It can be understood that the specific embodiments described herein are only used to explain the related utility model, and not to limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the parts related to the utility model are shown in the drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4 As shown, this utility model provides a separating and feeding device for cardboard processing, including: a worktable 1, a lifting mechanism, a limiting baffle 3, and a pushing component 4.

[0030] The workbench 1 has a rectangular surface. The workbench 1 has a strip-shaped through hole a, which is set along the width direction of the workbench 1.

[0031] The lifting mechanism includes two support frames 2, which are arranged opposite to each other. The support frames 2 are adjustablely installed on the worktable 1 along its length, and the two support frames 2 are respectively located on opposite sides of the strip-shaped through hole a. The worktable 1 has a clearance opening b, and the lower part of the support frame 2 is movably inserted through the clearance opening b and extends to the bottom of the worktable 1.

[0032] Specifically, multiple locking holes d are provided on opposite sides of the workbench 1, and these locking holes d are spaced apart along the length of the workbench 1. Ear plates 22 are connected to opposite sides of the support frame 2, and each ear plate 22 has a positioning hole. A locking rod 23 is detachably installed in the positioning hole and a locking hole d. In this embodiment, the wall of the locking hole d has an internal thread. One end of the locking rod 23 has a limiting flange, and the outside of the locking rod 23 has an external thread. The locking rod 23 is movably inserted through the positioning hole of the ear plate 22 and screwed into a locking hole d on the workbench. When the locking rod 23 is tightened, the limiting flange presses against the upper part of the ear plate 22, thereby locking the support frame 2.

[0033] Multiple support seats 21 are vertically mounted on the support frame 2, and the multiple support seats 21 are spaced apart along the height direction of the support frame 2. The support seats 21 corresponding to the positions of two support frames 2 form a support platform for placing cardboard. A drive assembly for driving the support seats 21 is mounted on the support frame 2.

[0034] In this embodiment, the drive assembly includes two rollers 61, a transmission chain 62, and a drive motor 63.

[0035] Specifically, in combination Figures 1 to 3 As shown, the support frame 2 has an assembly hole e that extends through both sides of the support frame 2. A roller shaft 61 is rotatably mounted in the assembly hole e. Two roller shafts 61 are spaced apart along the height direction of the support frame 2, with one roller shaft mounted at the upper part of the assembly hole e and the other roller shaft mounted at the lower part of the assembly hole e.

[0036] A sprocket is coaxially connected to each roller shaft 61. In this embodiment, two sprockets are coaxially connected to each of the two roller shafts 61. Correspondingly, there are two transmission chains 62, with both ends of the transmission chains 62 meshing with the sprockets of the two roller shafts 61 respectively. A support seat 21 is mounted on the two transmission chains 62.

[0037] The drive motor 63 is mounted on the support frame 2 and is connected to a roller shaft 61. After the drive motor 63 is started, it drives the roller shaft 61 to rotate, thereby causing the transmission chain 62 to rotate around the sprockets of the two roller shafts 61, which in turn causes the support seat 21 to move up and down with the transmission chain 62.

[0038] A limiting baffle 3 is vertically installed on the workbench 1, and the limiting baffle 3 is set along the length of the workbench 1, spanning one end of the strip-shaped perforation a. The lower part of the limiting baffle 3 has a discharge notch c for the paperboard to pass through.

[0039] See Figure 4 As shown, in a preferred embodiment, the upper inner wall of the discharge notch c is provided with a receiving groove, in which an adjusting plate 7 is vertically mounted. To make the adjusting plate 7 move more smoothly, in this embodiment, the inner walls of opposite ends of the discharge notch c are formed with vertically arranged sliding grooves, and sliders are connected to both ends of the adjusting plate 7, which slide in the sliding grooves. The limiting baffle 3 is equipped with a driving component for driving the adjusting plate 7.

[0040] Specifically, a support flange 71 is formed on the side of the adjusting plate 7 away from the support frame 2. A support 31 is installed on the outer side of the limiting baffle 3, and the support 31 has a threaded through hole, which is vertically arranged. The driving component is a screw 32, which is screwed into the threaded through hole, and the lower end of the screw 32 is rotatably connected to the support flange 71.

