Description

Technical Field

[0001] This utility model belongs to the field of die-cutting machine feeding technology, specifically relating to a paper feeding channel for a die-cutting machine. Background Technology

[0002] During the paper feeding process of a die-cutting machine, workers usually need to move stacks of paper onto the paper feeding tray. The manual handling path is long, which not only requires a lot of physical strength, but also easily causes the paper to scatter or even break if the manual handling is unstable, which will have an adverse effect on the paper utilization rate and the production efficiency of the die-cutting machine. On the other hand, due to the space limitations around the paper feeding tray, large operating equipment such as forklifts cannot enter the paper feeding channel to directly feed paper onto the paper feeding tray. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a paper feeding channel for a die-cutting machine, which can effectively reduce the labor intensity of feeding, adapt to the feeding needs of different types of paper, and has a wider range of applications.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A paper feeding channel for a die-cutting machine is located on the paper-feeding side of a paper-feeding tray and connected to the feeding end of the paper-feeding tray. The key feature is that the paper feeding channel includes an inclined body and a pair of tracks. The inclined body is disposed between the tracks. The upper end of the inclined body is flush with the paper-feeding tray and connected to the feeding end. The lower end of the inclined body extends towards the paper-feeding side and overlaps the ground. The tracks are horizontally arranged and their working surfaces are higher than the inclined bodies. The feeding end is connected to the output end of the tracks.

[0006] The paper feeding tray is provided with a strip that fits into the output end of the track, and the upper surface of the strip is flush with the working surface of the track.

[0007] The horizontal length of the track is greater than the horizontal length of the inclined plane. A guide plate located in front of the inclined plane is also provided on the inner side of the track. The guide plate is set on the ground, and the upper end of the guide plate is set below the working surface of the track.

[0008] The front side of the guide plate is chamfered, and a funnel-shaped feeding channel is formed between the front sides of the two guide plates.

[0009] The sidewall of the inclined plane is fixed to the track by a set of bolts, and a horizontal mounting plate is fixed on the track and fixed to the ground by means of the horizontal mounting plate.

[0010] The inclined plane has a split structure, including a left split and a right split. The left split and the right split are respectively fixed to their respective adjacent tracks. The left split and the right split are respectively connected to the drive motor by a set of screw-connected nuts and screws. The left split and the right split have the freedom to translate in opposite directions on the horizontal plane by the drive motor. A filling split is set between the left split and the right split to form a continuous inclined plane.

[0011] The nuts are respectively installed on the left and right splits. The power output end of the drive motor is connected to the power input end of the dual-shaft output reducer. The screws are respectively connected to the output shaft of the dual-shaft output reducer. The left, right and filling splits are provided with clearance grooves for the drive motor and the dual-shaft output reducer.

[0012] The beneficial effects of this utility model are:

[0013] This utility model adopts a method of adding a horizontally set track on the paper feeding side of the paper feeding tray, with inclined bodies set between the tracks. When feeding, the corrugated paper stack that is inclined, easy to slip or crooked is lifted up and placed on the track. The corrugated paper stack is pushed along the track towards the paper feeding tray to complete the horizontal feeding. Only the front end of the corrugated paper stack needs to be lifted, and there is no need to carry the corrugated paper stack and move it for feeding throughout the process, which effectively reduces the labor intensity required for feeding.

[0014] After being stacked, ordinary cardboard has a flat bottom and high density, making it less prone to tilting due to a shift in the center of gravity when tilted. The lower end of the inclined plate overlaps the ground, effectively reducing the lifting height of the ordinary cardboard stack. Simply place the ordinary cardboard stack on the inclined plate and push it towards the paper feeding tray to complete the feeding process. The large contact area between the inclined plate and the bottom of the ordinary cardboard stack provides stable support. Pushing the ordinary cardboard stack on the inclined plate only requires overcoming the horizontal component of the stack's weight, which also reduces the labor intensity required for feeding and makes the feeding process more convenient.

[0015] This utility model combines a track and an inclined plane to form a paper feeding channel during feeding, which can meet the feeding operation of different types of paper and has a wider range of applications.

