Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a feeding and paper pushing device for carton production. Background Art

[0002] When producing cartons, the raw cardboard needs to be transported to the die-cutting production line. The die-cutting machine can cut the raw cardboard into the required shape and size. The carton raw materials are mostly stacked in large quantities. When cutting, the individual cardboard raw materials need to be placed on the conveyor belt of the die-cutting machine in sequence. The existing cardboard placement operation is mostly completed manually. When die-cutting is required, the stacked raw cardboard is pushed to the front of the die-cutting machine, and the operator evenly places the individual cardboard on the conveyor belt. However, this manual placement and loading method has the following defects: the operation is cumbersome and time-consuming and labor-intensive. At the same time, after a long time of placement and loading, the operator is prone to fatigue, resulting in uneven placement and loading speed, making the distance between two adjacent raw cardboards too large or too small, affecting the subsequent die-cutting operation. Utility Model Content

[0003] In view of the above situation, in order to make up for the shortcomings of the prior art, the purpose of the utility model is to provide a paper feeding and pushing device for carton production, which effectively solves the problems of cumbersome operation, time-consuming and labor-intensive operation and uneven feeding speed during manual feeding.

[0004] The technical solution is as follows: the utility model comprises a bottom plate, a U-shaped protective plate is provided at the upper end of the bottom plate, a rectangular raw material plate is slidably connected to the protective plate, a plurality of cardboards evenly distributed in the up and down directions are stacked on the upper end of the raw material plate, an L-shaped support plate is respectively provided on the front and rear sides of the upper end of the protective plate, a front and rear axial and rotatable rotating shaft is provided between the two support plates, a rotating column is coaxially provided on the rotating shaft, a telescopic hole is provided at the left end of the rotating column, a telescopic column is connected to the bottom surface of the telescopic hole via a compression spring, an arc-shaped material-diverting plate that can contact with the cardboard is provided at the left end of the telescopic column, a rectangular rising block is provided at the lower end of the raw material plate, a plurality of sliding grooves that are lower on the left and higher on the right and evenly distributed in the up and down directions are provided at the front end of the rising block, a rack is provided on the protective plate that is located in front of the rising block and can move left and right, a sliding block is hingedly connected to the rear end of the rack via an articulated column in the up and down directions, an inserting column that can be inserted into the sliding groove is provided at the rear end of the sliding block, and a pressing plate that is located on the right side of the sliding block and can contact with the sliding block is provided at the rear end of the rack.

[0005] Compared with the prior art, the beneficial effect of the utility model is that it can automatically push the stacked material cardboards individually onto the conveyor belt of the die-cutting machine.

A rack 12 which is located in front of the rising block 10 and can move left and right is provided on the protective plate 2. A slider 13 is hinged to the rear end of the rack 12 through upper and lower axial hinge columns. A plug column 14 which can be inserted into the slide groove 11 is provided at the rear end of the slider 13. A pressure plate 15 which is located on the right side of the slider 13 and can contact the slider 13 is provided at the rear end of the rack 12.

[0019] In order to allow the rack 12 to slide left and right, the protective plate 2 is provided with a sliding column 16 with a left and right axial direction and slidingly connected to the rack 12. A fixed plate is provided at the front end of the protective plate 2, and a power column 17 is rotatably connected to the fixed plate with a front and rear axial direction. An incomplete gear 18 is coaxially provided at the rear end of the power column 17 and is located below the rack 12 and can mesh with the rack 12. The power column 17 rotates synchronously with the rotating shaft 6.

[0020] In order to make the power column 17 rotate synchronously with the rotating shaft 6, the rotating shaft 6 and the power column 17 are respectively coaxially provided with pulleys 19 located in front of the protective plate 2, the two pulleys 19 are connected by belts, and a motor 20 is provided in the fixed plate, and the output shaft of the motor 20 is coaxially fixedly connected with the power column 17.

[0021] In order to facilitate the reset of the slider 13 and the plug post 14, a torsion spring is provided on the hinge post.

[0022] In order to facilitate the resetting of the rack 12 , a baffle is coaxially provided at the left end of the slide post 16 , and a spring is sleeved on the slide post 16 and located between the baffle and the rack 12 .

