320 complete the cutting and open the die, the finished product is sucked away by the upper cutting die 310, and the waste material remains in the lower cutting die 320. The first translation drive 412 drives the first transfer frame 413 to move to the other end of the first guide rail 414, so that the push plate 423 on the mounting plate 421 is located in the lower cutting die 320. On the side away from the hot pressing upper mold 240, the first lifting drive 411 drives the mounting plate 421 to descend so that the pusher plate 423 abuts against the upper end of the cutting lower mold 320. The first translation drive 412 drives the mounting plate 421 to move along the first straight line and close to the hot pressing mechanism 200. The pusher plate 423 pushes the waste material of the cutting upper mold 310 to the dropping interval 330. A recycling box can be set at the dropping interval 330 to realize the recycling of waste material.
[0053] Reference Figure 1 According to some embodiments of this application, it also includes a conveyor line 600 and a third transfer mechanism 700. The conveyor line 600 is disposed on the side of the cutting mechanism 300 in the first straight direction, and the third transfer mechanism 700 is used to pick up the finished product at the cutting mechanism 300 and transfer it to the conveyor line 600.
[0054] Understandably, the third transfer mechanism 700 can remove the finished product from the upper cutting die 310 and place it on the conveyor line 600, which then transports the finished product to the next workstation. It should be understood that the conveyor line 600 is located beside the cutting mechanism 300 in the first straight direction, and the third transfer mechanism 700 also transports the finished product along the first straight direction, thereby further improving the product transfer efficiency.