[0016] The paper feeding tray is equipped with a strip that is flush with the working surface of the track to ensure that there is no height difference when the corrugated paper stack is output from the track to the paper feeding tray, to prevent the corrugated paper stack from tilting and slipping, and to ensure that the corrugated paper stack can be smoothly transported to the paper feeding tray.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Example 1 Figure 1 As shown, this utility model relates to a paper feeding channel for a die-cutting machine, located on the paper-feeding side 2 of a paper-feeding tray 1 and connected to the feeding end 3 of the paper-feeding tray 1. Crucially, the paper feeding channel includes an inclined surface 4 and paired tracks 5. The inclined surface 4 is positioned between the tracks 5, with its upper end flush with the paper-feeding tray 1 and connected to the feeding end 3. The lower end of the inclined surface 4 extends towards the paper-feeding side 2 and overlaps the ground. The tracks 5 are horizontally positioned, and the feeding end 3 connects to the output end of the tracks 5. The upper surface of the tracks 5 is its working surface, which is higher than the height of the inclined surface 4. When feeding with the help of the tracks 5, the bottom of the paper stack does not interfere with the inclined surface 4, and the friction of the paper stack moving on the tracks 5 is reduced.

[0024] The inclined body 4 is trapezoidal, comprising an upper plane, a lower plane, and an inclined surface. The upper plane of the inclined body 4 is flush with the paper feeding tray 1. Compared to a triangular structure, the upper end of the trapezoidal inclined body 4 has a larger wall thickness, resulting in higher wear resistance.

[0025] When corrugated cardboard stacks are tilted, the cardboard is prone to skewing and slipping. Therefore, the corrugated cardboard stacks are fed using a horizontally set track 5. The corrugated cardboard stack is lifted from the paper feeding side 2 and placed on the working surface of the track 5. The corrugated cardboard stack is then pushed along the track 5 towards the paper feeding tray 1 to complete the feeding process. This eliminates the need for workers to carry the corrugated cardboard stack throughout the process. Furthermore, the small contact area between the track 5 and the corrugated cardboard stack results in low friction, making it easy to push the stack and effectively reducing the labor intensity required for feeding. For other thinner single sheets of ordinary cardboard, such as cardboard, the bottom is flat and the density is high when stacked. When tilted, it is not easy to skew due to the shift of the center of gravity. The lower end of the inclined body 4 overlaps the ground, which can effectively reduce the lifting height of the ordinary cardboard stack. The ordinary cardboard stack is placed on the inclined surface of the inclined body 4 and pushed towards the paper feeding tray 1 to complete the feeding process. Pushing the ordinary cardboard stack on the inclined body 4 only requires overcoming the horizontal component of the weight of the ordinary cardboard stack, which also reduces the labor intensity required for feeding and makes the feeding process more convenient.

[0026] This utility model uses the combination of track 5 and inclined body 4 to realize diversified feeding operations, which can meet the feeding needs of different types of paper.

[0027] Preferably, the paper feeding tray 1 is provided with a strip 6 that fits against the output end of the track 5. The strip 6 is connected to the paper feeding tray 1 by bolts. The corrugated paper stack is output from the output end of the track 5 onto the strip 6. The bottom of the corrugated paper stack does not have a large contact area with the paper feeding tray 1, so that the corrugated paper stack maintains a small friction force when moving on the paper feeding tray 1, which facilitates the sliding of the corrugated paper stack. The upper end surface of the strip 6 is flush with the working surface of the track 5 to ensure that there is no height difference when the corrugated paper stack is output from the track 5 onto the paper feeding tray 1, preventing the corrugated paper stack from tilting and slipping, and ensuring that the corrugated paper stack can be smoothly conveyed onto the paper feeding tray 1.

