Description

Technical Field

[0001] This utility model relates to the field of quality inspection machine technology, specifically an automatic feeding device for quality inspection machines. Background Technology

[0002] Inspection machines are generally used to check the printing quality of printed materials. Before inspection, the stacked printed materials need to be laid out one by one for inspection. The patent document with announcement number CN217996139U describes a stable feeding mechanism for a green printed material inspection machine. This mechanism allows only one printed material to pass through at a time by adjusting the height of the slit. The conveyor belt carries the bottom printed material out of the material trough each time, so that the stacked printed materials can be laid out one by one for inspection. However, after the printed materials in the material trough have been inspected, the handle needs to be lifted while the printed materials are neatly stacked in the material trough. The replenishment speed is slow, which affects the efficiency of the printing quality inspection machine.

[0003] Based on this, an automatic feeding device for quality inspection machines is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for a quality inspection machine to solve the problem of slow replenishment speed of printed materials in the material tank in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic feeding device for a quality inspection machine includes a fixed frame, on which multiple conveyor rollers are rotatably connected. A conveyor belt is provided around each conveyor roller, and the conveyor belt has ventilation gaps. A negative pressure structure is provided on the fixed frame. A first fixed plate is connected to the fixed frame, and a feeding trough is slidably connected to the first fixed plate. The feeding trough has a paper output limiting structure. The fixed frame has a moving structure that drives the feeding trough to slide on the fixed frame. Two material support plates for pre-feeding are symmetrically provided on the first fixed plate. The material support plates are slidably connected to the first fixed plate via a reset structure. A check structure is symmetrically provided on the feeding trough to retain printed materials on the material support plates within the feeding trough.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-7As shown, an automatic feeding device for a quality inspection machine includes a fixed frame 101, a plurality of conveyor rollers 102 rotatably connected to the fixed frame 101, a conveyor belt 103 provided outside the conveyor rollers 102, a ventilation gap 203 provided on the conveyor belt 103, a negative pressure structure provided on the fixed frame 101, a first fixed plate 104 connected to the fixed frame 101, a feeding trough 105 slidably connected to the first fixed plate 104, a paper output limiting structure provided on the feeding trough 105, a moving structure provided on the fixed frame 101 to drive the feeding trough 105 to slide on the fixed frame 101, two material support plates 106 symmetrically provided on the first fixed plate 104 for pre-feeding, the material support plates 106 slidably connected to the first fixed plate 104 through a reset structure, and check structures symmetrically provided on the feeding trough 105 to retain the printed matter on the material support plates 106 in the feeding trough 105.

[0027] In this embodiment, the negative pressure structure improves the adhesion of printed materials in direct contact with the conveyor belt 103. The conveyor belt 103 carries away the bottom printed material from the stack. The paper output limiting structure allows only one printed material to leave the feeding trough 105 at a time. Printed materials to be inspected are pre-stacked on the material tray 106. The moving structure drives the feeding trough 105 to move, so that the material tray 106 enters the feeding trough 105. The check structure keeps the stacked printed materials on the material tray 106 in the feeding trough 105. The reset structure drives the material tray 106 to leave the feeding trough 105, so that the stacked printed materials fall onto the conveyor belt 103, achieving rapid feeding.

[0028] In one embodiment, such as Figure 1 and Figure 7 As shown, the negative pressure mechanism includes a negative pressure box 201 connected to the fixed frame 101. The negative pressure box 201 is connected to the negative pressure pipe 202. The open side of the negative pressure box 201 is in contact with the conveyor belt 103. There is negative pressure in the ventilated gap 203 within the coverage area of ​​the negative pressure box 201, which will attract the printed matter that is in direct contact with the conveyor belt 103 and make it move synchronously with the conveyor belt 103.

[0029] In one embodiment, such as Figure 6 and Figure 7As shown, the paper output limiting structure includes a paper output port 301 opened on the feeding trough 105. Two first fixing blocks 304 are symmetrically connected on the feeding trough 105. A guide post 303 is slidably connected through the first fixing block 304. The guide post 303 is connected to a baffle plate 302. The position of the baffle plate 302 corresponds to the position of the paper output port 301. A first lead screw 306 is rotatably connected to the feeding trough 105. A first motor 307 is connected to the feeding trough 105. The output end of the first motor 307 is connected to the first lead screw 306. A connecting plate 305 is connected to the baffle plate 302. The first lead screw 306 is threaded through and connected to the connecting plate 305. The first motor 307 drives the first lead screw 306 to rotate. The connecting plate 305 moves on the first lead screw 306. The connecting plate 305 drives the baffle plate 302 to move up and down, thereby limiting the height of the paper output port 301.