[0041] Combination Figure 1 , Figure 2 and Figure 4 As shown, a belt conveyor 5 is installed below the workbench 1, and the belt conveyor 5 is arranged along the length direction of the strip perforation a. One end of the pusher 4 is movably inserted through the strip perforation a and connected to the conveyor belt of the belt conveyor 5, and the other end of the pusher 4 extends above the workbench 1. In this embodiment, the height of the pusher 4 above the workbench surface is less than the thickness of a single sheet of cardboard, and the distance between the adjusting plate 7 and the workbench 1 is greater than the thickness of a single sheet of cardboard but less than the thickness of two sheets of cardboard, so that the pusher 4 can smoothly push a single bottom sheet of cardboard, thereby separating the bottom sheet of cardboard from the top sheet of cardboard.

[0042] Continue reading Figure 1 As shown, when using the separation and feeding device for cardboard processing of this utility model, first adjust the distance between the two support frames 2 according to the size of the cardboard, and then adjust the distance between the adjusting plate 7 and the worktable 1 by rotating the screw 32 according to the thickness of the cardboard.

[0043] After a predetermined number of stacked cardboard pieces are placed on each support platform, the drive motor 63 is started. The drive motor 63 drives the roller shaft 61 to rotate, and the roller shaft 61 drives the sprocket to rotate, thereby causing the transmission chain 62 to rotate around the sprocket of the two roller shafts 61, which in turn causes the support seat 21 to descend with the transmission chain 62.

[0044] After the drive assembly lowers the bottom support 21 into the clearance opening b, the cardboard stacked on the bottom support platform is placed on the workbench 1. Then, the belt conveyor 5 is started, and the belt conveyor 5 drives the pusher 4 to push the bottom cardboard of the cardboard stack on the workbench 1, so that the bottom cardboard slides through the discharge notch c to the outside of the limiting baffle 3. The upper cardboard is supported by the limiting baffle 3 and the adjusting plate 7, thereby separating the bottom cardboard from the upper cardboard. After separation, the bottom cardboard is transported to the cardboard processing equipment (belt conveyor, roller conveyor, etc.) for the next processing step through the conveying equipment. The separation and feeding of the cardboard on the bottom support platform is completed by the reciprocating push of the pusher 4.

[0045] After the cardboard on the bottom support platform is separated and loaded, the drive component lowers the cardboard on the remaining support platforms to the worktable 1 in sequence, and completes the separation and loading of all cardboard by the reciprocating push of the pusher 4.

[0046] In a preferred embodiment, the workbench 1 has multiple receiving grooves on its surface, and ball bearings 11 are rotatably embedded in these grooves. By installing the ball bearings, the friction between the cardboard and the workbench 1 surface is further reduced when the pusher 4 pushes the bottom cardboard, making the pushing of the cardboard smoother.

[0047] In a preferred embodiment, the workbench 1 has an assembly slot on its surface, in which a distance sensor 12 is installed. The distance sensor 12, the drive motor 63, and the belt conveyor 5 are signal-connected to a controller. The distance sensor 12 is used to sense the distance between itself and the cardboard. When the cardboard (cardboard on the bottom support platform) on the workbench is pushed out, and the distance value exceeds a preset threshold, the controller starts the drive motor 63, thereby lowering the upper support platform by a preset distance, so that the cardboard on the upper support platform rests on the workbench 1. Then, the controller starts the belt conveyor 5, causing the pusher 4 to continue pushing the cardboard on the upper support platform.

[0048] This invention relates to a separating and feeding device for cardboard processing. The distance between the two support frames and the distance between the adjusting plate and the worktable are adjustable, thus adapting to the separating and feeding of cardboard of different sizes. This separating and feeding device divides thicker stacks of cardboard into multiple thinner stacks, placing them onto multiple support platforms. This ensures that the number of cardboard pieces on each support platform is within a reasonable range. Furthermore, during the pushing process, the pressure on the bottom stack of cardboard is reduced, thus minimizing wear. This improves cardboard separation efficiency and reduces the need for workers to constantly monitor cardboard levels and frequently replenish the stock.

[0049] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
