DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of 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 to the specific embodiments disclosed below.

[0018] like Figure 1 - Figure 6 The quantitative conveying equipment of pulp molded products shown in the figure comprises a belt conveying mechanism 1 and a suspension conveying line 2, the suspension conveying line 2 is arranged on the side of the belt conveying mechanism 1, a fixed frame plate 18 is arranged at the front end of the belt conveying 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 conveying line 2, a supporting mechanism 4 is fixedly installed at the bottom end of the suspension rod 3, the belt conveying mechanism 1 transfers the pulp molded products to the surface of the slide plate 19, and the pulp molded products on the surface of the slide plate 19 are pushed to the surface of the supporting mechanism 4 by the pushing mechanism 21, and by arranging the supporting mechanism 4 and the pushing mechanism 21, the pushing mechanism 21 can accurately control the pushing plate 2 In the moving position in the push groove 20, the pulp molded product is conveyed, so that the pulp molded product can accurately fall on the surface of the supporting mechanism 4. When the supporting mechanism 4 moves to the position corresponding to the fixed frame plate 18, the sliding column 15 can move to the highest point of the path groove 17, so that the slide plate 8 is inclined, which provides a guarantee for the smooth transition of the pulp molded product from the belt conveyor mechanism 1 to the supporting mechanism 4. Then, when the supporting mechanism 4 moves forward with the suspension conveyor line 2, the slide plate 8 gradually returns to the initial state, and the height of the vertical plate 12 gradually becomes higher than the slide plate 8. The vertical plate 12 plays a role in lifting the pulp molded product, which helps the subsequent drying process, accelerates the heat transfer, and improves the drying speed of the pulp molded product.

[0019] A matching plate 16 is fixedly installed on the surface of the belt conveyor mechanism 1 close to the suspension conveyor line 2, and a path groove 17 is opened on the surface of the matching plate 16. The path groove 17 cooperates with the supporting mechanism 4, and the path groove 17 provides precise movement path guidance for the supporting mechanism 4 when receiving pulp molded products. When the supporting mechanism 4 moves along the suspension conveyor line 2 to the vicinity of the fixed frame plate 18 to receive pulp molded products, it can move along the trajectory of the path groove 17 to ensure that the supporting mechanism 4 is accurately in a suitable position to receive the pulp molded products pushed from the belt conveyor mechanism 1, avoiding problems such as inaccurate reception and falling of pulp molded products due to position deviation, and making the transition of pulp molded products from the belt conveyor mechanism 1 to the supporting mechanism 4 smoother and more reliable.

[0020] The path groove 17 is set to be inclined, and the horizontal height of the middle part of the path groove 17 is higher than the horizontal height of its two sides. The middle part of the path groove 17 corresponds to the fixed frame plate 18. The higher design of the middle part can enable the supporting mechanism 4 to adjust the height of the supporting mechanism 4 when passing near the fixed frame plate 18, so that the supporting mechanism 4 and the pulp molded products on the slide plate 19 are in a suitable height difference and position relationship, which is convenient for the pushing mechanism 21 to smoothly push the pulp molded products to the supporting mechanism 4, avoiding problems such as poor pushing and blockage of pulp molded products due to unreasonable height difference or position deviation, and ensuring the smoothness of the pulp molded product conveying process.

