Description

Technical Field

[0001] This application relates to the technical field of cardboard production equipment, and in particular to a receiving mechanism for cutting packaging cardboard for furniture boards. Background Technology

[0002] Currently, furniture board packaging paperboard is generally made of one or more layers of corrugated core paper and two face papers bonded together by a hot-pressing process. During the production of furniture board packaging paperboard, companies need to cut the corrugated paperboard to the required dimensions. The cut corrugated paperboard is then received and stacked by a receiving mechanism or stacking machine, ready for the next production step.

[0003] Existing corrugated paper stacking machines, such as the patent with publication number CN206842679U, disclose a corrugated paper stacking machine including a paper feeding section and a stacking section. The paper feeding section includes a conveyor belt. The stacking section is characterized by including a lifting mechanism, a support platform, a paper receiving platform, a traction rope, and a traction wheel. The lifting mechanism is located at the bottom of the support platform, which is inclined and has a set of grooves on its surface. The paper receiving platform is L-shaped and has legs at its bottom that fit the grooves. A baffle is located on one side of the receiving platform, fixedly connected to the support platform at a 90° angle. Both ends of the support platform are connected to the traction rope, and the upper end of the traction rope is connected to the traction wheel. A guide plate is provided between the paper feeding section and the stacking section. The guide plate is grooved and contains antistatic pins.

[0004] When the above device is used for receiving materials in a paper cutter, because the size of the device is fixed, it is only suitable for the production process of a certain specification of corrugated cardboard, which will cause the problem that it is difficult to adapt to multiple specifications of cardboard due to the fixed size of the device. Utility Model Content

[0005] To address the problem of difficulty in adapting to various specifications of cardboard due to fixed device dimensions, this application provides a receiving mechanism for cutting packaging cardboard for furniture boards.

[0006] The material receiving mechanism for cutting furniture board packaging cardboard provided in this application adopts the following technical solution:

[0007] A receiving mechanism for cutting furniture board packaging cardboard includes a receiving platform, a receiving plate, a baffle plate, and two limiting plates. The receiving platform is mounted on the ground and has a receiving inlet end and a receiving baffle end. The receiving plate is connected to the receiving platform at one end near the receiving baffle end. The baffle plate is installed on the receiving plate at one end near the receiving baffle end. The two limiting plates are installed opposite each other on the top of the receiving platform and are located on both sides of the receiving plate. The two limiting plates move in a direction that moves closer to or further away from each other. The receiving platform is provided with an adjustment component for driving the movement of the limiting plates.

[0008] By adopting the above solution, the problem of the receiving mechanism being unable to adapt to various specifications of cardboard has been improved.

[0009] Furthermore, the adjustment assembly includes a positive and negative threaded screw, a rotating handle, and two screw nuts; the positive and negative threaded screw is installed on the top of the receiving platform and located at the bottom of the receiving plate. The positive and negative threaded screw is rotatably connected to the receiving platform. The two screw nuts correspond one-to-one with two limiting plates. Each of the two limiting plates has an adjustment hole. The two screw nuts are fixedly installed on the plate surface of the corresponding limiting plate away from the receiving plate. The threaded holes of the two screw nuts are coaxial with the adjustment holes on the corresponding limiting plates. The two limiting plates are threadedly connected to the positive and negative threaded screws through the corresponding screw nuts. The rotating handle is fixedly connected to the positive and negative threaded screws.

[0010] By adopting the above scheme, the distance between the two limiting plates can be adjusted.

[0011] Furthermore, two sets of rollers are installed at both ends of the bottom of the two limiting plates, and the axis of each set of rollers is parallel to the positive and negative threaded rods.

[0012] By adopting the above solution, the friction between the limiting plate and the receiving platform during the adjustment process can be reduced, making the adjustment work more labor-saving.

[0013] Furthermore, the receiving plate is rotatably connected to the receiving platform via a receiving shaft. The receiving shaft is installed on the top of the receiving platform near the receiving stop end, and the axis of the receiving shaft is perpendicular to the surface of the limiting plate.

[0014] By adopting the above solution, falling cardboard can be caught.

[0015] Furthermore, the receiving plate has four through holes, and the receiving platform is equipped with four receiving posts. The four through holes correspond one-to-one with the four receiving posts, and the receiving posts can pass through the corresponding through holes.

[0016] By adopting the above solution, a gap is left between the cardboard stack and the receiving plate, which facilitates handling.

