The hanging conveying line is arranged on the side of the belt conveying mechanism. A fixed frame plate is provided at the front end of the belt conveying mechanism. A sliding plate is installed on the top of the fixed frame plate. A pushing mechanism is arranged inside the fixed frame plate. A plurality of hanging rods are evenly installed inside the hanging conveying line. A material supporting mechanism is fixedly installed at the bottom end of the hanging rod.

[0007] In the above technical solution, preferably, the path groove is arranged in an inclined shape, and the horizontal height in the middle of the path groove is higher than the horizontal heights on both sides thereof. The middle of the path groove corresponds to the fixed frame plate.

[0008] In the above technical solution, preferably, the material supporting mechanism includes a fixing plate, the fixing plate is fixedly connected to the suspension rod, bumps are installed at two end corners of the fixing plate away from the belt conveying mechanism, an activity groove is formed on the surface of the bump, a landslide plate is arranged above the fixing plate, first convex columns are installed on both sides of the end face of the landslide plate away from the belt conveying mechanism, the surface of the first convex column is slidably installed in the activity groove, a rectangular groove is formed in the middle of the other end of the landslide plate, a rectangular block is installed in the rectangular groove through a rotating shaft, a sliding column is installed at the end of the rectangular block, and the sliding column is slidably installed in the path groove.

[0009] In the above technical solution, preferably, two vertical plates are symmetrically installed on the surface of the fixing plate, two through grooves are symmetrically formed on the surface of the landslide plate, the two vertical plates are respectively located in the two through grooves, and a baffle is installed at the end face of the through groove away from the belt conveying mechanism.

[0010] In the above technical solution, preferably, a pushing groove is formed in the middle end of the sliding plate, the pushing mechanism includes four synchronous wheels, the four synchronous wheels are respectively rotatably installed at four end corners of the inner wall of the fixed frame plate, a synchronous belt is connected to the outer surfaces of the four synchronous wheels, a positioning block is fixedly installed on the surface of the synchronous belt, a pushing plate is installed at the top of the positioning block, the surface of the pushing plate is movably located in the pushing groove, a cross plate is movably installed in the fixed frame plate, the cross plate is parallel to the synchronous belt, a linear groove is formed on the surface of the cross plate, a second convex column is installed at the end of the positioning block, the surface of the second convex column is slidably installed in the linear groove, third convex columns are arranged at both ends of the cross plate, the third convex columns are slidably installed in the chute on the inner wall of the fixed frame plate, and a stepping motor is installed at the front end of the fixed frame plate, and the output end of the stepping motor is connected to one of the synchronous wheels.

The vertical plate plays a role in lifting the pulp molding products, reducing the contact area between the bottom of the pulp molding products and the landslide plate, which helps to stably convey the pulp molding products.

[0015] By setting up a pushing mechanism, the four synchronous wheels and the synchronous belt work together. With the limiting effect of the straight groove on the second convex column, it can ensure that the positioning block and the pushing plate move in a rectangular shape. The synchronous belt has high transmission accuracy and strong stability, and can accurately control the moving position of the pushing plate in the pushing groove, realizing the conveying of the pulp molding products, ensuring the accuracy of the distance and force of each push of the pulp molding products, and improving the consistency and stability of production.

[0023] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0025] As Figure 1 - Figure 6 Shown is a quantitative conveying device for pulp molding products, including a belt conveyor mechanism 1 and a suspension conveyor line 2. The suspension conveyor line 2 is arranged on the side of the belt conveyor mechanism 1. A fixed frame plate 18 is arranged at the front end of the belt conveyor mechanism 1. A slide plate 19 is installed on the top of the fixed frame plate 18. A pushing mechanism 21 is arranged inside the fixed frame plate 18. A plurality of suspension rods 3 are evenly installed inside the suspension conveyor line 2. A material supporting mechanism 4 is fixedly installed at the bottom end of the suspension rod 3. The belt conveyor mechanism 1 transports the pulp molding products to the surface of the slide plate 19. The pushing mechanism 21 pushes the pulp molding products on the surface of the slide plate 19 to the surface of the material supporting mechanism 4. By setting the material supporting mechanism 4 and the pushing mechanism 21, the pushing mechanism 21 can accurately control the moving position of the pushing plate 25 in the pushing groove 20, realizing the conveying work of the pulp molding products, so that the pulp molding products can accurately fall on the surface of the material supporting mechanism 4. When the material supporting mechanism 4 moves to a position corresponding to the fixed frame plate 18, the sliding column 15 can move to the highest position of the path groove 17, making the landslide plate 8 present an inclined state, providing guarantee for the smooth transition of the pulp molding products from the belt conveyor mechanism 1 to the material supporting mechanism 4. Then, during the forward movement of the material supporting mechanism 4 along with the suspension conveyor line 2, the landslide plate 8 gradually returns to the initial state, and the height of the vertical plate 12 is gradually higher than that of the landslide plate 8. The vertical plate 12 plays a role in supporting the pulp molding products, providing help for the subsequent drying link, being able to accelerate heat transfer and improve the drying speed of the pulp molding products.