[0021] The supporting mechanism 4 includes a fixed plate 5, which is fixedly connected to the suspension rod 3. The fixed plate 5 is provided with protrusions 6 at two end corners away from the belt conveyor mechanism 1. The surface of the protrusion 6 is provided with a movable groove 7. A slide plate 8 is provided above the fixed plate 5. The slide plate 8 is provided with first protrusions 9 on both sides of the end surface away from the belt conveyor mechanism 1. The surface of the first protrusion 9 is slidably installed in the movable groove 7. A rectangular groove 13 is provided in the middle of the other end of the slide plate 8. A rectangular block 14 is installed inside 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 supporting mechanism 4 As the suspension conveyor line 2 moves to a position corresponding to the fixed frame plate 18, the sliding column 15 moves precisely to the highest point of the path groove 17, so that the landslide plate 8 is inclined. This precise position correspondence and inclined state design provide a strong guarantee for the smooth transition of the pulp molded products from the belt conveyor mechanism 1 to the supporting mechanism 4. The pulp molded products can fall naturally and smoothly on the inclined landslide plate 8 surface under the push of the pushing mechanism 21, avoiding the pulp molded products from being stuck, colliding or falling position deviation caused by height difference, angle mismatch and other problems, and ensuring the continuity and stability of the pulp molded products conveying process.

[0022] Two vertical plates 12 are symmetrically installed on the surface of the fixed plate 5, and two through grooves 10 are symmetrically opened on the surface of the slide plate 8. The two vertical plates 12 are respectively located in the two through grooves 10, and the end surface of the through groove 10 away from the belt conveyor mechanism 1 is installed with a baffle 11. The vertical plates 12 are located inside the through groove 10, which can accurately limit and guide the movement of the slide plate 8. This design further ensures that the slide plate 8 can only slide along the direction limited by the vertical plates 12, effectively avoiding the shaking or deviation of the slide plate 8, thereby ensuring the stability of the pulp molded product receiving and conveying process. When one end of the slide plate 8 is lifted, the height of the surface of the slide plate 8 is higher than the vertical plate 12. At this time, the pulp molded product After falling onto the surface of the landslide board 8, it will move toward the inclined bottom end of the landslide board 8 under the action of gravity. During this process, the baffle 11 plays a shielding role for the pulp molded products to prevent the pulp molded products from accidentally sliding off the end of the landslide board 8. In the process of the supporting mechanism 4 moving forward with the suspension conveyor line 2, the landslide board 8 will gradually return to its initial state. At this time, the height of the vertical plate 12 is gradually higher than the landslide board 8. The vertical plate 12 plays a supporting role on the pulp molded products, which can effectively reduce the contact area between the bottom of the pulp molded products and the landslide board 8, which not only helps to stably transport the pulp molded products, but also accelerates heat transfer in the subsequent drying process, thereby increasing the drying speed of the pulp molded products.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] Working principle: First, the belt conveyor mechanism 1 transfers the pulp molded products to the surface of the slide plate 19, and then the suspension conveyor line 2 drives the supporting mechanism 4 to move. When the supporting mechanism 4 moves to the side of the fixed frame plate 18 along the suspension conveyor line 2, the sliding column 15 on the supporting mechanism 4 moves along the trajectory of the path groove 17 on the surface of the matching plate 16, and moves accurately to the highest point of the path groove 17. At this time, the slide plate 8 is inclined, and the supporting mechanism 4 is in a suitable position to receive the pulp molded products. Then the stepper motor 30 at the front end of the fixed frame plate 18 is started, driving one of the synchronous wheels 22 to rotate. The four synchronous wheels 22 and the synchronous belt 23 work together. Under the limiting effect of the straight groove 28 on the second convex column 26, the positioning block 24 and the positioning block connected thereto The push plate 25 makes a rectangular motion, and the push plate 25 moves in the push groove 20, pushing the pulp molded product on the surface of the slide plate 19 to the inclined surface of the landslide plate 8, and then the pulp molded product moves to the inclined bottom end of the landslide plate 8 under the action of its own gravity. In this process, the baffle 11 shields the pulp molded product to prevent the pulp molded product from accidentally sliding off the end of the landslide plate 8. Finally, as the supporting mechanism 4 moves forward with the suspension conveyor 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 the landslide plate 8. The vertical plate 12 lifts the pulp molded product and reduces the contact area between the bottom of the pulp molded product and the landslide plate 8, which is beneficial to accelerate heat transfer in the subsequent drying process and improve the drying speed.