[0017] Furthermore, the receiving mechanism also includes a material transfer component that can convey the cardboard to the receiving station.

[0018] By adopting the above method, the cardboard can be conveyed to the receiving station.

[0019] Furthermore, the material transfer assembly includes a material transfer platform, a bottom support, and a lifting component. The material transfer platform has a material inlet and a material outlet, with the material outlet close to the material inlet. Several pulleys are evenly installed on the material transfer platform, each pulley being rotatably connected to the material transfer platform. The bottom of the bottom support, near the material inlet, is fixedly connected to the material receiving platform, while the other end is placed on the ground. The top of the bottom support, near the material inlet, is rotatably connected to the bottom of the material transfer platform near the material outlet. The lifting component is adjustable in length and is installed on the bottom support at the end away from the material inlet. One end of the lifting component is rotatably connected to the bottom support, and the other end is rotatably connected to the bottom of the material transfer platform near the material inlet. The material inlet is always higher than the material outlet. When the material inlet is lowered to its lowest position, the bottom of the material transfer platform contacts the bottom support.

[0020] By adopting the above solution, it is possible to adapt to cardboard cutting machines of different heights.

[0021] Furthermore, a tension spring is installed on the receiving plate. The tension spring is installed on the receiving plate near the receiving feed end. One end of the tension spring is connected to the receiving plate, and the other end is connected to the bottom of the conveyor. Under the action of the tension spring, the end of the receiving plate near the receiving feed end is higher than the end of the receiving plate near the receiving stop end.

[0022] By adopting the above solution, the problem of cardboard flipping and standing up during the initial receiving process, which is caused by the large height difference between the receiving plate and the transfer table, can be improved, making it impossible to stack the cardboard normally.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. The installation of the limiting plate improves the problem of difficulty in adapting to various specifications of cardboard due to the fixed size of the device;

[0025] 2. The installation of the material conveying assembly can be adapted to cardboard cutting machines of different heights;

[0026] 3. The installation of tension springs improves the problem that the cardboard would flip and stand up during the initial receiving process due to the large height difference between the receiving plate and the conveyor table, making it impossible to stack the cardboard properly.

[0032] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] This application discloses a receiving mechanism for cutting furniture board packaging cardboard. (Refer to...) Figure 1 It includes a receiving platform 1, a receiving plate 2, a baffle plate 3, and two limiting plates 4. The receiving platform 1 is erected on the ground and has a receiving inlet end and a receiving baffle end. The receiving plate 2 is located on the top of the receiving platform 1. An installation plate 31 is installed on the end of the receiving plate 2 near the receiving baffle end. A receiving shaft 32 is fixedly installed on the installation plate 31 and is rotatably connected to the top of the receiving platform 1. A baffle plate installation groove 311 is opened on the installation plate 31, and the bottom of the baffle plate 3 is engaged with the baffle plate installation groove 311. The angle between the receiving plate 2 and the baffle plate 3 is 90°. The two limiting plates 4 are installed opposite each other between the receiving inlet end and the receiving baffle end, and the two limiting plates 4 are located on both sides of the receiving plate 2. The two limiting plates 4 can move in a direction that moves closer to or further away from each other.

[0034] The receiving platform 1 is equipped with an adjustment assembly 5 that can adjust the distance between two limiting plates 4. The adjustment assembly 5 includes a positive and negative threaded rod 52, a rotating handle 53, and two threaded rod nuts 51. The positive and negative threaded rod 52 is installed on the top of the receiving platform 1 and located at the bottom of the receiving plate 2. The positive and negative threaded rod 52 is rotatably connected to the receiving platform 1. The two threaded rod nuts 51 correspond one-to-one with the two limiting plates 4. Each of the two limiting plates 4 has an adjustment hole 41. The two threaded rod nuts 51 are fixedly installed on the side of the corresponding limiting plate 4 away from the receiving plate 2. The threaded holes of the two threaded rod nuts 51 are coaxial with the adjustment holes 41 on the corresponding limiting plates 4. The two limiting plates 4 are threadedly connected to the positive and negative threaded rod 52 through the corresponding threaded rod nuts 51. The rotating handle 53 is fixedly connected to the positive and negative threaded rod 52. The operator rotates the handle 53, which drives the positive and negative threaded rods 52 to rotate. Since the threads at both ends of the positive and negative threaded rods 52 are symmetrically distributed, the two threaded rod nuts 51 move synchronously in the direction of approaching or moving away from each other, so that the two limit plates 4 move in the direction of approaching or moving away from each other.