[0023] In order to facilitate the fixed limiting of the rising block 10, a plurality of limiting grooves 21 corresponding to the sliding grooves 11 are opened at the left end of the rising block 10, and a horizontal block 23 slidably connected to the rising block 10 is provided on the protective plate 2. A yield groove is opened in the horizontal block 23, and a limiting block 22 that can be inserted into the limiting groove 21 is slidably connected in the yield groove, and the right end face of the limiting block 22 is an inclined surface.

[0024] In order to facilitate the release of the fixed limit, a pull column is provided at the left end of the limit block 22. The left end of the pull column passes through the cross block 23 and is provided with a pull plate. A return spring located between the limit block 22 and the cross block 23 is sleeved on the pull column.

[0025] When the utility model is in use, the bottom plate 1 is first moved to the left side of the conveyor belt of the die-cutting machine, and then the motor 20 is turned on at this time, and the motor 20 drives the power column 17 to rotate counterclockwise, and the power column 17 rotates the rotating shaft 6 through the belt and the pulley 19, and then drives the material-digging plate 9 to rotate counterclockwise through the rotating column 7. After the material-digging plate 9 rotates counterclockwise at a certain angle, the surface contacts a carton at the top of the stacked materials, and drives the carton at the top to move to the right. After moving to the right for a certain distance, it is pushed to the conveyor belt of the die-cutting machine for transportation and die-cutting;

[0026] At this time, the material stripping plate 9 is out of contact with the raw material paperboard 4. Due to the action of the pulley 19 and the belt, the rotating shaft 6 and the power column 17 rotate at the same time. At this time, the power column 17 drives the incomplete gear 18 to rotate counterclockwise until it contacts the rack 12, and drives the rack 12 to move to the left. The rack 12 drives the plug column 14 to move to the left. After moving to the left for a distance, the plug column 14 is inserted into the uppermost slide groove 11. At this time, due to the obstruction of the pressure plate 15, the slider 13 cannot swing to the right, so it drives the rising block 10 After moving upward for a distance, it slides out of the slide groove 11. At this time, the incomplete gear 18 is out of contact with the rack 12. Due to the rightward restoring force of the spring, the rack 12 is driven to slide to the right. The rack 12 drives the slider 13 and the plug post 14 to slide to the right. After sliding to the right for a distance, the plug post 14 contacts the rising block 10. At this time, since there is no obstruction, the slider 13 and the plug post 14 rotate around the hinge axis, and the plug post 14 cannot be inserted into the slide groove 11. After sliding to the right for a distance, the rack 12 returns to the initial position;

[0027] After the rising block 10 moves upward for a short distance, the top carton moves to the initial position again. At this time, the material-diverting plate 9 rotates again to contact with the cardboard 4, and drives the top cardboard 4 to move rightward to the conveyor belt again. After the material diversion is completed, the incomplete gear 18 contacts with the rack 12 again and drives the rack 12 to move leftward again. After moving to the left for a distance, the plug post 14 is inserted into the chute 11 again and drives the raw material cardboard 4 to move upward for a distance again. This is repeated. When the material-diverting plate 9 diverts the top cardboard 4 to the right onto the conveyor belt, the incomplete gear 18 contacts with the teeth and drives the rising block 10 to move upward for a distance so that the material-diverting plate 9 can divert the material again.

[0028] When the rising block 10 moves upward, it also drives the limit block 22 on it to move upward. Since the right end face of the limit block 22 is an inclined surface, it moves to the left after being squeezed. When it is aligned with the next limit groove 21, the restoring force of the return spring causes the limit block 22 to be inserted into the limit groove 21 again to achieve fixed limit. When the limit needs to be released, it can be achieved by pulling the pull plate to the left.

[0029] Compared with the prior art, the beneficial effects of the utility model are: the provided material stripping plate, rack, incomplete gear, etc. can realize automatic pushing of stacked material cardboards individually to the conveyor belt of the die-cutting machine. Compared with the traditional manual pushing and loading, the operation is simple and time-saving and labor-saving. At the same time, the loading speed is uniform, which prevents the distance between two adjacent raw material cardboards from being too large or too small, resulting in inaccurate die-cutting. The structure is simple, the concept is novel, the use is convenient, and the practicability is strong.

[0030] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0031] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
