Technical Field

[0001] The invention relates to the technical field of powder conveying, and in particular to a crystal stone plate calendering powder conveying device. Background Art

[0002] Powdered wood board is a board made of wood fiber material and adhesive. It uses a hot pressing process to bond wood fiber material under high temperature and high pressure. Compared with traditional wood boards, powdered wood boards are waterproof, moisture-proof, wear-resistant, and anti-corrosive. They are also light in weight, have good rigidity, are not easy to deform, are easy to process, and can also be made into composite boards.

[0003] The production process of powder wood board mainly includes the following steps: first, the wood fiber material is converted into powder, then a binder is added, the mixture is stirred evenly and pressed into shape. During the processing, pigments or other processing agents can be added to give it different characteristics and appearance effects.

[0004] Regarding the above technical problems, a Chinese patent with announcement number CN105346999B discloses a dry powder conveyor, which belongs to the field of dry powder processing equipment, including an annular conveying pipeline and a conveying mechanism arranged in the conveying pipeline; a discharge port is arranged on the upper side wall of the conveying pipeline, and a feed port is arranged on the lower side wall; the conveying mechanism includes a carrier, a conveying slide rail and a drive motor, the conveying slide rail is annular and runs through the conveying pipeline, the carrier is connected to the conveying slide rail through a conveying platform, the conveying platform is connected to the drive motor by transmission, the drive motor is connected to the controller, and the conveying pipeline is provided with a dumping mechanism for leading the powder in the carrier out of the discharge port near the discharge port. Although this patent realizes the automatic conveying of powder, it can only convey one kind of powder, and it is impossible to quantitatively convey multiple powders, and it is impossible to meet the requirements of conveying multiple powders to the destination according to the required ratio. In addition, when unloading, an additional dumping mechanism needs to be added to realize the unloading function, which increases the manufacturing cost and maintenance cost.

[0005] As disclosed in a Chinese patent with the publication number CN102837968B, a powder conveying system is provided. The system includes a feeding hopper, a gear pump, a mixer, a conveying pipeline, an aggregate hopper, and a dust collector. The feeding hopper, the gear pump, the mixer, the conveying pipeline, and the aggregate hopper are connected in sequence. Among them, the feeding hopper is connected to the feeding end of the gear pump. The gear pump includes a housing, a meshing gear set, and a power source. The meshing gear set is arranged inside the housing and includes two meshing gears. Both gears are rotatably connected to the housing. When the meshing gear set rotates, two adjacent teeth on the same gear can cyclically cooperate with the housing to form a powder conveying cavity. The mixer is provided with a compressed gas inlet. The dust collector is arranged on the top of the aggregate hopper. If this patent needs to convey multiple powders, an additional feeding mechanism is required for feeding, which not only reduces the powder conveying efficiency but also increases the production cost.

The spring is located above the baffle plate. A conical block is installed at the upper end of the baffle plate.

[0015] Preferably, several notches are formed in the upper part of the circumferential surface of the receiving pipe.

[0016] Preferably, one end of the powder container away from the machine frame is provided with a first inclined portion that slopes outward.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) By providing several silos for placing different types of powders respectively, by providing an installation mechanism for installing the powder container, using the circulating conveying mechanism to drive the powder container to move sequentially below several silos, and through the cooperation of the installation mechanism with the first guide rail and the second guide rail, the receiving pipe moves upward and communicates with the corresponding silo, realizing automatic feeding of the powder.

[0020] (3) In the present invention, the receiving pipe moves upward and passes through the discharge port, and then pushes the baffle plate upward, so that the powder materials in the silo enter the powder container through the notch. At this time, the sealing cover is in close contact with the powder container under the action of gravity and the reaction force of the receiving pipe, avoiding the diffusion of powder materials into the environment. When the powder container performs a flipping action, the sealing cover is separated from the powder container under its own weight, facilitating the rapid completion of dumping of the powder in the container, and the discharging and receiving of the powder container can be carried out synchronously, improving the efficiency of the entire powder material transportation process.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to Figures 1-10 , this embodiment provides a calendering powder conveying device for spar plates, which includes a circulating conveying mechanism 2 installed above the frame 1. The circulating conveying mechanism 2 is drivingly connected to four uniformly distributed mounting mechanisms 3. A powder container 4 is rotatably connected inside each mounting mechanism 3. A sealing cover 5 is rotatably connected to the inner side of the upper end of the powder container 4. Taking the direction close to the frame 1 as the inside, a receiving pipe 11 is installed at the upper end of the sealing cover 5. A plurality of notches 111 are opened on the upper part of the circumferential surface of the receiving pipe 11. The frame 1 has a runway-shaped structure. The outer surface of the frame 1 is fixedly sleeved with a second guide rail 7 and a first guide rail 6 in sequence from top to bottom. The mounting mechanism 3 is drivingly connected to both the second guide rail 7 and the first guide rail 6. A storage bin 8 is arranged on one side of the frame 1. There are three storage bins 8, and the three storage bins 8 are arranged side by side and are parallel to the axis of the frame 1. An upper and lower through discharge port 9 is opened at the lower end of each storage bin 8. A baffle plate 10 that can move up and down along the axis of the discharge port 9 is arranged on the lower wall of the inner cavity of each storage bin 8. It should be noted that the number of storage bins 8 is determined according to actual production requirements. In this embodiment, the three storage bins 8 are respectively used to store different powders.