[0035] Reference Figure 2 To make adjusting the limiting plates 4 easier, two rollers 42 are installed at both ends of the bottom of each limiting plate 4, and the two rollers 42 on the same limiting plate 4 are located on both sides of the positive and negative threaded rods 52. Each roller 42 is rotatably connected to the corresponding limiting plate 4, and the axis of each roller 42 is perpendicular to the surface of the baffle plate 3. A limiting groove 11 is opened on the top of the receiving platform 1, and the bottom of the two limiting plates 4 is installed in the limiting groove 11, with each roller 42 rollingly connected to the bottom of the limiting groove 11.

[0036] Reference Figure 3 The limiting groove 11 is equipped with four receiving posts 12 that allow a certain gap between the bottom of the cardboard stack and the top of the receiving plate 2. The four receiving posts 12 are arranged linearly in pairs. The receiving plate 2 has four through holes 21, which correspond one-to-one with the four receiving posts 12. The receiving posts 12 can pass through the through holes 21.

[0037] The receiving mechanism also includes a material transfer component 6, which includes a material transfer platform 61, a bottom support 62, and a lifting component 63. The material transfer platform 61 has a material inlet end and a material outlet end, with the material inlet end always higher than the material outlet end and the material outlet end close to the receiving inlet end. Several pulleys 611 are evenly installed on the material transfer platform 61, and each pulley 611 is rotatably connected to the material transfer platform 61. The bottom end of the bottom support 62, near the receiving inlet end, is fixedly connected to the receiving platform 61, and the other end is mounted on the ground. The top end of the bottom support 62, near the receiving inlet end, is rotatably connected to the bottom of the material outlet end of the material transfer platform 61. The lifting component 63 is installed on the bottom support at the end away from the receiving inlet end. One end of the lifting component 63 is rotatably connected to the bottom support 62, and the other end is rotatably connected to the bottom of the material transfer platform 61 near the material inlet end. When the lifting component 63 lowers the material inlet end to the lowest position, the bottom of the material transfer platform 61 contacts the bottom support 62. In this embodiment, the lifting component 63 is a cylinder.

[0038] A tension spring 7 is installed on the receiving plate 2. The tension spring 7 is installed on the receiving plate 2 near the receiving feed end. One end of the tension spring 7 is connected to the receiving plate 2, and the other end is connected to the bottom of the material discharge end of the conveying table 61. Under the elastic force of the tension spring 7, the end of the receiving plate 2 near the receiving feed end is higher than the end of the receiving plate 2 near the receiving stop end.

[0039] The implementation principle of the receiving mechanism for cutting furniture board packaging cardboard in this application embodiment is as follows: The operator adjusts the lifting component 63 to adapt to the cutting machine of different heights, and the operator adjusts the distance between the two limit plates 4 by rotating the handle 53 to adapt to the cardboard of different specifications, so that the cardboard falling on the receiving table 1 is in a stacked state. The cardboard to be cut enters from the feeding end of the conveying table 61. The feeding end is higher than the discharging end. The cardboard is transported to the discharging end by gravity through the pulley 611 and then falls onto the receiving plate 2. Since the end of the receiving plate 2 near the receiving feeding end is higher than the end near the receiving stop end, the cardboard will be blocked and aligned by the stop plate 3. Due to the action of the tension spring 7, as more and more cardboard falls onto the receiving plate 2, the end of the receiving plate 2 near the receiving feeding end is slowly pressed down. In the initial state, the receiving column 12 is located at the bottom of the receiving plate 2, and the receiving plate 2 is kept tilted under the action of the tension spring 7. As the weight of the cardboard stack gradually increases, the end of the receiving plate 2 near the receiving feed end is pressed down, and the through hole 21 moves down accordingly. The receiving posts 12 gradually protrude from the plate surface. Finally, all four receiving posts 12 protrude from the receiving plate 2 and come into contact with the bottom of the cardboard stack. The four receiving posts 12 on the receiving platform 1 leave a certain gap between the bottom of the cardboard stack and the top of the receiving plate 2, which is convenient for workers to handle. When the cardboard stack reaches the preset height, the baffle plate 3 is removed to remove the obstruction to the cardboard. At this time, the cardboard stack has a gap due to the support of the receiving posts, and it can be directly transported away by inserting a handling tool into the bottom.
