DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figure 1-5 , the present invention provides a technical solution:

[0027] A combined cardboard introduction device includes a conveying seat 1 and a conveyor belt 2. A splicing frame 3 is fixedly installed on the outer wall of the conveying seat 1. A connecting seat 6 is fixedly installed on the top of the splicing frame 3 and the conveying seat 1. A top frame 1 7 and a top frame 2 8 are fixedly installed on the top of the two groups of connecting seats 6, and the cross-sections of the top frame 1 7 and the top frame 2 8 are both L-shaped. The bottoms of the top frame 1 7 and the top frame 2 8 are simultaneously slidably connected with a movable plate 9. A driving component for pushing the movable plate 9 to reciprocate at the horizontal end is provided on the top of the splicing frame 3. The movable plate 9 includes an integrally formed separating cardboard 901 and a closing plate 902. A card slot is opened on the top of the separating cardboard 901, and a pushing mechanism for pushing the cardboard out of the card slot is provided on the outer wall of the top frame 2 8.

[0028] In the initial state, the stacked cardboards are placed between the top frame 1 7 and the top frame 2 8, and the bottom cardboard contacts the closing plate 902. Then the conveyor belt 2 and the pushing cylinder 5 work, and the pushing cylinder 5 pulls the overall movable plate 9. The movable plate 9 will slide against the bottom of the top frame 1 7 and the top frame 2 8 until the dividing cardboard 901 is located below the top frame 1 7 and the top frame 2 8. At this time, the bottom cardboard will be combined with the inside of the card slot at the top of the dividing cardboard 901. Then the pushing cylinder 5 pushes the movable plate 9, so that the closing plate 902 is gradually combined with the bottom of the top frame 1 7 and the top frame 2 8. During this process, the push plate 14 will rotate, and the push plate 14 will overlap in the card slot. The top of the cardboard is pushed away and moves along the bevel 16 to the conveyor belt 2, so that the cardboard is evenly spaced on the conveyor belt 2. In the process of cardboard introduction, the cardboard can be continuously placed from above the top frame 7 and the top frame 2 8, thereby improving the use effect of the cardboard introduction device.

[0029] Specifically, such as Figure 2 and Figure 4 As shown, the outer wall of the longitudinal end of the conveying seat 1 is elastically connected with two groups of limit strips 10 through two groups of springs 13. The top of the two groups of limit strips 10 are fixedly installed with a fixing frame 11. A sliding component for pushing the limit strip 10 to move is provided between the fixing frame 11 and the dividing paper board 901. When the pushing cylinder 5 pulls the movable plate 9 back, the limit strip 10 and the fixing frame 11 will gradually move away from the paper board under the action of the spring 13, and can maintain the fitting state of the inclined surface 18 and the inclined surface 20. Then, in the process of pushing the movable plate 9 to move horizontally by the pushing cylinder 5, the inclined surface 18 will push the convex seat 19 through the sliding cooperation with the inclined surface 20, and the convex seat 19 is linked and fixed. The fixed frame 11 and the limit strips 10 are arranged so that the two groups of limit strips 10 can perform relative movement of a specified distance at the longitudinal ends, so that when the movable plate 9 reciprocates to introduce the cardboard, the two groups of limit strips 10 can synchronously perform relative movement of the longitudinal ends, thereby correcting the position of the cardboard on the conveyor belt 2, avoiding the cardboard from being offset during the transfer process, and making the position of the cardboard consistent when contacting the subsequent printing components. At the same time, since the vertical height of the fixed frame 11 is fixed, the fixed frame 11 can provide auxiliary support for the movable plate 9, ensuring the stable movement of the movable plate 9, thereby improving the stability of the combined cardboard introduction device.

