[0001] This utility model relates to the field of feeding equipment technology, specifically a sheet feeding device. Background Technology

[0002] In modern industrial production, sheet feeding devices are key equipment in the material transfer process and are widely used in various industries such as electronics, packaging, and building materials. Their main function is to stably and efficiently transport sheets from one place to another, ensuring the continuity and automation of the production process. Among them, the basic conveying architecture consisting of conveyor belts and storage trays has become a common design for sheet feeding devices due to its advantages of simple structure and controllable cost. However, in actual application, existing sheet feeding devices still have many technical problems that need to be solved.

[0003] The adhesion problem between the sheet and the conveyor belt is a core obstacle affecting feeding efficiency and quality. Due to the material characteristics of the sheet, surface static electricity, and friction generated when the conveyor belt comes into contact with the sheet, the sheet is very easy to adhere to the discharge end of the conveyor belt, resulting in sheet accumulation and poor feeding.

[0004] Therefore, we propose that there is an urgent need for a sheet feeding device. Utility Model Content

[0005] One of the technical problems to be solved by this application is to accelerate the separation of the sheet from the conveyor belt surface, thereby facilitating material unloading and storage.

[0006] To solve the above-mentioned technical problems, this application provides a sheet feeding device, including a conveyor belt for transporting sheet material and a storage tray. A sheet scraping frame is fixedly installed at the discharge end of the conveyor belt. An adjustable sheet vibration component is installed inside the sheet scraping frame. The sheet vibration component is configured to detach the sheet material from the conveyor belt through vibration. A sheet agitation component is provided at one end of the sheet scraping frame near the storage tray. The sheet agitation component is used to pick up the sheet material that is stuck to the conveyor belt.

[0007] In some embodiments, the plate scraping frame consists of two fixed plates and two connecting frames, the two connecting frames connecting the two fixed plates, and the fixed plates being fixedly connected to the conveyor belt.

[0008] In some embodiments, guide rods are symmetrically fixedly installed on the fixed plate, and a stabilizing frame is slidably sleeved on the guide rods.

[0009] In some embodiments, a top frame is provided above the plate scraping frame, and both ends of the top frame are fixedly connected to the stabilizing frame. A high-speed CCD camera is provided inside the top frame.

[0010] In some embodiments, the plate vibration assembly includes a sliding plate that is laterally slidably inserted into the stabilizer. A drive motor is fixedly installed inside the stabilizer, and a drive screw is fixedly installed at the output end of the drive motor. One end of the sliding plate is sleeved on the end of the drive screw.

[0011] In some embodiments, a stabilizing rod is fixedly installed at the other end of the sliding plate, a vibration block is fixedly installed at one end of the stabilizing rod, a support plate is fixedly installed on the stabilizing rod, and a vibration motor is symmetrically fixedly installed on the support plate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-8 This utility model provides a technical solution: a sheet feeding device, including a conveyor belt 1 for transporting sheet material and a storage tray 2. A sheet scraping frame 3 is fixedly installed at the discharge end of the conveyor belt 1. An adjustable sheet vibration component 4 is installed inside the sheet scraping frame 3. The sheet vibration component 4 is configured to cause the sheet material to detach from the adhesive state of the conveyor belt 1 through vibration. A sheet agitation component 5 is provided at one end of the sheet scraping frame 3 near the storage tray 2. The sheet agitation component 5 is used to pick up the sheet material that is stuck to the conveyor belt 1.

[0026] Example 2: As Figure 4 As shown, the sheet scraping frame 3 consists of two fixed plates 301 and two connecting frames 302. The two connecting frames 302 connect the two fixed plates 301. The fixed plates 301 are fixedly connected to the conveyor belt 1. It should be noted that the connecting frames 302 are fixedly installed on the two fixed plates 301 by welding, and the fixed plates 301 are installed on the discharge end of the conveyor belt 1 by appropriate screws or bolts.

[0027] like Figure 6As shown, guide rods 6 are symmetrically fixedly installed on the fixed plate 301. A stabilizing frame 7 is slidably sleeved on the guide rods 6. Adjusting cylinders 8 are fixedly installed at both ends of the stabilizing frame 7. Adjusting springs 9 are fixedly installed inside the adjusting cylinders 8. Adjusting conical rods 10 are fixedly installed at the output end of the adjusting springs 9. Positioning grooves 11 are evenly spaced on one side of the connecting frame 302 on the fixed plate 301. The adjusting conical rods 10 and the positioning grooves 11 are slidably engaged with each other. A top frame 12 is set above the plate scraping frame 3. The two ends of the bottom of the top frame 12 are fixedly connected to the stabilizing frame 7 respectively. A high-speed CCD camera 13 is set inside the top frame 12. It should be noted that by pulling the top frame 12, the stabilizing frames 7 at both ends of the bottom of the top frame 12 can be driven to rise. At this time, under the elastic deformation of the adjusting springs 9, the adjusting conical rods 10 and the positioning grooves 11 can be slidably engaged, which facilitates the plate vibration assembly 4 to vibrate plates of different thicknesses and accelerates the separation of the plates from the conveyor belt 1.

[0028] Example 3: As Figure 6 As shown, the plate vibration assembly 4 includes a sliding plate 401, which is laterally slidably inserted into a stabilizer 7. A drive motor 402 is fixedly installed inside the stabilizer 7, and a drive screw 403 is fixedly installed at the output end of the drive motor 402. One end of the sliding plate 401 is sleeved on the end of the drive screw 403, and a stabilizer rod 404 is fixedly installed at the other end of the sliding plate 401. A vibration block 405 is fixedly installed at one end of each stabilizer rod 404, and a support plate 406 is fixedly installed on the stabilizer rod 404. Vibration motors 407 are symmetrically fixedly installed on the support plate 406, and one end of the vibration motor 407 is fixedly connected to the vibration block 405. It should be noted that the drive... The drive motor 402 is a servo motor and is powered by an external power source (not shown in the figure). When the board passes under the top frame 12, the high-speed CCD camera 13 sends a signal to the programmable logic controller 14 on one side of the board scraping frame 3. At this time, the programmable logic controller 14 controls the drive motor 402 to drive the drive screw 403 to rotate. The rotation of the drive screw 403 enables the sliding plate 401 to move laterally. The vibration motor 407 is also powered by an external power source and, under the control of the programmable logic controller 14, enables the vibration block 405 to vibrate the side of the board, thereby accelerating the separation of the board from the conveyor belt 1.

[0029] Example 4: Figure 7As shown, the sheet material actuation assembly 5 includes a hub motor 501, and a lifting frame 502 is sleeved on the outside of the hub motor 501. Pressure sensors 503 are distributed inside one end of the lifting frame 502. It should be noted that the hub motor 501 is powered by an external power supply (not shown in the diagram). When one end of the sheet material is conveyed to the lifting frame 502 along the conveyor belt 1, the multiple pressure sensors 503 inside the lifting frame 502 can detect that the sheet material has moved above the lifting frame 502. At this time, the programmable logic controller 14 can control the hub motor 501 to start. The hub motor 501 rotates according to the set program, which can lift the sheet material, thereby facilitating the separation of the sheet material from the conveyor belt 1 and its fall into the storage tray 2.