[0026] A mating plate 16 is fixedly installed on the surface of the belt conveying mechanism 1 close to the hanging conveying line 2. A path groove 17 is formed on the surface of the mating plate 16. The path groove 17 cooperates with the material supporting mechanism 4. The path groove 17 provides an accurate movement path guidance for the material supporting mechanism 4 when receiving the pulp molded products. When the material supporting mechanism 4 moves to the vicinity of the fixed frame plate 18 along with the hanging conveying line 2 to receive the pulp molded products, it can travel along the track of the path groove 17, ensuring that the material supporting mechanism 4 is accurately in the appropriate position to receive the pulp molded products pushed from the belt conveying mechanism 1, avoiding problems such as inaccurate reception and dropping of the pulp molded products due to position deviation, and making the transition of the pulp molded products from the belt conveying mechanism 1 to the material supporting mechanism 4 smoother and more reliable.

[0027] The path groove 17 is arranged in an inclined shape, and the horizontal height in the middle of the path groove 17 is higher than the horizontal heights on both sides. The middle part of the path groove 17 corresponds to the fixed frame plate 18. The design with a higher middle part can enable the material supporting mechanism 4 to adjust its height when passing near the fixed frame plate 18, so that the material supporting mechanism 4 and the pulp molded products on the sliding plate 19 are in an appropriate height difference and position relationship, facilitating the pushing mechanism 21 to smoothly push the pulp molded products onto the material supporting mechanism 4, avoiding problems such as unsmooth pushing and blockage of the pulp molded products due to unreasonable height difference or position deviation, and ensuring the smoothness of the pulp molded product conveying process.

[0028] The material supporting mechanism 4 includes a fixing plate 5. The fixing plate 5 is fixedly connected to the hanging rod 3. Convex blocks 6 are installed at two end corners of the fixing plate 5 away from the belt conveying mechanism 1. An activity groove 7 is formed on the surface of the convex block 6. A landslide plate 8 is arranged above the fixing plate 5. First convex columns 9 are installed on both sides of the end face of the landslide plate 8 away from the belt conveying mechanism 1. The surface of the first convex column 9 is slidably installed in the activity groove 7. A rectangular groove 13 is formed in the middle of the other end of the landslide plate 8. A rectangular block 14 is installed in the rectangular groove 13 through a rotating shaft. A sliding column 15 is installed at the end of the rectangular block 14. The sliding column 15 is slidably installed in the path groove 17. When the material supporting mechanism 4 moves to the position corresponding to the fixed frame plate 18 along with the hanging conveying line 2, the sliding column 15 accurately moves to the highest point of the path groove 17, making the landslide plate 8 present an inclined state. This accurate position correspondence and inclined state design provide a strong guarantee for the smooth transition of the pulp molded products from the belt conveying mechanism 1 to the material supporting mechanism 4. Under the push of the pushing mechanism 21, the pulp molded products can naturally and smoothly fall on the inclined surface of the landslide plate 8, avoiding problems such as jamming, collision or dropping position deviation of the pulp molded products due to height difference and angle mismatch, and ensuring the continuity and stability of the pulp molded product conveying process.

[0029] Two vertical plates 12 are symmetrically installed on the surface of the fixed plate 5. Two through grooves 10 are symmetrically formed on the surface of the landslide plate 8. The two vertical plates 12 are respectively located in the two through grooves 10. A baffle 11 is installed at the end face of the through groove 10 away from the belt conveying mechanism 1. The vertical plate 12 is located inside the through groove 10, which can play an accurate limiting and guiding role in the movement of the landslide plate 8. This design further ensures that the landslide plate 8 can only slide along the direction defined by the vertical plate 12, effectively avoiding the situation of shaking or deviation of the landslide plate 8, and then ensuring the stability of the receiving and conveying process of the pulp molded products. When one end of the landslide plate 8 is lifted, the height of the surface of the landslide plate 8 is higher than that of the vertical plate 12. At this time, after the pulp molded product falls onto the surface of the landslide plate 8, it will move towards the inclined bottom end of the landslide plate 8 under the action of gravity. During this process, the baffle 11 plays a role in blocking the pulp molded product to prevent the pulp molded product from accidentally sliding off the end of the landslide plate 8. During the forward movement of the material supporting mechanism 4 along the suspension conveying line 2, the landslide plate 8 will gradually return to its initial state. At this time, the height of the vertical plate 12 is gradually higher than that of the landslide plate 8, and the vertical plate 12 plays a role in lifting the pulp molded product, which can effectively reduce the contact area between the bottom of the pulp molded product and the landslide plate 8. This not only helps the stable conveying of the pulp molded product, but also speeds up the heat transfer in the subsequent drying process, thereby improving the drying speed of the pulp molded product.

