Description

Technical Field

[0001] This utility model belongs to the field of paper conveying technology, specifically, it relates to an automatic conveying device for defective paper. Background Technology

[0002] In the paper processing industry, defective paper is often transported and processed centrally using conveyor belts. Currently, traditional conveyor belt devices often have multiple feeding positions along the conveying path to meet the needs of multi-station feeding, but existing technologies lack effective feeding guidance and interference avoidance structures. When multiple feeding positions operate simultaneously or alternately, defective paper falling from different feeding ports is prone to colliding and piling with the raw materials originally being conveyed on the conveyor belt, causing cross-interference. Due to the lack of directional guiding components, the material is prone to deviating from the preset trajectory during the conveying process. Some lightweight waste paper may even bounce and scatter due to collisions, which not only leads to waste of raw materials but also affects the continuous operating efficiency of the conveyor belt and increases the workload of subsequent cleaning and sorting.

[0003] In view of this, this utility model is hereby proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An automatic conveying device for defective paper includes a conveyor belt body.

[0005] The conveyor belt body is equipped with several sealing covers to prevent waste paper from splashing. The sealing cover has a feeding port, and a baffle is rotatably installed at the bottom of the sealing cover. The baffle is used to block the feeding port. A baffle is installed on the baffle. When the baffle is separated from the feeding port, the baffle is in an inclined state. The inclined baffle cooperates with the sealing cover to guide the raw material on the conveyor belt body to be conveyed along one side, and does not interfere with the feeding position of the feeding port. A positioning shaft is installed at the rotation center of the cover, and the positioning shaft passes through the sealing cover. A knob is installed at the end of the positioning shaft, and the surface of the knob is knurled.

[0006] In a preferred embodiment of this utility model, the bottom of the sealing cover is integrally cast with a mounting ear, which fits against the outer frame of the conveyor belt body, and the mounting ear and the outer frame of the conveyor belt body are connected by bolts.

[0007] In a preferred embodiment of this utility model, a feed pipe is installed on the sealing cover, the feed pipe is vertically aligned with the feeding port, and a connecting flange is installed at the end of the feed pipe, with mounting holes provided on the connecting flange for easy connection.

[0008] In a preferred embodiment of this utility model, the sealing cover and the baffle are provided with through holes at corresponding positions, and a positioning rod is movably inserted into the through hole. A positioning ball is installed at the end of the positioning rod, and the diameter of the positioning ball is larger than the diameter of the positioning rod, and the positioning ball is placed above the through hole.

[0009] In a preferred embodiment of this utility model, a guide rod is installed inside the sealing cover. The guide rod is arc-shaped, and the center of curvature of the guide rod is the same as that of the positioning shaft. The guide rod and the baffle pass through each other. A positioning seat is installed at the end of the guide rod, and the positioning seat is installed on the inner wall of the sealing cover.

[0010] In a preferred embodiment of this utility model, a storage spring is sleeved on the guide rod, one end of the storage spring is clamped to the side wall of the positioning seat, and the other end of the storage spring is clamped to a push plate, the push plate and the baffle are connected to each other.

[0011] Compared with the prior art, the present invention has the following advantages: This utility model features a baffle and a shield. When the rotating baffle opens the discharge port, the linked baffle rotates synchronously with the positioning shaft, precisely moving to the inclined position. At this time, the baffle guides the falling defective paper towards one side of the conveyor belt, achieving directional flow guidance. Furthermore, by utilizing the preset inclination angle and spatial position, it cleverly avoids the material falling path at the discharge port, ensuring that the feeding process and the conveying trajectory do not intersect. This not only guarantees the smoothness of material conveying but also simplifies operation through structural linkage, allowing a single action to simultaneously achieve multiple effects such as opening, guiding, and preventing interference, significantly improving the integrated efficiency of the device. The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0015] like Figures 1 to 4 As shown, an automatic conveying device for defective paper includes a conveyor belt body 1.

[0016] Several sealing covers 2 are installed on the conveyor belt body 1 to prevent waste paper from splashing; The sealing cover 2 has a feeding port 4. A baffle 10 is rotatably installed at the bottom of the sealing cover 2. The baffle 10 is used to block the feeding port 4. A baffle 7 is installed on the baffle 10. When the baffle 10 is separated from the feeding port 4, the baffle 7 is in an inclined state. The inclined baffle 7 cooperates with the sealing cover 2 to guide the raw material on the conveyor belt body 1 to be conveyed along one side, and does not interfere with the feeding position of the feeding port 4. A positioning shaft 8 is installed at the rotation center of the cover 10. The positioning shaft 8 passes through the sealing cover 2. A knob 9 is installed at the end of the positioning shaft 8, and the surface of the knob 9 is knurled. The knurled knob 9 is easy for the operator to grip and apply force, improving the convenience of rotation operation. The positioning shaft 8 provides stable support for the rotation of the cover 10 and the baffle 7.