[0028] Preferably, the horizontal length of the track 5 is greater than the horizontal length of the inclined plane 4. A guide plate 7 is also provided on the inner side of the track 5, located in front of the inclined plane 4. The guide plate 7 is set on the ground, and the upper end of the guide plate 7 is set lower than the working surface of the track 5 to avoid interference between the corrugated paper stack and the guide plate 7 when the paper stack is fed by the track 5. The guide plate 7 guides and corrects the ordinary paper stack, so that the ordinary paper stack can smoothly reach the inclined plane 4. The front side of the guide plate 7 is chamfered, and a funnel-shaped feeding channel is formed between the front sides of the two guide plates 7, which expands the width of the feeding channel and can guide the ordinary paper stack, avoiding strong impact between the ordinary paper stack and the front side of the guide plate 7 due to position deviation during the pushing process, protecting the integrity of the paper edges and preventing the paper from falling due to impact inertia.

[0029] The sidewall of the inclined plane 4 is fixed to the track 5 by a set of bolts. The inclined plane 4 and the track 5 support each other, improving structural stability and strength. Specifically, two bolts are installed vertically on the side of the inclined plane 4 near the paper feeding plate 1, and multiple bolts are installed on the lower part of the inclined plane 4 to fix it to the track 5, improving the connection stability between the inclined plane 4 and the track 5. A horizontal mounting plate 8 is fixed on the track 5 and fixed to the ground by means of the horizontal mounting plate 8, thereby realizing the installation and fixation of the track 5 and the inclined plane 4 on the paper feeding side 2. The horizontal mounting plate 8 is fixed to the ground by bolts, which provide a stable and reliable connection between the inclined plane 4 and the track 5, and between the track 5 and the ground.

[0030] Example 2 differs from Example 1 in that, as Figure 2As shown, the track 5 is not fixed to the ground, and the inclined body 4 has a split structure. When the width between the strips 6 is less than the width of the ordinary paper to be processed by the die-cutting machine, the strips 6 can be removed from the paper feeding plate 1. The inclined plane 4 includes a left segment 9 and a right segment 10. The left segment 9 and the right segment 10 are fixedly connected to their respective adjacent tracks 5. The left segment 9 and the right segment 10 are connected to the drive motor 13 by a set of screw-connected nuts 11 and screws 12. Driven by the drive motor 13, the left segment 9 and the right segment 10 have the freedom to move in opposite directions on the horizontal plane. The ground is provided with guide rails for the left segment 9 and the right segment 10. When the left segment 9 and the right segment 10 move in opposite directions, a gap is formed between them. The filling segment 14 is used to fill the gap between the left segment 9 and the right segment 10 and form a continuous inclined plane with the left segment 9 and the right segment 10. This accommodates different paper stack widths and prevents ordinary paper stacks from drooping and getting stuck along the gap between the left segment 9 and the right segment 10. This ensures that ordinary paper stacks can be stably supported on the inclined plane 4 and move smoothly.

[0031] like Figure 3 , Figure 4 As shown, the power output end of the drive motor 13 is connected to the power input end of the dual-shaft output reducer 15. The left split 9, right split 10, and filling split 14 are provided with clearance grooves for the drive motor 13 and the dual-shaft output reducer 15. The screws 12 are respectively connected to the output shafts of the dual-shaft output reducer 15. Nuts 11 are respectively installed on the left split 9 and right split 10. The drive motor 13 and the dual-shaft output reducer 15 are fixedly connected to the ground. When the screws 12 and nuts 11 are screwed together, the drive motor 13 rotates forward, and the output shaft of the dual-shaft output reducer 15 drives the screws 12 to rotate forward. The two nuts 11 move on their respective matching screws 12 and move in opposite directions, thus realizing the reverse movement of the left split 9 and right split 10. When the drive motor 13 rotates in reverse, the output shaft of the dual-shaft output reducer 15 drives the screws 12 to rotate in reverse, and the two nuts 11 move towards each other, thus realizing the opposite translation of the left split 9 and right split 10. Adjust the distance between the left split 9 and the right split 10 according to different paper widths, and select a suitable filling split 14 according to the paper width. The left split 9 and the right split 10 clamp the filling split 14 to prevent it from shaking during the feeding of ordinary paper stacks. The track 5 moves with the opposite movement of the left split 9 and the right split 10, so that the guide plate 7 can effectively guide the ordinary paper stacks to be fed.