[0030] A push groove 20 is provided at the middle end of the slide plate 19, and the push mechanism 21 includes four synchronous wheels 22, which are rotatably mounted at the four end corners of the inner wall of the fixed frame plate 18 respectively, and the outer surfaces of the four synchronous wheels 22 are connected with a synchronous belt 23, and a positioning block 24 is fixedly mounted on the surface of the synchronous belt 23, and a push plate 25 is installed on the top of the positioning block 24, and the surface of the push plate 25 is movably located in the push groove 20, and a transverse plate 27 is movably installed inside the fixed frame plate 18, and the transverse plate 27 is parallel to the synchronous belt 23, and a linear groove 28 is provided on the surface of the transverse plate 27, and a second boss 26 is installed at the end of the positioning block 24, and the surface of the second boss 26 is slidably mounted in the linear groove 28, and third bosses 29 are provided at both ends of the transverse plate 27, and the third boss 29 is slidably mounted in the slide groove on the inner wall of the fixed frame plate 18, and a stepping motor 30 is installed at the front end of the fixed frame plate 18, and the output end of the stepping motor 30 is connected to one of them. The push mechanism 21 works together through four synchronous wheels 22 and the synchronous belt 23, and under the limiting effect of the straight groove 28 on the second protrusion 26, it can ensure that the positioning block 24 and the push plate 25 connected thereto make a rectangular movement. The synchronous belt 23 transmission has high precision and stability, and can accurately control the moving position of the push plate 25 in the push groove 20, ensuring that the distance and force of each push of the pulp molded product are relatively accurate, thereby realizing the transportation of the pulp molded product and improving the consistency and stability of production. Driven by the synchronous belt 23, the second protrusion 26 at the end of the positioning block 24 slides in the straight groove 28 of the cross plate 27, further guiding and limiting the movement of the positioning block 24, making the movement of the push plate 25 more stable and accurate, avoiding deviation or shaking, and effectively preventing the pulp molded product from falling or position deviation due to unstable pushing during the pushing process of the pulp molded product.

[0031] A limit plate 32 is provided at the front end of the slide plate 19, and the limit plate 32 is fixedly connected to the fixed frame plate 18. The limit plate 32 can clearly define the boundary where the pulp molded product is pushed on the slide plate 19, prevent the pulp molded product from detaching from the slide plate 19 due to excessive conveying by the belt conveyor mechanism 1, and improve the accuracy and stability of conveying the pulp molded product.

[0032] The end of the slide plate 19 close to the supporting mechanism 4 protrudes from the fixed frame plate 18, and an arc surface 31 is provided at its end. The arc surface 31 at the end plays a good guiding role. When the pulp molded product is pushed to the end of the slide plate 19, the arc surface 31 can guide the pulp molded product to transition naturally and smoothly to the landslide board 8. Compared with the right-angle or sharp end, the arc surface 31 avoids the hard collision between the pulp molded product and the end of the slide plate 19, reduces the risk of damage to the pulp molded product, and also makes the falling trajectory of the pulp molded product more controllable, ensuring that the pulp molded product falls accurately on the appropriate position of the landslide board 8.

[0033] Working principle: First, the belt conveying mechanism 1 transports the pulp molded products to the surface of the sliding plate 19. Then, the suspension conveying line 2 drives the material supporting mechanism 4 to move. When the material supporting mechanism 4 moves to the side of the fixed frame plate 18 along with the suspension conveying line 2, the sliding column 15 on the material supporting mechanism 4 travels along the trajectory of the path groove 17 on the surface of the mating plate 16 and accurately moves to the highest point of the path groove 17. At this time, the landslide plate 8 is in an inclined state, and the material supporting mechanism 4 is in a suitable position to receive the pulp molded products. Subsequently, the stepping motor 30 at the front end of the fixed frame plate 18 starts, driving one of the synchronous wheels 22 to rotate. The four synchronous wheels 22 and the synchronous belt 23 work together. Under the limiting action of the straight groove 28 on the second convex column 26, the positioning block 24 and the pushing plate 25 connected thereto perform a rectangular motion. The pushing plate 25 moves in the pushing groove 20, pushing the pulp molded products on the surface of the sliding plate 19 to the surface of the inclined landslide plate 8. Then, the pulp molded products move towards the lower end of the inclined landslide plate 8 under the action of their own gravity. During this process, the baffle 11 plays a role in blocking the pulp molded products to prevent them from accidentally slipping off the end of the landslide plate 8. Finally, during the process of the material supporting mechanism 4 moving forward along with the suspension conveying line 2, the landslide plate 8 gradually returns to its initial state. At this time, the height of the vertical plate 12 is gradually higher than that of the landslide plate 8, and the vertical plate 12 plays a role in lifting the pulp molded products, reducing the contact area between the bottom of the pulp molded products and the landslide plate 8, which is beneficial to accelerating heat transfer in the subsequent drying process and improving the drying speed.