[0017] like Figures 1 to 4 As shown in the specific embodiment, the bottom of the sealing cover 2 is integrally cast with a mounting ear 3. The mounting ear 3 fits snugly against the outer frame of the conveyor belt body 1, and the mounting ear 3 and the outer frame of the conveyor belt body 1 are connected by bolts. The integrally cast mounting ear 3 enhances the connection strength with the sealing cover 2, and the bolt connection ensures that the sealing cover 2 and the conveyor belt body 1 are installed firmly, facilitating disassembly and maintenance.

[0018] like Figures 1 to 4 As shown, furthermore, a feed pipe 5 is installed on the sealing cover 2, which is vertically aligned with the feeding port 4. A connecting flange 6 is installed at the end of the feed pipe 5, and the connecting flange 6 has mounting holes for easy connection. The vertical alignment of the feed pipe 5 with the feeding port 4 ensures a smooth material conveying path, while the connecting flange 6 facilitates connection with external pipelines, improving the versatility and connection efficiency of the device.

[0019] like Figures 1 to 4As shown, the sealing cover 2 and the baffle 10 have corresponding through holes 12, and a positioning rod 11 is movably inserted into the through hole 12. A positioning ball 17 is installed at the end of the positioning rod 11, and the diameter of the positioning ball 17 is larger than the diameter of the positioning rod 11. The positioning ball 17 is positioned above the through hole 12. The cooperation between the positioning rod 11 and the through hole 12 can fix the position of the baffle 10 and the baffle 7. The positioning ball 17 can prevent the positioning rod 11 from falling out of the through hole 12, ensuring the reliability of positioning.

[0020] like Figures 1 to 4 As shown, a guide rod 13 is installed inside the sealing cover 2. The guide rod 13 is arc-shaped, and its center of curvature is the same as that of the positioning shaft 8. The guide rod 13 passes through the baffle 7. A positioning seat 14 is installed at the end of the guide rod 13. The positioning seat 14 is installed on the inner wall of the sealing cover 2. A storage spring 16 is sleeved on the guide rod 13. One end of the storage spring 16 is engaged with the side wall of the positioning seat 14, and the other end of the storage spring 16 is engaged with a push plate 15. The push plate 15 is connected to the baffle 7. The arc-shaped guide rod 13 provides a stable trajectory for the rotation of the baffle 7. The storage spring 16 can drive the baffle 7 and the shield 10 to reset through the push plate 15, ensuring that the shield 10 effectively blocks the feeding port 4. The positioning seat 14 provides stable support for the guide rod 13 and the storage spring 16.

[0021] The implementation principle of the automatic conveying device for defective paper in this embodiment is as follows: When using this device, firstly, each sealing cover 2 is securely installed on the outer frame of the conveyor belt body 1 using mounting ears 3. The connection is ensured by tightening bolts, and each sealing cover 2 is adapted to its corresponding feeding position. Next, the external pipe for conveying defective paper is connected to the feed pipe 5 using connecting flange 6. The defective paper raw material enters the interior of the sealing cover 2 through the feed pipe 5 and the feeding port 4, and falls onto the conveyor belt body 1.

[0022] In the initial state, under the action of the storage spring 16, the baffle 10 tightly seals the feeding port 4 through the transmission of the push plate 15 and the baffle 7. At this time, there is no need to insert the positioning rod 11 into the through hole 12. The reliable seal can be achieved by relying solely on the elastic force of the storage spring, preventing the raw material from splashing when no conveying operation is performed.

[0023] When a feeding position needs to be activated, the operator rotates the knurled knob 9, which drives the positioning shaft 8 and the baffle 10 to rotate. At this time, the baffle 10 separates from the feeding port 4. During the rotation of the baffle 10, the baffle 7 moves along the arc-shaped guide rod 13, and the push plate 15 compresses the storage spring 16 to store the elastic force. After the baffle 7 rotates to the tilted state, the positioning rod 11 is inserted into the through hole 12 to complete the positioning. At this time, the tilt angle is maintained under the action of the storage spring 16. The tilted baffle 7 and the sealing cover 2 cooperate with each other to guide the raw material on the conveyor belt body 1, so that it is conveyed along one side and will not interfere with the feeding position of the feeding port 4, ensuring the smooth conveying of raw materials.

[0024] When a particular feeding position is not needed, first pull out the positioning rod 11, then rotate the positioning shaft 8 using the knob 9. This rotates the cover 10 until it is flush with the feeding port 4, tightly sealing the feeding port 4 and preventing raw materials from entering the conveyor belt body 1 at that feeding position. In this way, the activation and deactivation of each feeding position can be flexibly controlled according to actual production needs, achieving orderly conveying and diversion of defective paper. At the same time, the sealing cover 2 effectively prevents waste paper from splashing during conveying, ensuring a clean and safe production environment.