[0025] Among them, the cyclic conveying mechanism 2 is used to drive several installation mechanisms 3 to move sequentially to directly below several discharge ports 9. Specifically: The cyclic conveying mechanism 2 includes two sprockets respectively movably connected to the upper end surface of the frame 1. A chain belt is commonly sleeved between the two sprockets. It also includes a motor installed inside the frame 1, and the output end of the motor is coaxially fixedly connected to one of the sprockets; the chain belt is composed of several chain links, and through holes are provided on each chain link. When the motor is started, the output end of the motor drives one of the sprockets to rotate, this sprocket drives the chain belt to rotate, and the chain belt drives the installation mechanism 3 to rotate.

[0026] When an installation mechanism 3 moves to directly below a bin 8, the powder container 4 inside the installation mechanism 3 moves upward in the vertical direction, so that the material receiving pipe 11 is communicated with the corresponding bin 8, and the powder in the bin 8 is conveyed into the powder container 4.

[0027] Specifically, the first guide rail 6 is composed of a first horizontal section 61, a first ascending and resetting section 62, and a descending and resetting section 63. There are three first ascending and resetting sections 62, and several first ascending and resetting sections 62 are respectively located directly below the three discharge ports 9. The first ascending and resetting section 62 has an upward convex structure, and the descending and resetting section 63 has a downward convex structure; the second guide rail 7 is composed of a second horizontal section 71 and a second ascending and resetting section 72. The number of the second ascending and resetting sections 72 is the same as that of the first ascending and resetting sections 62, and several second ascending and resetting sections 72 are respectively located directly above the several first ascending and resetting sections 62. The distance between the second ascending and resetting section 72 and the first ascending and resetting section 62 is equal to the distance between the second horizontal section 71 and the first horizontal section 61; the installation mechanism 3 includes a vertically arranged first U-shaped frame 31. The first U-shaped frame 31 is fixedly connected to a link. Vertical sliding grooves 32 are opened at both ends of the first U-shaped frame 31. A second U-shaped frame 33 is slidably connected between the two vertical sliding grooves 32. A vertical rod 34 is installed at the lower end of the second U-shaped frame 33. The lower end of the vertical rod 34 movably passes through the first U-shaped frame 31 and a second guide rod 35 is installed. The second guide rod 35 is perpendicular to the vertical rod 34. The second guide rod 35 is slidably connected to the second guide rail 7; the powder container 4 is located inside the second U-shaped frame 33, and the powder container 4 is rotatably connected to the second U-shaped frame 33. A connecting rod 41 is rotatably connected to one end of the powder container 4 away from the machine frame 1. The other end of the connecting rod 41 is rotatably connected to a first guide rod 42. The first guide rod 42 is slidably connected to the first guide rail 6. When the first guide rod 42 moves to the first ascending and resetting section 62, the second guide rod 35 synchronously moves to the corresponding second ascending and resetting section 72. When the second guide rod 35 moves upward along the second ascending and resetting section 72, the second guide rod 35 drives the second U-shaped frame 33 to move upward through the vertical rod 34. The second U-shaped frame 33 drives the powder container 4 to move upward. At the same time, the first guide rod 42 also drives the powder container 4 to move upward through the connecting rod 41, so that the powder container 4 is evenly stressed and remains in a vertical state. The powder container 4 drives the material receiving pipe 11 to move upward through the sealing cover 5, so that the material receiving pipe 11 passes through the corresponding discharge port 9 and pushes up the corresponding baffle 10. The powder in the corresponding bin 8 moves closer to the material receiving pipe 11 under the action of gravity. Part of the powder enters the powder container 4 through the notch 111. During the powder receiving process, the output end of the motor is in a stopped state. At this time, the amount of powder entering the powder container 4 can be controlled by controlling the stop time of the motor. After the powder is received, the motor is started again, so that the second guide rod 35 moves downward and resets along the second ascending and resetting section 72, that is, drives the material receiving pipe 11 away from the bin 8. At this time, the baffle 10 is reset downward under the action of its own weight and the pressure of the internal powder, and reseals the discharge port 9.