[0030] Specifically, such as Figure 2 and Figure 3As shown, a telescopic rod 12 is fixedly installed between the limit bar 10 and the conveying seat 1, and the outer wall of the telescopic rod 12 abuts against the inner wall of the spring 13. The telescopic rod 12 can be longitudinally extended and retracted to conform to the movement law of the spring 13, thereby limiting the vertical displacement of the spring 13. The sliding assembly includes a slide groove 17 slidably connected to the fixed frame 11, and the slide groove 17 is provided with a slope 18. A convex seat 19 is fixedly installed at the open end of the fixed frame 11, and the convex seat 19 is provided with a slope 20 that slides with the slope 18. The slope 18 will push the convex seat 19 by sliding with the slope 20. The convex seat 19 links the fixed frame 11 and the limit bar 10, so that the two groups of limit bars 10 can perform relative movement of a specified distance at the longitudinal end.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the driving component includes a push cylinder 5, which is fixedly connected to the splicing frame 3, and the output end of the push cylinder 5 is fixedly connected to the sealing plate 902, so that the movable plate 9 is driven to reciprocate at the horizontal end by the push cylinder 5. A support column 4 is provided below the push cylinder 5, and the support column 4 is fixedly connected to the bottom of the splicing frame 3, so that the overall force of the device is uniform, and the stability of the device is ensured. The pushing component includes a push plate 14, and the push plate 14 is in contact with the inner surface wall of the horizontal end of the top frame 2 8, and the side of the push plate 14 close to the dividing paper board 901 is flush with the outer surface wall of the top frame 2 8, and the top of the push plate 14 is hinged to the inner surface wall of the top frame 2 8, and the sealing plate 902 is gradually combined to the bottom of the top frame 1 7 and the top frame 2 8. In this process, the push plate 1 4 will rotate, and the push plate 14 will overlap the top of the cardboard inside the card slot and move with it until the push plate 14 is vertically mounted above the bevel 15, and then the push cylinder 5 pulls the movable plate 9, and the dividing cardboard 901 is gradually combined to the bottom of the top frame 7 and the top frame 2 8. In this process, the push plate 14 is constrained by the top frame 2 8 and remains in a vertical state. The push plate 14 will push the cardboard on the top of the dividing cardboard 901 away, and the bottom of the card slot is provided with a bevel 16. The bevel 16 can make the cardboard quickly detach from the card slot while making it stably contact the conveyor belt 2. The side of the sealing plate 902 close to the dividing cardboard 901 is provided with a bevel 15, which provides ample working space for the push plate 14, so that the cardboard can be pushed stably.

[0032] Working principle: In the initial state, the stacked cardboards are placed between the top frame 1 7 and the top frame 2 8, and the bottom cardboard is in contact with the sealing plate 902. Then the conveyor belt 2 and the pushing cylinder 5 work, and the pushing cylinder 5 pulls the overall moving plate 9. The moving plate 9 will slide against the bottom of the top frame 1 7 and the top frame 2 8 until the separating cardboard 901 is located below the top frame 1 7 and the top frame 2 8. At this time, the bottom cardboard will be combined with the inside of the card slot at the top of the separating cardboard 901. Then the pushing cylinder 5 pushes the moving plate 9, so that the sealing plate 902 is gradually combined with the bottom of the top frame 1 7 and the top frame 2 8. During this process, the push plate 14 will rotate, and the push plate 14 will overlap the top of the cardboard inside the card slot and move with it until the push plate 14 is vertically mounted above the bevel 15, and then the push cylinder 5 will pull the moving plate 9, and the cardboard 901 will gradually be combined under the top frame 1 7 and the top frame 2 8. During this process, the push plate 14 is constrained by the top frame 2 8 and remains in a vertical state. The push plate 14 will push the cardboard on the top of the cardboard 901 away, and the cardboard will slide along the bevel 16 to the conveyor belt 2, and reciprocate in this way, thereby realizing the equidistant introduction of the cardboard on the conveyor belt 2, and when the cardboard is introduced During the process of pushing the movable plate 9 horizontally, the cardboard can be continuously placed from above the top frame 1 7 and the top frame 2 8, thereby improving the use effect of the cardboard introduction device. When the push cylinder 5 pulls the movable plate 9 to move back, the limit strip 10 and the fixed frame 11 will gradually move away from the cardboard under the action of the spring 13, and can maintain the fitting state of the inclined surface 18 and the inclined surface 20. Then, when the push cylinder 5 pushes the movable plate 9 horizontally, the inclined surface 18 will push the convex seat 19 through the sliding cooperation with the inclined surface 20, and the convex seat 19 links the fixed frame 11 and the limit strip 10, so that the two sets of limit strips 10 are in the longitudinal direction. The two sets of limit strips 10 can make relative movements of a specified distance toward the ends, so that in the process of reciprocating movement of the movable plate 9 to introduce the cardboard, the two sets of limit strips 10 can synchronously make relative movements of the longitudinal ends, so as to correct the position of the cardboard on the conveyor belt 2, avoid the cardboard from being offset during the transfer process, and make the cardboard consistent in position when contacting the subsequent printing components. At the same time, since the vertical height of the fixing frame 11 is fixed, the fixing frame 11 can provide auxiliary support for the movable plate 9, ensuring the stable movement of the movable plate 9, thereby improving the stability of the combined cardboard introduction device.