[0030] In one embodiment, such as Figure 3 As shown, the movable structure includes a telescopic rod 601 connected to the first fixed plate 104, a third fixed plate 602 connected to the feeding trough 105, the output end of the telescopic rod 601 connected to the third fixed plate 602, and the telescopic rod 601 extends and retracts to drive the feeding trough 105 to slide on the first fixed plate 104.

[0031] In one embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the reset structure includes a second fixing block 401 symmetrically connected to the first fixing plate 104. A guide rod 402 is slidably connected through the second fixing block 401. The guide rod 402 is connected to the material support plate 106. A rack 403 is connected to the material support plate 106. A second motor 405 is connected to the first fixing plate 104. The output end of the second motor 405 is connected to a gear 404. The gear 404 meshes with the rack 403. A snap-fit ​​structure is provided between the feeding groove 105 and the material support plate 106. The snap-fit ​​structure includes a telescopic groove 701 provided on the feeding groove 105. A telescopic block 702 is slidably provided in the telescopic groove 701. The telescopic block 702 and the telescopic groove 701 are connected... A spring 703 is provided, and a notch 704 is provided on the material support plate 106 at the position corresponding to the telescopic block 702. The moving structure drives the feeding trough 105 to slide, so that the material support plate 106 enters the feeding trough 105. The telescopic block 702 and the spring 703 cooperate to lock the notch 704, connecting the material support plate 106 and the feeding trough 105 together. The moving structure drives the feeding trough 105 to retract, and the feeding trough 105 moves synchronously with the material support plate 106, so that the stacked printed materials are located directly above the conveyor belt 103. The second motor 405 drives the rack 403 through the gear 404, so that the material support plate 106 separates from the feeding trough 105 and returns to the initial position, waiting for pre-loading.

[0032] In one embodiment, such as Figure 2 and Figure 3As shown, the check valve structure includes a second fixed plate 501 connected to the outside of the feeding trough 105. A check valve 107 is rotatably connected to the second fixed plate 501. A worm gear 502 is coaxially connected to the check valve 107. A third motor 504 is connected to the second fixed plate 501. The output end of the third motor 504 is connected to a worm 503. The worm 503 meshes with the worm gear 502. The upper surface of the material support plate 106 is smooth. The third motor 504 drives the worm gear 502 to rotate through the worm gear 503. The worm gear 502 drives the second fixed plate 501 to rotate. The second fixed plate 501 is in contact with the material support plate 106, blocking the stacked printed materials and keeping them in the feeding trough 105.

[0033] The above embodiment discloses an automatic feeding device for a quality inspection machine. Negative pressure exists at the ventilation gap 203 within the coverage area of ​​the negative pressure box 201, attracting printed materials in direct contact with the conveyor belt 103 and causing them to move synchronously with the conveyor belt 103. A first motor 307 drives a first lead screw 306 to rotate, and a connecting plate 305 moves on the first lead screw 306. The connecting plate 305 also drives a baffle plate 302 to move up and down, limiting the height of the paper outlet 301 and allowing only one printed material to leave the feeding trough 105 at a time. Printed materials to be inspected are pre-stacked on the support plate 106. After the printed materials in the feeding trough 105 have been inspected, a telescopic rod 601 drives the feeding trough 105 to slide on a first fixed plate 104, allowing the stacked printed materials to slide back onto the support plate 105. The tray 106 containing the printed materials enters the feeding trough 105. The telescopic block 702 and the spring 703 cooperate to lock the notch 704, connecting the tray 106 and the feeding trough 105 together. The telescopic rod 601 drives the feeding trough 105 and the tray 106 to retract together. At this time, the tray 106 with the stacked printed materials is located directly above the conveyor belt 103. The third motor 504 drives the worm wheel 502 to rotate through the worm 503. The worm wheel 502 drives the second fixed plate 501 to rotate. The second fixed plate 501 is in contact with the tray 106, blocking the stacked printed materials. The second motor 405 drives the rack 403 through the gear 404, causing the tray 106 to separate from the feeding trough 105 and return the tray 106 to the initial position to wait for pre-loading.