[0028] In practical applications, since both the ascending section and the descending section in the second ascending and resetting section 72 have a certain inclination, the material receiving pipe 11 does not move vertically upward or downward, but has a certain displacement in the horizontal direction. To ensure that the material receiving pipe 11 can be connected to the material bin 8, in this embodiment, the discharge port 9 has a trumpet-shaped structure that is thicker at the bottom and thinner at the top, and the diameter of the upper end of the discharge port 9 is larger than the diameter of the material receiving pipe 11. Through the trumpet-shaped structural design of the discharge port 9, when the material receiving pipe 11 moves closer to or farther away from the discharge port 9, a certain horizontal displacement can be carried out. At the same time, the diameter of the discharge port 9 is larger than the diameter of the material receiving pipe 11, which further ensures that the material receiving pipe 11 can carry out a certain degree of horizontal displacement within the discharge port 9.

[0029] On the basis of the above solution, to prevent the powder from flowing out through the gap between the discharge port 9 and the material receiving pipe 11, in this embodiment, a rubber ring 91 is fixedly sleeved on the upper part of the inner wall of the discharge port 9. The gap between the discharge port 9 and the material receiving pipe 11 is blocked by the rubber ring 91, and the material receiving pipe 11 can squeeze the rubber ring 91 when performing horizontal displacement. By utilizing the deformable characteristic of the rubber ring 91, the space requirement for the material receiving pipe 11 to perform horizontal displacement within the discharge port 9 is met.

[0030] Specifically, the height of the material receiving pipe 11 is greater than the thickness of the discharge port 9, and the height of the first ascending and resetting section 62 is greater than the height of the material receiving pipe 11. Ensure that the material receiving pipe 11 can be completely connected to the material bin 8.

[0031] Specifically, four sliding rods 101 are movably inserted through the upper end of the baffle plate 10. The lower ends of the sliding rods 101 are fixedly connected to the lower wall of the inner cavity of the material bin 8. A spring 102 is sleeved on the circumferential surface of the sliding rods 101, and the spring 102 is located above the baffle plate 10. Through the guiding action of the sliding rods 101, the baffle plate 10 can only move along the axial direction of the sliding rods 101. When the baffle plate 10 moves upward, the spring 102 is compressed and deformed, and thrust is accumulated. When the material receiving pipe 11 moves downward, the spring 102 pushes the baffle plate 10 to move downward synchronously with the material receiving pipe 11, reducing the amount of powder flowing out through the discharge port 9.

[0032] On the basis of the above solution, to reduce the pressure of the powder on the baffle plate 10 when the baffle plate 10 moves upward, in this embodiment, a conical block 103 is installed at the upper end of the baffle plate 10. The powder is guided to the periphery of the baffle plate 10 by the arc surface of the conical block 103, reducing the pressure of the powder on the baffle plate 10 and facilitating the material receiving pipe 11 to jack up the baffle plate 10.

[0033] After the powder container 4 receives all the powder in the bins 8, the cyclic conveying mechanism 2 continues to drive the powder container 4 to move to the discharging area. At the same time, the powder container 4 flips towards the side away from the frame 1 to dump all the powder inside it into the discharging area. When the powder container 4 moves to the discharging area, the first guide rod 42 just enters the descending and resetting section 63, while the second guide rod 35 is located at the second horizontal section 71. The first guide rod 42 descends along the descending and resetting section 63 and drives the powder container 4 to complete the flipping action.

[0034] In practical applications, since there is a large amount of sheet powder in the powder container 4, in order to improve the discharging efficiency, in this embodiment, the end of the powder container 4 away from the frame 1 is provided with a first inclined portion 43 that slopes outward, the upper end of the powder container 4 is provided with a second inclined portion 45 that is higher inside and lower outside, and the upper part of the first inclined portion 43 is provided with a discharge opening 44 that protrudes outward. When the first guide rod 42 descends to the lowest point along the descending and resetting section 63, the powder container 4 just flips by ninety degrees. Due to the design of the second inclined portion 45, a certain distance is generated between the opening area of the powder container 4 and the sealing cover 5, and the powder flows out along the inclined surface of the first inclined portion 43.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features.
